In general, embodiments of the invention relate to systems, devices, and methods for providing computer implemented services. To provide computer implemented services, resources may need to be allocated for the performance of the services. The resources may include, for example, compute resources, control resources, and hardware resources.
To allocate the resources, composed information handling systems may be instantiated. A composed information handling system may be a device (the components of which may be distributed across one or more information handling systems) that has exclusive use over a quantity of resources. Resources from multiple information handling systems may be allocated to a composed information handling system thereby enabling a composed information handling system to utilize resources from any number of information handling system for performance of corresponding computer implemented services.
Once a composed information handling system has been instantiated one or more resources in the composed information handling system may transition to a compromised state, e.g., the resource is likely to fail, the resource has failed, etc. When the resource is in a compromised state, the resource should be replaced in order for the composed information handling system to continue to operate in a manner that is expected by the user. Embodiment of the invention enable automatic healing of such resources uses, e.g., a combination of replacement option information (ROI) and replacement conditions. The ROI may specify, e.g., whether the resource is hot replaceable or reboot replaceable. The replacement conditions specify the timeframe for replacement, e g, immediately (or soon), when the composed information handling system next reboots, etc.
The information handling system of the system of
To provide computer implemented services, the information handling systems (60) may utilize resources provided by hardware resources. The resources may include, for example, processing resources, storage resources, memory resources, graphics processing resources, communications resources, and/or other types of resources provided by the hardware resources. Various hardware resources may provide these resources.
The type and quantity of resources required to provide computer implemented services may vary depending on the type and quantity of computer implemented services to be provided. For example, some types of computer implemented services may be more compute intensive (e.g., modeling) while other computer implemented services may be more storage intensive (e.g., database) thereby having different computing resource requirements for these different services. Consequently, resources may be used inefficiently if the quantity of resources are over-allocated for the computer implemented services. Similarly, the quality of the provided computer implemented services may be poor or otherwise undesirable if resources are under-allocated for the computer implemented services.
Clients (40) may request that the computer implemented services be provided. For example, the clients (40) may send requests to management entities to have the computer implemented services be provided.
In general, embodiments of the invention relate to system, methods, and devices for managing the hardware resources of the information handling systems (60) and/or other resources (e.g., external resources (30)) to provide computer implemented services. The hardware resources of the information handling systems (60) may be managed by instantiating one or more composed information handling systems using the hardware resources of the information handling systems (60), external resources (30), and/or other types of hardware resources operably connected to the information handling systems (60). Consequently, the resources allocated to a composed information handling system may be tailored to the specific needs of the services that will be provided by the composed information handling system.
Overtime, the quantity of resources necessary to provide the computer implemented services may change. In such scenarios, the resource allocations for providing the services may be modified. For example, additional resources may be added to existing composed information handling systems (e.g., when over-loaded), resources may be removed from existing composed information handling systems (e.g., when under-loaded), and/or new composed information handling systems may be instantiated so that some of the existing workloads hosted by composed information handling systems can be transferred to the new composed information handling systems. By doing so, embodiments of the invention may improve the likelihood that computer implemented services are provided in a manner that meets the expectations of the clients (40).
In one or more embodiments of the invention, the system includes a system control processor manager (50). The system control processor manager (50) may provide composed information handling system composition services. Composed information handling system composition services may include (i) obtaining composition requests for composed information handling systems from, for example, the clients (40), (ii) aggregating resources from the information handling systems (60) and/or external resources (30) using system control processors to service the composition requests by instantiating composed information handling systems in accordance with the requests, and (iii) modifying existing resource allocations (including, via, servicing decomposition requests) for composed information handling systems. By doing so, instantiated composed information handling systems may provide computer implemented services in accordance with the expectations of the clients.
To determine the utilization of the resources of the information handling systems (60), performance of workloads, or other indicators regarding the quality of computer implemented services provided by composed information handling systems, the system control processor manager (50) may instruct system control processors of the composed information handling systems to monitor the use of hardware resources by the clients (40). This information may be used, for example, to ascertain whether additional or fewer resources should be allocated to the composed information handling systems, to identify whether new composed information handling systems should be instantiated, to determine whether any of the resources are in a compromised state, and/or for other purposes.
In one or more embodiments of the invention, the system control processor manager (50) instantiates composed information handling systems in accordance with a three resource set model. As will be discussed in greater detail below, the resources of an information handling system may be divided into three logical resource sets: a compute resource set, a control resource set, and a hardware resource set. Different resource sets, or portions thereof, from the same or different information handling systems may be aggregated (e.g., caused to operate as a computing device) to instantiate a composed information handling system having at least one resource set from each set of the three resource set model.
By logically dividing the resources of an information handling system into these resource sets, different quantities and types of resources may be allocated to each composed information handling system thereby enabling the resources allocated to the respective information handling system to match performed workloads. Further, dividing the resources in accordance with the three set model may enable different resource sets to be differentiated (e.g., given different personalities) to provide different functionalities. Consequently, composed information handling systems may be composed on the basis of desired functionalities rather than just on the basis of aggregate resources to be included in the composed information handling system.
Additionally, by composing composed information handling systems in this manner, the control resource set of each composed information handling system may be used to consistently deploy management services across any number of composed information handling systems. Consequently, embodiments of the invention may provide a framework for unified security, manageability, resource management/composability, workload management, and distributed system management by use of this three resource set model. For example, utilization monitors may be deployed in control resource sets to monitor the use of the other resource sets. Accordingly, use of these resources for providing computer implemented services requested by the clients (40) may be uniformly monitored across the information handling systems (60). For additional details regarding the system control processor manager (50), refer to
In one or more embodiments of the invention, a composed information handling system is a device that is formed using all, or a portion, of the resources of the information handling systems (60), the external resources (30), and/or other types of hardware resources operably connected to the information handling systems (60). The composed information handling system may utilize the resources allocated to it to provide computer implemented services. For example, the composed information handling system may host one or more applications that utilize the resources assigned to the composed information handling system. The applications may provide the computer implemented services. Thus, the quality of the computer implemented services may be limited based on the allocation of resources to the composed information handling systems.
To instantiate composed information handling systems, the information handling systems (60) may include at least three resource sets including a control resource set. The control resource set may include a system control processor. The system control processor of each information handling system may coordinate with the system control processor manager (50) to enable composed information handling systems to be instantiated. For example, the system control processor of an information handling system may provide telemetry data regarding the resources of an information handling system, may perform actions on behalf of the system control processor manager (50) to aggregate resources together, may monitor the utilization of resources for providing computer implemented services requested by the clients (40), and/or may provide services that unify the operation of composed information handling systems.
In one or more embodiments of the invention, compute resource sets of composed information handling systems are presented with bare metal resources by control resource sets even when the presented resources are actually being managed using one or more layers of abstraction, emulation, virtualization, security model, etc. For example, the system control processors of the control resource sets may provide the abstraction, emulation, virtualization, and/or other services while presenting the resources as bare metal resources. Consequently, these services may be transparent to applications hosted by the compute resource sets of composed information handling systems thereby enabling uniform deployment of such services without requiring implementation of control plane entities hosted by the compute resource sets of the composed information handling systems. Accordingly, by utilizing system control processors to monitor the use of the resources of a composed information handling system, applications or other entities hosted by the composed information handling system may not be able to view, be aware, impact, or otherwise influence the collection of computing resource use data. Accordingly, relevant information that may be used to decide how to allocate resources may be obtain in a manner that is transparent to the composed information handling systems. For additional details regarding the information handling systems (60), refer to
The external resources (30) may provide resources that may be allocated for use by composed information handling systems. For example, the external resources (30) may include hardware resources that provide any number and type of resources. The composed information handling system may use these resources to provide their functionalities. For example, system control processors may operably connect to and manage the external resources (30) to provide additional and/or different resources from those available to be provided only using hardware resource sets of information handling systems. By utilizing system control processors to manage these resources, the use of these external resources (30) for providing services requested by the clients (40) may also be efficiently and transparently monitored.
Different external resources (e.g., 32, 34) may provide similar or different resources. For example, some external resources may include large numbers of hard disk drives to provide storage resources while other may include graphics processing unit rendering farms. The external resources (30) may include any number and type of resources for allocation to composed information handling systems via system control processors of control resource sets.
The system of
The clients (40), system control processor manager (50), information handling systems (60), and/or external resources (30) may be implemented using computing devices. The computing devices may include, for example, a server, laptop computer, a desktop computer, a node of a distributed system, etc. The computing device may include one or more processors, memory (e.g., random access memory), and/or persistent storage (e.g., disk drives, solid state drives, etc.). The persistent storage may store computer instructions, e.g., computer code, that (when executed by the processor(s) of the computing device) cause the computing device to perform the functions of the system control processor manager (50), information handling systems (60), and/or external resources (30) described in this application and/or all, or a portion, of the methods illustrated in
While the system of
Turning to
As discussed above, the information handling system (100) may provide any quantity and type of computer implemented services. To provide the computer implemented services, resources of the information handling system may be used to instantiate one or more composed information handling systems. The composed information handling systems may provide the computer implemented services.
To provide computer implemented services, the information handling system (100) may include any number and type of hardware resources (also referred to as resources) including, for example, one or more processors (106), any quantity and type of processor dedicated memory (104), one or more system control processors (114), and any number of hardware resources (118). These hardware resources may be logically divided into three resource sets including a compute resource set (102), a control resource set (108), and a hardware resource set (110).
The control resource set (108) of the information handling system (100) may facilitate formation of composed information handling systems. To do so, the control resource set (108) may prepare any quantity of resources from any number of hardware resource sets (e.g., 110) (e.g., of the information handling system (100) and/or other information handling systems) for presentation to processing resources of any number of computing resource sets (e.g., 102) (e.g., of the information handling system (100) and/or other information handling systems). Once prepared, the control resource set (108) may present the prepared resources as bare metal resources to the processors (e.g., 106) of the allocated resources. By doing so, a composed information handling system may be instantiated.
To prepare the resources of the hardware resource sets for presentation, the control resource set (108) may employ, for example, virtualization, indirection, abstraction, and/or emulation. These management functionalities may be transparent to applications hosted by the resulting instantiated composed information handling systems. Consequently, while unknown to the control plane entities of the composed information handling system, the composed information handling system may operate in accordance with any number of management models thereby providing for unified control and management of composed information handling systems. These functionalities may be transparent to applications hosted by composed information handling systems thereby relieving them from overhead associated with these functionalities.
For example, consider a scenario where a control resource set is instructed to instantiate a composed information handling system including a compute resource set and a hardware resource set that will contribute storage resources to the compute resource set. The control resource set may virtualize the storage resources of the hardware resource set to enable a select quantity of the storage resources to be allocated to the composed information handling system while reserving some of the storage resources for allocation to other composed information handling systems. However, the prepared storage resources may be presented to the compute resource set as bare metal resources. Consequently, the compute resource set may not need to host any control plane entities or otherwise incur overhead for utilizing the virtualized storage resources (e.g., the compute resource set may send bare metal communications to the control resource set, the control resource set may translate those bare metal communications into prepared resource compatible communications, and the control resource set may send the prepared resource compatible communications to the hardware resource set).
The control resource set (108) may also enable the utilization of any of the hardware components of the information handling system (100) by respective clients. When a composed information handling system is instantiated, it (and its hardware resources) may be utilized by a client by enabling the client to load application onto the composed information handling system. For example, the client may cause the composed information handling system to execute applications on the compute resource set (102) which, in turn, may utilize any number of hardware resource sets (e.g., 110) as part of their execution.
Because the control resource set (108) may mediate utilization of hardware resource sets (110) by compute resource sets (102), the control resource set (108) may transparently ascertain the use of the hardware resources of these resource sets, workloads being performed, and/or other information indicative of load states of the composed information handling systems (and/or quality of computer implemented services being provided by the composed information handling systems). To do so, the control resource set (108) may intercept (as part of presenting resources of hardware resource sets to compute resource sets) communications between resource sets, monitor workloads being performed by each of the respective resource sets, monitor power utilization by these resource sets, and/or may perform other actions to identify the use of these hardware resources by respective clients.
The collected use information may be used, for example, to ascertain whether additional resources should be added to composed information handling systems, to ascertain whether resources should be removed from composed information handling systems, to notify clients of their use of these resources (e.g., if the clients are being billed for use as part of a pay for use infrastructure deployment), to obtain information useable to estimate future computing resource requirements for hosting various applications and/or performing various types of workloads, and/or for other purposes.
The compute resource set (102) may include one or more processors (106) operably connected to the processor dedicated memory (104). Consequently, the compute resource set (102) may host any number of executing processes thereby enabling any number and type of workloads to be performed. When performing the workloads, the compute resource set (102) may utilize resources provided by the hardware resource set (110) of the information handling system (100), hardware resource sets of other information handling systems, and/or external resources.
The processors (106) of the compute resource set (102) may be operably connected to one or more system control processors (114) of the control resource set (108). For example, the processors (106) may be connected to a compute resource interface (112), which is also connected to the system control processors (114). The compute resource interface (112) may enable the processors (106) to communicate with other entities via bare metal communications. Also, the compute resource interface (112) may enable system control processors (114) of the control resource set (108) to monitor the activity of the processors (106) and/or processor dedicated memory (104) to identify use of these hardware resources by clients. For example, the compute resources interface (112) may support sideband communications to the hardware resources of the compute resource set (102) thereby enabling utilization information for these hardware resources to be obtained by the system control processors (114).
The system control processors (114) of the control resource set (108) may present resources to the processors (106) as bare metal resources. In other words, from the point of view of the processors (106), any number of bare metal resources may be operably connected to it via the compute resources interface (112) when, in reality, the system control processors (114) are operably connected to the processors (106) via the compute resources interface (112). In other words, the system control processors (114) may manage presentation of other types of resources (e.g., resources of the hardware resource set (110)), external resources, other hardware resource sets of other information handling systems, etc.) to the compute resource set (102).
By presenting the resources to the processors as bare metal resources, control plane entities (e.g., applications) such as hypervisors, emulators, and/or other types of management entities may not need to be hosted (e.g., executed) by the processors (106) for the processors (106) and entities hosted by them to utilize the resources allocated to a composed information handling system. Accordingly, all of the processing resources provided by the compute resource set (102) may be dedicated to providing the computer implemented services.
For example, the processors (106) may utilize mapped memory addresses to communicate with the bare metal resources presented by the system control processors (114) to the processors (106). The system control processors (114) may obtain these communications and appropriately remap (e.g., repackage, redirect, encapsulate, etc.) the communications to the actual hardware resources providing the resources, which the processors (106) are interacting with via the compute resources interface (112) and/or hardware resources interface (116), discussed below. Consequently, indirection, remapping, and/or other functions required for resource virtualization, emulation, abstraction, or other methods of resource allocation (other than bare metal) and management may not need to be implemented via the processors (106).
By doing so, any number of functions for a composed information handling system may be automatically performed in a manner that is transparent to the control plane. Accordingly, a composed information handling system may operate in a manner consistent with a unified, consistent architecture or model (e.g., communications model, data storage model, etc.) by configuring the operation of one or more system control processors in a manner consistent with the architecture or model.
In one or more embodiments of the invention, control plane entities utilize resources presented through one or more layers of indirection, abstraction, virtualization, etc. In other words, an indirect use of hardware resources and resources provided thereby. In the information handling system of
In one or more embodiments of the invention, data plane entities directly utilize resources. For example, data plane entities may instruct hardware resources on their operation thereby directly utilizing resources provided thereby. Data plane entities may present the resources to control plane entities using one or more layers of indirection, abstraction, virtualization, etc.
The system control processors (114) may present any number of resources operably connected to it (e.g., the hardware resource set (110)), other resources operably connected to it via an interface (e.g., hardware resources interface (116), etc.) as bare metal resources to the processors (106) of the compute resource set (102). Consequently, the system control processors (114) may implement device discovery processes compatible with the processors (106) to enable the processors (106) to utilize the presented resources.
For example, the hardware resource set (110) may include hardware resources (118) operably connected to the system control processors (114) via a hardware resources interface (116). The hardware resources (118) may include any number and type of hardware resources that provide resources. For additional details regarding the hardware resources (118), refer to
In another example, the system control processors (114) may be operably connected to other hardware resource sets of other information handling systems via hardware resources interface (116), network (130), and/or other system control processors of the other information handling systems. The system control processors may cooperatively enable hardware resource sets of other information handling systems to be prepared and presented as bare metal resources to the compute resource set (102).
In an additional example, the system control processors (114) may be operably connected to external resources via hardware resources interface (116) and network (130). The system control processors (114) may prepare and present the external resources as bare metal resources to the compute resource set (102).
The system control processors (114), by presenting resources to the compute resource set (102), may be able to monitor the utilization of the presented resources in a manner that is transparent to the applications or other entities executing using the processors (106). Consequently, these entities may not be able to interfere with monitoring of the use of these resources. In contrast, if an agent or other entity for monitoring computing resource use rates is executing using the processors (106), other entities executing using the processors (106) may be able to interfere with the operation of the monitoring entity. Accordingly, embodiments of the invention may provide a method of monitoring resources use that is less susceptible to interference by other entities. By doing so, resource allocation decisions made based on the collected information may better reflect the actual use of resources by the composed information handling systems.
For additional details regarding the operation and functions of the system control processors (114), refer to
The compute resources interface (112) may be implemented using any suitable interconnection technology including, for example, system buses such as compute express links or other interconnection protocols. The compute resources interface (112) may support any input/output (IO) protocol, any memory protocol, any coherence interface, etc. The compute resources interface (112) may support processor to device connections, processor to memory connections, and/or other types of connections. The compute resources interface (112) may be implemented using one or more hardware resources including circuitry adapted to provide the functionality of the compute resources interface (112).
The compute resources interface (112) may also support sideband communications between the system control processors (114), the processors (106), and/or the processor dedicated memory (104). Consequently, the system control processors (114) may be able to monitor the operations of these other devices to identify the utilization of these hardware resources by clients, identify workloads being performed by these devices, etc.
The hardware resources interface (116) may be implemented using any suitable interconnection technology including, for example, system buses such as compute express links or other interconnection protocols. The hardware resources interface (116) may support any input/output (IO) protocol, any memory protocol, any coherence interface, etc. The hardware resources interface (116) may support processor to device connections, processor to memory connections, and/or other types of connections. The hardware resources interface (116) may be implemented using one or more hardware resources including circuitry adapted to provide the functionality of the hardware resources interface (116).
In some embodiments of the invention, the compute resource set (102), control resource set (108), and/or hardware resource set (110) may be implemented as separate physical devices. In such a scenario, the compute resources interface (112) and hardware resources interface (116) may include one or more networks enabling these resource sets to communicate with one another. Consequently, any of these resource sets (e.g., 102, 108, 110) may include network interface cards or other devices to enable the hardware resources of the respective resource sets to communicate with each other.
In one or more embodiments of the invention, the system control processors (114) support multiple, independent connections. For example, the system control processors (114) may support a first network communications connection (e.g., an in-band connection) that may be allocated for use by applications hosted by the processors (106). The system control processors (114) may also support a second network communications connection (e.g., an out-of-band connection) that may be allocated for use by applications hosted by the system control processors (114). The out-of-band connection may be utilized for management and control purposes while the in-band connection may be utilized to provide computer implemented services. These connections may be associated with different network endpoints thereby enabling communications to be selectively directed toward applications hosted by the processors (106) and/or system control processors (114). As will be discussed in greater detail with respect to
The network (130) may correspond to any type of network and may be operably connected to the Internet or other networks thereby enabling the information handling system (100) to communicate with any number and type of other devices.
The information handling system (100) may be implemented using computing devices. The computing devices may be, for example, a server, laptop computer, desktop computer, node of a distributed system, etc. The computing device may include one or more processors, memory (e.g., random access memory), and/or persistent storage (e.g., disk drives, solid state drives, etc.). The persistent storage may store computer instructions, e.g., computer code, that (when executed by the processor(s) of the computing device) cause the computing device to perform the functions of the information handling system (100) described in this application and/or all, or a portion, of the methods illustrated in
While the information handling system (100) has been illustrated and described as including a limited number of specific components, an information handling system in accordance with embodiments of the invention may include additional, fewer, and/or different components without departing from the invention.
Turning to
The hardware resources (118) may include any number and types of hardware resources that may provide any quantity and type of resources. For example, the hardware resources (118) may include storage devices (200), memory devices (202), and special purpose devices (204).
The storage devices (200) may provide storage resources (e.g., persistent storage) in which applications hosted by a composed information handling system may store data including any type and quantity of information. The storage devices (200) may include any type and quantity of devices for storing data. The devices may include, for example, hard disk drives, solid state drives, tape drives, etc. The storage devices (200) may include other types of devices for providing storage resources without departing from the invention. For example, the storage devices (200) may include controllers (e.g., redundant array of disk controllers), load balancers, and/or other types of devices.
The memory devices (202) may provide memory resources (e.g., transitory and/or persistent storage) in which a composed information handling system may store data including any type and quantity of information. The memory devices (202) may include any type and quantity of devices for storing data. The devices may include, for example, transitory memory such as random access memory, persistent memory such as storage class memory, etc. The memory devices (202) may include other types of devices for providing memory resources without departing from the invention. For example, the storage devices (200) may include controllers (e.g., replication managers), load balancers, and/or other types of devices.
The special purpose devices (204) may provide other types of resources (e.g., graphics processing resources, computation acceleration resources, etc.) to composed information handling systems. The special purpose devices (204) may include any type and quantity of devices for providing other types of resources. The special purpose devices (204) may include, for example, graphics processing units for providing graphics processing resources, compute accelerators for accelerating corresponding workloads performed by composed information handling systems, application specific integrated circuits (ASICs) for performing other functionalities, digital signal processors for facilitating high speed communications, field programmable gate arrays to perform customized computing functionalities, etc. The special purpose devices (204) may include other types of devices for providing other types of resources without departing from the invention.
The system control processors of the information handling systems may mediate presentation of the resources provided by the hardware resources (118) to computing resource sets (e.g., as bare metal resources to processors). When doing so, the system control processors may provide a layer of abstraction that enables the hardware resources (118) to be, for example, virtualized, emulated as being compatible with other systems, and/or directly connected to the compute resource sets (e.g., pass through). Consequently, the resources of the hardware resources (118) may be finely, or at a macro level, allocated to different composed information handling systems.
Additionally, the system control processors may manage operation of these hardware resources in accordance with one or more models including, for example, data protection models, security models, workload performance availability models, reporting models, etc. For example, the system control processors may cause multiple copies of data to be redundantly stored, to be stored with error correction code, and/or other information usable for data integrity purposes.
The manner of operation of these devices may be transparent to the computing resource sets utilizing these hardware resources for providing computer implemented services. Consequently, even though the resulting composed information handling system control plane may be unaware of the implementation of these models, the composed information handling systems may still operate in accordance with these models thereby providing a unified method of managing the operation of composed information handling systems.
Further, the system control processors may monitor the use of these hardware resources by clients. As will be discussed below, the system control processors may host applications that monitor communications indicative of utilization of these hardware resources to determine whether additional resources should be allocated to them, whether resources should be deallocated from them, whether new instances of composed information handling systems should be instantiated, etc.
While the hardware resources (118) have been illustrated and described as including a limited number of specific components, local hardware resources in accordance with embodiments of the invention may include additional, fewer, and/or different components without departing from the invention.
As discussed above, information handling systems may include system control processors that may be used to instantiate composed information handling systems.
The system control processor (298) may facilitate instantiation, reallocation of resources to/from composed systems, operation, and decomposition of composed information handling systems. By doing so, a system that includes information handling systems may dynamically instantiate, recompose (, and decompose composed information handling systems.
To perform one or more of the aforementioned functionalities for/to the composed information handling systems, the system control processor (298) may include a composition manager (300), a utilization manager (301), a physical resources manager (302), an emulated resources manager (304), a virtual resources manager (306), an operation manager (308), hardware resource services (310), and storage (312). Each of these components of the system control processor is discussed below.
The composition manager (300) may manage the process of instantiating, operating, and decomposing composed information handling systems. To provide these management services, the composition manager (300) may include functionality to (i) obtain information regarding the hardware components of the information handling system (e.g., obtain telemetry data regarding the information handling system), (ii) provide the obtained information to other entities (e.g., management entities such as system control processor manager (50,
To obtain information regarding the hardware components of the information handling system, the composition manager (300) may inventory the components of the information handling system hosting the system control processor. The inventory may include, for example, the type and model of each hardware component, versions of firmware or other code executing on the hardware components, and/or information regarding hardware components of the information handling system that may be allocated to form composed information handling systems.
The composition manager (300) may obtain composition requests from other entities (e.g., management entities tasked with instantiating composed information handling systems), as pre-loaded instructions present in storage of the system control processor, and/or via other methods. The composition requests may specify, for example, the types and quantities of resources to be allocated to a composed information handling system.
In one or more embodiments of the invention, the composition requests specify the computing resource allocations using an intent based model. For example, rather than specifying specific hardware resources (or portions thereof) to be allocated to a particular compute resource set to obtain a composed information handling system, the resource requests may only specify that a composed information handling system is to be instantiated having predetermined characteristics, that a composed information handling system will perform certain workloads or execute certain applications, and/or that the composed information handling system be able to perform one or more predetermined functionalities. In such a scenario, the composition manager may decide how to instantiate the composed information handling system (e.g., which resources to allocate, how to allocate the resources (e.g., virtualization, emulation, redundant workload performance, data integrity models to employ, etc.), to which compute resource set(s) to present corresponding resources, etc.).
In one or more embodiments of the invention, the composition requests specify the computing resource allocations using an explicit model. For example, the composition requests may specify (i) the resources to be allocated, (ii) the manner of presentation of those resources (e.g., emulating a particular type of device using a virtualized resource vs. path through directly to a hardware component), and (iii) the compute resource set(s) to which each of the allocated resources are to be presented.
In addition to specifying resource allocations, the composition requests may also specify, for example, applications to be hosted by the composed information handling systems, security models to be employed by the composed information handling systems, communication models to be employed by the composed information handling systems, services to be provided to the composed information handling systems, user/entity access credentials for use of the composed information handling systems, and/or other information usable to place the composed information handling systems into states in which the composed information handling systems provide desired computer implemented services.
To prepare and present resources to compute resource sets based on the composition requests, the system control processors may implement, for example, abstraction, indirection, virtualization, mapping, emulation, and/or other types of services that may be used to present any type of resources as a resource that is capable of bare metal utilization by compute resource sets. To provide these services, the composition manager (300) may invoke the functionality of the physical resources manager (302), the emulated resources manager (304), and/or the virtual resources manager (306).
When presenting the resources to the compute resource sets, the system control processor (298) may present the resources using an emulated data plane. For example, the system control processors (298) may receive bare metal communications (e.g., IO from the processors that presumes a direct connection to another hardware resource) and respond in a manner consistent with responses of corresponding bare metal devices (e.g., memory). When doing so, the system control processor (298) may translate the communications into actions. The actions may be provided to the hardware resources used by the system control processor (298) to present the bare metal resources to the compute resource set(s). In turn, the hardware resources may perform the actions which results in a composed information handling system providing desired computer implemented services.
In some scenarios, multiple system control processors may cooperate to present bare metal resources to a compute resource set. For example, a single information handling system may not include sufficient hardware resources to present a quantity and/or type of resources to a compute resource set as specified by a composition request (e.g., present two storage devices to a compute resource set when a single information handling system only includes a single storage device). In this scenario, a second system control processor of a second information handling system operably connected to the system control processor tasked with presenting the resources to a compute resource set may prepare one of its storage devices for presentation. Once prepared, the second system control processor may communicate with the system control processor to enable the system control processor to present the prepared storage device (i.e., the storage device in the information handling system) to the compute resource set. By doing so, resources from multiple information handling systems may be aggregated to present a desired quantity of resources to compute resource set(s) to form a composed information handling system.
By forming composed information handling systems as discussed above, embodiments of the invention may provide a system that is able to effectively utilize distributed resources across a range of devices to provide computer implemented services.
In addition to enabling the composition of composed information handling system the composition manager (300) may also include functionality to decompose all or a portion of a composed information handling system.
When providing its functionality, the composition manager (300) may perform all, or a portion, of the methods illustrated in
After a composed information handling system is formed, a client may begin to utilize the hardware resources of the composed information handling system, by causing desired computer implemented services to be provided using the hardware resources. The utilization manager (301) may monitor the use of these hardware resources by the client to ascertain whether the services provided, using these hardware resources, meet the expectations of the client. For example, if a hardware resource is likely to enter a compromised state, the computer implemented services provided by a composed information handling system may no longer be able to meet the client's expectations.
To do so, the utilization manager (301) may monitor the health of the hardware resources used to provide resources to the composed information handling system. If the utilization manager (301) identifies, based on its monitoring, that one or more hardware resources are likely to fail, or has failed, the utilization manager (301) may initiate the method shown in
In one or more embodiments of the invention, the utilization manager (301) invokes native health reporting functionality of hardware resources when providing its functionality. By doing so, the utilization manager (301) may obtain information indicating the relatively likelihood of the hardware resources being able to continue to supply resources.
In one or more embodiments of the invention, the utilization manager (301) utilizes intercepted bare metal communications from compute resource sets when providing its functionality. For example, when the system control processor (298) mediates presentations of resources, it may obtain bare metal communications. The utilization manager (301) may review the content of these communications to ascertain whether hardware resources may be likely to enter compromised states. To do so, the utilization manager (301) may look for duplicative requests, delays between requests and responses, and/or other indications that a hardware resource may not be operating nominally (e.g., as expected, within an accepted range, etc.). By doing so, the utilization manager (301) may obtain information indicating the relatively likelihood of the hardware resources being able to continue to supply resources.
When providing its functionality, the utilization manager (301) may perform all, or a portion, of the methods illustrated in
The physical resources manager (302) may manage presentation of resources to compute resource sets. For example, the physical resources manager (302) may generate, for example, translation tables that specify actions to be performed in response to bare metal communications obtained from compute resource sets. The translation tables may be used to take action in response to communications from compute resource sets.
The physical resources manager (302) may generate the translation tables based on the components of the compute resource sets, allocations or other types of commands/communications obtained from the compute resource sets, and the resources of the information handling system(s) allocated to service the compute resource set. For example, when a compute resource set is presented with a bare metal resource, it may go through a discovery process to prepare the bare metal resource for use. As the discovery process proceeds, the compute resource set may send commands/communications to the bare metal resource to, for example, discover its address range. The physical resources manager (302) may monitor this process, respond appropriately, and generate the translation table based on these commands and the resources available to service these bare metal commands/communications (e.g., to obtain address translation tables, emulation tables, etc.).
For example, consider a scenario where a virtualized disk is allocated to service bare metal storage commands from a compute resource set. In such a scenario, the physical resources manager (302) may generate a translation table that translates physical write from the compute resource set to virtualized writes corresponding to the virtualized disk. Consequently, the virtualized disk may be used by the system control processor (298) to present bare metal resources to the compute resource set.
The emulated resources manager (304) may generate emulation tables that enable resources that would otherwise be incompatible with a compute resource set to be compatible with the compute resource set. Different types of hardware resources of a compute resource set may be compatible with different types of hardware resources. Consequently, resources allocated to provide bare metal resources may not necessarily be compatible with the hardware resources of a compute resource set. The emulated resources manager (304) may generate emulation tables that map bare metal communications obtained from a compute resource set to actions that are compatible with resources allocated to provide bare metal resources to the compute resource sets.
The virtual resources manager (306) may manage virtualized resources that may be allocated to provide bare metal resources to compute resource sets. For example, the virtual resources manager (306) may include hypervisor functionality to virtualized hardware resources and allocate portions of the virtualized resources for use in providing bare metal resources.
While the physical resources manager (302), emulated resources manager (304), and virtual resources manager (306) have been described as generating tables, these components of the system control processor may generate other types of data structures or utilize different management models to provide their respective functionalities without departing from the invention.
The functionalities of the physical resources manager (302), emulated resources manager (304), and virtual resources manager (306) may be utilized in isolation and/or combination to provide bare metal resources to compute resource sets. By doing so, the system control processor (298) may address compatibility issues, sizing issues to match available resources to those that are to be allocated, and/or other issues to enable bare metal resources to be presented to compute resource sets.
When providing bare metal resources, the composition manager (300) may invoke the functionality of the physical resources manager (302), emulated resources manager (304), and virtual resources manager (306). Consequently, resources may be presented as bare metal resources via pass-through (i.e., forwarding IO from compute resource sets to hardware resources), bare metal resource addressing of virtualized resources, and/or as emulated resources compatible with the hardware components of the compute resource set.
The functionality of the physical resources manager (302), emulated resources manager (304), and virtual resources manager (306) may be invoked using any communication model including, for example, message passing, state sharing, memory sharing, etc.
The operation manager (308) may manage the general operation of the system control processor (298). For example, the operation manager (308) may operate as an operating system or other entity that manages the resources of the system control processor (298). The composition manager (300), utilization manager (301), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), and/or other entities hosted by the system control processor (298) may call or otherwise utilize the operation manager (308) to obtain appropriate resources (e.g., processing resources, memory resources, storage, communications, etc.) to provide their functionalities.
The hardware resource services (310) may facilitate use of the hardware components of any number of hardware resource sets (e.g., 110,
When providing their functionalities, any of the aforementioned components of the system control processor (298) may perform all, or a portion, of the methods illustrated in
The system control processor (298) may be implemented using computing devices. The computing devices may be, for example, an embedded computing device such as a system on a chip, a processing device operably coupled to memory and storage, or another type of computing device. The computing device may include one or more processors, memory (e.g., random access memory), and/or persistent storage (e.g., disk drives, solid state drives, etc.). The persistent storage may store computer instructions, e.g., computer code, that (when executed by the processor(s) of the computing device) cause the computing device to perform the functions of the system control processor (298) described in this application and/or all, or a portion, of the methods illustrated in
In one or more embodiments of the invention, the system control processor (298) is implemented as an on-board device. For example, the system control processor (298) may be implemented using a chip including circuitry disposed on a circuit card. The circuit card may also host the compute resource sets and/or hardware resource sets managed by the system control processor (298).
In one or more embodiments of the invention, any of the composition manager (300), utilization manager (301), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), operation manager (308), and/or hardware resource services (310) are implemented using a hardware resource including circuitry. The hardware resource may be, for example, a digital signal processor, a field programmable gate array, or an application specific integrated circuit. The circuitry may be adapted to cause the hardware resource to perform the functionality of the composition manager (300), utilization manager (301), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), operation manager (308), and/or hardware resource services (310). The composition manager (300), utilization manager (301), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), operation manager (308), and/or hardware resource services (310) may be implemented using other types of hardware resources without departing from the invention.
In one or more embodiments of the invention, any of the composition manager (300), utilization manager (301), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), operation manager (308), and/or hardware resource services (310) are implemented using a processor adapted to execute computing code stored on a persistent storage (e.g., as part of the system control processor (298) or operably connected to the system control processor (298) thereby enabling processors of the system control processor (298) to obtain and execute the computing code) that when executed by the processor performs the functionality of the composition manager (300), utilization manager (301), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), operation manager (308), and/or hardware resource services (310). The processor may be a hardware processor including circuitry such as, for example, a central processing unit or a microcontroller. The processor may be other types of hardware resources for processing digital information without departing from the invention.
As used herein, an entity that is programmed to perform a function (e.g., step, action, etc.) refers to one or more hardware resources (e.g., processors, digital signal processors, field programmable gate arrays, application specific integrated circuits, etc.) that provide the function. The hardware resources may be programmed to do so by, for example, being able to execute computer instructions (e.g., computer code) that cause the hardware resources to provide the function. In another example, the hardware resource may be programmed to do so by having circuitry that has been adapted (e.g., modified) to perform the function. An entity that is programmed to perform a function does not include computer instructions in isolation from any hardware resources. Computer instructions may be used to program a hardware resource that, when programmed, provides the function.
In one or more embodiments disclosed herein, the storage (312) is implemented using physical devices that provide data storage services (e.g., storing data and providing copies of previously stored data). The devices that provide data storage services may include hardware resources and/or logical devices. For example, storage (312) may include any quantity and/or combination of memory devices (i.e., volatile storage), long term storage devices (i.e., persistent storage), other types of hardware resources that may provide short term and/or long term data storage services, and/or logical storage devices (e.g., virtual persistent storage/virtual volatile storage).
For example, storage (312) may include a memory device (e.g., a dual in line memory device) in which data is stored and from which copies of previously stored data are provided. In another example, storage (312) may include a persistent storage device (e.g., a solid-state disk drive) in which data is stored and from which copies of previously stored data is provided. In a still further example, storage (312) may include (i) a memory device (e.g., a dual in line memory device) in which data is stored and from which copies of previously stored data are provided and (ii) a persistent storage device that stores a copy of the data stored in the memory device (e.g., to provide a copy of the data in the event that power loss or other issues with the memory device that may impact its ability to maintain the copy of the data cause the memory device to lose the data).
The storage (312) may also be implemented using logical storage. A logical storage (e.g., virtual disk) may be implemented using one or more physical storage devices whose storage resources (all, or a portion) are allocated for use using a software layer. Thus, a logical storage may include both physical storage devices and an entity executing on a processor or other hardware resource that allocates the storage resources of the physical storage devices.
The storage (312) may store data structures including, for example, composed information handling system data (314), a resource map (316), and a resource utilization map (318). Each of these data structures is discussed below.
The composed information handling system data (314) may be implemented using one or more data structures that includes information regarding composed information handling systems. For example, the composed information handling system data (314) may specify identifiers of composed information handling systems and resources that have been allocated to the composed information handling systems.
The composed information handling system data (314) may also include information regarding the operation of the composed information handling systems. The information may include, for example, workload performance data, resource utilization rates over time, and/or other information that may be utilized to manage the operation of the composed information handling systems.
The composed information handling system data (314) may further include information regarding management models employed by system control processors. For example, the composed information handling system data (314) may include information regarding duplicative data stored for data integrity purposes, redundantly performed workloads to meet high availability service requirements, encryption schemes utilized to prevent unauthorized access of data, etc.
The composed information handling system data (314) may be maintained by, for example, the composition manager (300). For example, the composition manager may add, remove, and/or modify information included in the composed information handling system data (314) to cause the information included in the composed information handling system data (314) to reflect the state of the composed information handling systems.
The data structures of the composed information handling system data (314) may be implemented using, for example, lists, tables, unstructured data, databases, etc. While illustrated in
The resource map (316) may be implemented using one or more data structures that include information regarding resources of the information handling system and/or other information handling systems. For example, the resource map (316) may specify the type and/or quantity of resources (e.g., hardware resources, virtualized devices, etc.) available for allocation (i.e., in an allocatable state) and/or that are already allocated to composed information handling systems. The resource map (316) may be used to provide data to management entities such as system control processor managers.
The data structures of the resource map (316) may be implemented using, for example, lists, tables, unstructured data, databases, etc. While illustrated in
The resource map (316) may be maintained by, for example, the composition manager (300). For example, the composition manager (300) may add, remove, and/or modify information included in the resource map (316) to cause the information included in the resource map (316) to reflect the state of the information handling system and/or other information handling systems.
The resource utilization map (318) may be implemented using one or more data structures that includes information regarding the utilization of hardware resources of the composed information handling systems, workloads being performed by the hardware resources, and/or other types of information that may be used to ascertain the quality of computer implemented services being provided by a composed information handling system. For example, the resource utilization map (318) may specify identifiers of hardware resources of a composed information handling system, the workloads being performed by these hardware resources, the utilization rates of these hardware resources, etc.
The resource utilization map (318) may specify the resource utilization via any method. For example, the resource utilization map (318) map may specify a quantity of utilization, resource utilization rates over time, power consumption of hardware resources while utilized to provide the computer implemented services, workload (and/or statuses) performed using hardware resources, etc. The resource utilization map (318) may include other types of information used to quantify the quality of computer implemented services provided without departing from the invention.
The resource utilization map (318) may also specify the health states of hardware devices via any method. For example, the resource utilization map (318) may indicate whether, based on the aggregated health information, the hardware devices are, or are not, in a compromised state. A compromised health state may indicate that the corresponding hardware device has already or is likely to, in the future, be no longer able to provide the resources that it has previously provided. The health state determination may be made via any method based on the aggregated health information without departing from the invention.
For example, the health state determination may be made based on heuristic information regarding previously observed relationships between health information and future outcomes (e.g., current health information being predictive of whether a hardware device will be likely to provide resources in the future).
The resource utilization map (318) may be maintained by, for example, the utilization manager (301). For example, the utilization manager (301) may add, remove, and/or modify information included in the resource utilization map (318), to cause the information included in the resource utilization map (318), to reflect the current health of the hardware devices that provide resources to composed information handling systems.
The resource utilization map (318) may be maintained by, for example, the utilization manager (301). For example, the utilization manager (301) may add, remove, and/or modify information included in the resource utilization map (318) to cause the information included in the resource utilization map (318) to reflect the current utilization of the composed information handling systems.
The data structures of the resource utilization map (318) may be implemented using, for example, lists, tables, unstructured data, databases, etc. While illustrated in
While the storage (312) has been illustrated and described as including a limited number and type of data, a storage in accordance with embodiments of the invention may store additional, less, and/or different data without departing from the invention.
While the system control processor (298) has been illustrated and described as including a limited number of specific components, a system control processor in accordance with embodiments of the invention may include additional, fewer, and/or different components without departing from the invention.
As discussed above, a system control processor manager may cooperate with system control processors of control resource sets to instantiate composed information handling systems by presenting resources from hardware resource sets to processors of compute resource sets.
The system control processor manager (50) may manage the process of instantiating composed information handling systems and recomposing composed information handling systems over time. To do so, the system control processor manager (50) may include an infrastructure manager (402), and storage (410). Each of these components is discussed below.
The infrastructure manager (402) may provide composition services. Composition services may include obtaining composition, recomposition, and/or decomposition requests for composed information handling systems, determining the resources to allocate to instantiate composed information handling systems, add/remove resources to recompose/decompose all or a portion of a composed information handling systems, manage transfers of workloads between composed information handling systems for recomposition purposes, and cooperating with system control processors to allocate the identified resources. By doing so, the infrastructure manager (402) may cause any number of computer implemented services to be provided using the composed information handling systems.
To determine the resources to allocate to new composed information handling systems, the infrastructure manager (402) may employ an intent based model that translates an intent expressed in a composition request to one more allocations of resources. For example, the infrastructure manager (402) may match an expressed intent to resources to be allocated to satisfy that intent. A lookup table may specify the type, quantity, method of management, and/or other information regarding any number of resources that when aggregated will be able to satisfy a corresponding intent. The infrastructure manager (402) may identify resources for allocation to satisfy composition requests via other methods without departing from the invention.
To recompose composed information handling systems, the infrastructure manager (402) may add or remove resources from existing composed information handling systems or instantiate new composed information handling systems and transfer workloads from existing composed information handling systems to the new composed information handling systems. Consequently, the composed information handling systems performing the workloads may have different amounts and/or types of resources after being recomposed.
In some embodiments of the invention, the infrastructure manager (402) may recompose deployments. A deployment may be a group of composed information handling systems performing a predetermined function. In such a scenario, the infrastructure manager (402) may recompose one or more of the composed information handling systems of the deployment to recompose the deployment.
The infrastructure manager (402) may recompose infrastructure (e.g., deployments, individual composed information handling systems, etc.) in response to recomposition requests.
To decompose composed information handling systems, the infrastructure manager (402) identify all or a portion of the resources from a composed information handling systems to be deallocated, transfer workloads from composed information handling systems of which one or more resources are to be deallocated, deallocate, after the transfer of the workload, the aforementioned identified resources.
To cooperate with the system control processors for composed information handling system composition, recomposition purposes and/or decomposition purposes, the infrastructure manager (402) may obtain telemetry data regarding the resources of any number of information handling systems and/or external resources that are available for allocation. The infrastructure manager (402) may aggregate this data in a telemetry data map (412) which may be subsequently used to identify resources of any number of information handling systems and/or external resources to satisfy composition, recomposition request and/or decomposition requests.
When the infrastructure manager (402) identifies the resources to be allocated (i.e., resources in an allocatable state), the infrastructure manager (402) may communicate with any number of system control processors (e.g., of control resource sets of information handling systems) to implement the identified allocations. For example, the infrastructure manager (402) may notify a system control processor of a control resource set that portions of a hardware resource set are to be allocated to a compute resource set to instantiate a composed information handling system. The system control processor may then take action (e.g., prepare the portion of the hardware resource set for presentation to a processor of the compute resource set) in response to the notification.
As composed information handling systems are instantiated recomposed and/or decomposed, the infrastructure manager (402) may add information reflecting the resources allocated to composed information handling systems, the workloads being performed by the composed information handling systems, the state of the resources (e.g., allocatable, allocated, cleaning), the health of the resources (e.g., whether the resource is in a compromised state) and/or other types of information to an infrastructure utilization map (414).
The infrastructure utilization map (414) may also specify the ROI and the replacement conditions for each of the resources. The ROI specifies how the resource may be replaced. For example, the ROI may specify that the resource is hot replaceable (e.g., whether the resource can be replaced while the composed information handling systems continues to operate, i.e., without powering down and/or rebooting composed information handling system), that the resource can be replaced upon reboot of the composed information handling system, that the resource can be rebooted and be hot replaceable, or that the resource is neither hot replaceable nor reboot replaceable. The ROI may be specified by the resource manufacturers and/or the users of the IHSs.
The replacement conditions specify when the replacement of the resource may occur. For example, the replacement conditions may specify: (i) that a replacement for a resource may occur when the resource is in a compromised state, or that a replacement of the resource may never occur, and (ii) if a replacement is permitted, and therefore should be performed immediately or upon reboot. The replacement conditions may be generated based on the resources in the composed information handling system, and on the workload that is to be executed on the information handling system. Thus, the replacement conditions for the same resource used in two different composed information handling systems may be different if the workload on the composed information handling systems is different. The replacement conditions may be specified in the composition request, determined automatically by the system control processor manager using heuristics, or obtained from another source.
The infrastructure manager (402) may utilize this information to, for example, decide whether resources should be added to or removed from composed information handling systems as well as to perform the method shown in
In one or more embodiments of the invention, the infrastructure manager (402) is implemented using a hardware resource including circuitry. The hardware resource may be, for example, a digital signal processor, a field programmable gate array, or an application specific integrated circuit. The circuitry may be adapted to cause the hardware resource to perform the functionality of the infrastructure manager (402). The infrastructure manager (402) may be implemented using other types of hardware resources without departing from the invention.
In one or more embodiments of the invention, the infrastructure manager (402) is implemented using a processor adapted to execute computing code stored on a persistent storage that when executed by the processor performs the functionality of the infrastructure manager (402). The processor may be a hardware processor including circuitry such as, for example, a central processing unit or a microcontroller. The processor may be other types of hardware resources for processing digital information without departing from the invention.
When providing its functionality, the infrastructure manager (402) may perform all, or a portion, of the methods illustrated in
In one or more embodiments disclosed herein, the storage (410) is implemented using physical devices that provide data storage services (e.g., storing data and providing copies of previously stored data). The devices that provide data storage services may include hardware resources and/or logical devices. For example, storage (410) may include any quantity and/or combination of memory devices (i.e., volatile storage), long term storage devices (i.e., persistent storage), other types of hardware resources that may provide short term and/or long term data storage services, and/or logical storage devices (e.g., virtual persistent storage/virtual volatile storage).
For example, storage (410) may include a memory device (e.g., a dual in line memory device) in which data is stored and from which copies of previously stored data are provided. In another example, storage (410) may include a persistent storage device (e.g., a solid-state disk drive) in which data is stored and from which copies of previously stored data is provided. In a still further example, storage (410) may include (i) a memory device (e.g., a dual in line memory device) in which data is stored and from which copies of previously stored data are provided and (ii) a persistent storage device that stores a copy of the data stored in the memory device (e.g., to provide a copy of the data in the event that power loss or other issues with the memory device that may impact its ability to maintain the copy of the data cause the memory device to lose the data).
The storage (410) may also be implemented using logical storage. A logical storage (e.g., virtual disk) may be implemented using one or more physical storage devices whose storage resources (all, or a portion) are allocated for use using a software layer. Thus, a logical storage may include both physical storage devices and an entity executing on a processor or other hardware resource that allocates the storage resources of the physical storage devices.
The storage (410) may store data structures including, for example, the telemetry data map (412) and the infrastructure utilization map (414). These data structures may be maintained by, for example, the infrastructure manager (402). For example, the infrastructure manager (402) may add, remove, and/or modify information included in these data structures to cause the information included in these data structure to reflect the state of any number of information handling systems, external resources, and/or composed information handling systems.
While the storage (410) has been illustrated and described as including a limited number and type of data, a storage in accordance with embodiments of the invention may store additional, less, and/or different data without departing from the invention.
While the system control processor manager (50) has been illustrated and described as including a limited number of specific components, a system control processor manager in accordance with embodiments of the invention may include additional, fewer, and/or different components than those illustrated in

In step 500, a composition request for a composed information handling system is obtained. The composition request may be obtained using any method without departing from the invention. For example, the composition request may be obtained as part of a message from another entity operably connected to a system control processor manager. In another example, the composition request may be locally stored in a storage of a system control processor manager.
The composition request may be a data structure specifying that the composed information handling system is to be instantiated. As discussed with respect to
In one or more embodiments of the invention, the composition request includes a list of resources to be allocated to the composed information handling system. For example, the composition request may specify resources, memory resources, storage resources, graphics processing resources, compute acceleration resources, communications resources, etc. The list may include any type and quantity of resources.
In one or more embodiments of the invention, the composition request specifies how the resources are to be presented. For example, the composition request may specify virtualization, emulation, etc. for presenting the resources.
In one or more embodiments of the invention, the composition request specifies how the resources used to present the resources are to be managed (e.g., a management model such as data integrity, security, management, usability, performance, etc.). For example, the composition request may specify levels of redundancy for data storage, data integrity to be employed (e.g., redundant array of independent disks (RAID), error correction code (ECC), etc.), levels of security to be employed for resources (e.g., encryption), and/or other information that specifies how system control processors are to utilize resources for presentation of resources to composed information handling systems. The methods employed by the system control processors may be transparent to the composed information handling systems because the resources may be presented to the compute resource sets of the composed information handling systems as bare metal resources while the system control processors provide the management functionality.
In one or more embodiments of the invention, the composition request includes a list of applications to be hosted by the composed information handling system. The list may include any type and quantity of applications.
The composition request may also specify the identities of one or more system control processors hosted by other devices. In some scenarios, as noted above, resources from other information handling systems may be used to form a composed information handling system. The identifiers of the system control processors of these other information handling systems may be used to form operable connections between the system control processors. These connections may be used by the system control processors to present, as bare metal resources, resources from other information handling systems to compute resource set(s) of the composed information handling system.
For example, a system control processor of a first information handling system may manage a storage device as a virtualized resource. The system control processor may connect to a second system control processor which, in turn, is operably connected to a compute resource set. The second control processor may operate as a pass through for the system control processor while presenting the virtualized resource as a bare metal resource to the compute resource set. Consequently, when the compute resource set attempts to communicate with the storage, the compute resource set may send a bare metal communication to the system control processor, the system control processor may relay the bare metal communication to the second system control processor, and the second system control processor may processes the bare metal communication in accordance with its virtualization model (e.g., converting a logical block address to a physical block address in accordance with the virtualization model) to instruct the storage device to perform one or more actions to satisfy the bare metal communication.
In one or more embodiments of the invention, the composition request specifies a desired outcome. The desired outcome may be, for example, computer implemented services to be provided in response to the composition request. In another example, the desired outcome may be a list of applications to be hosted in response to the composition request. In other words, the composition request may specify a desired outcome without specifying the resources that are to be used to satisfy the requests, the methods of managing the resources, models employed to provide for data integrity/security/etc. Such a composition request may be referred to as an intent based composition request.
In step 502, at least one compute resource set having resources specified by the composition request is identified. The at least one compute resource set may be identified by matching the resources specified by the composition request to at least one compute resource set having those resources using a telemetry data map (412,
For example, the telemetry data map (412,
If no compute resource set includes all of the resources specified by the composition request, multiple compute resource sets having sufficient hardware resources to meet the resources specified by the composition request may be identified as the at least one compute resource set.
However, the at least one compute resource set may not able to satisfy all of the resources specified by the composition request. As discussed above, compute resource sets may only include a limited number and type of hardware resources. Consequently, the at least one compute resource set may not be able to provide some of the resources (e.g., graphics processing, communications, etc.) specified by the composition request.
In step 504, at least one hardware resource set having hardware resources specified by the composition request is identified. The at least one hardware resource set may be identified similarly to that described with respect to the identified of the at least one compute resource set of step 502. For example, the resources requirements specified by the composition request may be matched to compute resource sets.
In step 506, management services for the at least one compute resource set and the at least one hardware resource set are setup using at least one control resource set. The management services may include, for example, virtualization, emulation, abstraction, indirection, and/or other type of services to meet the requirements of data integrity, security, and/or management models.
The management services may also include monitoring of the utilization of the hardware resources of the at least one compute resource set and the at least one hardware resource set. For example, the utilization monitor hosted by the system control processor of the at least one control resource set may be configured to perform the monitoring of the hardware resources of these sets. Consequently, the system may begin to monitor the use of these hardware resources by a client sent the composition request.
As discussed above, the utilization manager may be monitoring by communicating with the hardware resources of the at least one compute resource set via sideband communication, intercept communications from the at least one computing resource set directed toward the at least one hardware resource set to identify how the hardware resources of the at least compute resource set are using the hardware resources of the at least one hardware resource set, etc. Consequently, the monitored computing resource use may be transparent to entities executing using the at least one compute resource set.
The management services may be setup, in all or in part, via the method illustrated in
In step 508, the managed at least one hardware resources are presented to the managed at least one compute resource set as bare metal resources using the at least one control resource set to instantiate the composed information handling system to service the composition request.
To present the managed at least one hardware resource set, the system control processor manager may instruct the system control processors of the at least control resource set to present the managed at least one hardware resource set as discoverable bare metal resources to the at least one compute resource set. For example, the at least one control resource set may send a bare metal communication to one or more processors of the managed at least one compute resource set to cause the processors to discover the presence of the presented bare metal resources. By doing so, the processors may then begin to utilize the managed at least one hardware resource set as bare metal resources resulting in a composed information handling system having all of the resources necessary to provide desired computer implemented services.
The method may end following step 508.
Using the method illustrated in
Turning to
While
In step 510, resource management services for the at least one compute resource set and the at least one hardware resource set are setup.
To setup the resource management services, the system control processor manager may cooperate with the at least one control resource set. For example, the system control processor manager may generate instructions for implementing the management services, encapsulate the instructions in a message, and send the message to one or more system control processors of the at least one control resource set. In response to receiving the message, the system control processors may implement the instructions thereby implementing any number of management services such as virtualization, emulation, etc.
The system control processor manager may also include identification information for the system control processors that will cooperate in presenting resources as part of instantiating a composed information handling system. Consequently, the system control processors of control resource sets that will facilitate bare metal presentation of resources to processors of compute resource sets of the composed information handling system may be able to identify each other, communicate with one another, etc.
Setting up management services for the hardware resource set may include, for example, preparing translation, indirection, or abstraction tables used to translate logical addresses provided by compute resource sets to physical addresses utilized by hardware resources of the hardware resource set.
In another example, setting up management services may include, if the type of the resource allocation is a portion of a virtualized resource, making a call to a virtualization resources manager to allocate the portion of resources from an existing virtualized resource or by instantiating a new virtualized resource and allocating the portion from the new virtualized resource.
In a still further example, if the type of the resource allocation requires an emulated resource, providing management services may include instantiating a corresponding emulation layer between a hardware resource of the hardware resource set and the compute resource set. Consequently, bare metal communications between the compute resource set and the hardware resource used to present the bare metal resource to the compute resource set may be automatically translated by the system control processor.
Setting up management services may further include modifying the operation of one or more devices to provide, for example, data integrity functionality (e.g., RAID, ECC, etc.), security functionality (e.g., encryption), and/or other functionalities that are transparent to the composed information handling system.
By setting up management services, a managed at least one compute resource set and a managed at least one hardware resource set may be obtained.
In step 512, a utilization monitor that monitors utilization of the at least one compute resource set and the at least one hardware resource set is instantiated.
The utilization monitor may be instantiated by beginning execution of a utilization monitor on a system control processor of the at least one control resource set that manages presentation of the at least one hardware resource set to the at least one control resource set. The utilization monitor may then be configured (e.g., provided an identifier of the composed information handling system and components thereof that will be monitored by it) to monitor the use of resources of the composed information handling system, performance of applications by the composed information handling systems, and/or to otherwise obtain quality metric usable to determine whether the computer implemented services provided by the composed information handling system meets client expectations. If a utilization monitor is already executing on the system control processor, the existing instance of the utilization monitor may be configured to monitor the use of resources, application performance, etc. of the composed information handling system.
For example, the system control processor manager may generate instructions for beginning execution and/or configuration of the utilization monitor, encapsulate the instructions in a message, and send the message the system control processor. In response to receiving the message, the system control processor may implement the instructions thereby instantiating the utilization monitor and beginning monitoring of the use of the resources of the composed information handling system.
The method may end following step 512.
Using the method illustrated in
While
In step 600, composed information handling systems for a deployment are instantiated using information handling systems. The deployment may provide any number, and type, of functionalities and may include any number of composed information handling systems.
In one or more embodiments of the invention, the deployment provides computer implemented services using virtual machines. Consequently, the composed information handling systems of the deployment may host a hypervisor and other applications for supporting the operation of the virtual machines. The virtual machines may host any number, and types, of applications that provide computer implemented services desired by a client.
In one or more embodiments of the invention, the composed information handling systems are instantiated by invoking the functionality of an infrastructure manager by sending one or more composition requests; as described with respect to
The deployment may be instantiated at the request of a client or another entity.
In step 602, operation information is obtained from one or more system control processors that are used to implement the deployment.
The operation information may be obtained from utilization monitors, hosted by system control processors of the composed information handling systems, of the deployment. For example, the utilization monitors may monitor workloads being performed by the composed information handling systems as well as the health of the resources, and report to the system control processor manager,
The health of the resources may be monitored by intercepting bare metal communications between the hardware devices of a control resource set and the hardware devices of a hardware resource set. The bare metal communications may be analyzed to ascertain whether requests by devices of either set are being serviced by the corresponding devices of the other set. The aforementioned information may be used to infer whether any of the hardware devices of the compute resource set or hardware resource set are compromised.
The health of the resources may be monitored by invoking the health reporting functionality of the hardware devices of the compute resource set and/or hardware resource set. For example, a system control processor may send appropriate requests to any of these hardware devices. The hardware devices may provide, in response to the requests, health information, diagnostic reports, and/or other types of information that may be used to ascertain the state of the hardware devices.
When obtaining the health information, control plane entities may be unaware of the information collection. As noted above, system control processors may present computing devices from abstracted hardware devices as bare metal resources. Consequently, the entities present in the control plane may be unaware of the operation of the system control processor in so much as its health information collection activities.
In step 604, it is determined whether the monitoring indicates a compromised state of a device. The monitoring may indicate a compromised state when it indicates that it is likely that the device will be unlikely to provide resources to a composed information handling system, entirely or in part, in the future (or currently). For example, when a health reporting function is invoked, a report regarding the operational expectancy of the device may be provided. The report may indicate whether the device is likely to or is already in a compromised state.
If it is determined that the monitoring indicates that the device is in a compromised state, then the method may proceed to step 604. If the monitoring does not indicate that a device is in a compromised state, then the method may end following step 602.
In step 606, the system control processor manager performs a hardware resource replacement operation to attempt to automatically heal the resource that is in the compromised state. See
While
In step 700, replacement option information (ROI) for the resource is obtained, e.g., from the infrastructure utilization map.
In step 702, replacement conditions (RC) for the resource are obtained, e.g., from the infrastructure utilization map.
In step 704, a determination is made about whether the resource may be replaced immediately (i.e., without requiring a reboot). The resource may be replaced immediately if the ROI indicates that the resource is hot replaceable and the RC specifies: (a) that replacement may occur when the resource is in a compromised state and (b) that replacement may occur immediately. If the resource may be replaced immediately, the process proceeds to step 706; otherwise, the process proceeds to step 708.
In step 706, the system control processor identifies a replacement resource that may be allocated to the composed information handling system and then proceeds to remove the resource from the composed information handling system, and allocates the replacement resource to the composed information handling system. The allocation of the replacement resource to the composed information handling system is as described above, e.g., in
In step 708, when the resource may not be immediately replaced, a determination is made about whether the resource may be replaced during the next reboot of the composed information handling system. The resource may be replaced at the next reboot if the ROI indicates that the resource is hot replaceable and/or reboot replaceable and the RC specifies: (a) that replacement may occur when the resource is in a compromised state and (b) that replacement may occur during reboot. If the resource may be replaced at reboot, the process proceeds to step 710; otherwise, the process ends.
The resource may not be replaced: (a) when the ROI indicates that the resource is neither hot replaceable nor reboot replaceable, or (b) when the RC indicates that the resource is never to be replaced.
In step 710, the system control processor waits until the composed information handling system reboots and then identifies a replacement resource that may be allocated to the composed information handling system, and then proceeds to remove the resource from the composed information handling system, and allocates the replacement resource to the composed information handling system. The allocation of the replacement resource to the composed information handling system is as described above, e.g., in
As discussed above, embodiments of the invention may be implemented using computing devices.
In one embodiment of the invention, the computer processor(s) (802) may be an integrated circuit for processing instructions. For example, the computer processor(s) may be one or more cores or micro-cores of a processor. The computing device (800) may also include one or more input devices (810), such as a touchscreen, keyboard, mouse, microphone, touchpad, electronic pen, or any other type of input device. Further, the communication interface (812) may include an integrated circuit for connecting the computing device (800) to a network (not shown) (e.g., a local area network (LAN), a wide area network (WAN) such as the Internet, mobile network, or any other type of network) and/or to another device, such as another computing device.
In one embodiment of the invention, the computing device (800) may include one or more output devices (808), such as a screen (e.g., a liquid crystal display (LCD), a plasma display, touchscreen, cathode ray tube (CRT) monitor, projector, or other display device), a printer, external storage, or any other output device. One or more of the output devices may be the same or different from the input device(s). The input and output device(s) may be locally or remotely connected to the computer processor(s) (802), non-persistent storage (804), and persistent storage (806). Many different types of computing devices exist, and the aforementioned input and output device(s) may take other forms.
One or more embodiments of the invention, enable the composed information handling systems to be automatically healed using a combination of ROIs and RCs. In this manner, users can specify the ROI and the RCs, and then the system control processor manager (or another management entity) can monitor the composed information handling systems, and automatically take steps to replace resources that are determined to be in a compromised state without user intervention. However, by specifying the ROIs and RCs, the user may exert granular control on how the automatic healing is to be performed for resources in particular composed information handling systems. In this manner, the users are still able to control how the healing is to occur, without having to manually perform such healing. As a result, there is less overhead required to manage the composed information handling systems, and less downtime as the composed information handling systems may be automatically healed.
