In general, embodiments of the invention relate to systems, devices, and methods for providing computer implemented services and data protection services using composed information handling systems. To provide computer implemented services, computing resources may need to be allocated for the performance of the services. The services may include, for example, processing resources, memory, resources, storage resources, computing resources, etc.
To allocate the computing 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 computing resources. Computing resources from multiple information handling systems may be allocated to a composed information handling system thereby enabling a composed information handling system to utilize computing resources from any number of information handling system for performance of corresponding computer implemented services.
To allocate computing resources, the system may include a system control processor manager. The system control processor manager may obtain composition requests. The composition requests may indicate a desired outcome such as, for example, execution of one or more application, providing of our or more services, etc. The system control processor manager may translate the composition requests into corresponding quantities of computing resources necessary to be allocated to satisfy the intent of the composition requests.
Once the quantities of computing resources are obtained, the system control processor manager may allocate resources of the information handling system to meet the identified quantities of computing resources by instructing system control processors of the information handling systems to prepare to present hardware resources sets of the information handling system to compute resource sets of the information handling systems.
Additionally, during the preparation of the hardware resource sets, the system control processor manager may instruct the system control processors to manage the hardware resources of the hardware resource sets and perform data protection services. The system control processors may identify and prepare trace volumes to be used as part of providing data protection services. However, when the system control processors present aforementioned resources to the compute resource sets, the system control processors may present the resources as bare metal resources while managing them in more complex manners. The system control processors may exclude the trace volume from presentation to the compute resource sets, thereby rendering the trace volume transparent to the compute resource sets and the entities executing on the compute resource sets.
By doing so, embodiments of the invention may provide data protection services using system control processors and the trace volumes without interrupting and/or hindering the performance of computer implemented services provided by the compute resource set and entities executing on the compute resource set. Consequently, even though the resulting composed information handling system control plane may be unaware of the implementation of the data protection services provided by the system control processors and the trace volume, the composed information handling systems may still operate in accordance with data protection services, thereby providing a unified method of managing the data protection services for composed information handling systems.
Data protection services may include generating full backups, snapshots, incremental backups, differential backups and other and/or additional types of backups, performing replication services, restoration services, any point in time protection services (e.g., by copying all the data in the trace volume) and other and/or additional data protection services that require access to the data and changes of the data generated in the life cycle of an application without departing from the invention. The unified method therefore allows for multiple and a multitude of the data protection services to happen in sequence or in parallel transparently to the system above and using the same trace volume, resulting in no additional overhead in performance of application write data paths.
The information handling system of the system of
To provide computer implemented services, the information handling systems (60) may utilize computing resources provided by hardware devices. The computing 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 devices. Various hardware devices may provide these computing resources.
Performing the computer implemented services may result in the generation of data. The data may be may be important to the system and/or a user or the system and may be required to be stored for protection and/or restoration purposes. The data may be stored for other and/or additional purposes without departing from the invention. Storing the data in the hardware devices of the system may be problematic because hardware devices may fail. The failure of hardware device may result in data loss and/or data corruption.
In general, embodiments of the invention relate to system, methods, and devices for managing the hardware resources of the information handling systems (22) and/or other resources (e.g., external resources (30)) to provide data protection services for data generated by the system. The hardware resources of the information handling systems (22) may be managed by instantiating one or more composed information handling systems using the hardware resources of the information handling systems (22), external resources (30), and/or other types of hardware devices operably connected to the information handling systems (22). During the instantiation of the composed information handling systems, one or more devices, including a system control processor and a trace volume, may be automatically setup to perform data protection services for the composed information handling system, including the generation of backups of data, further protecting data stored in the composed information handling systems. Consequently, data protection services may be provided to the composed information handling systems in an efficient and unified manner, resulting in the increased protection of data generated through the performance of computer implemented services by the composed information handling systems.
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 and (ii) aggregating computing 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. By doing so, instantiated composed information handling systems may provide computer implemented services in accordance with the composition requests.
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 computing 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 computing resources of an information handling system into these resource sets, different quantities an types of computing resource 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 computing 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 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 computing resources of the information handling systems (60), the external resources (30), and/or other types of hardware devices operably connected to the information handling systems (60). The composed information handling system may utilize the computing 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 computing resources assigned to the composed information handling system. The applications may provide the computer implemented services.
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 computing resources of an information handling system, may perform actions on behalf of the system control processor manager (50) to aggregate computing resources together, may organize the performance of duplicative workloads to improve the likelihood that workloads are completed, 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, data protection, 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. For additional details regarding the information handling systems (60), refer to
The external resources (30) may be provide computing resources that may be allocated for use by composed information handling systems. For example, the external resources (30) may include hardware devices that provide any number and type of computing resources. The composed information handling system may use these resource to provide their functionalities. Different external resources (e.g., 32, 34) may provide similar or different computing resources.
In one or more embodiments of the invention, the system of
The system of
The system control processor manager (50), information handling systems (60), backup storages (70), 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), backup storages (70), and/or external resources (30) described in this application and/or all, or a portion, of the methods illustrated in
While the information handling systems (60) have 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
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 devices 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 devices 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 and manage data protection services using a trace volume. 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 computing resources. By doing so, a composed information handling system may be instantiated. Additionally, the control resource set (108) may prepare hardware resource sets (e.g., 110) or other computer resources (e.g., system control processors (114)) to be a trace volume and perform data protection services.
The control resource set (108) may not present the trace volume to the processors (106) of the compute resource set (102) to establish transparency. In other words, the trace volume may be used to provide data protection services without the knowledge of the processors (106) or any entity executing on the processors (106) of the compute resource set (102).
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 compute 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 compute 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.
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 computing 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 system control processors (114) of the hardware resource set (110) may present computing 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 managing presentation of other types of resources to the compute resource set (102).
By presenting the computing 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 computing 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 devices providing the computing 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 manage 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 computing resources presented through one or more layers of indirection, abstraction, virtualization, etc. In other words, an indirect user of hardware devices and computing resources provided thereby.
In one or more embodiments of the invention, data plane entities directly utilize computing resources. For example, data plane entities may instruct hardware devices on their operation thereby directly utilizing computing resources provided thereby. Data plane entities may present the computing 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 computing 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 devices that provide computing 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 (120).
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 (120).
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 devices including circuitry adapted to provide the functionality of the compute resources interface (112).
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 (TO) 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 devices including circuitry adapted to provide the functionality of the hardware resources interface (116).
In some embodiments of the invention, the compute resource set (120), 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 devices 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-ban 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 devices that may provide any quantity and type of computing 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 system control processors or other entities may duplicate writes of data to the storage devices (200). In other words, the storage devices (200) may be used to store a first copy of data and trace volumes (discussed below) may be used to store the second, duplicated copy of data. 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 storages 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 enterprise 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 computing 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 computing 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, etc. The special purpose devices (204) may include other types of devices for providing other types of computing resources without departing from the invention.
The system control processors of the information handling systems may mediate presentation of the computing 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 computing 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 devices in accordance with one or more models including data protection models. The models may include other models such as, for example, security models, workload performance availability models, reporting models, etc. The data protection models may include performing data protection services for data generated by the composed information handling system.
In one or more embodiments of the invention, the data protection services include duplicating writes of data directed toward the logical hardware resources (118) to trace volumes (discussed below). The system control processors may obtain bare metal communications from computing resources indicating writes of data. In response to obtaining the bare metal communications, the system control processors may write first copies to the logical hardware resources as specified by the bare metal communications, and may also write second copies of data to the trace volume. The data protection services may also include generating backups using the trace volume. The data protection services may include other types of data protection services such as deduplication, erasure coding, compression, and other and/or additional data protection services without departing from the invention.
To perform the aforementioned data protection services, during the instantiation of a composed information handling system, the system control processor manager may prepare one or more system control processors and the trace volume to be used to provide the data protection services. The system control processor manager may instruct the one or more system control processors to perform duplicative writes and backup generations of data using the trace volume.
The manner of operation of these devices i.e., the performance of the aforementioned data protection services, may be transparent to the computing resource sets utilizing these hardware devices 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 data protection services for composed information handling systems.
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 and operation of composed information handling systems. By doing so, a system that includes information handling systems may dynamically instantiate composed information handling systems to provide computer implemented services and to provide data protection services to the composed information handling system.
To instantiate and operate composed information handling systems, the system control processor (298) may include a composition manager (300), a physical resources manager (302), an emulated resources manager (304), a virtual resources manager (306), a data protection orchestrator (320), an system control processor 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 and operating 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 computing 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 devices (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 computing 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, data protection 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).
Additionally, the system control processors may take into account an importance of completion of workloads when preparing and presenting resources. For example, some workloads that may be performed by various hardware devices may be critical (e.g., high availability workloads) to the computer implemented services to be provided by a composed information handling system. In such a scenario, the system control processor may over allocate resources (e.g., beyond that requested by a compute resource set) for performance of the workloads so that at least two instances of the workloads can be performed using duplicative resources. By doing so, it may be more likely that at least one of the workloads will be completed successfully. Consequently, the system control processor may provide the output of one of the workloads to compute resource sets of a composed information handling system.
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) 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 devices used by the system control processor (298) to present the bare metal resources to the compute resource set(s). In turn, the hardware devices 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 devices to present a quantity and/or type of resources to a compute resource set as specified by a composition requests (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 system 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.
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 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 command and the resources available to service these bare metal commands/communications.
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 devices of a compute resource set may be compatible with different types of hardware devices. Consequently, resources allocated to provide bare metal resources may not necessarily be compatible with the hardware devices 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.
To provide the aforementioned data protection services, the system control processor (298) may include the data protection orchestrator (320). The data protection orchestrator may include the functionality to perform the data protection services. The data protection services may include (i) identifying hardware resources to be used as trace volumes, performing duplicative writes to hardware resources and the trace volume, generating backups of data using the trace volume, and providing backups to the backup storages (e.g., 70,
The functionalities of the physical resources manager (302), emulated resources manager (304), virtual resources manager (306), and the data protection orchestrator (320) may be utilized in isolation and/or combination to provide bare metal resources to compute resource sets and to provide management services to the composed information handling system. 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 TO from compute resource sets to hardware devices), 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), virtual resources manager (306), and the data orchestration manager (320) may be invoked using any communication model including, for example, message passing, state sharing, memory sharing, etc.
The system control processor manager (308) may manage the general operation of the system control processor (298). For example, the system control processor 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), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), and the data protection orchestrator (320) and/or other entities hosted by the system control processor (298) may call or otherwise utilize the system control processor 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, 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 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, the composition manager (300), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), data protection orchestrator (320), system control processor manager (308), and/or hardware resource services (310) are implemented using a hardware device including circuitry. The hardware device 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 device to perform the functionality of the composition manager (300), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), data protection orchestrator (320), system control processor manager (308), and/or hardware resource services (310). The composition manager (300), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), data protection orchestrator (320), system control processor manager (308), and/or hardware resource services (310) may be implemented using other types of hardware devices without departing from the invention.
In one or more embodiments of the invention, the composition manager (300), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), data protection orchestrator (320), system control processor 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), physical resources manager (302), emulated resources manager (304), virtual resources manager (306), data protection orchestrator (320), system control processor 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 devices 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 devices (e.g., processors, digital signal processors, field programmable gate arrays, application specific integrated circuits, etc.) that provide the function. The hardware devices may be programmed to do so by, for example, being able to execute computer instructions (e.g., computer code) that cause the hardware devices to provide the function. In another example, the hardware device 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 devices. Computer instructions may be used to program a hardware device 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 devices 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 devices 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 device 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 trace volume (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 devices, virtualized devices, etc.) available for allocation 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 trace volume (318) may be implemented using one or more data structures that includes data generated by and/or obtained from the compute resource set of the composed information handling system. The data written to the trace volume (318) may be written as part of a duplicative write. In other words, a first copy of data may be written to a storage resource of the hardware resource set and a second copy of data may be written to the trace volume (318). The trace volume (318) may include a limited size and may only include a limited amount of data. The trace volume (318) may be managed by, for example, the data protection orchestrator (320). The trace volume (318) may be transparent to the compute resource set (e.g., 102,
The trace volume (318) may be implemented by the data protection orchestrator (320) as a cyclical buffer. The trace volume (318) may be implemented as if one end of the trace volume (318) is connected to the other end in a circular fashion. The data protection orchestrator (320) may write data to the trace volume starting at a first end and moving to the other end of the trace volume (318) in a sequential manner. When the data protection orchestrator (320) has reached the other end of the trace volume (318) and the trace volume (318) is full, the data protection orchestrator (320) may overwrite the data at the first end of the trace volume (318). The data protection orchestrator (320) may implement the trace volume (318) with a first in, first out (FIFO) queue. In other words, the data protection orchestrator (320) may delete and/or overwrite data written to the trace volume (318) at a later point in time before deleting and/or overwriting data written to the trace volume (318) at a more recent point in time. The data protection orchestrator (320) may use the trace volume (318) to generate backups of the data included in the trace volume (318). The trace volume (318) may be used for other and/or additional purposes without departing from the invention.
Additionally, data written to the trace volume (318) may also include metadata indicating the storage location of the data in the target volume. For example, if a one megabyte write of data is intended for a particular offset block in the target volume, the trace volume (318) may include the data and metadata specifying that the write is intended for the particular offset block. The metadata may be used to reconstruct the target volume correctly. The metadata and data may be written to the trace volume (318) in an intertwined manner or separately. In other words data and metadata may be written in sequence in aligned blocks, or there may be a separate stream of metadata entries stored in different aligned blocks that may specify the storage locations of the target volume associated with the data. The metadata and data chunks may also be numbered or include identifiers in order to differentiate the data and metadata included in the trace volume (318) from other data and metadata included in the trace volume (318). The metadata included in the trace volume (318) may include other and/or additional information associated with the data stored in the trace volume (318) without departing from the invention. In addition, the trace volume (318) may also include an indicator to where in the trace volume (318) the head of the trace volume (318) is currently writing to. This may allow users of the trace volume (318) (i.e., system control processors) to know the current position of the trace volume (318). System control processor and/or other entities using the trace volume (318) may store (not on the trace volume (318)) the location of their previous reads from the trace volume (318), and therefore derive that they need only to read from the previous location to the current head in subsequent reads. In other words, periodic and/or sporadic access to the trace volume (318) may be efficient as only the write changes since the last time may be written to the trace volume (318).
Furthermore, any number of data protection operations may be concurrently performed using the trace volume (318), as each may include its own previous location of the trace volume (318) used stored separately, and read operations from the trace volume (318) may always happen in parallel to each other and to trace write operations without disrupting each other. If the metadata of the read and write operations of the trace volume (318) is numbered or includes identifiers, and there is knowledge of the position of the head of the trace volume (318), then the identifier of the oldest location in the trace volume (318) may be the one just after the head as the trace volume is a cyclic buffer. Data protection operations may check if their previous location is between the oldest location and the head of the trace volume (318). If it is not, (i.e., the previous location may typically be less than the oldest) it may mean that the trace volume (318) has rolled over before a successful backup or data protection operation has taken place, and a full backup of the original target volume may be taken as the trace volume (318) may include missing data.
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 computing 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. 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 requests for composed information handling systems, determining the resources to allocate to instantiate composed information handling systems, 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 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 computing resources. For example, the infrastructure manager (402) may utilize an outcome based computing resource requirements lookup table (414) to match an expressed intent to resources to be allocated to satisfy that intent. The outcome based computing resource requirements lookup table (414) may specify the type, quantity, method of management, and/or other information regarding any number of computing 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 cooperate with the system control processors, the infrastructure manager (402) may obtain telemetry data regarding the computing 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 requests (e.g., instantiate one or more composed information handling systems to meet the requirements of the composition requests).
When the infrastructure manager (402) identifies the computing resources to be allocated, the infrastructure manager (402) may communicate with any number of system control processors 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, 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, and/or other types of information to a composed infrastructure map (416). The infrastructure manager (402) may utilize this information to, for example, decide whether computing resources should be added to or removed from composed information handling system. Consequently, computing resources may be dynamically re-provisioned over time to meet changing workloads imposed on composed information handling systems.
In one or more embodiments of the invention, the infrastructure manager (402) is implemented using a hardware device including circuitry. The hardware device 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 device to perform the functionality of the infrastructure manager (402). The infrastructure manager (402 may be implemented using other types of hardware devices 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 devices 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 devices 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 devices 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 device 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), outcome based computing resource requirements lookup table (414) and the composed infrastructure map (416). 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.
Any of these data structures may be implemented using, for example, lists, tables, unstructured data, databases, etc. While illustrated in
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
As discussed above, the system of
While
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 computing resources to be allocated to the composed information handling system. For example, the composition request may specify computing resources, memory resources, storage resources, graphics processing resources, compute acceleration resources, communications resources, etc. The list may include any type and quantity of computing resources. The list of computing resources may include computing resources to be used to provide data protection services. The list of computing resources may specify one or more storage resources to be used as a trace volume and one or more computing resources to perform backup generations using the trace volume.
In one or more embodiments of the invention, the composition request specifies how the computing resources are to be presented. For example, the composition request may specify virtualization, emulation, etc. for presenting the computing resources.
In one or more embodiments of the invention, the composition request specifies how the resources used to present the computing 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 composition request may specify that data protection services are to be provided to the computing resources of the composed information handling system. The data protection services may include performing duplicative writes and backing up data using a trace volume. 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, computing resources from other information handling systems to compute resource set(s) of the composed information handling system.
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 protection/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 computing resources specified by the composition request is identified. The at least one compute resource set may be identified by matching the computing 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 computing resources specified by the composition request, multiple compute resource sets having sufficient hardware devices to meet the computing resources specified by the composition request may be identified as the at least one compute resource set.
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 computing resources requirements specified by the composition request may be matched to compute resource sets.
In step 506, management services for the hardware resources are setup using at least one control resource set to obtain logical hardware resources managed by the at least one control resource set. The management services may include, for example, virtualization, emulation, abstraction, indirection, duplicative writes, backup generation, and/or other type of services to meet the requirements of data integrity, security, and/or management models. The control resource set may provide management services to the at least one hardware resource set identified in step 506.
The management services may be setup for the hardware resource set using the at least one control resource set to obtain logical hardware resources via the method of
In step 508, the logical hardware resources are presented to the 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 logical hardware resources, the system control processor manager may instruct the system control processors of the at least control resource set to make the bare metal resources discoverable. For example, the at least one control resource set may send a bare metal communication to one or more processors of the 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 logical hardware resources 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 510.

In step 520, at least one storage resource is identified to be used as a trace volume during the performance of management services. The at least one storage resource may be identified by matching one or more of the hardware resources specified by the composition request to at least one storage resource using a telemetry data map (412,
For example, the telemetry data map (412,
In one or more embodiments of the invention, the at least one storage resource is identified to be used as the trace volume during the performance of management services based on the trace volume characteristics included in the composition request. The composition request may include trace volume characteristics that may be matched with the characteristics of the at least one storage resource to identify the at least one storage resource to be used as the trace volume. The trace volume characteristics may include information and/or requirements regarding the to be instantiated trace volume. For example, the trace volume characteristic may specify a data storage size of the desired trace volume. The telemetry data map (412,
If no hardware resources includes all of the trace volume characteristics specified by the composition request, multiple hardware resources having sufficient hardware devices to meet the trace volume characteristics specified by the composition request may be identified as the at least one storage resource to be used as the trace volume.
In one or more embodiment of the invention, the at least one storage resource includes hardware resources of the at least one hardware resource set. The at least one storage resource may include any number of hardware resources (e.g., solid state disk drives) of the at least one hardware resource set. The at least one storage resource may include other and/or additional hardware resources from other and/or additional components of the system illustrated in
In one or more embodiments of the invention, the at least one storage resource includes hardware resources not included in any of the hardware resource sets. For example, the hardware resources may be, for example, one or more storage devices of the system control processor(s) of the control resource set. The storage devices may be, for example, solid state disk drives of the system control processor(s) of the control resource set. The at least one storage resource may include other and/or additional hardware resources from other and/or additional components of the system illustrated in
In step 522, the hardware resource set and the control resource set are prepared to implement the management services using the trace volume to obtain logical hardware resources. To setup the 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 duplicative writes, backup generation, 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 devices of the hardware resource set including the trace volume.
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 device of the hardware resource set and the compute resource set. Consequently, bare metal communications between the compute resource set and the hardware device 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 data protection functionality. Other functionalities may include, 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.
The method may end following step 522.
Using the method illustrated in
Turning to
While
Prior to step 530, a composed information handling system, including a system control processor, was instantiated based on a composition request via the methods of
In step 530, a bare metal communication indicating a write of data is obtained. A compute resource of the compute resource set of the composed information handling system may send a message to the storage control processor. The message may include a bare metal communication. The bare metal communication may indicate that data is to be written to and stored in one or more hardware resources of the hardware resource set. The bare metal communication may also specify a storage resource of the hardware resource set of the composed information handling system in which to write and store the data. The message may also include the data that is to be written to and stored in one or more hardware resources of the hardware resource set and metadata associated with the data.
In step 532, a first copy of data is written in a storage resource of the hardware resource set. In response to obtaining the bare metal communication, the system control processor may generate two copies of the data specified in the bare metal communication, a first copy of the data and a second copy of the data. The system control processor may write the first copy of the data to the storage resource specified in the bare metal communication. The system control processor may use and/or invoke the functionality of the physical resources manager, emulated resources manager, and/or the virtual resources manager to write the first copy of data to the storage resource. The system control processor may use address tables and/or other resources generated using the physical resources manager, emulated resources manager, and/or the virtual resources manager to write the first copy of data to the storage resource. As a result, the first copy of data may be stored in the storage resource of the hardware resource set of the composed information handling system.
In step 534, a second copy of the data is written in a trace volume. The system control processor may write and store the second copy of data to the trace volume similarly to the methods discussed above in step 532 without departing from the invention. As a result, the second copy of data may be stored in the trace volume of the composed information handling system. The second copy of data may include changed portions of the data that were modified since a previous point in time. The trace volume may include previously written data not associated with the second copy of data without departing from the invention.
In various embodiments of the invention, the methods of steps 532 and 534 may be performed by other components such as a compute resource of the at least one compute resource set during the performance of other management services for application data generated by applications executing on the at least one compute resource set (e.g., implementing RAID, ECC, etc.) without departing from the invention. The bare metal communication of step 530 may indicate that the data has been written to the storage resource and the trace volume. Based on obtaining the bare metal communication, the system control processor may perform the data protection services of step 536 using the trace volume.
In step 536, a backup is generated using the second copy of the data stored in the trace volume. The system control processor may monitor the trace volume and identify a backup trigger event. The backup trigger event may be that a protection policy obtained from the system control processor manager or another component indicates that a backup of the trace volume is to be generated. A protection policy may be a data structure that includes events and/or conditions which, when identified by the system control processor, indicate that a backup using the trace volume is to be generated. The protection policy may specify (i) a period of time elapsing after which a backup using the trace volume is to be generated, (ii) a point in time to generate a backup using the trace volume, (iii) the occurrence of a condition precedent such as modification of the resources of the composed information handling system of which a backup using the trace volume is to be generated, and (iv) any other event and/or condition that may result in the generation of a backup using the trace volume without departing from the invention. The backup trigger event may include other events identified by the system control processor (e.g., obtaining a backup generation request from another component of the system of
In one or more embodiments of the invention, the size of the second copy of data is greater than the size of the trace volume or the available space of the trace volume. In such embodiments of the invention, the system control processor may write a first portion of the second copy of data that may be stored in the trace volume to the trace volume in step 534, and generate a backup of the portion of second copy of data via the methods discussed in step 536. The system control processor may delete or overwrite the first portion of the second copy of data and repeat steps 534 and 536 with a second portion of the second copy of data. The system control processor may repeat steps 534 and 536 any number of times until the second copy of data in its entirety has been written to the trace volume and backed up without departing from the invention.
The method may end following step 536.
Using the method illustrated in
To further clarify embodiments of the invention, a non-limiting example is provided in
Consider a scenario as illustrated in
In response to the composition request, the system control processor manager (600), at step 2, identifies computing resources to be allocated to the composed information handling system using the table illustrated in
The database application entry (662) is used by the system control processor manager (600) to ascertain the computing resource requirements for the composed information handling system. For example, the database application entry (662) specifies that a compute resource set (664), control resource set (666) and hardware resource set (668) need to be allocated to the composed information handling system to have the composed information handling system be capable of performed the workload associated with a database application. The compute resource set (664) specified by the entry includes one processor and one gigabyte of memory, the control resource set (666) includes backup generation for stored data, and the hardware resource set (668) includes one terabyte of solid state disk space. Using the information included in the database application entry (662), the system control processor manager (600) identifies corresponding compute, control, and hardware resource sets for allocation to the composed information handling system using a telemetry data map (640) as illustrated in
As seen in
Returning to
Based on the determinations, a message, at step 4, indicating these resources of the information handling system (610) is sent to the system control processor (614). The message indicates that the compute resource set A (612), one terabyte of the solid state disk (616) storage space is to be allocated to the composed information handling system, and the solid state disk (616) is also to be used as the trace volume (622).
In response to the first message, at step 5, the system control processor (614) determines that one terabyte of the solid state disk (616) should be presented by virtualizing a terabyte of the solid state disk (616) as the storage resource (620). Additionally, the system control processor (614) determines that one gigabyte of the solid state disk (616) should be virtualized by virtualizing a gigabyte of the solid state disk (616) to generate a trace volume (622). The system control processor (614) generates a first appropriate address translation table associated with the storage resource (620) to present the one terabyte of storage as the storage resource (620). The system control processor (614) also generates a second appropriate address translation table associated with the trace volume (622) to use the trace volume (622) to store duplicative data written to the solid state disk (616) and to back up the aforementioned data. The trace volume (622) is not presented to the compute resource set A (612), and is transparent to compute resource set A (612). At step 6, the system control processor uses the first and second appropriate address tables to obtain the storage resource (620) and the trace volume (622) from the solid state disk (616).
At step 7, the system control processor (614) determines that data generated by compute resource set A (612) is to be stored in the storage resource (620), duplicated and stored in the trace volume (622), and backed up using the trace volume according to the table of
At step 9, the database application executing on compute resource set A (612) generates data. Consequently, at step 10, compute resource set A (612) sends the generated data and a bare metal communication to the system control processor (614) indicating that the data is to be written to the storage resource (620).
In response to obtaining the bare metal communication and the data, at step 11, the system control processor (614) generates two copies of the data, a first copy and a second copy. After generating the copies of data, at step 12, the system control processor (614) writes the first copy of data to the storage resource (620). Then, at step 13, the system control processor (614) writes the second copy of data to the trace volume (622).
After the second copy of data is stored in the trace volume (622), at step 14, the system control processor identifies a backup trigger event. The backup trigger event is that the trace volume (622) has reached data storage capacity, as the second copy of data was one gigabyte of data. In response to identifying the trigger event, the system control processor (614) generates a backup of the second copy of data in the trace volume (622). After generating the backup, at step 15, the system control processor (614) sends the backup to a backup storage (630), where the backup is stored.
