During the operation of a cloud based computing environment, in which multiple compute nodes in a network execute workloads on behalf of customers, the administrator of the environment may wish to optimize the operation of the environment to satisfy certain objectives, such as costs savings for the administrator and providing prompt and responsive cloud services to the customers. The cost savings may come in the form of reduced power usage, reduced heat production, and reduced wear on the components of the compute nodes, while the objective of providing prompt and responsive cloud services may weigh in favor of additional compute capacity through additional hardware resources devoted to a workload, higher operating speeds, higher power usage, and increased heat production and wear on the components. As such, a configuration of the compute nodes and assignment of workloads among the compute nodes that is optimized for one or more of the objectives may do so at the cost of insufficiently satisfying other objectives. Furthermore, as the cloud based computing environment performs different workloads over time and phases of resource utilization within each of the workloads may change, an initial assignment workloads among the computing nodes within the environment may vary between meeting one or more of the objectives and not meeting the objectives. As such, it is difficult, in typical cloud based environments, to determine an assignment and ongoing adjustments to the assignment of workloads among the compute nodes to consistently satisfy objectives in a way that does not reduce the achievement of other objectives.

The illustrative data center 100 differs from typical data centers in many ways. For example, in the illustrative embodiment, the circuit boards (“sleds”) on which components such as CPUs, memory, and other components are placed are designed for increased thermal performance In particular, in the illustrative embodiment, the sleds are shallower than typical boards. In other words, the sleds are shorter from the front to the back, where cooling fans are located. This decreases the length of the path that air must to travel across the components on the board. Further, the components on the sled are spaced further apart than in typical circuit boards, and the components are arranged to reduce or eliminate shadowing (i.e., one component in the air flow path of another component). In the illustrative embodiment, processing components such as the processors are located on a top side of a sled while near memory, such as DIMMs, are located on a bottom side of the sled. As a result of the enhanced airflow provided by this design, the components may operate at higher frequencies and power levels than in typical systems, thereby increasing performance. Furthermore, the sleds are configured to blindly mate with power and data communication cables in each rack 102A, 102B, 102C, 102D, enhancing their ability to be quickly removed, upgraded, reinstalled, and/or replaced. Similarly, individual components located on the sleds, such as processors, accelerators, memory, and data storage drives, are configured to be easily upgraded due to their increased spacing from each other. In the illustrative embodiment, the components additionally include hardware attestation features to prove their authenticity.
Furthermore, in the illustrative embodiment, the data center 100 utilizes a single network architecture (“fabric”) that supports multiple other network architectures including Ethernet and Omni-Path. The sleds, in the illustrative embodiment, are coupled to switches via optical fibers, which provide higher bandwidth and lower latency than typical twisted pair cabling (e.g., Category 5, Category 5e, Category 6, etc.). Due to the high bandwidth, low latency interconnections and network architecture, the data center 100 may, in use, pool resources, such as memory, accelerators (e.g., graphics accelerators, FPGAs, ASICs, etc.), and data storage drives that are physically disaggregated, and provide them to compute resources (e.g., processors) on an as needed basis, enabling the compute resources to access the pooled resources as if they were local. The illustrative data center 100 additionally receives usage information for the various resources, predicts resource usage for different types of workloads based on past resource usage, and dynamically reallocates the resources based on this information.
The racks 102A, 102B, 102C, 102D of the data center 100 may include physical design features that facilitate the automation of a variety of types of maintenance tasks. For example, data center 100 may be implemented using racks that are designed to be robotically-accessed, and to accept and house robotically-manipulatable resource sleds. Furthermore, in the illustrative embodiment, the racks 102A, 102B, 102C, 102D include integrated power sources that receive a greater voltage than is typical for power sources. The increased voltage enables the power sources to provide additional power to the components on each sled, enabling the components to operate at higher than typical frequencies.
In various embodiments, dual-mode optical switches may be capable of receiving both Ethernet protocol communications carrying Internet Protocol (IP packets) and communications according to a second, high-performance computing (HPC) link-layer protocol (e.g., Intel's Omni-Path Architecture's, Infiniband) via optical signaling media of an optical fabric. As reflected in
MPCMs 916-1 to 916-7 may be configured to provide inserted sleds with access to power sourced by respective power modules 920-1 to 920-7, each of which may draw power from an external power source 921. In various embodiments, external power source 921 may deliver alternating current (AC) power to rack 902, and power modules 920-1 to 920-7 may be configured to convert such AC power to direct current (DC) power to be sourced to inserted sleds. In some embodiments, for example, power modules 920-1 to 920-7 may be configured to convert 277-volt AC power into 12-volt DC power for provision to inserted sleds via respective MPCMs 916-1 to 916-7. The embodiments are not limited to this example.
MPCMs 916-1 to 916-7 may also be arranged to provide inserted sleds with optical signaling connectivity to a dual-mode optical switching infrastructure 914, which may be the same as—or similar to—dual-mode optical switching infrastructure 514 of
Sled 1004 may also include dual-mode optical network interface circuitry 1026. Dual-mode optical network interface circuitry 1026 may generally comprise circuitry that is capable of communicating over optical signaling media according to each of multiple link-layer protocols supported by dual-mode optical switching infrastructure 914 of
Coupling MPCM 1016 with a counterpart MPCM of a sled space in a given rack may cause optical connector 1016A to couple with an optical connector comprised in the counterpart MPCM. This may generally establish optical connectivity between optical cabling of the sled and dual-mode optical network interface circuitry 1026, via each of a set of optical channels 1025. Dual-mode optical network interface circuitry 1026 may communicate with the physical resources 1005 of sled 1004 via electrical signaling media 1028. In addition to the dimensions of the sleds and arrangement of components on the sleds to provide improved cooling and enable operation at a relatively higher thermal envelope (e.g., 250 W), as described above with reference to
As shown in
In another example, in various embodiments, one or more pooled storage sleds 1132 may be included among the physical infrastructure 1100A of data center 1100, each of which may comprise a pool of storage resources that is available globally accessible to other sleds via optical fabric 1112 and dual-mode optical switching infrastructure 1114. In some embodiments, such pooled storage sleds 1132 may comprise pools of solid-state storage devices such as solid-state drives (SSDs). In various embodiments, one or more high-performance processing sleds 1134 may be included among the physical infrastructure 1100A of data center 1100. In some embodiments, high-performance processing sleds 1134 may comprise pools of high-performance processors, as well as cooling features that enhance air cooling to yield a higher thermal envelope of up to 250 W or more. In various embodiments, any given high-performance processing sled 1134 may feature an expansion connector 1117 that can accept a far memory expansion sled, such that the far memory that is locally available to that high-performance processing sled 1134 is disaggregated from the processors and near memory comprised on that sled. In some embodiments, such a high-performance processing sled 1134 may be configured with far memory using an expansion sled that comprises low-latency SSD storage. The optical infrastructure allows for compute resources on one sled to utilize remote accelerator/FPGA, memory, and/or SSD resources that are disaggregated on a sled located on the same rack or any other rack in the data center. The remote resources can be located one switch jump away or two-switch jumps away in the spine-leaf network architecture described above with reference to
In various embodiments, one or more layers of abstraction may be applied to the physical resources of physical infrastructure 1100A in order to define a virtual infrastructure, such as a software-defined infrastructure 1100B. In some embodiments, virtual computing resources 1136 of software-defined infrastructure 1100B may be allocated to support the provision of cloud services 1140. In various embodiments, particular sets of virtual computing resources 1136 may be grouped for provision to cloud services 1140 in the form of SDI services 1138. Examples of cloud services 1140 may include—without limitation—software as a service (SaaS) services 1142, platform as a service (PaaS) services 1144, and infrastructure as a service (IaaS) services 1146.
In some embodiments, management of software-defined infrastructure 1100B may be conducted using a virtual infrastructure management framework 1150B. In various embodiments, virtual infrastructure management framework 1150B may be designed to implement workload fingerprinting techniques and/or machine-learning techniques in conjunction with managing allocation of virtual computing resources 1136 and/or SDI services 1138 to cloud services 1140. In some embodiments, virtual infrastructure management framework 1150B may use/consult telemetry data in conjunction with performing such resource allocation. In various embodiments, an application/service management framework 1150C may be implemented in order to provide QoS management capabilities for cloud services 1140. The embodiments are not limited in this context.
As shown in
Additionally, in the illustrative embodiment, the orchestrator server 1240 is configured to analyze the telemetry data and determine whether adjustments to the assignment of the workloads among the server and adjustments to the operations of the components of the managed nodes 1260 could be made to increase the satisfaction (also referred to herein as achievement) of one or more of the objectives without decreasing the achievement of any of the other objectives. In other words, in the illustrative embodiment, each objective may be satisfied to a varying degree. For example, in the illustrative embodiment, increasing the achievement may be performed by decreasing the error (e.g., difference) between the measured value (e.g., an operating temperature of a managed node 1260) and the target value (e.g., a target operating temperature). Conversely, decreasing the achievement may be performed by increasing the error (e.g., difference) between the measured value and the target value. By continually making such adjustments to the assignments of the workloads to the managed nodes 1260, the orchestrator server 1240 repeatedly makes “Pareto improvements”, until the orchestrator server 1240 determines that no further adjustments can be made without negatively impacting the achievement of one or more of the goals, in which case the orchestrator server 1240 determines the assignment of the workloads among the managed nodes 1260 to be “Pareto-efficient.” As such, by adjusting the assignment of the workloads among the managed nodes 1260 (i.e., adjusting the allocation of resources to the workloads), the orchestrator server 1240 may provide a balanced, Pareto-efficient solution, that serves all of the objectives on an ongoing basis.

In the illustrative environment 1400, the network communicator 1420, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof as discussed above, is configured to facilitate inbound and outbound network communications (e.g., network traffic, network packets, network flows, etc.) to and from the orchestrator server 1240, respectively. To do so, the network communicator 1420 is configured to receive and process data packets from one system or computing device (e.g., the client device 1220) and to prepare and send data packets to another computing device or system (e.g., the managed nodes 1260). Accordingly, in some embodiments, at least a portion of the functionality of the network communicator 1420 may be performed by the communication circuitry 1308, and, in the illustrative embodiment, by the NIC 1310.
The telemetry monitor 1430, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof as discussed above, is configured to collect the telemetry data 1402 from the managed nodes 1260 as the managed nodes 1260 execute the workloads assigned to them. The telemetry monitor 1430 may actively poll each of the managed nodes 1260 for updated telemetry data 1402 on an ongoing basis or may passively receive telemetry data 1402 from the managed nodes 1260, such as by listening on a particular network port for updated telemetry data 1402. The telemetry monitor 1430 may further parse and categorize the telemetry data 1402, such as by separating the telemetry data 1402 into an individual file or data set for each managed node 1260.
The resource manager 1440, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof, is configured to generate data analytics from the telemetry data 1402, identify the workloads, classify the workloads, identify trends in the resource utilization of the workloads, identify resource contention among the workloads, predict future resource utilizations of the workloads and future resource contention among the workloads, determine whether the assignment of the workloads among the managed nodes 1260 is Pareto-efficient, and adjust the assignments of the workloads to the managed nodes 1260 and the settings of the managed nodes 1260 to provide Pareto improvements (i.e., increasing the achievement of at least one resource allocation objective without negatively affecting the achievement of any other resource allocation objective). To do so, the resource manager 1440 includes a workload labeler 1442, a workload classifier 1444, a workload behavior predictor 1446, and a multi-objective analyzer 1448 that includes a Pareto efficiency determiner 1450, a workload placer 1452, and a node settings adjuster 1454. The workload labeler 1442, in the illustrative embodiment, is configured to assign a workload label 1406 to each workload presently performed or scheduled to be performed by one or more of the managed nodes 1260. The workload labeler 1442 may generate the workload label 1406 as a function of an executable name of the workload, a hash of all or a portion of the code of the workload, or based on any other method to uniquely identify each workload. The workload classifier 1444, in the illustrative embodiment, is configured to categorize each labeled workload based on the resource utilization of each workload. For example, the workload classifier 1444 may categorize one set of labeled workloads as being consistently processor intensive, another set of labeled workloads as being consistently memory intensive, and another set of workloads as having phases of different resource utilization (high memory use and low processor use, followed by high processor use and low memory use, etc.).
The workload behavior predictor 1446, in the illustrative embodiment, is configured to analyze the telemetry data 1402 and the workload classifications 1408 to predict future resource utilization needs of the various workloads based on their previous usage and potential resource contention among the workloads. The workload behavior predictor 1446 may be configured to identify patterns in the resource utilization phases (e.g., period of high processor usage and low memory usage, periods of low processor usage and high memory usage, etc.) of the workloads, determine a present resource utilization phase of a given workload, predict the next resource utilization phase based on the patterns, and determine an amount of remaining time until the workload transitions to the predicted resource utilization phase. The multi-objective analyzer 1448, in the illustrative embodiment, is configured to balance the resource allocation objectives defined in the resource allocation objective data 1404, determine, based on the telemetry data 1402, whether the present allocation of the resources in the managed nodes 1260 is Pareto-efficient, and if not, determine an adjustment that provides a Pareto improvement (e.g., an increase in the achievement of at least one of the objectives without decreasing the achievement of any of the other objectives). To do so, in the illustrative embodiment, the multi-objective analyzer 1448 includes the Pareto efficiency determiner 1450, the workload placer 1452, and the node settings adjuster 1454.
The Pareto efficiency determiner 1450 in the illustrative embodiment, is configured to determine, as a function of the telemetry data 1402, including the present resource utilizations of the workloads and the predicted behavior of the workloads, whether an adjustment can be made to any of the assignments of the workloads and/or the settings of the components of the managed nodes 1260 to increase the achievement of one or more of the resource allocation objectives without decreasing the achievement of the other resource allocation objectives. In the illustrative embodiment, the Pareto efficiency determiner may do so by modeling or simulating the set of managed nodes 1260, their power consumption, heat generation, compute capacity, and other factors in response to various adjustments to the assignments of workloads and/or the setting of components within the managed nodes 1260, define a Pareto frontier indicative of a set of resource allocations that are all Pareto-efficient, determine whether the present resource allocation is already on the Pareto frontier, and if not, what adjustment to the allocations would reach the Pareto frontier. The Pareto efficiency determiner may determine the Pareto frontier, P(Y), as follows:
f:Rn→Rm (Equation 1)
In the above equation, f is a function of the set of managed nodes 1260, modeled by the Pareto efficiency determiner, that is indicative of the response of the managed nodes 1260 to adjustments to the assignments of workloads. Rn is a metric space of possible allocations (i.e., assignments of workloads) and Rm represents a set of criterion vectors. In the following equation, X is a compact set of feasible decisions in the metric space, le, and Y is the feasible set of criterion vectors in Rm, as follows:
Y={y∈Rm:y=f(x),x∈X} (Equation 2)
Furthermore, a point y″ defined in Equation 3 below dominates another point y′ defined in Equation 4.
y″∈Rm (Equation 3)
y′∈Rm (Equation 4)
As such, the Pareto frontier may be represented as follows:
P(Y)={y′∈Y:{y″∈Y:y″>y′,y″≠y′}=Ø} (Equation 5)
The workload placer 1452, in the illustrative embodiment, is configured to initially assign workloads to the various managed nodes 1260 and reassign the workloads among the managed nodes 1260 to provide a Pareto improvement identified by the Pareto efficiency determiner 1450. Similarly, the node settings adjuster 1454, in the illustrative embodiment, is configured to apply one or more adjustments to the settings within the managed nodes 1260 to provide or restrict the resources available to the workloads in accordance with a Pareto improvement determined by the Pareto efficiency determiner 1450. The settings may be associated with the operating system and/or the firmware or drivers of the components of the managed nodes 1260.
It should be appreciated that each of the workload labeler 1442, the workload classifier 1444, the workload behavior predictor 1446, the multi-objective analyzer 1448, the Pareto efficiency determiner 1450, the workload placer 1452, and the node settings adjuster 1454 may be separately embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof. For example, the workload labeler 1442 may be embodied as a hardware component, while the workload classifier 1444, the workload behavior predictor 1446, the multi-objective analyzer 1448, the Pareto efficiency determiner 1450, the workload placer 1452, and the node settings adjuster 1454 are embodied as virtualized hardware components or as some other combination of hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof.

After receiving the resource allocation objective data 1404, in the illustrative embodiment, the method 1500 advances to block 1514 in which the orchestrator server 1240 assigns initial workloads to the managed nodes 1260. In the illustrative embodiment, the orchestrator server 1240 has not received telemetry data 1402 that would inform a decision as to where the workloads are to be assigned among the managed nodes 1260. As such, the orchestrator server 1240 may assign the workloads to the managed nodes 1260 based on any suitable method, such as assigning the each workload to the first available managed node that is idle (i.e., is not presently executing a workload), randomly assigning the workloads, or by any other method.
Having assigned the workloads, the method 1500 advances to block 1516 in which the orchestrator server 1240 receives telemetry data 1402 from the managed nodes 1260 as the workloads are performed (i.e., executed).

The orchestrator server 1240 may additionally or alternatively receive non-volatile memory utilization data indicative of the amount of data stored and/or retrieved from the data storage devices 1312 and/or a frequency at which each workload issues write requests and/or read requests to the data storage devices 1312 in each managed node 1260, as indicated in block 1532.
In receiving the telemetry data 1402, the orchestrator server 1240 may additionally or alternatively receive network utilization data indicative of an amount of network bandwidth (e.g., capacity of the communication circuitry) used by each workload performed by each managed node 1260, as indicated in block 1534.

In the illustrative embodiment, as indicated in block 1548, in generating the data analytics, the orchestrator server 1240 also determines present contention for resources by the workloads. For example, the orchestrator server 1240 may identify two workloads executed concurrently by the same managed node 1260 that are both presently in a high processor utilization phase, causing contention for that resource of the managed node 1260. Similarly, the orchestrator server 1240 may identify workloads executed by a particular managed node 1260 that are concurrently in a phase of high memory utilization or high network bandwidth utilization, causing contention for those resources. In doing so, the orchestrator server 1240 may determine whether, at the heightened resource utilization, the available capacity of the resource subject to contention is less than the amount requested by the workloads executed by that managed node 1260, and if so, store an indicator to potentially adjust the assignment of those workloads among the managed nodes 1260. Additionally, in the illustrative embodiment, the orchestrator server 1240 predicts future resource utilization phases of the workloads, such as by comparing a present resource utilization of each workload to the trends identified in block 1540 to determine the present phase of each workload, and then identifying the upcoming phases of the workloads from the trends, as indicated in block 1550. In doing so, in block 1552, the orchestrator server 1240 predicts future contention for resources using an analysis similar to that described above in block 1548, but using the predicted future resource utilization rather than the present resource utilization of the workloads.
After generating the data analytics, the method 1500 advances to block 1554, in which the orchestrator server 1240 determines whether the workload assignments are Pareto-efficient. In doing so, in the illustrative embodiment, the orchestrator server 1240 determines whether an adjustment can be made to the workload assignments to increase the achievement of a resource allocation objective (e.g., a target performance), without decreasing the achievement of any other resource allocation objective (e.g., a target power consumption, a temperature threshold, etc.), as indicated in block 1556. As described above, the orchestrator server 1240 may determine the Pareto frontier based on a model of the reactions of the managed nodes 1260 to adjustments to the assignment of workloads, and determine whether the present state of the allocation of resources is already on the Pareto frontier. In block 1558, the orchestrator server 1240 determines the subsequent steps based on whether the orchestrator server 1240 determined that the present allocation of resources (e.g., assignment of workloads) is Pareto-efficient. If so, the method 1500 loops back to block 1516 of

The orchestrator server 1240 may additionally determine node-specific adjustments, as indicated in block 1566. The node-specific adjustments may be embodied as changes to settings within one or more of the managed nodes 1260, such as in the operating system, the drivers, and/or the firmware of components (e.g., the CPU 1302, the memory 1304, the communication circuitry 1308, the one or more data storage devices 1312, etc.) to improve resource utilization. As such, in the illustrative embodiment, in determining the node-specific adjustments, the orchestrator server 1240 may determine processor throttle adjustments, such as clock speed and/or processor affinity for one or more workloads, as indicated in block 1568. Additionally or alternatively, the orchestrator server 1240 may determine memory usage adjustments, such as allocations of volatile memory (e.g., the memory 1304) and/or data storage capacity (e.g., capacity of the one or more data storage devices 1312), memory bus speeds, and/or other memory-related settings, as indicated in block 1570. Additionally or alternatively, the orchestrator server 1240 may determine network bandwidth adjustments, such as an available bandwidth of the communication circuitry 1308 to be allocated to each workload in the managed node 1260, as indicated in block 1572. Additionally or alternatively, the orchestrator server 1240 may determine one or more fan speed adjustments to increase or decrease the cooling within the managed node 1260, as indicated in block 1574.
After determining the adjustments, the method advances to block 1576 in which the orchestrator server applies the determined adjustments. In doing so, the orchestrator server 1240 may issue one or more requests to perform a live migration of a workload between two managed nodes 1260 (i.e., a workload reassignment), as indicated in block 1578. In the illustrative embodiment, the migration is live because, rather than waiting until the workloads have been completed to analyze the telemetry data 1402, the orchestrator server 1240 collects and analyzes the telemetry data 1402, and makes adjustments online (i.e., as the workloads are being performed), as described above. Additionally or alternatively, as indicated in block 1580, the orchestrator server 1240 may issue one or more requests to one or more of the managed nodes 1260 to apply the node-specific adjustments described above with reference to block 1566. After applying the adjustments, the method 1500 loops back to block 1516 of
