摘要:
Apparatus, methods, and other embodiments associated with providing a correlation between a power distribution unit(s) and a device(s) are described. One example method includes storing first time series data that identifies, on a per power distribution unit (PDU) basis, current drawn from a set of PDUs. The example method may include storing second time series data that identifies, on a per device basis, power used by a set of related devices. With the two time series data available, the method may then provide a PDU-device correlation signal that identifies a correlation between current drawn from a PDU and power used by a device.

When the maximum power consumption of a computer exceeds a currently selected power-consumption cap, a cap setting corresponding to the currently selected power-consumption cap is reduced in addition, power-cap settings corresponding to power-consumption caps between said currently selected power-consumption cap and said maximum power consumption are reduced.
摘要:
Power consumption of a group of computer systems is managed based on a maximum power consumption for the group. A power budget is determined from the power consumption of each computer system and the maximum power consumption for the group. The power budget identifies a power cap for each computer system in the group. The power caps in the power budget are distributed to the computer systems in the group.

The present invention is directed to a system and method for managing allocation of a computer resource to at least one partition of a plurality of partitions of a multiple partition computer system, the system comprising: a plurality of work load managers, with one work load manager associated with each partition of the plurality of partitions, wherein each work load manager determines a resource request value for the computer resource based on at least one priority assigned to its partition associated with the computer resource; and a partition load manager that is operative to form an allocation value for each respective partition based on a respective resource request value; wherein the system apportions the computer resource among the plurality of partitions based on the allocation values.

When the maximum power consumption of a computer exceeds a currently selected power-consumption cap, a cap setting corresponding to the currently selected power-consumption cap is reduced. In addition, power-cap settings corresponding to power-consumption caps between said currently selected power-consumption cap and said maximum power consumption are reduced.
摘要:
A system comprises a workload evaluator that is operable to receive a representative workload that is representative of competing demands for capacity of at least one shared computing resource. The workload evaluator evaluates the representative workload and computes a metric representing a degree of burstiness of demands present in the representative workload. The metric representing degree of burstiness of the representative workload may be used for estimating an upper bound on quality of service provided by a workload manager to the representative workload. The metric may also be used for evaluating at least one scheduler parameter setting of the workload manager to aid in determining an optimal parameter setting based at least in part on the estimated impact of the representative workload on QoS provided by the workload manager.
摘要:
A method comprises defining a scheduler parameter for a maximum allocation of capacity of a shared resource to a consumer for a scheduling interval. Utilization of an allocated capacity of the shared resource by the consumer during a given scheduling interval is measured, and when the allocated capacity of the shared resource is completely utilized by the consumer during the given scheduling interval, the scheduler increases the allocated capacity of the shared resource to the defined maximum allocation for the consumer for a next scheduling interval. Thus, rather than gradually increasing the allocation of capacity over many intervals, the scheduler immediately increases the allocation to a predefined maximum amount in response to an allocated amount of capacity being completely utilized during a scheduling interval.
摘要:
A system comprises a workload manager evaluator operable to receive a representative workload that is representative of competing workloads that share access to at least one shared computing resource. The workload manager evaluator is operable to evaluate performance of a scheduler that schedules access of the competing workloads to the shared computing resource according to defined control parameter values, wherein the workload manager evaluator evaluates performance of the scheduler under the representative workload for a plurality of different values of the control parameters. In certain embodiments, the workload manager evaluator determines an optimal value for the control parameters of the scheduler for scheduling access to the at least one shared computing resource for the representative workload to satisfy defined performance desires of the system.
