Abstract: A system includes storage devices storing data units. Each data unit is stored on one of the storage devices. The system includes a processor, and a non-transitory computer-readable data storage medium storing computer-executable code. The processor executes the code to correlate workloads to the data units with respect to which of the workloads access which of the data units, and when the workloads access the data units.

Abstract: Additional workloads are assigned among servers in a power-efficient manner. For each of a plurality of servers, a stored power efficiency/capacity utilization relationship is accessed, current component power consumption values are obtained, and a current power consumption efficiency is calculated. An amount of capacity utilization necessary to perform an additional workload is obtained, and a predicted power consumption efficiency is determined for each server.

The workload is then assigned to the server identified as having the greatest predicted power consumption efficiency. Alternatively, the workload may be assigned to the server identified as having the greatest improvement in power consumption efficiency.
