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. The processor executes the code to when the workloads access the data units and/or and on which of the storage devices the data units are stored, so that at given times the data units stored on a subset of the storage devices are not being accessed by any workload. The processor executes the code to, during each given time, power off the subset of the storage devices storing the data units that are not being accessed by any workload to conserve power.

Modification of when workloads access data units and/or on which storage devices data units are stored to conserve power

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 predicted efficiency is determined using the current power consumption efficiency of the server and the stored relationship. The workload is then assigned to the server that would have the greatest improvement in power consumption efficiency.
