Abstract
Techniques for reducing power consumption in a storage system that includes a disk array enclosure (DAE). The techniques include selecting a number of active drives for inclusion in an active drive subgroup of the DAE, and designating a number of inactive (OFF or non-operational) drives for inclusion in an inactive drive subgroup of the DAE. The total number of drives included in the DAE equals the sum of the number of active drives and the number of inactive drives. The techniques further include monitoring at least one condition (e.g., storage capacity utilization, drive wear-leveling, system performance) pertaining to a power consumption of the storage system, and reducing the power consumption by dynamically adapting the number of active drives in the active drive subgroup based on the monitored condition. By dynamically adapting the number of active drives based on certain storage system conditions, significant reductions in power consumption can be achieved.
