Abstract

Systems and methods presented herein provide a storage system that adaptively powers-down one or more disk drives based on the predicted idle time of each disk drive. One embodiment includes a storage controller that includes a processor operable to track idle durations of the disk drive. When an idle duration ends, the processor associates the idle duration with a time window that includes that idle duration. Each time window is associated with a number of previous idle durations of the disk drive. Upon detection of a current idle duration, the processor identifies a time window with the highest number of previous idle durations of the disk drive. Then, the processor determines whether a maximum time associated with the identified time window exceeds a predetermined threshold. When the maximum time exceeds the predetermined threshold, the processor powers-down the disk drive.
