ABSTRACT:
A host activity measure indicative of a frequency of disk access commands received by a disk drive is determined, and then compared against a host activity threshold. A subsystem activity measure indicative of an activity level of a disk drive subsystem is also determined, and then compared against a subsystem activity threshold. Based at least in part on a determination that 1) the host activity measure is indicative of a greater frequency of disk access commands than the host activity threshold, and 2) the subsystem activity measure is indicative of less activity than the subsystem activity threshold, an operating frequency of a disk drive processor is increased.
