Abstract
An array may comprise a plurality of disk drives and a controller coupled to the plurality of drives. The controller may be configured to initiate spin-up of one or more first disk drives of the array; determine when each of the first disk drive(s) of the array for which spin-up was initiated reaches a predetermined spin rate that is less than a target spin rate at which the disk drive is ready to process data access commands; and initiate spin-up of one or more second disk drives of the array as the first disk drive(s) is determined to have reached the predetermined spin rate.
