ABSTRACT:
Provided is a method, system, an program for power management of storage units in a storage array. A power profile is accessed for a storage array including a plurality of storage units, wherein each storage unit is enabled to operate in one of a plurality of power consumption modes, and wherein the power profile indicates a power mode specifying a power consumption mode. Data is migrated from at least one storage unit to at least one storage unit designated as an active storage unit consuming power in an active power consumption mode. The power consumption mode of at least one storage unit not designated as active is altered to the specified power consumption mode indicated in the accessed profile, wherein the specified power consumption mode consumes less power than the active power consumption mode.
