Abstract
A method and apparatus to control and manage a power state in a related set of storage devices is described. In one example a method includes, determining an idleness measure at the file system, the idleness measure indicating availability requirements of the device set, and setting an idle state based on the idleness measure. The method also includes receiving the idle state setting at the storage subsystem, determining whether the idle state setting is different from a current state of the device set, determining whether to change the idle state of the device set if the idle state setting is different from the current state of the device set, the determining being based on information about the device set. The method also includes commanding the device set to change the current idle state to correspond to the idle state setting based on determining whether to change the idle state.
