Abstract
A method and apparatus to exercise and manage a related set of power managed storage devices is described. In one example a method includes receiving a request to allow a transition of the set of storage devices from a first power state to a second power state, determining a wear level for each device in the set, comparing the determined wear levels to thresholds, testing data integrity for each device in the set, and if the wear level does not exceed the threshold and the data integrity tests are passed, then commanding the requested power state transition.
