Abstract
A multi-device storage system can be arranged into power saving systems by placing one or more storage devices into a reduced power consuming state when the storage activity associated with the system is sufficiently reduced that an attendant decrease in throughput will not materially affect users of the storage system. Where data redundancy is provided for, a redundant storage device can be placed into the reduced power consuming state and its redundancy responsibilities can be transitioned to a partition of a larger storage device. Such transitions can be based on specific parameters, such as write cycles or latency, crossing thresholds, including upper and lower thresholds, they can also be based on pre-set times, or a combination thereof. Lifecycle information, including lifecycle information collected in real-time by storage devices on a block-by-block basis, can be utilized to obtain historical empirical data from which to select the pre-set times.
