    摘要: A novel and useful method of implementing a full coverage low power mode in a storage system comprised of one or more memory storage devices storing replicated data items. A subset of the memory storage devices is chosen whose replicated data items require the least amount of storage. If the chosen subset stores uncovered data items, these data items are copied to an auxiliary memory storage device. The storage system can enter a full coverage low power mode by powering down the chosen subset of memory storage devices.
