摘要： In a storage system that includes a plurality of storage devices configured into one or more write groups, quorum-aware secret sharing may include: encrypting a device key for each storage device using a master secret; generating a plurality of shares from the master secret such that a minimum number of storage devices required from each write group for a quorum to boot the storage system is not less than a minimum number of shares required to reconstruct the master secret; and storing the encrypted device key and a separate share of the plurality of shares in each storage device.

摘要： A power requirement associated with a storage device of the plurality of storage devices is determined. A set of blocks of the storage device is allocated for storage of data, wherein the set of blocks of the storage device is less than the power requirement of the storage device. User data to be stored at the storage system is received. The user data is assigned to the set of blocks for storage at the storage device.
