摘要： Performing a tune-up procedure on a storage device including determining, during a boot process, that a first storage device is available for a tune-up procedure, wherein the tune-up procedure prepares the first storage device for use after being offline; reserving the first storage device to perform the tune-up procedure, wherein reserving the first storage device prevents another system from performing the tune-up procedure on the first storage device; and executing the tune-up procedure on the first storage device.

摘要： Data protection in a storage system that includes a plurality of Non-Volatile Memory Express (‘NVMe’) Solid State Drives (‘SSDs’), including: retrieving, from a plurality of NVMe SSDs (‘Non-Volatile Memory Express Solid State Drives’) of a storage system, one or more unencrypted shares of a master secret; reconstructing the master secret using the shares of the master secret; decrypting one or more encrypted device keys using the master secret; and using the decrypted device keys to perform a plurality of accesses to one or more of the NVMe SSDs.

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： Periodically re-encrypting user data stored on a storage device, including: detecting that a data encryption key should be decommissioned; and for user data stored on the storage device that is encrypted with the data encryption key: reading the user data that is encrypted with the data encryption key from the storage device; re-encrypting the user data utilizing a current data encryption key; and writing the user data that is encrypted utilizing the current data encryption key to the storage device.
