ABSTRACT:
In an embodiment, an apparatus is provided that may include circuitry to generate, at least in part, and/or receive, at least in part, at least one access request involving a redundant array of independent disks (RAID) storage. The storage may be capable of accessing, in response, at least in part, to the at least one request an encryption and/or parity information. The encryption may be of at least one portion of the data and/or the parity information. The encryption may be stored in (1) encrypted disk stripes in the storage such that the data is unrecoverable based solely upon remaining unencrypted portion of the data and the parity information stored in the storage, and/or (2) one or more respective disk stripes having a number that is determined based at least in part upon one or more encryption levels, if any, associated with at least one characteristic of the data.
