Patent abstract
Apparatus and systems, as well as methods and articles, may operate to sequence write operations and journal a portion of write data in a dual-parity redundant array of inexpensive disks (RAID) sub-system such that one or more parity strips in a stripe are consistent with target stripe data during the write operations, such that the consistency of the parity strips is determinant following an unexpected RAID sub-system reset occurring during the write operations, and such that the parity strips and the target stripe data are recoverable following a disk drive failure and a power failure occurring during the write operations.
