Abstract: A system and method are provided for automating full stripe operations in a redundant data storage array. In a redundant storage device controller, a parity product is accumulated that is associated with an information stripe. The parity product is stored in controller memory in a single write operation. A stored parity product is then written in a storage device. The parity product may be accumulated in a RAID controller, stored in a RAID controller memory, and written in a RAID. For example, the controller may receive n data stripelets for storage. The parity product is accumulated by creating m parity stripelets, and the m parity stripelets are written into the controller memory in a single write operation. Alternately, the controller may receive (n+m?x) stripelets from a RAID with (n+m) drives, recover x stripelets, and write x stripelets into controller memory in a single write operation.
