Storage device parity computation

摘要

Provided are a techniques for receiving a modification to at least one data block. Parity blocks that are to be computed for the at least one data block are determined. At least one common term for computations for the determined parity blocks is determined. A first parity block from the determined parity blocks is computed that generates intermediate parity results for the common term. A second parity block from the determined parity blocks is computed using the intermediate parity results.
