Abstract
An efficient RAID-6 double parity erasure code scheme. Efficiency is provided by the addition of a single term to a diagonal parity equation. For example, in a five-wide layout (having five physical storage devices) the RAID-6 'parity diagonals' end up with six terms, which are the actual diagonal plus one more data block. As a result, no one data symbol contributes to the erasure code determined from the data symbols, such that no more than n+1 data symbols contribute to any one parity symbol.
