A symmetric triple parity (TP) technique in an array comprising a number p of storage devices, such as disks, with p being a prime number is provided. The p disks are organized as one row parity disk, two symmetric parity disks and p-3 data disks. Phantom diagonal and anti-diagonal parity disks assumed...http://www.google.co.uk/patents/US7613984?utm_source=gb-gplus-sharePatent US7613984 - System and method for symmetric triple parity for failing storage devices
