Yes, that's what it says in Scott's paper, which I referenced. > However, RAID 6 is RAID 5 with some STK enhancements for improved > performance and reliability. RAID 6 implements multiple parity blocks. Depending on the implementation they might be applied orthogonally, but I don't think this is canon. Because LSF only writes to disk areas that are logically zero, there has likely been substantial change to the parity generation algorithm. The performance characteristics of even the original Iceberg were vastly different from that of a pure RAID-5 box that was being marketed by STK at the time. -- David Andrews A. Duda and Sons, Inc.
