Intelligent RAID 6 Uses Dual Independent Parity Coding Schemes for Extra Data Protection

Overview

RAID 6 is an emerging technology for shared storage systems and the large, high-capacity SATA disk arrays used in servers today. With double parity coding, intelligent RAID 6 delivers the highest level of reliability and data protection in a cost-effective solution. To produce the dual independent parity schemes in RAID 6, XOR and encoding needs to be done in hardware. The new Intel IOP333 I/O processor with Intel XScale microarchitecture was to be the first commercially available processor to provide the necessary hardware acceleration and features for RAID 6 applications.
