Abstract

RAID systems have been used as a mass storage system with high parallelism and availability. Especially RAID systems with parity declustering are widely studied as a technique to provide high fault tolerancy and availability by reducing performance degradation in case of disk failures. In this paper, a new organization of parity declustering with distributed spare units is proposed. And in normal mode where there are no failures, it is shown that these organization can improve the performance of RAID systems. By simulation methods, it is proved that the performance of RAID system in normal mode is improved by 5 to 15%.
