6-1-2009 P-Code : A New RAID-6 Code with Optimal Properties

Abstract

RAID-6 significantly outperforms the other RAID levels in disk-failure tolerance due to its ability to tolerate arbitrary two concurrent disk failures in a disk array. The underlying parity array codes have a significant impact on RAID-6’s performance. In this paper, we propose a new XOR-based RAID-6 code, called the Partition Code (P-Code). P-Code is a… (More)
