EEO: An Efficient MDS-Like RAID-6 Code for Parallel Implementation

Free registration required

Executive Summary

In recent years, researchers have found that some XOR erasure codes lead to higher performance and better throughput in fault-tolerant distributed data storage applications. However, little consideration has been given to the advantages of parallel processing or hardware implementations taking advantage of the emergence of multi-core processors. This paper presents an efficient horizontal MDS-like (Maximum Distance Separable) RAID-6 scheme, called EEO, which significantly improves the performance of the decoding procedure in parallel implementations with little storage overhead.
