摘要
独立磁盘冗余阵列(RAID)技术是解决CPU处理速度和I/O系统能力之间瓶颈的有效方法.本文介绍一种采用Reed-Solomon(RS)码作为冗余校验编码的新型的容错模型,其纠错能力为纠单个突发错和纠双删除错.本文将详细论述和分析这种容错模式的可靠性,并同N+1奇偶校验模式的可靠性进行了比较.
Redundant Array of Inexpensive Disks (RAID) is the best way to reduce the disparity between the processing speed of CPU and the ability of I/O system. A new fault tolerant model using RS (Reed-Solomon) code is proposed in thispaper. The error correcting ability of RAID with such model can correct singleburst-error and double-erasure-errors.This paper mainly discusses the reliability ofRAID system using RS code.
