摘要
随着ＣＰＵ速度的迅速提高，Ｉ／Ｏ与之不匹配加剧，高性能计算机面临愈来愈严重的Ｉ／Ｏ瓶颈问题，磁盘阵列作为解决这一难题的新路线有着光明的发展前景。本文针对磁盘阵列技术中目前最受关注的可靠性展开分析、计算、讨论，以建立一种公正的评价体系。
With rapid increasing of the speed of CPU and the mismatch between CPU and I/O,the bottleneck phenomenon of the computer system with high performance becomes even more serious day by day. Disk array technique is a new and bright way to solve this problem. This paper discusses and analyzes the system reliability of RAID that has been paid the most close attention to,so as to establish a justified evaluating system.
