摘要

Cache对磁盘阵列的性能影响很大.本文从磁盘参数和通道性能两方面出发

利用排队论和Petri网模型计算磁盘阵列的性能

从理论上分析了磁盘和高速缓存各部分参数对磁盘阵列性能的影响

并提出了提高磁盘阵列性能的若干方法.

Abstract

Cache affects RAID performance very much.Considering disk parameter and channel performance

we use queue theory and Petri model to calculate RAID performance

and analyze influences of disk and Cache parameters in theory

then provide some methods to improve RAID performance.
