摘要

建立了RAID-5的随机Petri网(SPN)模型。利用该模型及其同构马尔可夫链，可以计算出小写大I/O请求时RAID中磁盘驱动器的平均利用率。这为我们提供了一种很好的评价RAID性能的方法。

Utilization of disk drives for RAID

A stochastic Petri nets (SPN) model of RAID-5 is constructed. With the model and its isomorphic Markov chain, the average utilization of disk drives in RAID for small write and large I/O request can be calculated. It provides us a good method to evaluate the performance of RAID in the paper.
