Abstract :
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
