Abstract
This paper investigates the performance of redundant array of inexpensive disks (RAID) with a level of 5 by using a Markov model. Considering RAID systems cannot be adequately modeled using a single queuing model, we use four modes to model the RAID-5 system. The analytical model is verified by simulation through a Q+ simulation software package. The results obtained from the Markov model are very close to the Q+ simulation results. Additionally, several simulation scenarios are provided to demonstrate the relationship of the number of disks and the response times.
