Modeling on the average storage response time to a single file and the RAID disk array is accomplished by using M/G/1 queuing theory, and the optimal load balancing algorithm based on this model is addressed, and its implementation method is given. The optimal stripe algorithm is effective by simulation experimental verification; it can use the corresponding SU (stripe unit) and SW (stripe width) according to the different storage access characteristics and different access flow, so it has the shortest storage access response time.
