Parallel, hence high speed, data transfer is possible with disk arrays on which files are interleaved on many disks. For disk arrays where data are interleaved in block units, the size of a block is a major performance parameter. Therefore it is important to find an optimal block size in order to maximize the bandwidth of disk arrays. In this paper, we analyze the effects of workload, disk parameters, and the number of disks on the block size. Based on the analysis, we present a method to find an optimal block size for a disk array.
