Abstract

Disk arraus are using to enhance data transfer rate and I/O performance in multimedia applications which need a high-performance storage device with large storage capacity and high-speed network. As performance varies with configuration and data layout scheme, disk array characteristic variables must be appropriately determined in designing disk array architecture for a specific application. In this paper, in order to design a disk array architecture as a storage server of a small-scale VOD system, we evaluate performance of a disk array to choose the number of disks in the array, disk array configuration, a degree of declustering for a given data block size of continuous media file system and I/O request size through simulation. Simulation result shows that RAID level 5 with 5 disks is a suitable candidate for the disk array architecture which provides MPEG-2 files with a rate of 6Mbps. Moreover, we show that stripe unit is 64KB and a layout scheme is contiguous placement.
