Abstract
This paper studies the impact of different disk array configurations on the size of data buffer required to support video-on-demand. The study is based on a general two-level hierarchical disk array structure that provides both parallelism and concurrency. The study reveals that, for disk arrays with the same total number of disks, a higher degree of parallelism means that the minimum size of data buffer required is larger. This result provides valuable insight about how to organize the disk array in order to minimize system costs.
