We propose a systems approach to providing video service that integrates the multi-resolution data generated by scalable compression algorithms with the high-bandwidth, high-capacity storage provided by disk arrays. We introduce two layout strategies for storing multi-resolution video data on magnetic disk arrays, which vary in the degrees of parallelism and concurrency they use to satisfy requests. We also present the event-driven simulator that we used to evaluate these layout strategies. Our simulation results show that striping video data over disks in an array can provide up to a two-fold increase in the number of viewers supported. In addition, the storage of multiple video resolutions allows a video file server to satisfy considerably more user requests than a server that stores a single resolution of video data.
