Abstract
In this paper we focus on the video storage unit of a video server. We present a new, flexible data placement strategy for independent parallel disk arrays. The trade-off between utilization efficiency and interactive delay is investigated for this data placement strategy. Based on this trade-off, we show the advantage of video servers supporting a range of interactivity QoS. For our data placement strategy, we show that using scalable video improves the utilization and interactivity performance of a video server. We use three-layer, scalable MPEG2 digital video to support resolution QoS at a video server. Finally, we show that the data placement strategy reduces the complexity of admission control at the video server to that of a single disk system.
