• This paper presents a novel data placement and retrieval scheme for video-on-demand systems. In particular, a zone-based data placement scheme is employed to reduce the average seek time of the disk array storage system and thus increase the disk access bandwidth to allow the video server provide more services of video programs concurrently. Furthermore, due to the inherent nature of video access, a popular program always requires more accesses and therefore occupies more disk I/O bandwidth as request for serving such program increases. A new retrieval strategy is proposed to maintain a single copy of each video program disregarding the popularity of the video programs, and to achieve maximum I/O throughput of the video server.
