The Evaluation of Video Layout Strategies on a High-Bandwidth File Server

We propose a systems approach to providing video service which integrates the multi-resolution data generated by scalable compression algorithms with the high-bandwidth, high-capacity storage provided by disk arrays. The results of our simulations show that the storage of multi-resolution video permits service to considerably more users than the storage of single-resolution video. In addition, retrieval of data striped across the disks of an array can be performed much more efficiently than retrieval from a single disk.
