A MULTIMEDIA STORAGE-SYSTEM FOR ON-DEMAND PLAYBACK

This paper presents the design of a multimedia storage system for on-d emand playback. The design stresses effective utilization of disk band width with minimal data buffer to minimize overall system costs. The d esign procedure is most distinctive in the following two aspects: 1. I t bases on a tight upper bound of the lumped disk seek time for the Sc an disk scheduling algorithm to achieve effective utilization of disk bandwidth. 2. It starts with a general two-level hierarchical disk arr ay structure to derive the optimal configuration for specific requirem ents.
