Abstract

The number of simultaneous displays supported by a continuous media server (e.g, Mitra) depends on the number of disk drives as well as the amount of memory in the system. To support a higher number of displays, one may increase the number of disks in the system and reorganize the placement of data to incorporate their bandwidth. This study presents alternative on-line reorganization techniques that modify the placement of data without disrupting service. We quantify the memory and disk storage requirements of these techniques using analytical models.
