Abstract

The immensity of the data transfer requirements of multimedia objects will require multimedia servers to be founded on disk arrays. To effectively utilize a disk array, and hence to maximize the number of clients that can be serviced simultaneously, a multimedia server must interleave the storage of each media stream among the disks in the array. In this paper we identify two placement policies for organizing storage of multimedia objects on disk arrays. We present methods for optimizing the performance of server for both the placement policies, and empirically validate and evaluate the methods through extensive trace driven simulation.
