Paper Abstract

In multimedia applications, disk-arrays are often used to support he disk bandwidth requirements and data availability. Serious problems on available disk bandwidth and data availability could occur upon disk failure. In this paper, we discuss issues related to replicating data copies to provide high fault-tolerance required in a disk-array- based storage server. Replication and parity are two approaches to increase fault tolerance. By exploring theoretical aspects of these two concepts, we examine methods to build high availability disk arrays with multiple redundancy. The data allotment presented achieves the optimal fault-tolerance for goth triple and quadruple redundant disk arrays. Some theoretical properties of this problem are investigated.
