Abstract
Disk striping is essential in Video-On-Demand servers to allow concurr ent access for a large number of users to the same copy of a video obj ect. On the other hand, disk striping makes the system more vulnerable to component failures. We propose a replication scheme for video cont ent and an associated I/O scheduling algorithm that enables the system to tolerate a component failure. The scheme, called doubly-striped mi rrors, compares favorably to other approaches for implementing redunda ncy such as RAID in terms of cost, bandwidth efficiency, buffer usage and system availability.
