Summary :

In this paper, we present a distributed RAID style video server that addresses the problem of increasing video stream supplying capability in VOD systems. Distibuted RAID Stylemeans extending the RAID method usually applied to disks to the servers, so as to achieve improvements in performance and reliability. The great advantage of this architecture is that the linear performance improvement can be achieved by adding inexpensive servers of a diffusion model. We have implemented the RAID0 style and RAID4 style systems. A number of new features such as the array configuration method or the striping buffer are applied to them. A precise performance evaluation was made in a near practical environment, with more than 40 video streams. We tested the system, in both normal and degraded mode (server failure) and by checking frame drop rates as well as observing picture quality. An evaluation by simulation was also conducted. The results of the above evaluations agreed well with the calculation value, to confirm the feasibility of this architecture.
