On the data striping scheme of VBR video on zoned disk array

In this paper, we study the striping of VBR videos on zoned disk array. We apply constant read time approach and round robin block permutation scheme to solve this problem. By using dynamic programming technique, we can obtain an optimal data striping and disk layouts. Moreover, we adopt an admission control policy to dispatch requests on hard disks in order to provide guaranteed services. Simulation results show that our method achieves load balancing on hard disks of a disk array, efficiently utilizes zoned-disk bandwidths and obtains a signification improvement than the traditional data striping scheme.
