Abstract: | For a video-on-demand computer system, we propose a scheme which balances the load on the disks, thereby helping to solve
a performance problem crucial to achieving maximal video throughput. Our load-balancing scheme consists of two components.
The static component determines good assignments of videos to groups of striped disks. The dynamic component uses these assignments,
and features a “DASD dancing” algorithm which performs real-time disk scheduling in an effective manner. Our scheme works
synergistically with disk striping. We examine the performance of the proposed algorithm via simulation experiments. |
