Disk copy scheduling determines which disks (or disk arrays) to select for videos replicated on multiple disks, minimizing disk load imbalances. Disk arm scheduling optimizes the way that disk arms are scheduled to serve multiple requests to a disk, thus maximizing the number of isochronous video streams supportable by a disk. We examine the various issues encountered in these four types of scheduling, and consider the solutions available. 1 INT... |
