Abstract

Many computer applications require moving data from/to disk devices. Since the throughput of disk devices is extremely sensitive to the locality of accesses, the disk schedulers proposed in the literature typically assume the knowledge of the disks' physical parameters (e.g. seek and rotational latency) to meet the different Quality of Service requirements. Unfortunately, the unavoidable discrepancies between the estimated and actual values of such parameters affect the service guarantees, both in terms of response time and disk bandwidth distribution.
