In past years, various real-time disk scheduling algorithms have been developed to heuristically employ a seek-optimizing SCAN scheme for an EDF schedule to reduce the disk service time. For example, the well-known SCAN-EDF scheme first schedules disk tasks with the earliest deadlines. If two ...

By scheduling snapshot queries on segments in a round-robin fashion,n+ 1 segments of disk space are sufficient to always have a checkpoint ofnsegments of memory. The constant-size flip buffer ensures predictability. The data is written to disk by the controller thread. ...
For mixed-media workload, disk scheduling strategies have to guarantee the QoS (Quality of Service) of requests with timing constraints while optimizing the disk utilization. In this paper, we present a novel real-time disk scheduling algorithm which optimizes the seek time overhead of all ...
