  • Device selection by a disk adapter scheduler
    Patent number: 6904470
    Abstract: A scheduler for selecting a logical volume for scheduling pending I/O tasks for job generation. The scheduler includes a main scheduler that selects from among multiple sub-schedulers that operate according to different scheduling approaches, e.g., high priority read I/O request scheduling, urgency of non-read I/O tasks, as well as load balancing and round robin schemes. In selecting a sub-scheduler, the main scheduler considers the amount of time allocated to performing read I/O requests, as well as the level of urgency associated with the logical volumes and the disk adapter that manages those logical volumes for non-read I/O tasks.
