Method for dispatching access requests to a direct access storage deivce |
摘要 |
A method for dispatching input/output access requests to a direct access storage device (DASD) is disclosed. Each of a group of I/O access requests to DASD is assigned into one of at least two I/O access request categories, namely, high priority I/O access requests and low priority I/O access requests. Each of a group of I/O slots within DASD is assigned into one of at least two I/O slot categories, namely, high priority I/O slots and low priority I/O slots. An I/O access request from a first one of the two I/O access request categories is sent to any one of the I/O slots. An I/O access request from a second one of the two I/O access request categories is sent to only a slot belonging to a subset of the two I/O slot categories.
