Abstract
Write transfer resource management in a data storage system in accordance with the present description includes overdue write transfer management logic which detects whether or not an established write set has become stale. In one embodiment, a determination is made as a function of whether a write transfer from a host and associated with an established write transfer set is overdue as measured by a time-out period of time. Upon determination that an established write transfer set has become stale, the stale write set is removed and the resources associated with the removed write set are freed for use by other write sets, significantly improving system performance. Other features and aspects may be realized, depending upon the particular application.
