Abstract
A storage control system receives an I/O request from a client for accessing storage resources that are logically divided into device groups, and determines a resource token request value associated with the I/O request and a target device group to which the I/O request is directed. The storage control system determines a number of allowed resource tokens to allocate to the client as a function of (i) the resource token request value, (ii) a sum total of resource tokens requested by other clients for accessing the target device group, and (iii) a total amount of resource tokens currently allocated to the target device group to which the I/O request is directed. The storage control system sends the determined number of allowed resource tokens to the client to thereby enable the client to limit a number of inflight I/O requests that the client issues to the storage control system.
