Abstract
A network switch is disclosed for resolving requests from a plurality of host initiators by scheduling access to a plurality of storage systems. The network switch comprises a plurality of multi-port switches interconnected to form a switched fabric, the multi-port switches for routing requests to the plurality of storage systems and for receiving scheduling data from each of the plurality of storage systems. The network switch further comprises a memory for storing the scheduling data, and a microprocessor, responsive to the scheduling data stored in the memory, for executing a scheduling algorithm to schedule the requests. The scheduling data is transferred automatically from each storage system to the memory through the multi-port switches without the microprocessor requesting the scheduling data from each storage system.
