Patent ID: 7290086

Claim:
A storage system, comprising: a first storage system, the first storage system comprising a first cluster processor complex, a first fixed block adapter and a first storage array; a first host coupled to the first storage system; a second storage system, the second storage system comprising a second cluster processor complex, a second fixed block adapter and a second storage array, the second storage system queuing event information in a memory as the event information becomes available; a second host coupled to the first storage system; and an open source path coupling the first and second fixed block adapter; wherein the first cluster processor complex and first fixed block adapter of the first storage system are configured to provide asynchronous status messaging by transmitting a Read Message to the second fixed block adapter, wherein the Read Message requests return of asynchronous event information from the second storage system and the second fixed block adapter asynchronously returning event information queued in the memory of the second storage system in response to receipt of the Read Message.
