Abstract:
A method, apparatus and program product implement a failover of a communication channel in a cluster fabric that transfers a state of the communication channel between windows resident in a hardware fabric interface device. The failover is desirably implemented by updating a plurality of mappings between memory resources in a host memory and hardware resources in the fabric interface device, and typically without modifying the memory resources such that involvement of a client that utilizes the communication channel in the failover is minimized or eliminated.
