Multipath I/O(A Microsoft multipathing solution that enables more than one read/write path to a logical unit number (LUN). With MPIO, multipathing is achieved by assigning multiple Fibre Channel host bus adapter ports or multiple iSCSI initiator adapters on a server to the same LUN, and then configuring that server to use MPIO)
multipathing(In storage technologies, a solution that increases availability and path failover by providing multiple paths from a server or cluster to a storage subsystem. In the event that the path being used fails, multipathing logic uses an alternate path for I/O so that applications can still access their data)
