Summary
Yes (FC, iSCSI)
Details
Multipathing in RHEV manager provides:
1) Redundancy (provides failover protection).
2) Improved Performance which spreads I/O operations over the paths, by default in a round-robin fashion but also supports other methods including Asynchronous Logical Unit Access (ALUA). This applies to block devices (FC, iSCSI), although the equivalent functionality can be achieved with a sufficiently robust network setup for network attached storage.
