Summary
Yes (FC, iSCSI)
Details
Multipathing in RHV provides:
1) Redundancy (provides failover protection).
2) Improved Performance (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.
RHV Manage Storage Connections feature (Multipath & DR) adds the ability to add/edit/delete storage connections to enable:
- Multipathing management
- Hardware changes
- Simpler failover to remote sites for array-based replication by quickly switching to work with another storage that holds a backup/sync of the contents of the current storage in case of primary storage failure
- Supports for the following storage types: NFS, Posix, local & iSCSI.
