4、 IBM Corporation6IBM TechXchange/2024 IBM CorporationMultipath Path Selection Policy on VMwareFIXED This policy uses a designated preferred path to access the storage device.If the preferred path becomes unavailable,ESXi switches to an alternative path.Once the preferred path is restored,ESXi will s

5、witch back to it.This policy is suitable when a specific path is known to be more efficient.MRU With the MRU policy,ESXi uses the path that was most recently active.If this path becomes unavailable,ESXi selects another path.It does not revert back to the original path if it becomes available again u

6、nless all other paths fail.Round Robin IOPS This policy cycles through all available paths,distributing the I/O load evenly across them.This can enhance performance by utilizing all paths concurrently.The Round Robin policy is often used for active-active storage arrays where all paths are equally c
