EMC's recommendation would be install PowerPath/VE and set the mode to CLAROpt (CLARiiON Optimized) for your environment. You can refer to below Best Practices. [URL]
i created a new lun on a cx4-960. In vcenter it defaults to using mru as a multipath policy which shows 4 active path but 1 active path has I/O.  then i changed the policy to round robin and now it has 4 active paths and all 4 active paths shows I/O.  is this the prefereed config over mru if I dont have powerpath?
round robin mru
