The supported configuration for the AX4 is failover mode 1 (active/passive) - there is no mode 4 (ALUA). When you use failover mode 1 and are running ESX, EMC/VMware only support MRU on the hosts.
That said, RR might work. If you do use RR, you should look at the IO Operations Limit configuration setting - the default is 1000, you can get better performance using 1 - Google "IO Operations Limit". Be aware that we can not support this configuration as it has not been qualified.
