Small change in the updated whitepaper from HP and VMware vSphere 5 when using Round Robin multi-pathing policy (which is the recommended best practice. )
The old recommendation was to use IOPS=100, which has now changed to IOPS=1.
Make sure host persona 11 is selected!
Issue the following command on your ESXi host(s) that are being served storage from the 3PAR.
esxcli storage nmp satp rule add -s
-O iops=1 -c
