VNXe3200 High Availability Question
I am using the VNXe3200 to serve up NFS datastores to my 3 ESXi 5.5 hosts.
In the document VNXe3200 High Availability - A detailed review it shows setting up SP A and SP B on different subnets in the NFS configuration details. My question is why? How does using different subnets help HA as opposed to two different IP's on the same subnet? I currently have eth2 and eth3 aggragated using LACP and two different LAG groups in the switch, but both on the same subnet. Should I rethink this config?
Thanks for your help.

Having different subnet in that document is to show that, VNXe can handle network level high availability if one switch goes down.
If your network got sufficient HA, you dont need to reconfigure the subnets (like you can have mutiple switches interlinked).
