Hey,
Each host had 2 pNics hence used 2 nics per controller head. vSwitch configured with recommended active/unused fashion pNics. This is approach is in most documentation at the moment. No LACP or etherchanel on pSwitch side so redundancy is used by native vmware MPIO software. Each Nic on the same controller has to be in different subnet so group Nics in same subnet from each controller. Each pNic would then be on these resepctive subnets. ALUA SATP and PSP would be supported from the firmware versions mentioned. I also used RR algorithm to share load and changed IOP's threshold to 8 from 1000 (this can be changed on the fly). Should use two switches for network redundancy as well. Hope this helps...
