my p2000 has dual controllers each with (2) iSCSI ports. I have (2) open NICs on each of my (2) ESX hosts. is there any benefit to running them through switches (two switches on separate subnets) rather than just connecting directly between the hosts and the SAN? one host NIC to one p2000 controller and the other host NIC to the other p2000 controller, for redundancy of course. My current SANs (AX4-5i and a Promise VessRaid) run through these switches.
