I know that VMware has MPIO capabilities with Fiber Channel but as I remember from VMware that this will be in there next release 4.0. There may be some discussion on how to do this with some ESX config but we don't know.
We know that Virtual Iron has this capability but there is some work that has to be done.
MPIO with let's say a MS initiator works well with 2 NIC's and separate subnets to one Target/LUN. We do not support multiple hosts connecting to the same target, you would need a SAN file system.
Is there a procedure for using MPIO with the MS iSCSI initiator (i.e. different subnets)? We have a customer who's trying it right now, and he needs help. Right now, he tried it using the same subnet and it's just using one NIC.
It is because name duplication problems. It can cause problems with access and domain connections especially when Windows based systems are present in the same subnetwork - even though the question is related to MPIO.
