multiple subnets per VLAN and port binding

Hi,

I need some clarification.

Our iSCSI SAN storage (Dell MD3660i0 requires a separate subnet per port.

We require multipathing and load balancing in VMware.

To achieve this in ESXi 5.1 we need port binding...BUT port binding is only supported if the vmks are all in the SAME broadcast domain accorrding to these two KBs

VMware KB: Considerations for using software iSCSI port binding in ESX/ESXi

VMware KB: When using multiple VMkernel ports with port binding to access two or more storage arrays on different br…

Ok...surely then I can simply put all my ISCSI storage subnets in one VLAN and all will be ok (a VLAN is after all a broadcast domain, both are L2 stuff)..this would satisfy the KBs requirements....if VMware really mean 'broadcast domain' in the true sense of the term.

So my question is can you configure port binding in this way? Is it supported by VMware?
