Network Port Usage

I'm wondering if someone had a better idea for what I'm trying to do. I have a small cluster of beefy Hyper-V servers.  Each server has 20 1GB ports.  This is my approach to port usage for the NICs:
  • 20 ports
  •    4 ports - iSCSI multi-pathing
  •    4 ports - VM DMZ Network Team
  •    12 ports - LAN
  •           2 - Server Management Team
  •           2 - Cluster Heartbeat Team
  •           8 - VM LAN Network Team
That would normally be sufficient; however, I want to present iSCSI LUNs to virtual machines directly without putting iSCSI traffic on our LAN switches. My thoughts were to take two NICs from the VM LAN Network team and connect them to our iSCSI switches then create two separate Hyper-V networks for those NICs.  Then I would add two additional NICs to the virtual machines that I need direct storage for.  Does anyone know of a more elegant solution?

Thanks. We'll let you know when a new response is added.

In Windows 2008 R2 clustering really doesn’t need it’s own heartbeat network any more. I’d use those for guest iSCSI traffic.
