I have a 3 node Server 2012 Hyper-V cluster that I'm working through setting up. Each node has 8 NICS. I'm currently doing this:
NIC 1 Management LAN
NIC 2 Cluster Shared Volume
NIC 3 Live Migration
NIC 4 iSCSI /MPIO
NIC 5 iSCSI /MPIO
NIC 6 Virtual Switch - Teamed
NIC 7 Virtual Switch - Teamed
NIC 8 Virtual Switch - Teamed
I'm starting to wonder if I should move the Live Migration to the CSV network and add another iSCSI connection to the SAN such as:
NIC 1 Management LAN
NIC 2 Cluster Shared Volume / Live Migration
NIC 3 iSCSI /MPIO
NIC 4 iSCSI /MPIO
NIC 5 iSCSI /MPIO
NIC 6 Virtual Switch - Teamed
NIC 7 Virtual Switch - Teamed
NIC 8 Virtual Switch - Teamed
It's also important to mention the SAN arrays have 2 connections each to the switch, not three. So perhaps adding a third connection to the server nodes wouldn't have a tangible benefit because the SAN only has so much bandwidth anyway.
I'm interested in opinions on this, thank you!
