Windows 2012 MPIO
We have 2 HP DL 380 Gen 8 servers with windows 2012 installed on each of them.
Each server has four NIC's . We are setting up a HyperV cluster. Out of the 4 NIC's, 2 NICs would be teamed for VM traffic. one NIC and ISCSI traffic and one NIC for heartbeat.
We are using HP P2000 as shared storage . On HP P2000 4 NIC are plugged to the iSCSI vlan.
So my question is do I need to install MPIO's on the windows 2012 servers. I thinking as we are using just one NIC on each server for iSCSI traffic we don't need to.

if you are going to cluster, the minimum required is 8 physical network interfaces
2 - VM Network Traffic
2 - iSCSI (MPIO)

Thanks Guys
@ hanccocka
Can you provide any MS documentation about the minimum cluster requirements showing that we need 8 NICs

if this is a production system, you will really want to team for resilience, to reduce single points of failure - this is recommended.

Thanks Hanccocka
Just want to confirm that we don't need to use MPIO when using single niC on the HYperV server even when we have 4 NIcs from the SAN on the iSCSI network

No requirement for MPIO on a single NIC.
MPIO is for more than one nic.

So on the SAN out of the 4 iscsi NIC if one of them fails will the hosts still be able to access the data

So you still need MPIO on the server even when using a single NIC

Virtualization
Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

But I would recommend, you use at least two nics, install MPIO, and you will have resilience, and increased throughput to your iSCSI SAN.
Also ensure you enable Jumbo Frames on your network interfaces, network switches, and SAN.
