I have a Windows 2008 Hyper-V servers running in a 2 node cluster and Cluster Shared Volumes.
I have one nic assigned to my primary network.
I have one nic assigned to an iSCSI Lun to my Netapp Appliance.
Is it best practice to assign my 3rd nic to an iSCSI Lun for my quorum disk?
Can I assign my 4th nic to my Hyper-V virtual machines I create on the server?
Can the nic I assign to my Hyper-V virtual machines be on the same subnet as my primary nic?
I.E.  172.44.16.45  and 172.44.16.50?

Is this best practices?

When you create a virtual network using Hyper-V manager, uncheck "Allow management operating system to share this network adapter". That will remove it from the cluster host, and it won't have an IP address. All of your VMs can then use that NIC.

Instead of trying to dedicate a NIC to your CSV and another NIC to the disk quorum, you should use MPIO to connect to all of your iSCSI volumes using two NICs. That is standard good practice. I am not familiar with NetApp, but they do have an MPIO package that you need to pay for, so you may or may not have it. Otherwise just install the Microsoft MPIO package.
