As a side note my quad port NIC came in today.  I want to put it in my file server, as I want to start restructuring my storage setup to be more like a SAN.  I already got a dedicated switch that I'll use for storage.  Debating on sticking to NFS or doing iSCSI. iSCSI gets more complicated if I want to do live migrations across hosts though as you need a cluster aware file system.  I want to eventually get off Vmware and do something like Proxmox.  I only have one host at the moment though, so really iSCSI would make more sense, then I can figure out what I want to do if ever I get a secondary host.  I don't really NEED HA or live migrations so I could simply not do it and just have LUNs that are dedicated for each host.
