Just thought I would put this out there for the benefit of those that are not aware that 2012E natively supports NIC Teaming.
Christian over at theaverageguy.tv tipped me off to this, so I had an old GB nic PCI card laying around so put it in the server, enabled it and set up a new "team" in server manager which was dead easy to do.
Now getting circa 450M/s read and writes between the server and other PCs on the network through a GB switch: Happy days
So for my money, a great way to get extra, usable performance out of your server for cheap. Give it a go.
