I have a simple question. What should I set the LAG to on the Dell (2,3, 2/3) and the Windows 2012 R2 team (static, dynamic, LACP), (address hash)?
The 2848 only supports static lag, so that is the option you should use.
Yes that is the best option unless you are using hyper-v guests.
Guest is the same as VM. Is everything running in VMs? http://blogs.technet.com/b/keithmayer/archive/2012/10/16/nic-teaming-in-windows-server-2012-do-i-nee...
