A great little piece on NIC teaming with Windows. Aidan Finn says his mind is changed now that it’s included in Windows Server 2012 and fully supported for Hyper-V and failover clustering.
True, MSFT hasn’t had NIC teaming and there’s a KB article which says they don’t support it. NIC teaming is something that the likes of HP, Dell, Intel and Broadcom provided using their software. If you had a problem, MSFT might ask you to remove it. And guess what, just about every networking issue I’ve heard on on Hyper-V was driver or NIC teaming related.
As a result, I’ve always recommended against NIC teaming using OEM software.
