Summary:
Network Fault
tolerance is often overlooked. In High Availability Systems, this feature can
be of great utility as the downtime is zero in terms of Network connectivity
due to NIC failure.
NIC teaming is a new
feature of Windows Server 2012, which allows multiple network adapters to be
placed into a team for the purpose of providing network fault tolerance and
continuous availability.
When one of the network adapters fail, the other one
takes over without requiring third-party hardware or software. Windows Server
2012 NIC teaming is supported by any vendor’s network card but both are recommended to be identical, in terms of speed and vendor.
Windows Server 2012
supports NIC Teaming up to 32 Network Cards. Hyper-V supports only two.
