NIC teaming for SQL

Wanted to implement some fault tolerance and wanted to know if anyone of
you'll have implemented NIC teaming on your SQL servers ? If so, is there
any article on what it is and how to set it up ? Thanks>

You might find the following information useful:
Using Redundant Network Cards
To ensure that users can access the data center, use redundant network
interface cards (NICs), and use NIC teaming to provide automatic failover
between the NICs in the event of a failure. NIC teaming combines two or
more physical NICs into a single logical NIC, which ensures that the data
center always has an active link to the network. To use NIC teaming,
connect each NIC card to a different switch on a different subnet. NIC
teaming requires software from the NIC vendor, and each NIC is configured
to use a common virtual IP address. When all NICs are working properly,
their combined bandwidth is pooled for increased performance. When a teamed
NIC begins to fail, the software stops using the failing NIC and routes all
network communication over the remaining NIC or NICs. This failover process
is transparent to the operating system and other devices on the network.

Q. Is NIC teaming supported in a Server cluster?
A. Yes, however there are caveats. The use of NIC teaming on all cluster
networks concurrently is not supported. At least one of the cluster
networks that are enabled for internal communication between cluster nodes
must not be teamed. Typically, the un-teamed network is a private
interconnect dedicated to this type of communication. The use of NIC
teaming on other cluster networks is acceptable; however, if communication
problems occur on a teamed network, Microsoft Product Support Services may
require that teaming be disabled. If this action resolves the problem or
issue, then you must seek further assistance from the manufacturer of the
teaming solution.
