Backup NIC

Hi,
I'm setting up a new server and I need it to have a backup NIC so that if
one fails the computer and IP address revert to using the backup one.
Ideally I would like to load balance between these NICs having them both
running simultaneously on the same IP but I don't think this is possible.

Hi Andrew,

What you are describing is NIC teaming.NLB does not work like NIC teaming,

Network Load Balancing Frequently Asked Questions

Q. Can NLB Be Used Instead of NIC Teaming Software to Provide Adapter Fault
Tolerance or Increase Throughput?
A. No, NLB cannot be used to “team” adapters, i.e., group adapter ports
together. NLB is used strictly to load balance traffic among multiple hosts
in a load-balanced cluster.

Are you also applying fault-tolerant thinking to other components in the
server, such as --

* power supply
* fans
* hard drives
* CPU
* RAM

In my experience working in large data centers with thousands of servers,
NICs are some of the most reliable things you can put in a computer. Failure
rate was on the order of a few thousandths of one percent. We spent waaay
too much money on teaming and never recouped that investement.

Power supplies, fans, and hard drives are the things you really need to
worry about: they're mechanical and they will die. Redundancy there makes
sense. Elsewhere it seems rarely useful.
