Redundancy for NIC

[kyisoethin]

Hi
I want to implement for redundancy of Network interface card of my server.
How can having two NIC for one pc be implemented for redundancy.
I have heard nic teaming work for that.What about for linux?
And how to implement that for both window and linux.
Thank a lot

You have to have a switch that supports link aggregation. If you want to go to two switches, you need much more.

Be really careful chasing redundancy. You need to look at the likelihood of failure and the complexity of the solution. Many times you will actually get more failures because of configuration issues in the redundancy than from the original thing you were trying to protect from. Nic or cable failure is extremely rare.

For servers the software is the most likely failure point but if you generically look at a server failure the solution most times a separate redundant server. When you have redundant servers you do not have to harden the servers as much. If you get any form of failure you just switch servers so you don't worry about solving all the low incidence failure mode and just switch servers if any occur.
