[LUG] Server to Server Network link bonding with two or more NICs

 

Hi folks,

A couple of years ago when working for a local radio station I came across Link Aggregation to bond two gigabit network links to a switch to give double the bandwidth and a bit of redundancy if a link went down.

Recently I've been thinking about how to get faster than 1 Gigabit Ethernet without having to go down the fibre route and I wondered if it was possible to do link aggregation or bonding with just network cards.

What I'm thinking is two Linux boxes with 2 or more Gigabit NICs connected with cables between them and no switch and having them talk to each other at 2 Gigabit (or more depending if more cards are added).

Does anyone know if this is possible or would it require a switch?

Rob
