High performance interface bonding in Linux

My application:

I’m in the process of playing with DRBD with a couple spare servers in my garage. The idea being that while my business is far too poor to afford a SAN, a DRBD cluster should be able to exceed my needs for semi-redundant storage.

Part of DRBD involves a link between the two servers for synchronization (basically copying over bits that change). This is preferably a private link so that your primary connection doesn’t see bandwidth contention during heavy writes, so for testing purposes I tossed a couple dual port Intel NICs I had laying around into the servers so that I could have a dedicated 2 gbit synchronization link.
