Are you looking for some sort of high availablity? I have not done
anything like that but I do take daily snapshots of every box and then
archive those snapshots. If a box goes down it is an easy restore.

I do a couple of approaches, for the most part I bond the interfaces
together. That give maxamun throughput but I also have some KVM
machines that need their own interface so I have them. The bummer is
that the networking is not independent per box if they are clustered
so you need to make the networks look the same even though they may
not be.

Hope that helps,
