We're using a single LVS server to balance things out to 4 webserver, 2
POP mail and 2 SMTP mail servers. Actually, it's 3 webservers right now,
as a hardware failure required us to steal a webserver for 'other uses'

All of the servers behind the LVS are netbooting from an NFS machine. 

This sucks because we have a single point of failure (LVS) but the
intent is to get a second eLViS (hehe) running with heartbeat between
the two. It's on the network map ;)

So you can run it with a single LVS, but I wouldn't prefer to. Since
it's simply redirecting stuff, it doesnt' need to be that powerful.
