Yes you can have many public-side LVS VIP's on one
load balancer, but only one private-side NAT VIP.
(All of which failover in a heartbeat situation.)
These public-side VIP's are what you usually use to
distribute the load to two or more real servers.
However, if you want ftp or ssh direct to a specific
real server, you just setup a "fake" load balance of
one real server for that service/port (ftp, ssh). I do
that by adding one additional public-side "admin" VIP
for each real server behind the load balancer.
