Achieve what?

Aha, ok suggestion for the deploy of LVS with DR:

o you load balance your web and mail server in the
  first tier.
o you load balance with a second NIC but same LB in
  a separate net the database server for requests 
  from the webservers over their backinterface.
o get the HA software from and some
  replication software to keep your db sync'd.

Basically I only talk for myself but I think you just
try to setup/design the system and ask specific questions
in this list. For your setup there is nothing I could
think of that would not be solvable so go for it and
start it and when you're stuck you ask the specific 
questions and I'm sure someone on this list will already
have solved the problem and will certainly give you 
the correct advice. 

However, I'd offer you to draw the 2 Tier architecture
design with the LVS so you get an idea how you could
make your network setup as HA as possible.
HTH and best regards,
