LVS with 3 Servers questions

[Nguyen Kinh Luan <luan@xxxxxxxxxxxxx>]

Hi all,

i´ve read nearly the complete avilable documentation at 
www.linuxvirtualserver.org and www.ultramonkey.org but didn´t found the 
answer...
This is what i want to setup:

I need a HA and Load-Balance solution for a high traffic website (~50Gig 
and ~10 million requests per day).
I have 3 servers for this purpose. Two of the servers are Dual-Xeons and 
one is a P4 2,4Ghz. These servers are rented and hosted by a well 
connected provider.
I think the major problem is that every server has only one NIC and one 
IP address. Additionally every server runs in its own subnet :-(
Is there any chance to setup a LVS system under these conditions ? My 
plan would be to use the single CPU machine as the load-balancer and the 
two dual-CPUs as the real servers for apache. NAT is not desired, 
because the traffic should also be balanced between the real servers. In 
other words, if the clients make requests to the site the real servers 
should deliver for themselves the pages without passing the traffic back 
to the load-balancer.
Maybe this graph can help:

                    Client
                       |
                       |    --> request page
                       |        

                 Single-CPU LB (1 NIC, 1 IP e.g. 82.134.21.3)
                        |
                 -------|-----
                 |           |
                 |           |
                Dual        Dual (both Duals have also 1 NIC, 1 IP)
             217.12.31.2   217.67.23.239


If HA is not possible maybe just load-balacing ? Maybe something like 
the Streamline setup from ultramonkey.org ?

thanks for your tips/help,
Luan
