couple questions...

[Ricardo Kleemann]

Let me try to picture it...

I'm horrible with ascii art... :-(

I guess we can look at it as a mini cluster with 4 servers. Servers A and B 
are application servers. Servers X and Y are database servers.


                    A
                 (LVS)
                     |
               --------
               |          |
              X ---- Y
               |          |
               --------
                    |
                (LVS)
                    B

X and Y are redundant, replicated database servers. Both A and B would have 
their database connections load-balanced between X and Y.

So I was wondering if simply running LVS on BOTH server A and B, in order to 
achieve the load balancing, is feasible.

In this case, the LVS is really directing local connections (on A or B) to 
the X/Y servers. It is not directing external connections from the internet.
