Well, if I were running a 10000 user system, I'd want the redundancy for
reliability if nothing else....

What happened to the other 15%?

Robert Joly has been doing some performance testing of 3.11 (will be 4.0
soon), but those results are not ready yet.
The sizing of a system is very sensitive to what you're going to be
doing. How many calls will your 10000 users be making per unit time?
As I said above, CDRs add load - so do:
* Using reliable provisional responses (depends on how you
configure your phones and gateways)
* Monitoring the busy status of other phones (Busy Lamp Field).
If I were going to put together such a system today using 3.10.3, I'd
probably do two boxes like the one you have, but with double the memory.
I'd put two ethernet interfaces in each (bonded so that they are one IP
interface for each box) and put them on two switches with each box
connected to both switches and the switches connected to each other.
Then I'd simulate the load, or if I couldn't do that I'd put some users
on and measure how well I was doing and then migrate more in.
You can add a third system, or you could replace them with faster boxes
(I suspect that the former is actually more cost-effective).
