Here is a little more insight into what I envision to
be the core network.
Hopefully this will help in the scalability question I'm desperate to get a
better understanding of.
I'm just not sure if I've under-engineered this, or over-engineered it - and
what I can get rid of to save money or what more I need to spend.
I don't know about sems, but ser, if tuned for performance can do
4500-4800 cps on a dual athlon mp 2000+. On your configuration (dual
Xeon 3Ghz 1Mb cache) it should do much better (but I think it is very
improbable to have 10000 calls in a second from 100000 users, at least
not sustained more then a few seconds). You might consider adding more
memory (4Gb so you can use 3-3.5Gb for ser). This only if you want to
be prepared for the worse (DOS attacks that try to initiate as many
calls possible to non-responding destination, creating a lot of
transaction that will be deleted only after the final response timer
hits (default 120s); ser uses about 5k/transaction ).

Thanks again for all the help!

Architecture = Intel i386
Bandwidth = DS3 to OC12
Population Size = Initially, a 100k user base at 10-1 ratio (10,000
simultaneous calls) and a 100-1 ratio for voicemail (1,000 simultaneous
calls).
Scenario Implemented:
2x centralized database servers (For SER/SEMS) Running Redhat Advanced
Server 2.1 - Quad 2.5Ghz 1MB Cache Xeon CPUs - 8GB Ram - 60GB Raid Storage
on host - Multi-Threaded MySQL - Multiple Gigabit Network Interfaces
2x centralized storage servers (For VM, Web Content, etc) Running Redhat
Advanced Server 2.1 - 2GB Ram - 140GB Storage on Host - 2.04TB Raid Storage
- Multiple Gigabit Network Interfaces
4x SER servers Running RedHat AS 2.1 or RedHat 9 - Dual 3Ghz Xeon CPUs per
server - 2GB RAM - NFS to Storage Server via Deticated Gigabit Network -
Seperate Network card for Internet Connectivity - 18GB Raid Storage on Host
4x SEMS servers Running RedHat AS 2.1 or RedHat 9 - Dual 3Ghz Xeon CPUs per
server - 2GB RAM - NFS to Storage Server via Deticated Gigabit Network -
Seperate Network card for Internet Connectivity - 18GB Raid Storage on Host
6x WEB Servers
3x DNS Servers

No, it depends on many factors like, architecture used, bandwitdth,
population size, scenario implemented and so on.
