Just my two cents worth... we used to run ALL services off of two servers when we first started out in the ISP industry....now we have 26 CORE servers running critical services... some of the decision depends on your size.... The thing we really like about running so many servers is that if one server happens to go down that doesn't have fault tolerance, then big deal.... our dial-up users can still surf, our websites are still online or whatever the case may be.... If you move to a few BIG servers with RAID5, dual fault tolerant power supplies etc.... that's great.. but what happens if you take a box down my mistake (software glitch whatever)... it's happened the best sys admin's out there.... oops! Time to reboot... while you're rebooting your whole operation if offline or a good majority of it... Personally, I just did this the other day... I was downing an IP address (virtual web account) as the customer now wants Front Page extensions which is on a seperate server... instead of downing the IP itself, I took down the entire ethernet for that server.... dumb mistake but it happens... however instead of taking down ALL our web customers at that moment, I only took down about 200.... :) If we had all web customers on one server, then more people would have been yelling.... thankfully either way, the server was only down for about 30-45 seconds.. but even so...
