On the other hand, Regarding equipment/software,
here's an old post from Steve Nelson that may
interest you.
This is the approach I will be taking: Multiple
inexpensive rackmounts. You pay more in software,
less in hardware.
I just got my first 512MB 733PIII IBM 7200rpm ATA/66 20GB HD
for $1500 (4U rackmount). Haven't had a chance to put
it in service yet. Seems pretty fast. Didn't even
bother to mirror the HD. Got a spare IBM HD for the whole
server farm.
best, paul

You can test your web apps with a load balancing application.
You simulate load, define bottlenecks, fix them, goto start.
Steve Nelson suggested this one:
http://homer.rte.microsoft.com/
A free app from Microsoft. I haven't used it yet,
though.
Good luck.
