1. The stateful inspection isn't the RAM -grabber, it's active caching.
2. ISA effectiveness isn't measured by RAM, although installing it over
W2KAS on 128MB RAM will drag its figurative butt across the carpet.
3. For that amount of traffic:
Single 1GHz proc
768MB RAM for caching support;
calculation: 256MB (base) + (128MB + (.5M * users)) = 584MB, round up
to next 128MB for room in the overhead
Drives (LVD-160 SCSI, of course):
1 9GB system drive
1 18GB cache drive (keep them separated if you like your hair)

2nd one means a huge cost blowout if you want them centrally managed...
i.e. you will need Enterprise.
Company I am with doesn't really believe in failover... we just back
things up... yes I know that sucks, but they are cheap asses... which is
why we didn't go Firewall-1 ;-)
The number of clients will be about 400... but with low usage. As long
as I can still set up the security using NT/AD groups, then the
standalone will be fine.
As for hardware... what are we talking about?
I was looking at a rack mounted Compaq DL?? with a 1G PIII and either
512MB of Ram, or more if needed... also probably about 36G of disk.
With the stateful inspection, I have heard you need more Ram the more
effective you want that to be... is that true?
PS... Thanx Jim for your help...
