For starters, Proxy Server 2.0 is NOT an enterprise solution. I have my
reservations to whether NT is, but I will not spew that on you as well. I
have spoken to MS about MS Proxy, and they still have not been able to
give me difinitive numbers (it has been 2 months now). I realize the type
of traffic, and the size of the box make a big difference, but MS
themselves state on their site that you should have one proxy per 2000
desktops. Others I have spoken too about MS Proxy say it's REAL limit
per box is more like 300 users. Microsoft themselves use 16 of their
proxies for about 45000 users (at least this was the last number they gave
me). I doubt there really is a good answer for the actual capacity of an
MS Proxy, but I personally opted for CSM Proxy strictly from a scalability
perspective. Let me also note that I put my proxy servers BEHIND a real
firewall as well.
You have to look at possible growth, current needs, future needs, is your
business becoming more web-centric? What are you trying to acheive? I
chose my proxy solution based on 3 needs: User authentication (so logging
was not done by IP only since we are DHCP), use the NT user database
natively, local cacheing to both increase perceived responsiveness and
reduce load on our internet T1. I also have to consider the possibility
of corporate policy change that could take me from 2000 users currently to
something like 25000 users overnight. Given your needs, you may arrive at
different conclusions. I needed something that could at least limp along
as is without adding several boxes immediately (I have 2 dual 450 compaq
3000's each with 4 9gig drives and 2 gigs of ram. With the two, CSM can
easily handle the potential load).
