Well.
Lets see what I have heard OF and what I have seen (not designs now, real
production)
Biggest I have ever SEEN was a 350 server farm. Larger environment than that
(many farms) but that was the biggest single farm in the org.
Next largest was about 250, then a 200. those are the top 3 as farm as
single farm size.
Largest on PAPER (vapor farms) 450. Again farms not total environment.

"How's the performance on a zone with 255 servers?"
It depends who you ask. Citrix says it's great.
I have a funny story about this.. (It's Wed, right?) I was an HP employee
promoting one of my books at iForum two years ago. Some guy came up to me at
the HP booth and said "Hey, I was in one of the sessions, and they said
there was no limit to the number of servers in a zone, and in your book here
on page xxx you say that there's a practical limit of about 100 or 125.. so
what's the deal?"
I gave my standard answer about how Citrix says what they say to make their
products sound good, and I say how things work in the real world. I also
told him that I didn't come out and say there's a limit of 125, but instead
I talked about how you determine the limit, and that tends to work out to be
about 125...
Anyway, as I'm saying this, the guy's iForum badge falls out of his
pocket--and it's white, meaning he's a Citrix employee!! It turned out that
it was this guy from Citrix Test Engineering who was "deeply concerned that
my book was providing misinformation to the Citrix community." (Then they
accused me of just copying everything from my book out of the Advanced
Concepts Guide.)
Long story short, since I worked for HP and HP is Citrix's biggest hardware
partner, I was told that I had to get everything I write approved by Citrix
(through HP) before it's published.
Oh, did I mention I'm self-employed now! :-)
Back to the point, today's hardware is so fast that you can easily run more
than 255 servers off a single zone. However, like TS server sizing, this is
also highly dependent on how the data collectors are used. (Number of apps,
number of users, number of logons/logoffs/disconnects/reconnects, etc, etc.)

That is interesting. I always used a server of 100 for each zone in a farm
as a standard rule. We can get 255 servers per zone. How is the
performance on a zone with 255 servers?

If memory serves.. the default limit for a ZONE is 255 servers, although you
can change that in the registry.
With the later versions of MetaFrame XP, you can set up the folders and
stuff in the CMC, and that really speeds things up since all the servers
don't have to refresh all the time.

I ment the biggest farm, but may be interesting the biggest Citrix
installation too...
Is there any limit in CMC (or in FR3 MC) about quantity of handled servers?
For example: it can handle only 255 servers...
