I am trying to determine how I should design my zen tree scenario. We are
a large school district, 25,000 end user machines. I read the hardware
requirements for the zen servers and middle tier servers, says 200
concurrent users per gig of ram. I am going with HP boxes with 12 gigs of
ram and dual 3.4 ghz xeons. The primary function for the zen tree is to
push out policies, workstation import and removal, and some app
distribution. There will be no use of imaging. I am looking for some
advice on how many servers I will need for the backend and the middle
tier servers. Any suggestions would be greatly appreciated.

Thanks in adavance.
