Ron hit this right on the money. We have a comparably sized farm (approx. 150 servers and supporting approx. 7,500 users) and have our farm broken down into 3 zones. Our usage pattern is just as Ron mentioned (users log in in the morning and back in after lunch) and we don't have any communication issues. Thanks, Mason B.

Citrix says 100. But it will depend on the number of requests to the DataCollectors. SO lets say you have 200 hundred servers and 10,000 users. Your users only connect once or twice a day . Logon in the morning. Close their session at lunch and logon in the afternoon. The 75 server per zone would not be too bad. Very few requests to the DC. BUT lets say its all published apps. And users close and open apps all the time. Thus causing a DC request each time. Well about 50 per zone would work well. Its worked in my environments of comparable size.

A single zone is supossed to be too much load for the data collector as Citrix reports. Does anybody have any background to argue how many zones should be configured and why ?
