Take a look at Tscale (http://www.rtosoft.com). It will pay for itself and then some by increasing your servers user capacity. In my experience about 35% more capacity or getting 4 server capacity with only 3 servers is my rule of thumb. If you are estimating 7 servers you could get by with as few as 5. A nice bonus is some apps will run noticeably faster. >>> Miguel-Guzman@xxxxxxx 9/24/2003 10:52:14 AM >>> Hello, Currently I am running 17 Win NT TSE servers w/2GB or RAM; these servers will go to their knees when they get to the 40 user count. I have been told to get us NEW servers so we all finally agreed to purchase ProLiant BL20p G2 X3.06-512 Dual Processor Blade servers with 4GB of RAM. I am going through a brainstorm here trying to figure out how many servers to ask for... The average user takes up form 24MB to 45MB of RAM per session; and we would like to be able to always have an off-line server or at least if one fails to not decrease the users performance. So far I have counted 1 server for CSG & NFuse, 1 server for STA, and 7 MetaFrame XP Win 2003 servers. Does this seem like a good amount?
