I know it is almost impossible to say without knowing more information, but does anybody have any good "rule of thumb" numbers to expect for how many Citrix servers can be consolidated onto an ESX 3.x server? I have an ESX 3.0.2 Server with 16GB of RAM and 2 Quad Core CPU's with SAN Storage. We are going to run Vmware's Capacity Planner tool to get more information about the Citrix servers, but for now, how many normal Citrix Presentation Servers would you expect to be able to run as virtual machines on this hardware configuration? Just a guestimate would be fine for now... Thanks guys!
