The sizing documents I've seen have been based on full desktop sessions, not running a remote desktop in kiosk (CAM) mode. When logging in using GNOME/JDS, the amount of RAM used just for your desktop is staggering. I checked it once, and if I remember can again tomorrow (Solaris 10 1/06 installation). I sure hope Sun upgrades to the current release of GNOME soon, as the memory management optimizations are an incredible improvement. The amount of RAM used by rdesktop was only about 15M per user, with the Connector being similar (if I remember correctly). With that in mind, you should be able to run considerably more users if you are not using Connector in a local desktop, and are instead running only the Connector in full screen CAM mode.
It also depends heavily on what your users are doing on these desktops... a few people trying to watch movie trailers can really kill the performance for everyone else. ;) You didn't mention how big your user base is. If it looks like you'll need more than the one dual-proc AMD box... you might want to look at a T1000. With a 4-core (16 thread) T2000 running Citrix ICA client in kiosk mode and about 8 users (very early stages here), sar (with 5 minute granularity) shows idle time never dropping below 97% - even during peak usage. This is wonderful, as we plan on adding more than an order of magnitude to this count. I mention the T1000 as it is cheaper and the bottom end model has a higher-end 6-core (24 thread) CPU. Counting the cores, the T series can compete pretty well with the AMD lines. Since you are using the Connector, your choices are broader. If you have any chance of going to Citrix, be aware that they haven't updated their Solaris x86 client in many, many years... SPARC only for Citrix on Solaris. I can't comment on the windows side... except the speculation that the 200 users must be just playing winmine (solitaire would likely be too much load). ;) Of course - I don't speak for my employer - in fact I haven't even disclosed my employer.

Guys, Need your opinion about sizing Sunray Server with CAM using Windows Connector. Also sizing for Terminal Services. I have very strange calculation right now. Sun Ray Server (2 CPU 8 GB) can handle 40 concurent user (Sun Documentation), but in Other hand Terminal Service (2 CPU 8 GB) can handle 200 concurent user (HP - Microsoft Documentation). I know there is something wrong about this calculation but I can not find any document to prove. Based on any experience, how should it be since it would be very strange that sun ray server need bigger machine than the processing unit (Terminal Service). I prefer to use Opteron based server sizing for sunray server and terminal service since I have to compete to $600 PC.
