We used to use Citrix XenApp server to deliver whole Windows
desktop to the Sun Rays. We dropped that last year in favor of Sun Ray
connector. In our testing the Sun Ray connector performed better
graphic and multi-media wise. Plus it's a big saving not having to
purchase all those Citrix licenses. Now there are couple of big loses
in dropping Citrix. Cirtrix load balancing is better, but so far the
Microsoft load balancing is working for us. Next big lose was USB
redirection. The Sun Ray connect doesn't suport USB redirection in
Window 2008 or up. That is of SRSS 4.2 which we are running. Maybe some
can comment whether USB redirection is working in the latest release of
The other fact with Citrix, is that it has to run a whole bunch of
other crap processes with takes away resources from each of your
terminal servers, and ultimately the number of users you can put on each
server. With Sun Ray connector there are no other extra processes
running on your terminal servers.
