The more RAM the better, but we've found that 32 GB is sufficient for a 
standalone data server.  The more clients connected and request data, the 
slower the response from the Request JVM, but not to a degree to make the 
system unusable for a classroom (from what I've seen).

How many clients one server can handle is still undetermined, but from 
experience I've had roughly a dozen clients connected to a standalone server 
inside a campus network and the performance has been good.


> (3) - Is there any need for clients to be running AWIPS-II constantly, or can

No need for CAVE to run continuously, it can be easily stopped and restarted.
