I am running a Dual Pentium III 733MHz Dell with 2GB of RAM. Our user's file
systems are mounted via NFS on a Netware box. We have about 300 potential
users and right now about 25 on at a time. We are adding terminals and X
windows servers to Windoze machines so that usage will be climbing.
One interesting thing. This summer we had a lab with 18 terminals all running
on a 10M hub. They got very heavy usage and the hub did NOT seem to be a
limiting factor. It's now a switch, but the hub didn't seem to be a problem.
I can also tell you that our RAM usage never comes close to 2GB. I am using a
smaller footprint window manager called ICEWM.
I will be adding another server sometime this year and will be glad to have all
our storage and authentication centralized. Which reminds me.....
....gotta get back to work on those backups :-)
