[K12OSN] Server sizing in the real world

[David Trask]

My server(s)....4 GB RAM....dual 36 GB SCSI HD's (15,000 RPM) dual Xeon
2.x ghz...dual gigabit....works fantastic...can be built for about
2000-2500....or bought (Daktech.com) for $2900-ish.  Awesome machine...I
have several...make sure to ask for normal Intel gig cards and  NOT the
marvell yukon one.

This will server (very well) the amount of terminals you're talking about.
 I ran a server like this or a little less....for the past couple of
years...now that our deployment has grown...we now have two running in
dhcp failover/load-balancing mode (which by the way is awesome)....
