The system is slow, clunky, and the database is getting full, so we've been told to clean out our mailboxes because they're going to delete all mail older than 30 days. My question is this--does anyone have experience with a system that will scale reasonably to that many users. If so, we have about 90,000 students. Know of a system that will scale that big? The head IT guy tells me that he was quoted a commercial cost of between $250k and $500k for a system that would handle us, and, while that doesn't surprise me, I think something effective could be done much more economically. I'm just wondering if there's anything I can point to and say, see!

Nobody will listen to you, and anything you say will likely be discredited from that point on. Look for outside vendors that base their products on open source and can provide proven solutions with support.

The reason? What you just said--"large universities." Remember that universities have a decades-long tradition of running UNIX, way back from the late 1970's. UNIX (and thus GNU/Linux and BSD) is well entrenched in the minds of the support teams at universities. This is, remember, where they offer Ph. D. Computer Science degrees and have all sorts of other eggheadiness. K-12, unfortunately, ain't like that. Unlike major, prestigious universities who actually trust their IT departments (e. g. University of Michigan, University of Washington, MIT, UC Berkeley, and such), K-12 bosses are gonna go for "ooh, pretty package" over actual functionality any day. That's why they shouldn't be in charge of IT, but you know their egos. Go for "pretty package" based on Free Software and *actual* open standards. --TP </body> </html>
