Amen to Asmo's post. My 2 cents: My modest setup consists of a server and exactly 4 thin clients. The server is a Xeon x3110 (C2D E8400 clone) 4GB RAM and a 3-drive RAID5 for /home. Clients are 100 mbit and server is 1000 mbit. Ubuntu 8.10 x86_64. My use-case is as bad as it gets. Being a youth drop-in centre, I have ~50 (4-simultaneous--duh) users mostly using youtube, addictinggames.com, amsn, or watching DVD rips, so lots of flash and lots of network traffic. The server doesn't break a sweat. I believe I could remove half the RAM and lock the CPU to 2 GHz and not see a performance hit. Purely conjecture now, if I tacked another 20 thin clients onto this network I expect it would fare well most of the time. 25 clients all on youtube or watching movies simultaneously would cause some problems, but even in this environment I can't imagine it happening. If you're not too budget restricted I would probably look at some quad-core setup with 8 GB of RAM, just to be safe. If you want lots of storage then build a RAID, but if not then consider a better-quality Intel or Indilinx SSD (or two). If money's a little tighter than that, then I expect you could get away with less, particularly if your client load will be lighter than mine. OpenOffice.org and casual web browsing on 25 clients won't bring a modern build on a GBE network to its knees. I'm not looking at upgrading the hardware any time soon, but when I do it will likely be swapping in an SSD or two in place of the drives in there now. Hope that helps. Have fun setting it up. db ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
