Re: [K12OSN] LTSP for 200 clients



Rule of thumb - 50 mb RAM per concurrent client. You can get by with less, but then disk performance becomes critical (swap). The fastest disk is still a few orders of magnitude slower than the slowest RAM.

Disk space should be fine; processing power is dependent on what apps that you plan on running, and how many diverse apps. As UNIX apps are re-entrant (multiple consurrent users from the same application on disk and in memory), then the fewer apps you run, the better performance is going to be. Even so, more users will increase processor demand.

If you can spare a 3rd box, something not to "heavy" (166 mhz Pentium, minimal ram and disk) to use as a firewall, that will free up a {very} little processor requirements, but makes admin easier.

Providing your network is solid and not all 200 of them are accessing at
once...should be OK I think
