Here's a spec to please the taste buds...
I've a customer who has been win4lining for a couple of years with great success. Their setup goes:
Windows PC. Cygwin. ssh -XCf --> Linux Box --> /bin/win (win4lin runs on remote box, X forwards back to the Windows PC.
They are looking at going from about 15 users to 80 users. This means a machine upgrade of sorts. I was wondering what sort of spec 'intel'-wise you would use to run:
80 users logged on using X windows. Forwarding to Windows PCs via SSH -XCf
Those users will all be running win4lin.
The windows app is a semi-intensive client/server arrangement that generally requires about 64Mb at least of RAM to run.
There is minimal requirement to access disk on that machine.
There would be major network traffic happening.
I would imagine that 80 ssh sessions would also generate a fair amount of CPU usage.
I'm thinking about the dual or quad operton processors from someone like SUN... Has to be x86 unfortunately. Any ideas? Beowolf clusters are not an option....
TIA

Are all 80 users going to be concurrent users? I've run 30 concurrent users in an LTSP environment satisfactorily off an x86 machine (1GB RAM and dual PIII). The main problem I found was disk access speed and the network connection was only 100MBit. The situation was such that the users were literally concurrent - it was a school with 2 classes logging on and doing exactly the same thing at exactly the same time. CPU was no problem really, nor RAM, although with an app needing 64MB per instance(?) I'd be getting as much RAM in there as it could hold to handle the app and the X session. I've got no specific suggestions apart from that. The server I was using was a HP server, which is still going.
