Re: [SLUG] Mega X machine spec - ideas?
If you're doing Linux and want to put up with some non 64-bit apps, I'd recommend Opteron 2xx or better, running Fedora x86-64/Win4Lin and NX server. This way, clients don't need to know squat in order to connect cause the NX client is much easier to install and configure than Cywin. And yes, I've done it both ways, prefer NX by a long shot. www.nomachine.com Rowling, Jill wrote: Yes, a Sun SMP hardware with x86 card(s) might do the job. The main feature would be a very fast TCP stack, with the x86 part handled by the cards. You could always have it looked-at in something like the Sun iForce centre or the Securedata Fishbowl (if they still exist - Securedata got taken over recently I think by Dimension Data). Linux should run OK on the SMP box but I'm not sure if they have ported their x86 processor switching to Linux. Might have to be Solaris. Either way you will need a fair bit of RAM and maybe a couple of SPARC CPUs. Last time I used an x86 offload engine it was pretty slow. Another option is to go Opteron, which will emulate x86. Anyway, talk to them, not to me - I have not dealt with any of the above companies for anything like what you want.

Beowolf clusters are not an option TIA Stuart Guthrie 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.

RE: [SLUG] Mega X machine spec - ideas?
You probably want to use "sar" or the like on your existing machine to get a baseline understanding of CPU/disk/network etc. Hopefully you can extrapolate requirements from that. If the application onf the server is particularly critical you might want to consider using a hardware loadbalancer to front a server farm with a pair or more servers. This will give redundancy as well allow you to scale as performance requires it. You could even consider using blade servers if space/managability is an issue.
