Subject: Re: [Ltsp-discuss] hardware demands for Server when having 160
client computers?
I would say: certainly not one big server. I don't have a lot of experience
either, but you don't want all your eggs in one bag. I read an article where
they wired two classrooms to one server on one network with the server on
another network for intra- and internet access. I think such a setup makes
sense. Maybe you could have 6 servers and create 3 LANs. 1 for two classrooms
another for two other classrooms and a third for 3 (smaller) classrooms. Each
LAN would get 2 servers for redundancy and load balancing. This way you would
end up with 4 separate LANs. (Of course I would use 10/100 switches for them.
3COM has some nice 16 port switches for more or less 30 EUR) The servers
would sit on the school LAN on one NIC and on the TS LAN on the other side.
Somewhere else I read that multiprocessor machines don't age gracefully, so I
would go for Pentium III, Pentium IV or AMD servers with lots of memory (>512
MB) and quick disks. Maybe a RAID5 array of SCSI disks? You should test
performance with one such LAN subnet and see if you are happy with it.
You also have to think about where to put the user's home directories. Maybe
on yet another server on the central LAN?
I hope I haven't been talking too much nonsense here... The other people on
the list will surely correct me if I'm exaggerating :)
Greetings,
Jo
