Until just over a month ago, I had a system in place serving 25 terminals. It was found out, after two years of trouble-free operation, and ripped out for "not being Windows." It worked very well for that load and had some room to spare; the last K12LTSP version that it ran was 4.2.1, which I find that I like a lot, even though 4.4.1 is out. Here were the specs of that server. Twin AMD Athlon 1.47GHz chips 4GB DRAM Two 80GB parallel IDE disk drives (started with just one) Gig-E fiber NIC You'll notice that I used parallel IDE disk drives, while Petre recommends SCSI disks. He's right; SCSI is certainly better than any form of ATA. However, it does cost more to implement. When the above server was built, we were in a tight-budget situation and thus went with parallel IDE so that we could build the server at all (I just flat refused to do it without 4GB DRAM). The server not only served 25 LTSP terminals, but also acted as a major "Windows" file server for the school, thanks to Samba. It handled everything thrown at it with aplomb. --TP On Wed, 2005-10-12 at 14:52 -0500, Petre Scheie wrote: <BLOCKQUOTE TYPE=CITE> <PRE> Quick & dirty reply: For 35-50 users I'd get a dual-CPU box with 4GB RAM and a pair of SCSI disks, at least 36GB, 72GB if you can afford it. Get gigabit NICs for the server and make sure your switch has gigabit ports for the server (the clients will be fine with 100Mb ports). That should be enough to cover you for a while. As you add more clients over time, you can look into getting another server and splitting the load, or using dedicated application servers for heavy apps like OOo.
