Re: [school-discuss] ltsp server specs question




Thanks to all for all these great answers. The guy buying the box jumped and bought it rather than trying to change the specs, but, in general, it's ok. Your comments reminded me of the old rule: more RAM is better.Â

more ram means more power draw... ÂI would think more ram is good when it is needed, but if it is not needed it gets in the way. Â for instance... Âyou do not need 8gb ram on a 3inch touchscreen phone.

But we're going with the middle estimates first. Hopefully, we'll be able to report nice performance. We'll see. I've done this before, but ten years agao, so I needed an update and the comments have been very useful. We've been following them up. The box is already bought; we're going with LTSP for now. It's a file server on the LAN, of course.Â


I am confused... Âisn't LTSP for clients? Â Â yet you say it is intended as a fileserver... Âthen I wonder... Âwhy do you need a full server if it is simple to share files? Â Âhow about something like the Sheevaplug Âhttp://en.wikipedia.org/wiki/SheevaPlug

Â

Its use is standard k-12 school, Tim. It's heavy on the Web and the main thing is usable file sharing via NFS.


so it seems you need filesharing and webserving? Â Â I was going to suggest a NAS solution... Â Âbut it seems your needs are more complex.. Âhttp://www.freenas.org/

Best wishes,

David

I think a more important way to go is to explain what the use of the server will be. Â Âyou mention 50 clients.. Â so please tell us what those clients will access on the server. Â Since you say only 25% at a time I can immediately cross out the potential that they are thin clients, yet it still leaves us guessing... Â what is the intended use of the server... ÂÂ

what type of box is this server to be housed in? Âwill it run 24/7? Â Â etc...

Dear Schoolforge,

If you have experience with ltsp, would you comment on the following specs for a new server for a small school (50 clients and another possible 100 laptops ... usually only 25% of those on-line).

DA SPECS:

CPU I5-2400 Â Â Â Â Â Â Â Â 3y warranty
MB asus p8z68-v lx   Â3y
RAM 4GB Â Â Â Â Â Â Â Â Â Â LT
Power Supply 850W Â Â Â5y
two 500GB HDs 7200RPM
no dvd drive
no graphics card, onboard graphics only

We're asking because this page is a bit old:
