[K12OSN] Server sizing in the real world

[Eric Brown]

I've got a Dell 6350 off ebay for under $500.  It's got a quad Pentium 550
MHz with 3gb ram.  You can still find them on e-bay for that price.  I even
say the next level up with a quad 800 MHz for not a whole lot more.  With my
server, I run 22 terminals without much trouble.  If you have the money to
spend, I'd go more.

Hope that helps.

Hi,

The school has changed plans (again!).

We were going to start with an old server and a few K12ltsp terminals in a
few classrooms to see how things worked out.  Now the school wants to use
the K12ltsp for a dedicated computer classroom with about 20 terminals.  My
guess is they will want to run other terminals in other classrooms off of
this server eventually.

They have found some money for a good server.   That makes it a lot 
easer cause the old server isn't really working well.

The hardware wiki talks about needing 250 meg for the server and 50 meg (or
more) per terminal.  Is this really enough for Gnome/OpenOffice/Tux type/Tux
math/etc.?  What sort of experiences have you had with the number of
terminals per server?

Bottom line: can a single server handle 35-50 clients?  How much memory and
hard drive would be enough?

Many thanks,
Barry
