Ubuntu Thin Client : help needed at a Tibetan school in India

[Glen Merrick]

Probably one of the best ways to run a thin client is to run
DRBL(http://drbl.sourceforge.net/).  If your motherboards support network
booting set the boot order to be from the nic.

I would suggest that you would want something with as much power and ram and
hard drive space as you can afford.  A dual/dual AMD Opeteron would work
with at least 2GBs of ram per processor die, so 4GB in the system,
consisting of 4 1GB dimms in dual channel mode (if you can afford more,
great).  Minimum hard drive space should be on the order of 1 250GB (min)
drive holding /root and the other partitions (not including /home or /swap).
A second separate smaller drive (40GB, 80GB) drive on another channel for
/swap because of the lack of memeory on your client computers. For /home a 4
drive raid assembly with 500Gb drives for /home for redundancy.  If a raid
array is not feasable, then 1 500GB drive for /home.  Finally, I would
suggest a 750Gb drive for A.M.A.N.D.A. to dump backups to before writing to
tape, and pick up some sort of secondary backup method.  IF you cannot
afford a tape drive and the accompanying tapes, then a $1500 to $2000 NAS
device should do the trick.  That price range will get you a NAS device with
4 bays that will hold a standard HD which is upgradable in the future to
whatever the largest capacity out there holds (1TB is coming soon)

I would suggest that you upgrade the 128Mb ram to whatever the maximum is
for those computers to minimize network traffic.  Kingston ram is always a
favourite of mine because of their lifetime warrenty and you can always find
out from their website what ram will work on almost every motherboard out
there. 

As with everything else, optimal configuration ultimately depends on what
you can afford.

Hi all,

I am writing from Tibetan Children's Village School, Dharamsala (H.P.),
India.  We have decided to introduce Gnu/Linux for our students in class VI
and VII and gradually migrating to Gnu/Linux in phase wise. The
configurations of the computers are Celeron 1.5GHz, Intel motherboard, 128SD
RAM, 52xCDROM, 15" Color Monitor. We have 30 computers and all the computers
are networked.

I want to implement Ubuntu thin client for the lab to simplify management,
configuration, software distribution, anti-virus fight. etc. 
etc. Could someone suggest what CPU and what size of RAM, Hard disk would we
need for the Server machine for the 30 computers.

Thanks!
