[K12OSN] odd question..

[Tony Hadfield]

Hey Norbert,
This sounds like a really interesting project. I have been digging around on
the subject of clustering and have some useful links. Tha article here
http://openmosix.sourceforge.net/ltsp-omr4-1.html
<http://openmosix.sourceforge.net/ltsp-omr4-1.html>  is about combining
OpenMosix clustering with K12LTSP. Its worth a read although the version of
K12LTSP he used is quite old. His idea was to use the clients spare
processing cycles to create the cluster rather than build the cluster out of
dedicated server hardware (such as the rack mounted beast you intend to
build). 
You will also probably find these useful:

Good luck and please keep us posted / let us know what you did.

I'd like to thank all those who responded with their great ideas.. :-) 

In order to promote K12ltsp in schools we want to "build" .. with the
participation of select students, a 75 node P-I  cluster and have it run
n-number of thin clients in the school that succeeds in getting it to work.
The winner will get the cluster & thin clients FREE to use in their school
or organisation. 
With this "stunt" we hope to raise the visibility of Linux & K12 in our
area, once done we'll invite press and school boards to see what Open Source
Systems can do !!!

So please keep the ideas and suggestions coming.

thanks
norbert

NB Just in case anyone has any doubts ..... YES we are nuts !!! :-D .......
but determined....

You could just take sheets of aluminum and make rack mounts for each 

board, drilling and tapping the sheet for the standoffs for the 

motherboards.



However, remember you will have to have power supplies for each board.



And you will have to leave sufficient room between boards for cards to 

stand up unless you use fully integrated motherboars (video, LAN, etc. . 

.)



Then there's the thing of cooling air.  the boards would have to be far 

enough apart for the cpu fans to get sufficient air.



But then again if you use the integrated boards, some of those fit into 

the slimline cases so that shouldn;t be a problem.



This is a good idea, but it will take a considerable amount of design and 

fab work to make it happen.  But if you already have the motherboards and 

power supplies and etc, it could be done reasonable inexpensively.

    



Doug briefly addresses cooling. I'm thinking, unless you mount the Mb's

sideways, you will want to not use a cage that is enclosed and cools by

sucking air up through it, but rather in the front and out the back or

some such type.



Sounds like a fun idea to mess with.
