RAID is handled transparently in Debian. http://www.freedomtoaster.org/?q=node/72 gives us the specification but that doesn't mean it has to be according to the specs. Remember this is a machine that shoule be actually *whatever* we can afford. Plenty of RAM, Hard disk, Internet, and a good set of CD/DVD writer should do for now (All these stuff can be get if someone authorative figure from foss nepal can contact NGOs/KU/other organisations for donated hardware). Where are all the KU guys. All i hear talking in this mailing list are fossian regulars. Bipin: if you are worried about raid levels, http://xtronics.com/reference/SATA-RAID-debian-for-2.6.html, aka the mdadm software handles raid0-12 on SATA devices on debian. Let's not worry too much about implementation at this stage. The important thing to worry are IMO - 1. How to get those commodity parts. 2. Setup FT hardware team. 3. Setup FT software team. 4. Internet problem. There could be more. Another note, Manish Regmi ji also showed interest in it so please welcome him! :) Cheers. --~--~---------~--~----~------------~-------~--~----~ FOSS Nepal mailing list [email protected] http://groups.google.com/group/foss-nepal Community website: http://www.fossnepal.org/ -~----------~----~----~----~------~----~------~--~---
