+1.

I think Nanar proposed to get a external raid array ( as we do have for
zarb.org ) so this could help ( check with him, and the price of array
we can place inside ).

I would also check with Lost Oasis people about space we still have in
the rack, as we are sharing everything with zarb.org for now, and this
could place some constraint in term of size, and I fear that "lots of
disk" could mean "take lots of space".

Also, we need a estimation of what we need : 
- databases
- svn dump
- ldap dump

Do we backup everything at Marseille datacenter, or everything ?
IE, blogs dbs are already taken care thanks to dams, but for the sake of
simplicity maybe having a single procedure would be better. And this
would be a issue for more remote db like forums, etc.

How many ? 1 per server, more ? Raid, non raid ?

Also, do we have proper support on iurt to achieve that ( ie, each job
with its own disk, or some low level trick to achieve that ) ?

I would propose to try to not be shy and try 3 builder per server, at
least on jonund, so maybe put more disk there ?

Also do we still have slots ?

The board indeed doesn't have disk, and to be fair, I am not sure about
connectivity for that, likely USB
( http://pandaboard.org/content/resources/references ). I will try to
get it and drop it at mageia pub^W secret headquarters :p

Something that would be nice is some kind of case, but I do not have
anything nor much idea on how to find one.

Speaking of this, as rtp has pretty good relation with efika ( *khof*
smartbook *khof* ), maybe he could arrange for stuff like that :

For the last item, I would propose we try to get a server from ovh.
Mandrivafr did it and they weren't too constraining about conditions.

Alternatively, maybe Dedibox can provide us another one ( raphael spoke
about it, having a 2nd rabbit would fit nicely to offer vms to test
packages ). 

We could also arrange this server to have a public http server
( people.$domain ), either in a vm or on the main server.
