Xen users - Feb 2009 - Storage questions

Hello,

I am looking to set up a Xen array of servers and I don''t really know
how to
set up the storage subsystem.

I have been looking for a little while and two options stand out for my
setup. The problem is rather simple, I need a pool of servers to access a
shared storage ressource.

The first option is the easiest, NFS.

The second option is a little more complex in appearance. I won''t be
able to
have enough budget to buy a SAN so that is out of the question. What I could
do is have a storage server with a bunch of disks. I would GNBD (or some
other Network Block Driver) coupled with GFS. I am pretty new to these two
concepts. I know that GNBD cannot be used alone if I want more then a single
server to access the storage space.

What is more interesting with performance in mind ?

Thank you in advance for your input,

Antoine Benkemoun
