[Beowulf] Poor man's SANS

PVFS2 (http://www.pvfs.org/pvfs2) is my favorite option for this :).  My
group at ANL along with Clemson University and Ohio Supercomputer Center
and others are developing this.  It's entirely open source and open
development, and is in production use at ANL, OSC, and the University of 
Utah CHPC, among other places.

GFS (http://www.redhat.com/software/rha/gfs/) is another; I believe that
RPMs are available for it now through one source or another.  This used to 
be Sistina's product, who was subsequently bought by RedHat.  I'm sure 
this is used in production in many business environments, and we use it at 
ANL also.  Can someone provide a URL for this one?

Lustre (www.lustre.org) is another option.  This one is heavily funded by
the DOE ASC laboratories and is in use on some very large parallel
machines.  But unless you have a relationship with CFS you can only get a
crippled version of the source, so it's probably not a good option for
average joe.  If they change their policy on releasing source code, this 
would be worth reconsidering.
