And in fact, for those who did not read further on the NAS website, 
Columbia is no longer the prime compute resource at the NASA Advanced 
Supercomputing Division at NASA Ames Research Center.  C/XFS are no 
longer the primary filesystems used by the main compute resource.  CXFS 
simply can't scale to the client node count and bandwidth of the 
Pleiades cluster--it wasn't designed to.  Columbia had 20 fat nodes of 
512 CPUs each, 20 CXFS clients.  Pleiades has 10,752 thin nodes.  The 
only suitable production filesystem for such a high node count compute 
cluster machine is the Lustre cluster filesystem, specifically designed 
for large node count clusters.
