Further, LANL supports university efforts that have helped develop pNFS [6],
a parallel NFS protocol, and Ceph [14], a parallel file system invented to
try out various scalability concepts (i.e., parallel file system metadata and
parallel file system security). Additionally, LANL has tried to be inclusive of
other agencies, like the Department of Defense (DOD), in the coordination
of efforts in the I/O and storage area. Finally, LANL continues to explore
various solutions in all areas of SAN, parallel file systems, middleware, and
parallel archives.
The I/O and storage strategy success at LANL varies with time, but in
general the principles that underlie the strategy are sound.
