As it was mentioned in an earlier posting, let me add a couple of words on NAStore.

NAStore is a system to provide a Unix based, network connected file system with the
appearence of unlimited storage capacity.  The system was designed and developed at
NASA Ames Research Center for the Numerical Aerodynamic Simulation program.  The goal
was to provide seemingly unlimited file space via transparent archival (or migration)
of files to removable media (3480 tapes) in both robotic and manual handlers.  Supported
files sizes exceed the 2 gigabyte limit on most systems.  Archived data is restored
when accessed by the user with each byte being available as soon as it is restored rather
than having to wait for the whole file as is the case with other archival systems.

The NAStore system has been used here for 3 years and is under ongoing development.
It is based upon Amdahl's UTS and runs upon an Amdahl 5880.  We have 200 gigabytes of
on-line disk and 6 terabytes of robotic tape.

If your care for more information, let me suggest the following reading:
