Dirac

The Dirac system has been the long-term storage and archive system for the NCCS for many years. Dirac runs the SGI Data Migration Facility (DMF) to manage data.

The NCCS archive has been named Dirac for many years in honor of the Physicist Paul Dirac who won the Nobel prize with Erwin Schrodinger in 1933.
