A multi-purpose computing center: FNAL

The Fermilab Computing Center is described with a special emphasis given to the scientific computing systems and the data storage and archiving systems. The scope and focus of this paper is the Fermilab scientific computing facility. It does not cover, or does not cover very well, related issues such as data Grids, cloud computing and storage, commercial storage, data integrity, authorization, access rates, and novel storage technologies. These are all important considerations in discussing data centers and should be kept in mind when one explores issues related to computing centers and long-term data storage.
