Description
Within 5 years CMS expects to be managing many tens of petabytes of data in tens of
sites around the world. This represents more than orderof magnitude increase in data
volume over existing HEP experiments. This presentation will describe the underlying
concepts and architecture of the CMS model for distributed data management, including
connections to the new CMS Event Data Model. The technical descriptions of the main
data management components for dataset bookkeeping, data location and file access
will be presented. In addition we will present our first experience in using the
system in preparation for a CMS data challenge in summer 2006.
