Tests of the Federated ATLAS XrootD system with HammerCloud — •Federica Legger, Guenter Duckeck, Johannes Elmsheuser, and Friedrich Hoenig — Ludwig-Maximilians-Universitaet Muenchen

The HammerCloud framework was developed to ensure the smooth operation of the ATLAS Grid infrastructure through the automatic validation of the site capability to execute both analysis and production jobs, and to test specific issues such as the validation of new sites, performance evaluation after hardware changes, and testing new software releases and configurations. In particular, HammerCloud has been extensively used to test the Federated ATLAS XrootD system (FAX), a storage federation aiming to treat Tier-1, Tier-2 and Tier-3 storage space as a single distributed storage system. We report on the results of such tests, aiming to evaluate the efficiency, use cases, and possible limitations of the FAX infrastructure.
