Abstract

With the increase of storage needs at the High-Luminosity LHC horizon, data management and access will be very challenging. The evaluation of possible solutions within the WLCG Data Organization, Management and Access (DOMA) is a major activity to select the most optimal from the experiment and site point of views. Four teams hosting Tier-2s for ATLAS with storage based on DPM technology have put their expertise and computing infrastructures in common to build a testbed hosting a DPM federated storage called FR-ALPES. This note describes the infrastructure put in place, its integration within the ATLAS Grid infrastructure and presents the first results.
