Description

ANTARES (A New Tape ARchive for STFC) is the new tape archive service at RAL Tier-1 that went into production on 4th of March 2022. The service is built around the EOS/CTA technologies developed at CERN. EOS is the user facing service that manages the incoming namespace requests and a thin SSD buffer, and CTA is deployed as the tape back-end system. In this talk, we describe the setup of ANTARES and discuss the service’s performance as well as the main operational issues since the beginning of LHC Run-3. We discuss our experiences with the migration of LHC data from CASTOR, our previous tape storage system, and provide an overview of the expansion of the service to cover the whole of the high energy physics and astronomy community in the UK.
