Antares: the first year in production

<!--HTML-->Antares 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. Finally, we provide an overview of the future plans for the expansion of the service to cover the whole of the high energy physics and astronomy community in the UK.
