CERN's EOS storage system, created for the extreme requirements of the LHC, now manages over seven billion files, ensuring seamless data handling for high-energy physics and beyond.
The Prévessin Data Centre, inaugurated in 2024, significantly boosts CERN's storage and processing capacity, supporting the Worldwide LHC Computing Grid (WLCG) with advanced infrastructure.
CERN's use of magnetic tapes for long-term data storage ensures the preservation and continuous migration of vast quantities of data to newer, higher-density technologies.
The introduction of the CERN Tape Archive (CTA) and new tape libraries enhances CERN's ability to manage and archive the increasing data volumes from LHC experiments.
The Meyrin Data Centre remains the hub for data collection, copy, and dispatching, connected to all experimental sites via an ultra-fast optical fiber network.
