The CERN IT-Storage group is responsible for the operations and the development of the infrastructure matching all the storage requirements from the physics data generated by LHC and non-LHC experiments to the personnel users’ files.

CERN IT operates the main storage resources for data taking and physics analysis mainly via three system: AFS, CASTOR and EOS. With the slow decline of AFS the department took the strategic decision to use EOS and CERNBox as the main replacement.

CERNBox is the CERN cloud synchronisation service for end-users allows syncing and sharing files on all major mobile and desktop platforms (Linux, Windows, macOS, Android, iOS) aiming to provide offline availability to any data stored in the CERN EOS infrastructure.

EOS, the high-performance CERN IT distributed storage for High-Energy Physics provides now more than 160PB of disks and a variety of data access protocols. It supports several work-flows from data-taking and reconstruction to physics analysis. With the next storage delivery the system will grow above the 250PB mark.

In this presentation I will give an overview of the solutions operated by the group with current and future storage developments. I will discuss about the strategy of the group to face future needs, highlighting the challenges ahead and the future evolution of the CERN Home directory service.

Luca Mascetti is a computer engineer in the CERN IT Storage group, in charge of operating and supporting the data storage system services for CERN and the WLCG (Worldwide LHC Computing Grid) communities. He is responsible for the deployment of the EOS storage system in production at CERN, service manager of multiple storage systems and currently responsible for the CERNBox project, the CERN sync & share solution.
