Scalable Storage Backends for Cloud, HPC and Global Science

Presentation

The CERNBox service is currently backed by 13PB of EOS storage distributed across more than 3,000 drives. EOS has proven to be a reliable and highly performing backend throughout. On the other hand, the CERN Storage Group also operates CephFS, which has been previously evaluated in combination with EOS as a potential solution for large scale physics data taking [1]. This work seeks to further...

25. Sync and Share Access to HPC Resources at CERN

Scalable Storage Backends for Cloud, HPC and Global Science

CERN Storage team has been experimenting with unified storage environments for HTC, HPC and interactive computing.

Practical examples at the prototyping and experimenting stage will be presented:
1. Easier access to user data in HPC storage (CEPHFS) via Sync/Share
2. Integration of HPC storage with the web-based analysis service environment
3. Open Source Storage backend synergy:...

33. The CERN Tape Archive : Archival Storage for Scientific Computing

Scalable Storage Backends for Cloud, HPC and Global Science

Presentation

The CERN Tape Archive (CTA) is the tape back-end to EOS disk. CTA went into production in June 2020 and currently stores around 400 Petabytes of physics data. During 2022, CTA will ramp up to full production data-taking volumes with the start of Run-3 of the Large Hadron Collider (LHC). CTA is an open-source system which is being evaluated and adopted by a number of scientific institutes...
