The CernVM File System (CVMFS) provides the software distribution backbone for High Energy and Nuclear Physics experiments and many other scientific communities in the form of a globally available, shared, read-only filesystem. However recently, CVMFS has found major adoption beyond academia: in particular Jump Trading, an algorithmic and high-frequency trading firm, now uses CVMFS for...
CERN Storage and Data Management group is responsible for ensuring that all data produced by physics experiments at CERN is safely stored and reliably accessible by the user community. 2023 Run-3 and especially the Heavy Ion Run have pushed further the previous records in terms of data volume and transfer rates delivered by the main LHC experiments. The targets anticipated by the data...
Despite of the growing number of flash-based data storage systems the usage of spinning disks (HDDs) for large on-line data storage systems is still advantageous. Measurements of the read-write behaviour of a cluster file system using external storage controllers backed by HDDs are presented. Contrary to commonly expected balanced read and write rates, resp., or even read rates slightly...
Most data center data is stored on hard drives. But can they compete in the future, and what is the role and future of hard drives and the different hard drive technologies available? The challenge is efficiently scaling storage infrastructure while optimizing for write/read performance, TCO, and sustainability goals.
In this session, we will explore how areal density and the latest hard...
The Euregio Meuse-Rhine border region between Belgium, the Netherlands and Germany is a potential site for the Einstein Telescope. In late October of 2023 Nikhef was asked to organise a backup and archiving of seismic survey data. This talk covers how the seismic data was then being shared and not backed up. The quick fix to backup the existing data; some custom python code being used as a...
CERNBox is an innovative scientific collaboration platform, built using solely open-source components to meet the unique requirements of scientific workflows. Used at CERN for the last decade, the service satisfies the 35K users at CERN and seamlessly integrates with batch farms and Jupyter-based services.
Following the presentations given at the CS3 Workshop 2024[1] and CERN Storage...
ESS is getting ready for its next major milestone, which we call 'beam on dump,' where we will commission the full LINAC at the end of this year.
Although ESS is not yet completed, we have already built most of the IT infrastructure to support the control system for the accelerator, target, and neutron instruments.
System experts, operators, and beam physicists are already requesting to...
Data centers are at the forefront of managing vast amounts of data, relying on three primary storage mediums: Flash/SSD, Hard Drives, and Tape. This presentation deals with the special characteristics of the individual technologies and examines the question of whether the forthcoming advances will lead to one technology being displaced by the other. Central to our discussion is the examination...
