At KIT we operate HPSS as a tape system for the GridKa WLCG Tier-1 and for the Baden-Württemberg Data Archive service. Performance limitations of the HPSS disk cache systems led us to explore new technology options for the disk cache, based on classic storage systems with SSDs, storage servers with local NVMe devices, and also options based on IBM Storage Scale. We will present details on the...
And overview of changes coming with the Efficient Nordic Dcache Interface to TSM (ENDIT) 2.0, reasoning why, and performance plots from benchmarking and production.
China’s High Energy Photon Source (HEPS), the first national high-energy synchrotron radiation light source and soon one of the world’s brightest fourth-generation synchrotron radiation facilities, is being under intense construction in Beijing’s Huairou District, and will be completed in 2025. The 14 beamlines for the phase I of HEPS will produces more than 300PB/year raw data. Efficiently...
Ceph is a popular software defined storage system providing an open source alternative to proprietary appliances and cloud storage. It provides block and object storage for on-premises clouds as well as networked filesystems for shared compute facilities including several WLCG sites. Altogether, Ceph aims to be a single solution to all of our data centre storage needs -- the "Linux of...
The RAL Scientific Computing Department provides support for several large experimental facilities. These include, among others, the ISIS neutron spallation source, the Diamond X-Ray Synchrotron, the Rosalind Franklin Institute, and the RAL Central Laser Facility. We use several Ceph storage clusters to support the diverse requirements of these users.
These include Deneb, a petabyte-scale...
