DPM storage support is gradually declining and it will be discontinued in the coming years. Computing sites with this grid storage must decide what to use as their future storage technology and each migration strategy comes with different requirements for site administrator expertise, operational effort and expected downtime. We will describe the dCache migration tool distributed with the...
INFN CNAF is the National Center of INFN (National Institute for Nuclear Physics) for research and development in the field of information technologies applied to high energies physics experiments. CNAF hosts the largest INFN data center, which also includes a WLCG Tier1 site.
We describe the technologies adopted at CNAF for Data Management and Data Transfer, namely XrootD and StoRM (with its...
CERNBox aims to bring the ease of a file sync and share service to scientific data processing at CERN. It provides a simple and uniform way to access over 15PB of research, administrative and engineering data across more than 2 billion files.
In this contribution we report on our experience and the challenges of taking an upstream sync and share service (ownCloud) and integrating it into...
The CERN IT Storage group operates multiple distributed storage systems to support all CERN data storage requirements. Among these requirements, the storage and distribution of physics data generated by LHC and non-LHC experiments is one of the biggest challenges the group has to take on during Run-3.
EOS, the CERN distributed disk storage system is playing a key role in LHC data-taking....
In an attempt to stress test and gauge the throughput potentialof the new XRootD fronted CEPHFS storage element at the Lancaster WLCG Tier 2 a large scale atlas transfer of 100TB of data was initiated. This volume of data was pushed to the site over a period of 3 days and revealed unexpected bottlenecks and problems - of which raw network bandwidth was not one of them. The most notable issue...
Part of the mission of the Scientific Data and Computing Center (SDCC) at Brookhaven National Laboratory is to provide access to storage service to a diverse range of HEP scientific experiments, e.g, LHC-ATLAS, Belle2, DUNE. An aggregate of 122M files and data storage of 76PBs is distributed and managed by independent storage instances for each VO. The underlying technology used to support...
With the release of 4.0 dCache offers its transfer logs in form of a Kafka message stream. Since then the DESY dCache operations team has made heavy use of these for the monitoring of our installations as well as analytics in general. However, it has so far not been used for any of our production services.
On of our instances provides the underlying storage for our NextCloud instance. The way...
BNL recently implemented an efficient staging system between dCache and the backend HPSS tape storage. The system has three modules: the Endit Provider Plugin originated from NDGF, the ENDIT HPSSRetriever developed by BNL, and the optimized BNL’s HPSS Batch (ERADAT) system. This solution addresses performance bottlenecks in staging identified during the WLCG tape challenges. The system...
