LHC Data Storage: RUN 3 Data Taking Commissioning
Update on the setup and operations at the Vienna Tier-2 site.
Fermilab has been running an EOS instance since testing began in June 2012. By May 2013, before becoming production storage, there was 600TB allocated for EOS. Today, there is approximately 13PB of storage available in the EOS instance.
An update of our current experiences and challenges running an EOS instance for use by the Fermilab LHC Physics Center (LPC) computing cluster. The LPC...
As part of its storage migration plan, the CMS Tier-2 center at Purdue University is preparing an EOS deployment of ~10PB, which will serve as the main Storage Element of the site, as well as a basis for the future Analysis Facility that’s in development at the moment. We adopted a fully containerized approach with Kubernetes, which allows us to better share available hardware resources...
Due to the increasing interest on data management services capable to cope with very large data resources, allowing the future e-infrastructures to address the needs of the next generation extreme scale scientific experiments, the national center of INFN (Italian Institute for Nuclear Physics) dedicated to Research and Development on Information and Communication Technologies (CNAF) and the...
In this talk we will highlight the operational challenges we faced while bringing up a high-throughput EOS instance for the Run 3 ALICE data acquisition. The journey started in 2020 and we are still perfecting the instance to this day.
During this time all storage nodes got migrated from CentOS 7 to CentOS 8 and, later on, CentOS Stream 8, and not without inherent challenges which we are...
