The Institute of High Energy Physics undertakes many large scientific engineering projects in China. These large scientific projects generate a large amount of data every year and require a computing platform for analysis and processing.
EOS is one of the main storage system at IHEP since 2016. The EOS instance at IHEP has currently a gross capacity of 50 PB. Currently we have deployed 6...
The Joint Research Centre (JRC) of the European Commission is running the Big Data Analytics Platform (BDAP) to enable the JRC projects to store, process, and analyze a wide range of data. The platform evolved as a core service for JRC scientists to produce knowledge and insights in support of EU policy making.
EOS is the main storage system of the BDAP for scientific data. It is in...
The EOS system serving as a grid storage element at IHEP, CAS started since 2021, working for JUNO experiment. A CTA with its EOS SE buffer also started its service for JUNO since 2023. In this talk, we would like to share our experiences and thoughts about the SE operations, including deployment, monitoring, data transfer performance, authentication management with VOMS and Sci-token,...

Computational storage involves integrating compute resources with storage devices or systems to enable data processing within the storage device. This approach reduces data movement, enhances processing efficiency, and reduces costs. To facilitate in-situ data processing on storage servers, we developed a computational storage plugin that can be added to EOS FST. This plugin enables users to...
In 2022 the CMS Tier-2 at Purdue University migrated its 10PB storage system from HDFS to EOS. Here we report on the details of the process, the difficulties we encountered and the ways in which we solved them. We also report on the current status of the storage system, and our future plans.
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.
The LPC cluster is a 4500-core user analysis cluster with 13 PB of EOS storage. The LPC cluster supports several hundred active CMS users at any given...
I will discuss our efforts to deploy EOS on Kubernetes at the University of Victoria T2 site for ATLAS, using a Helm chart and CephFS storage.
We present the current operation status of CDS (the Disk-based Custodial Storage) for ALICE experiment. The CDS is based on EOS Erasure Coding implementation with four parity mode to match with Tape based archival storage in terms of data protection. We will discuss briefly the plan of CDS operation automation for hardware intervention, especially the disk replacement, and of its expansion to...
2022 was a critical year which had some operational impact on all systems and services. In this talk we are going to present a few operational decisions, their implication on the EOS storage for the ALICE data taking and how we implemented mitigations by bringing improvements to the operations model as well as to the software stack.
