Operation of the CERN disk storage infrastructure during LHC Run-3 / Caffy, Cedric (CERN) ; Amadio, Guilherme (CERN) ; Rios, Maria Arsuaga (CERN) ; Reis, Manuel Batalha (CERN) ; Capitoni, Niccolo (CERN) ; Contescu, Cristian (CERN) ; Guenther, Jaroslav (CERN) ; Mascetti, Luca (CERN) ; Peters, Andreas (CERN) ; Sindrilaru, Elvin (CERN) et al.
The CERN IT Storage group operates multiple distributed storage systems to support all CERN data storage 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 LHC Run-3.EOS [1], the CERN distributed disk storage system is playing a key role in LHC data-taking.

EOS for ALICE O2 - Evolution and challenges (2022 - 2023) / Contescu, Cristian (speaker) (CERN)
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..

LHC Data Storage: Preparing for the Challenges of Run-3 / Arsuaga-Rios, Maria (CERN) ; Bahyl, Vladimír (CERN) ; Batalha, Manuel (CERN) ; Caffy, Cédric (CERN) ; Cano, Eric (CERN) ; Capitoni, Niccolo (CERN) ; Contescu, Cristian (CERN) ; Davis, Michael (CERN) ; Alvarez, David Fernandez (CERN) ; Guenther, Jaroslav (CERN) et al.
The CERN IT Storage Group ensures the symbiotic development and operations of storage and data transfer services for all CERN physics data, in particular the data generated by the four LHC experiments (ALICE, ATLAS, CMS and LHCb).In order to accomplish the objectives of the next run of the LHC (Run-3), the Storage Group has undertaken a thorough analysis of the experiments’ requirements, matching them to the appropriate storage and data transfer solutions, and undergoing a rigorous programme of testing to identify and solve any issues before the start of Run-3.In this paper, we present the main challenges presented by each of the four LHC experiments. We describe their workflows, in particular how they communicate with and use the key components provided by the Storage Group: the EOS disk storage system; its archival back-end, the CERN Tape Archive (CTA); and the File Transfer Service (FTS).

Data flowing on the Stream / Contescu, Cristian (speaker) (CERN)
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 going to detail in this talk..

CERN Disk Storage Services: Report from last data taking, evolution and future outlook towards Exabyte-scale storage / Mascetti, Luca (CERN) ; Rios, Maria Arsuaga (CERN) ; Bocchi, Enrico (CERN) ; Vicente, Joao Calado (CERN) ; Cheong, Belinda Chan Kwok (CERN) ; Castro, Diogo (CERN) ; Collet, Julien (CERN) ; Contescu, Cristian (CERN) ; Labrador, Hugo Gonzalez (CERN) ; Iven, Jan (CERN) et al.
The CERN IT Storage group operates multiple distributed storage systems to support all CERN data storage requirements: the physics data generated by LHC and non-LHC experiments; object and file storage for infrastructure services; block storage for the CERN cloud system; filesystems for general use and specialized HPC clusters; content distribution filesystem for software distribution and condition databases; and sync&share; cloud storage for end-user files. The total integrated capacity of these systems exceeds 0.6 Exabyte.Large-scale experiment data taking has been supported by EOS and CASTOR for the last 10+ years. [...]
