EOS software evolution enabling LHC Run 3 / Caffy, Cedric (CERN) ; Amadio, Guilherme (CERN) ; Guenther, Jaroslav (CERN) ; Lekshmanan, Abhishek (CERN) ; Mascetti, Luca (CERN) ; Peters, Andreas (CERN) ; Reis, Manuel (CERN) ; Simon, Michal Kamil (CERN) ; Sindrilaru, Elvin (CERN) ; Smith, David (CERN)
EOS has been the main storage system at CERN for more than a decade, continuously improving in order to meet the ever evolving requirements of the LHC experiments and the whole physics user community. In order to satisfy the demands of LHC Run-3, in terms of storage performance and tradeoff between cost and capacity, EOS was enhanced with a set of new functionalities and features that we will detail in this paper.First of all, we describe the use of erasure coded layouts in a large-scale deployment which enables an efficient use of available storage capacity, while at the same time providing end-users with better throughput when accessing their data.

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 Administrators / Davis, Michael (speaker) (CERN) ; Sindrilaru, Elvin Alin (speaker) (CERN) ; Peters, Andreas Joachim (speaker) (CERN)
In this seminar we will go through the architecture of EOS, showcase some EOS instanace configuration and follow with an introduction to CTA! We will explain some generic concepts, deployment models, hardware requirements, redundancy models, storage layout, scheduling & file placement - CPU, Storage and Network requirements and few tricks to optimize these. We highlight in detail the XRootD framework and how EOS is implemented using it. [...]

EOS for Users - how to use the CERN physics storage system most effectively / Valverde Cameselle, Roberto (speaker) (CERN) ; Mascetti, Luca (speaker) (CERN) ; Sindrilaru, Elvin Alin (speaker) (CERN) ; Peters, Andreas Joachim (speaker) (CERN)
The IT storage group provides end-user access to a 700 PB disk storage system: CERN EOS. In this seminar we will explain your possibilities to use EOS storage as a CERN user most effectively for everyone! **Part 1 :** Dive into the EOS eco-system We will start with a brief introduction: *How is the EOS service deployed and segmented? How do you get access to EOS storage and how you can authenticate to the service?* We will explain the various access interfaces: - Command line access using the shell - Using EOS as a filesystem /eos/ - Remote access protocols root:// and https:// - Accessing EOS from applications like ROOT, C++, Python … - The CERNBox web interface *You will learn, how you share access to files, folders or subtrees with your colleagues, how the permission systems of EOS and CERNBox interact, how you get an EOS drive on your Mac, Linux or Windows computer, how you can verify your quota, how you can understand where you use most of your space, how you can access EOS from outside CERN, what are the best access method for applications and many more useful hints for your daily work.* We will finish with a short list of features, which are configured to mitigate user errors and service downtimes: -Service & Data high-availability model -Backup system -File Versioning -Undo Deletion using the EOS recycle bin *If you deleted all your files, how can you get them back? Can you?* **Part 2:** Running workflows using EOS storage This part will cover best practices for running interactive and batch workflows using EOS storage with few examples on a laptop/desktop, lxplus, the batch farm etc. *What can you do to get efficient data access and what you should never do! How can you authenticate from GITLAB to EOS?* We will also briefly give some insights, how EOS service managers might influence or change your access to EOS..
