ATLAS has relied on FTS to transfer millions of files across the Grid every single day. When a preproduction FTS4 instance was made available to ATLAS, we enthusiastically assisted with its testing. This talk will focus on our testing methodology, observations, and conclusions.

This CERN Openlab Summer Student project aimed to benchmark and compare different storage solutions used or considered for CERN's computing infrastructure. The main goal was to evaluate a Pure Storage appliance, HDD/SSD baselines, and CERN's production storage systems, including CephFS, XRootD and EOS. The benchmarking methodology relied on [Flexible I/O (FIO)][1] scripts designed to...

The WLCG Data Challenge series drives change and performance improvements in our data movement systems, required in time for the start of the High-Luminosity LHC (HL-LHC). Following challenges in 2021 and 2024, this talk describes the planning in progress for the challenge in 2027, expected to take place near the start of the year. The four LHC experiments plan to take part, alongside others...

Rubin/LSST is using the Rucio/FTS/Xrootd/dCache ecosystem for data transfer and distribution between their Fr/UK/US data facilities and independent data access centers around the world. Here we will outline the integration of Rubin's native data management system Butler and the Rucio ecosystem. We will focus on Rubin's specific challenge of efficiently transferring large number of small files,...

Contemporary research relies heavily on computational resources and storage, with data sharing serving as a critical element. Data access remains a central challenge. The Open Science Data Federation (OSDF) project aims to establish a global scientific data distribution network by leveraging the Pelican Platform and the National Research Platform (NRP). OSDF is based on the XRootD and Pelican...

SRCNet provides the international data movement infrastructure for the SKA Regional Centre (SRC) network, connecting geographically distributed facilities that will store, distribute, and process SKA science data. As SKAO approaches operations, validating reliable, high-throughput, and scalable data transfer services becomes a critical challenge.
This talk presents the current status of...

We present the operational evolution of the Fermilab FTS3 for non-CMS experiments, highlighting the modernization of its Kubernetes deployment, adoption of GitOps-based automation, and migration to a more maintainable infrastructure. We discuss the introduction of elastic scaling, improved monitoring, and lessons learned from operating FTS3 in production to enhance the reliability and...

The vast majority of scientific collaborations employing Rucio for their data-management needs choose FTS to orchestrate their site-to-site transfers. The two projects have collaborated closely over the years. This talk aims to cover a variety of topics, such as the migration to FTS4, the scaling for the Data Challenge 2027, and OAuth tokens. It will also mention Rucio’s current plans for...

Going back in time by about 30 years or more, the CERNLIB library was used by a large number of experiments and collaborations, across a huge number of platforms and architectures. Written (mostly) in C and Fortran, it contained a large number of highly optimized tools, among them the "Physics Analysis Workstation (PAW)", a popular tool to visualize scientific data at the time, and the...

OpenVerify is an XRootD OFS plugin that probes candidate replicas before the client is redirected. It can locate via CMS Rucio with cmsd fallback, quarantine unhealthy sites, and export Prometheus metrics to reduce federated open failures on missing or broken files.

This presentation provides an operational overview of the XRootD services hosted at Fermilab, including the USCMS AAA regional and FNAL site redirectors, as well as the StashCache redirector supporting the OSG Data Federation. We summarize the current deployment architecture, service monitoring, and operational practices.
