69. ATLAS Community Talk

Dimitrios Christidis (CERN)

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.

66. Data Challenge 2027

Katy Ellis (Science and Technology Facilities Council STFC (GB))

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...

71. FTS in Rubin Data Transfers

Wei Yang (SLAC National Accelerator Laboratory (US))

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,...

64. FTS Status and Future Plan at IHEP

Xuantong Zhang (Institute of High Enegry Physics, Chinese Academy of Sciences (CN))

IHEP operates FTS3 as a key data transfer service for several high-energy physics experiments, including JUNO, HERD, and other related projects. This talk will report the current status of the FTS3 deployment at IHEP and summarize its use in production data transfer workflows.

We will share operational experience from deployment, maintenance, and troubleshooting, including issues observed...

70. LHCb <3 FTS[34]

Christophe Haen (CERN)

I promise I'll update the abstract with a better title/description :-)

72. Operating Data Movement at SKA Scale: Progress and Future Directions for SRCNet

James William Walder (Science and Technology Facilities Council STFC (GB))

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...

62. Operational Evolution of the Fermilab FTS3 Service for non-CMS experiments: Modernizing Deployment, Automation, and Elastic Operations

Lorena Lobato Pardavila (Fermi National Accelerator Lab. (US))

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...

68. Rucio Project Talk

Dimitrios Christidis (CERN)

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...
