Description
The MADDEN project aims to enable seamless data access and sharing across multiple Research Infrastructures (RIs) by developing a Multi-RI Data Lake based on Rucio. As part of the project, production and test Rucio servers were deployed for the Einstein Telescope, with three Rucio Storage Elements (RSEs) located at INFN Torino, UCLouvain, and PIC. The RSEs at INFN Torino and UCLouvain are managed using XRootD. In addition, mock Cosmic Explorer Rucio infrastructures were deployed with production and test servers and two XRootD-managed RSEs at INFN Torino and UCLouvain. FTS is currently integrated into both the production and test Einstein Telescope infrastructures and is being configured for the mock Cosmic Explorer test environment. The production Einstein Telescope Rucio infrastructure also participated in the XRidge 2026 Data Challenge, providing an opportunity to evaluate the deployed services in a realistic data-transfer scenario. This contribution presents the architecture, deployment experience, and current status of XRootD and FTS within the MADDEN Multi-RI Data Lake.
