Description
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 projects. Characterizing the performance boundaries of the Pelican Platform under various configurations, such as transfer rate limits, buffer settings, and geographic distribution, is essential. To this end, OSDF access was systematically profiled globally. The evaluation considered multiple file sizes, parallel data streams, and diverse client-server geographic relationships. This approach facilitates comprehensive monitoring of XRootD and Pelican performance across a range of scenarios. Results indicate that OSDF can deliver transfer speeds approaching the maximum capabilities of client systems.
