Welcome to PhEDEx
The CMS experiment is managing hundreds petabytes of data recorded by the detector and simulated physics events. Data are transferred to computing centers, or sites, providing facilities for data storage and computing resources for data processing and analysis.
PhEDEx (Physics Experiment Data Export) maintains the knowledge of data replicas locations and manages data transfers between the CMS sites.
Main PhEDEx components are:
  • Central Transfer Management Database (TMDB) maintaining a system state
  • Agents performing central and local site-specific tasks
  • Interactive Web Page for managing and monitoring the transfers
  • Web data service providing APIs for integration with other tools
  • Command-line tools for the operations and administrative functions
