Topics

  • Federated access to data is one of the main recommendations of the Data Management and Storage TEG.
  • For the large scale implementation it is important that several technical details and policies have to be clarified, agreed and documented, so that implementation and setup can progress.

Mandate

  • Clarify in detail which forms of federated data access need to be supported
    • “fail over” for individual jobs/“repair mechanism” of placed data/who initiates the repair?/how is metadata handled?/pro-active repair?
  • Work on relevant aspects of federated data stores
    • access control and trust mechanism between sites
    • use of catalogues
    • etc.
  • Suggest a deployment and operations model for the additional components
    • redirectors
    • xrootd plugins for non-native systems
    • experiment specific configurations/plugins
    • configuration of federations
    • discovery of federations
