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
