Welcome to the DataManagement TWiki

Data Management Architecture Team

Mandate

Review
  • medium to long term evolution of data management s/w components now concentrated in DM group CASTOR, DPM, LFC, FTS, ...
  • possible architectural changes and prioritise them by their expected possible impact on scalability, deployment cost, s/w manageability

Driven by

  • LHC schedule and development resource constraints
  • commonalities between LHC experiment production models and emerging analysis models on the experiment side
  • existing (and possibly new) performance metrics from the running service
  • operational experience from deployment teams at CERN Tier 0 and its major partner sites

Meetings and Minutes

Documents and Presentations
