Description
Data management components at CERN form the backbone for production and analysis activities of the experiments of the LHC accelerator. Significant data amounts (15PB/y) will need to be collected from the online systems, reconstructed and distributed to other sites participating in the Worlrdwide LHC computing Grid for further analysis. More recently also significant resources to support local analysis at CERN have been requested by several experiments, which poses additional requirements on the data management components, which have been extensively tested during the recent combined computing tests of the experiments.
In this contribution we report on the experience gained with the existing system and summarise the key requirements for supporting efficient end user analysis. We will describe the developments, which resulted in a first analysis system at CERN and will outline the steps to evolve this system together with the experiment and deployment requirements towards full LHC production phase. We will also outline the longer term vision towards modular data management components taking into account the expected medium term technology and media changes.
