Description
LHCb's participation in LCG's Service Challenge 3 involves testing the bulk data
transfer infrastructure developed to allow high bandwidth distribution of data across
the grid in accordance with the computing model. To enable reliable bulk replication
of data, LHCb's DIRAC system has been integrated with gLite's File Transfer Service
middleware component to make use of dedicated network links between LHCb computing
centres. DIRAC's Data Management tools previously allowed the replication,
registration and deletion of files on the grid. For SC3 supplementary functionality
has been added to allow bulk replication of data (using FTS) and efficient mass
registration to the LFC replica catalog.
Provisional performance results have shown that the system developed can meet the
expected data replication rate required by the computing model in 2007. This paper
details the experience and results of integration and utilisation of DIRAC with the
SC3 transfer machinery.
