Description

With the start of the Large Hardron Collider at CERN, end of 2007, the associated experiments will feed the major share of their data into the dCache Storage Element technology at most of the Tier I centers and many of the Tier IIs including the larger sites. For a project, not having its center of gravity at CERN, and receiving contributions from various loosely coupled sites in Europe and the US, this is certainly an organizational and financial challenge. The presentation is meant to be the comprehensive overview of the numerous sub-projects collectively known as dCache.org. Beside a brief introduction into the dCache technology itself we will provide an insight into the project structure and the various organizations dCache contributes to and gets contributions by. The technical part will ocus on topics like the SRM 2.2 development, the integration of the improved file name space provider (Chimera), including the ACL plug-in, the pluggable authorization module (gPlazma), the various file location and scheduling mechanisms, the variety of dCache access protocols and many more. Last but not least we are eager to give an outlook on the upcoming short and mid term topics. These are the generic posix data access to dCache via the nfs4.1 protocol, the refurbished tertiary storage connector module, the dCache back-to-back transfer mechanisms and the enhanced meta data storage technology ,provided by chimera.
