After the last appointment in December 2015 at CERN, we are proud to invite you to join the DPM workshop 2016 at LPNHE (Paris), organized with the kind support of the French DPM community.

DPM is one of the most important storage managers of the Grid environment. It is installed in roughly 160 sites, hosting more than 70PB of massively accessed data. One of the strongest aspects of DPM is the cooperation with the numerous system administrators that have deployed it, and the goal of the DPM workshop is to discuss the aspects that are related to it.

This last year has seen an intense development phase, with the aim of concluding the work on the DPM core components whose discussion started at the previous workshop. The evolution of DPM continues with items like making SRM optional together with the legacy libraries, directory-based space accounting and quotas, emphasizing the consolidation of the technologies inside DPM. The emphasis on the setup continues.

Keeping the continuity from the discussions of last year, this appontment in LPNHE is dedicated to show and discuss items like:

  • current status of the implementation of the features
  • smooth transition plan to using DOME: the new DPM core
  • preparing for VOs that will abandon SRM, providing old and new services and features
  • current status of the deployment in sites
  • points of view of the system administrators, that made DPM a successful system
  • current status of the codebase
  • new metapackage structure
  • availability of the packages in the mainstream repositories
  • federating DPMs using the Xrootd and HTTP protocols

      DPM 1.9 - From the standard flavour to the DOME setup flavour - Features, system architecture and configuration 20m

      DPM 1.9 can be configured in two flavours: the "legacy" (the default, using the legacy components) and the "advanced" one, which enables the advanced features of the Disk Operations Management Engine (DOME). In this contribution we have a look at where DOME is placed in the architecture, how to configure it, how to enable it, how to pass from the DPM legacy flavour to the advanced one and back.
