Welcome to the DataManagement TWiki

Data Management Architecture Team


  • 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

Release Planning

Documents and Presentations

Project plans

The architecture team has given a first status report to the Physics Services Meeting on 19/06/08 and proposed to start the following development projects:

Integrated Monitoring

Stager Improvements and XROOTD (support for analysis use cases)

Database Deployment and Schema Consolidation

Tape Efficiency


Prototype Studies

As part of the architecture discussions the following proof-of-concept prototypes were developed:

Physics Analysis Disk Pool - prototype test plan

Xroot based Disk Pool File System


2nd generation Xrootd/Castor2 Interface


Test System

xrootd based Disk Server Testsystem
