Data Management

From GridPPwiki

Welcome to the GridPP DataManagement wiki

This section of the wiki is (was?) maintained by Graeme Stewart, specifically to help support UK Tier 2 sites as part of the GridPP (http://www.gridpp.ac.uk/) project. It may also contain things of interest to end users of the LHC Computing Grid (http://lcg.web.cern.ch/LCG/), and anyone else interested in data management issues in grids.

Also maintained by the GridPP Storage and Data Management Group.

Data Management for Sites

For GridPP Tier 2 sites the key data management service which needs to be installed is a local install of the LCG File Catalog.
Tier 2 DM Requirements gives the client components you need at your site.
File Catalog Maintenance gives advice on how to manage files stored at your site which are found in experiment file catalogs.
