VPAC Seminar: “Data Management and Storage Technology in EGEE”,

5^th February 2007

Introduction:

Distributed management of data is one of the most important problems facing grids. Within the Enabling Grids for Enabling eScience (EGEE) project, currently the world's largest production grid, asophisticated hierarchy of data management and storage tools have been developed to help Virtual Organisations (VOs) with this task. n this paper we review the technologies employed for storage and data management in EGEE, and the associated Worldwide LHC Computing Grid (WLCG). We describe from low level networking and site storage technologies, through data transfer and cataloguing middleware components. A particular emphasis is placed on deployment of these services in a large scale production environment. We also examine the interface between generic and VO specific data management, taking the example of the ATLAS high energy physics experiment at CERN

Bio:

Graeme Stewart graduated with a PhD in Plasma Physics from the University of Glasgow in 1992. He then spent 4 years in Mexico studying the solar corona and developing magnetohydrodynamic simulations, something that seemed to require drinking lots of beer called Corona. After returning to Scotland in 1997 he briefly worked as a C++ programer in telecoms before returning to the University of Glasgow to work in the Astronomy Group. In 2005 he mutated from an astronomer to a particle physicist, starting work on data management problems within the UK's particle physics grid, GridPP. Currently he is the Technical Co-ordinator for the ScotGrid distributed Tier 2 site, which covers Glasgow, Edinburgh and Durham, as part of the European Enabling Grids for eScience project. He regularly threatens grid middleware with violent retribution.
