Fundamental physics research has always relied upon the latest in state-of-the-art computer hardware, even to the point of demanding purpose-built supercomputing resources. Now, modern lattice quantum chromodynamics research demands not only the best hardware available, but the best Grid software as well. The Terabytes of raw physical data created in this field and the complex metadata used to describe it together form a significant challenge to current Grid design and implementation.

UKQCD, part of the wider GridPP collaboration, already has some five Terabytes of data on the J90 mass store at EPCC and as the forthcoming QCDOC hardware comes on line, the demand for a secure, reliable and expandable distributed-storage resource can only increase. The aim of the QCDgrid project is to satisfy this demand, providing a multi-Terabyte storage system over four UK sites (at Edinburgh, Glasgow, Liverpool & Swansea) based on commodity hardware and open-source software. The hardware consists of a set of RedHat Linux PCs using large RAID arrays of harddiscs. The software is based on the European DataGrid (which itself is based upon Globus 2.0), atop which lies an XML Database Server (XDS) for storing and querying the metadata, along with a set of graphical and command-line tools by which researchers may store, query and retrieve the data held on the grid.
