The Large Hadron Collider (LHC) at CERN, the European Organisation for Nuclear Research, will produce unprecedented volumes of data when it starts operation in 2007. To provide for its computational needs, the LHC Computing Grid (LCG) is being deployed as a worldwide computational grid service, providing the middleware upon which the physics analysis for the LHC will be carried out.

Data management middleware will be a key component of the LCG, enabling users to analyse their data without reference to the complex details of the computing environment.

In this paper we review the performance tests of the LCG File Catalog (LFC) and make comparisons with other data management catalogs. We also survey the deployment status of the LFC within the LCG.
