Hi Pete, Andy, I've been persused to give this talk at hepix next week. You can see the first draft at: http://hepwww.rl.ac.uk/ppdstaff/brew/public/BaBarGrid/Talks/RAL-Xrootd.p pt Since as far as I'm aware xrootd hasn't been presented at hepix before there's a section at the start with a short discription (Andy might recognise some of the phrasing) followed by a description of how it's deployed here and our experience. Is there anything you'd like me to add, remove or clarify? I was thinking possibly of a slide at the end of the description with some performance/scaleability numbers. Any other comments are welcome. Thanks, Chris. -- Chris Brew ([log in to unmask]) +44 1235 446326 Particle Physics Department Rutherford Appleton Laboratory Chilton, Didcot. Oxfordshire. OX11 0QX. United Kingdom.
