Rosenthal Pavilion (10th floor) 2012-05-22T13:30:00 2012-05-22T18:15:00 04:45 This paper reports the design and implementation of a secure, wide area network, distributed filesystem by the ExTENCI project, based on the Lustre filesystem. The system is used for remote access to analysis data from the CMS experiment at the Large Hadron Collider, and from the Lattice Quantum ChromoDynamics (LQCD) project. Security is provided by Kerberos authentication and authorization with additional fine grained control based on Lustre ACLs (Access Control List) and quotas. We investigate the impact of using various Kerberos security flavors on the I/O rates of CMS applications on client nodes reading and writing data to the Lustre filesystem, and on LQCD benchmarks. The clients can be real or virtual nodes. We are investigating additional options for user authentication based on user certificates. We compare the Lustre performance to those obtained with other distributed storage technologies. slides doc http://indico.cern.ch/images/word.png word file ppt http://indico.cern.ch/images/powerpoint.png powerpoint file pdf http://indico.cern.ch/images/pdf_small.png pdf file odt http://indico.cern.ch/images/writer.png writer file odp http://indico.cern.ch/images/impress.png presentation file ods http://indico.cern.ch/images/calc.png spreadsheet file other http://indico.cern.ch/images/file_small.png unknown type file link http://indico.cern.ch/images/link.png link 2013-06-18 2013-06-19
