Background (cont’d) • Fall ’03 meeting held in Vancouver at TRIUMF (http://www.triumf.ca/) • Web link: http://www.triumf.ca/hepix2003/ • All presentation slides and video of meeting available from “Programme” link • Refer to these for more detail and references/contact info • Meeting Summary available from “Summary” link
*NIX - Trends • Storage/File systems • Many investigating large scale storage solutions and global file system solutions (ala panasas, ibrix, etc…) • CERN setting up “Open Lab” joint venture with commercial entities • IDE raid widely used for bulk data • Tape Technology • STK and 9940b’s widely used • HPSS primary software used to manage
*NIX trends (cont’d) • Monitoring • Ganglia in use at many sites • Nagios is used at a couple of places
New this meeting • Vendor presence • Red Hat presentation on new software distributions • Microsoft presentation on sharing files between Windows and Linux • Panasas talk on Object Oriented storage • IBRIX demo suite
Presentations of interest • Fabric Management Tools at CERN • http://www.triumf.ca/hepix2003/pres/20-17/tkleinwort • Xml based • Node=manageable unit and needs to be autonomous (everything it needs stored locally) • Principles:configuration via one Node install and config reproducible • Success story: LSF upgrade from single tool, config info through one interface and stored centrally. 2.4 to 5.1 on >1000 nodes in 15 minutes, kernel upgrade, security updates • APT for RPM – Simplified Package Management • http://www.triumf.ca/hepix2003/pres/21-03/ftaurino • Alternate to yum. Good comparison of tools
