  1. ITD/CLRC Site Report Andrew Sansum HEPSYSMAN@RAL 21 March 2000 A.Sansum@rl.ac.uk

  2. Linux • 20 Dual Processors in production • 40 Dual PIII 600 MHz arrived and being installed • Farm Upgrade to Redhat 6.1 shortly • Move from NQS to PBS soon • Working on smarter installs and upgrades - kickstart/autorpm • Provided demand exists order additional 30-40 PIII 800+MHz cpus in the summer

  3. Linux Growth at Current Spend

  4. NT FARM • LHCB Production • 200K+ events with early versions of SICb • Full production about to start • Front End • NT Terminal Server • Citrix Metaframe being installed at the moment - providing X11 access from Unix • ImageCast being used for system cloning

  5. HP Farm • Beginning to Plan Rundown of the Service • Oldest (HP 735 nodes) already taken out of service • Termination date will probably be agreed with CNAP on Thursday

  6. Network • Wide-area network transfers becoming more common at RAL as a means of shipping HEP data around the UK/world. • Thus need to put in place more control / monitoring software (presently mrtg and ntop). • Growing interest in QoS and managed bandwidth - also smarter (level 3) switches. • Gigabit Ethernet (within HEP network) will probably become necessary this year • GRID Stuff!

  7. Security • Network security situation continues to deteriorate - many probes daily • Security related workload will continue to increase over the year. • Site is gradually tightening its firewall - with some success (No incidents since November) • Beginning to automate scan detection and counter-measures (router blocks) • Beginning to look at eliminating clear-text passwords within the site.

  8. Conclusion • Linux service continues to grow • NT Farm/Solaris stable • HP Farm beginning to ramp down • Growing interest in technology to manage the network • Security - some gains made but continues to be a (growing) concern
