1. Site Report: CERN Helge Meinhard / CERN-IT HEPiX, Jefferson Lab 09 October 2006

2. Communication Systems  Checking VoIP and possible gateways  New audio conference system with Web- based booking  New LCG backbone in CERN CC fully operational  Existing LCG services being migrated

3. Database and Engineering Support  Oracle  Licence agreement for LHC covering 10 of the 11 Tier 1 sites as well  Very serious bug in 10.2.0.2: Wrong cursor sharing  Took several weeks to provide a fix  Evaluating NAS storage for databases  Twiki: migrated to version 4  See talk by Hege Hansbakk later  CVS services going well  CMS moved their repositories

4. Fabric Infrastructure and Operation (1)  Linux  SLC4 for LHC startup (SLC5 too late, probably not before 2Q or 3Q 2007)  Support for SLC3 to stop October 2007  SLC4 capacity set up in lxplus and lxbatch  Operations contract re-tendered  SURE (alarm GUI for CC operators) replaced by LAS  Lots of service interruptions  Power cuts  Partly site-wide  Failures of air conditioning  Emergency shutdown of non-critical machines

5. Fabric Infrastructure and Operations (2)  Machines coming in  95 serial console concentrators  30 dual-core AMD servers (yeah…)  100 CPU servers (dual-core Woodcrest)  200 midrange servers  60 disk arrays  50 small disk servers  Partly need 100 cm deep racks  In the pipeline: 650 CPU servers, 180 big disk servers  Study cases: fat disk servers (SW RAID?), virtualisation  Technical student working on IPMI functionality and deployment

6. Fabric Infrastructure and Operations (3)  New tapes / robots from IBM and Sun tested extensively  Tender based on service for Petabytes, including all media costs  Final decision awaiting approval by CERN Finance Committee  More detailed planning for LHC accelerator start-up  “January 2007” delivery is probably the only one for 2007  Service Level Status Overview  See talk by Sebastian Lopienski later

7. Fabric Infrastructure and Operations (4)  Castor 2  Most migrations done  Positive conclusions from Castor Readiness review  Backup  TSM based, 35% annual growth rate  Working on replacing AIX servers by Linux  Console manager software  Lots of improvements, common code repository SLAC/CERN  S.M.A.R.T. sensors now used to raise alarms  See talk by Tony Cass later  Odds and ends  Faulty disk sleds replaced by cages on 60 older disk servers  Firmware upgraded on 1300 SATA disks

8. Grid deployment  Upgrade to gLite 3 went very well  Service challenge 4 ongoing  Not yet production quality everywhere  Workshop for Tier 2s very successful

9. Internet Services (1)  Insecure mail protocols switched off  POP / IMAP without SSL  Anonymous SMTP  Anonymous LDAP  Evaluating providers of real-time spam blocking lists  Whitelisted collaborating labs

10. Internet Services (2)  Printing: Printers being moved from old Linux boxes to Windows servers  No server-side processing any more  Windows on demand: virtual servers in production  See presentation at HEPiX Rome  CERN CA production-ready, awaiting accreditation  Users on XP without admin privileges by default

11. Internet services (3)  Computer Management Framework (CMF) put into production  Presented at HEPiX in Rome  Flexible choice of setup while maintaining strong management (patches can be forced)  Few initial hiccups, but now going well  Odds and ends  24 power supply modules broke – servers had been switched off, but connected to AC power. PSU fans not spinning, overheat

12. Physics Services Support  All physics database services migrated to Oracle RAC  Two new RAC installations (30 servers, 30 disk arrays each) being set up

13. Computer Security  Mac OS X: Exploits have been seen  CERN firewall: All TCP and UDP ports closed by default  Some Linux boxes root-compromised due to weak passwords  Serious security hole in VNC product has accelerated VNC port blockage  Reviewing the need for outside visible ssh servers (reduced by 80%)  Compromised Web server (vulnerable PHP scripts)  Insecure security products  Vulnerability in Symantec AntiVirus 10.0.2000

14. Miscellaneous  Computer user registration: CCDB replaced by CRA  Accounts blocked automatically  CERN Openlab phase 2: HP, Intel, Oracle as partners, some more contributors  CERN active in Open Access initiative
