  1. Site report: CERN Helge.Meinhard@cern.ch HEPiX/HEPNT Autumn 2003 Vancouver

  2. Structure, management • CERN: Robert Aymar new DG as of January 1st • Major re-organisation expected • ‘Physics’ part of IT Division likely to remain unchanged • IT Management changes • F. Hemmer becomes leader of new middleware group for EGEE • C. Eck working fully for LCG • P. Anderssen replaces C. Eck as DI GL • D. Foster replaces P. Anderssen as CS group leader • Dissemination unit created in DI (F. Grey) 2

  3. Computer security • Windows RPC vulnerabilities  A. Pace, D. Heagerty • AFS password expiry • 12 months, users get notified by E-mail • Implementation being finalised • Hardware address registration enforced for portables • Procedures in place for CERN users and short-term visitors • Enforced already in IT buildings, rest of site before Christmas • Closure of off-site FTP on 2004/01/20 at the latest • Rules being established for system connected to CERN network • Defines acceptable network and security practices • Draft in preparation 3

  4. FIO – Fabric infrastructure and operations • ELFms management suite being deployed at large scale  T. Kleinwort • Components: • Quattor – configuration and installation • Lemon – monitoring and fault tolerance • Hardware management system • State management system • Quattor, Lemon making copious use of EDG WP4 tools • Outsourced system administration contract being replaced by in-house team of CERN hired system administrators (2nd level of 3-level model) 4

  5. FIO (2) • Procurements: carrying on with ‘white boxes’ for CPU servers and disk storage • Infrastructure for serial console for whole CC being deployed  H. Meinhard • Backup • Consolidating on TSM, new hardware bought • Legato phase-out: stop writing 12/03, last retrieval 03/04 • CDR: 250 TB for Compass, 115 TB for NA48 in 2003 • CC refurbishment ongoing • Civil engineering work for bunker for new 18 kV substation begun 5

  6. FIO (3) 6

  7. ADC – Architecture and Data Challenges • Castor (CERN advanced storage manager) • New stager being developed  J.-D. Durand • Storage Resource Manager ready for deployment • Framework discussed for support to external institutes • Preparing for next Alice computing challenge, aim is 300 MB/s sustained from online to tape 7

  8. ADC (2) • CERN OpenLab • OpenCluster: grid enabled compute and storage farm • ~40 HP dual processor Intel Itanium machines • RedHat AW 2.1, OpenAFS 1.2.7, gcc 2.96, 3.2, 3.3, icc 7, 8beta, LSF 5.1 • Enterasys 10 Gbit switches • IBM StorageTank high-capacity storage system – tests, benchmarking • Applications compiled and verified: Root, CLHEP, Gean4, Aliroot (including large fractions of CERNLIB), online software • Workshops: • 03/03 Storage and Data Management • 07/03 Fabric Management • 11/03 Total Cost of Ownership 8

  9. ADC (3) • RedHat certification…  J. Iven, A. Silverman • Work horse is RH 7.3 • RH 6.1 phased out • Except for a few 10 machines needing it for Objy/DB • Aim was to conclude certification of new Linux in time such that systems could be upgraded during CERN machine shutdown in winter • Started certification based on RH 10 beta (severn) • RH announced more support policy changes • CERN put certification on hold… awaiting this meeting 9

  10. DB – Data Bases • POOL – persistency framework • 1.3.2 released • Successfully integrated into Atlas and CMS software frameworks • CMS reporting 700 k simulated events in POOL • RLS service being deployed on testbeds, distribution kits available • Ever more physics applications require DB services • Oracle 10g out, many new features 10

  11. GD – Grid Deployment • LCG-1 being deployed  I. Neilson, D. Smith 11

  12. IS – Internet Services • Windows XP Professional deployed • New PCs delivered with XP (and/or Linux) • No upgrade campaign for Windows 2000 • Support for NT and 95 stopped earlier this year • Mail migration from IMAP servers on Solaris to Exchange (with improved Anti-Spam tools) well advanced  A. Pace • Evaluating M$ SUS (Software Update Service) for deploying security updates 12

  13. IS (2) • Pilot service for Windows Terminal Server  A. Pace • Web-based file systems, gateway to DFS  A. Pace • CPU cycles from Windows screen saver for simulation • Project advancing 13

  14. PS – Product Support • CVS service in full swing  S. Lopienski • Solaris services being consolidated  S. Lopienski • Some ELFms components ported to Solaris • Phasing out Alpha servers for EDMS and engineering applications • Replacements: Solaris, Windows • Euclid client migration to Windows completed • Migration to new print server system completed • Special clusters for GdfidL (7 dual Xeon machines with 4 GB memory each) and StarCD (Solaris) • Desktop support contract being re-tendered 14

  15. CS – Communication Systems • Current GSM contract expires by 12/03, new contractor as of 01/04 • Transition being prepared • STM-64 line CERN – Chicago operational • Replacing STM-4 • ACB (Automatic Call Back) for connections from home to CERN under discussion 15

  16. AOB • LEP data archiving • Requested by CERN Management • HW, SW, data (25 TB/exp), expertise to be kept alive for ≤ 20 y • Exps with different schedules for wind-down of their activities • Working group set up, more understanding expected until 12/03 • Mac support… • A little, focused on MacOS X • Encouraging self-help of user community • Aim is interoperable browsers, mail clients, web authoring etc.; central application and home directory services on Windows DFS infrastructure • Implementation being prepared 16
