  3. IT Support Requirements for CERN Controls • The Work – what is done • Intermediate Results • Observations • The Work – what remains E. Hatziangeli (SL/CO)

  4. The Work – what is done • Work started in October 2001 • People involved: • E. Hatziangeli (SL) • A. Silverman (IT) • Interviewed 25 people in 7 two hours sessions: • LHC/IAS • The LHC Cryo project • PS/CO • ST/MO (MA), ST/AA (MA), ST/EL, ST/CV • IT/CO • EDMS E. Hatziangeli (SL/CO)

  5. The Work – what is done • Domains of support: • Network • Fileservers & File Systems (AFS, NFS) • OS (Linux, W2K) • Oracle • WEB infrastructure • Tools (PVSS,PLC eng. tools, LabView, 3rd party, SCM, dev.,WEB publishing) E. Hatziangeli (SL/CO)

  6. IT Support Requirements for CERN Controls • The Work – what is done • Intermediate Results • Observations • The Work – what remains E. Hatziangeli (SL/CO)

  7. Intermediate Results • Network support • Need for controlsprivate subnet • High availability 24hx7d • Short “response + back to service” time ~ 1 - 4h • General satisfaction with current level of support • Need to monitor/diagnose network problems from CRs • Need priority access to IT resources when problems • Secure access to controls from outside CERN E. Hatziangeli (SL/CO)

  8. Intermediate Results • Fileservers, File Systems • Access to files from all systems (AFS, NFS, DFS) • Available IT supported technology • OS • Exempt from default upgrades/patch distribution • Oracle • Considered as the best IT supported service • High availability • WEB • Secure web servers (no visibility offsite) • Tools (PVSS,PLC eng. tools, LabView, 3rd party, SCM, dev.,WEB publishing) • Should be supported and configured by IT • Centralized support for licenses E. Hatziangeli (SL/CO)

  9. IT Support Requirements for CERN Controls • The Work – what is done • Intermediate Results • Observations • The Work – what remains E. Hatziangeli (SL/CO)

  10. Observations • Areas of Concern • Controls groups need to be convinced that IT could provide the level of support necessary for operations • High priority problem resolution 24hx7d during run time • TCR 24hx7x365 for many central IT services • Remarks • Several common requirements • centralized support makes good sense • Solution differ for similar problems • rationalization of solutions and support is necessary • Local duplication of services to ensure high availability • centralized support makes better sense E. Hatziangeli (SL/CO)

  11. IT Support Requirements for CERN Controls • The Work – what is done • Intermediate Results • Observations • The Work – what remains E. Hatziangeli (SL/CO)

  12. The Work - what remains • Interviews completed by end December 2001 • SL/CO, SL/BI, SL/BT, SL/OP, SL/EA (CESAR) • URDs • Confirmed and completed by end of February 2002 • 2nd CB progress report • IT • Document response of March 2002 • Final results to CB by April 2002 – final report • Support proposal is published by end April 2002 E. Hatziangeli (SL/CO)
