Helge.Meinhard (at) cern.ch 2HEPiX Vancouver: CERN site report

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)


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


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)


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


FIO (3)


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


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


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


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


GD – Grid Deployment

LCG-1 being deployed I. Neilson, D. Smith


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


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


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


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


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
