CERN Site Report Helge Meinhard / CERN-IT HEPiX Spring 2010 “LIP Lisbon” 19 April 2010

2 LHC Status (1) Date Event 10-Sep-2008 First beam in LHC 19-Sep-2008
Leak when magnets ramped to full field for 7 TeV/beam 20-Nov-2009 First circulating beams since Sep-2008 23-Nov-2009 Circulating beams both ways, first collisions at 2 * 450 GeV 30-Nov-2009 World record: 2 * 1.18 TeV, collisions soon after 16-Dec-2009 End of run, more than one million collisions recorded by each of the four experiments 28-Feb-2010 Beams back 19-Mar-2010 Another world record: 2 * 3.5 TeV 30-Mar-2010 First collisions at 2 * 3.5 TeV, special day for the press CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

3 LHC Status (2) Future plans
Run for 18…24 months at 2 * 3.5 TeV to collect one inverse femtobarn 2012: Shutdown to prepare machine for 2 * 7 TeV CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

7 WLCG Coping well with initial data taking
ATLAS exporting data from T0 at 1 GB/s Others at design specs as well Tests have shown up to 3 GB/s CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

8 ITIL ‘Best practices’ approach
Most IT staff followed course and passed exam Service catalog (with dependencies) done Incident management workflow done Change fulfilment workflow done Implementation ongoing Resulting in a common service desk for IT and GS CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

9 Computing Facilities (1)
Addressing shortfalls of capacity in CC Critical power: running 340 kW on a supply safely designed for 250 kW Non-critical (“physics”) power: need to extend 2.5 MW for upgrades required for LHC Remote hosting: short-term Hosting centre selected at ~15 km from CERN 15 racks, 40 m2, 100 kW Intense preparations First systems to be moved in May/June Remote hosting: long-term Some expressions of interest from CERN member states Awaiting concrete offers CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

10 Computing Facilities (2)
Addressing shortfalls of capacity in CC (cont’d) Containers Price enquiries/tenders ongoing Location on CERN site identified Extension of building 513: Refurbishment of “barn” area Planning started Shutdown procedures for non-critical services established Operators will shut down equipment if power lost for more than 3 minutes CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

11 Computing Facilities (3)
Procurements: Volume Recent deliveries include 2’188 CPU servers All as four dual-CPU (Nehalem) systems in a 2U enclosure 613 Disk servers 4U, 24 * 2 TB, single Nehalem, RAID card 1 PB external (iSCSI) storage with front-end servers 224 midrange servers 60 tape servers 38 small disk servers 109 disk arrays Market survey for servers, and one for storage, done Tenders for 2011 capacity have started CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

14 CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

15 Computing Facilities (4)
Procurements: Fun points MCE errors Memory messup (non-uniform across delivery) RAID controller fun Soldering interventions on mainboards Systematic disk drive drops Upgrades of BIOS and BMC Disk drive firmware upgrades … CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

16 Communication Systems
Re-tendering blanket purchase contracts for routers and switches SIM card replacement: More than 3’500 SIM cards replaced during one week CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

17 Databases Services Oracle and LHC running
Production databases on Oracle 10 Support for 10 ends by mid 2011, i.e. before the end of the run Extending support for 10 will cost money (also for T1 centres requiring it) Upgrade to 11 in time may be difficult CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

18 Data and Storage Services
Lustre evaluation completed See Tim Bell’s talk All disk servers upgraded to SLC5 Backup will continue with TSM Castor stagers upgraded to 2.1.9 CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

19 Operating Systems and Information Services (1)
Windows support Windows 7 (both for 32-bit and 64-bit) supported for selected HW configs since Jan-2010, general support since 31-Mar-2010 Phase out Vista within the next months (no new installs) Exception for engineering PCs requiring Vista 64bit Phase out XP to be clarified Mail services Due to incompatibility with pine and alpine clients, Exchange 2007 will be skipped Sharepoint Sites being migrated to MOSS 2007 SP2 CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

20 Operating Systems and Information Services (2)
Anti-virus Migration from Symantec anti-virus to Microsoft Forefront Print infrastructure New print servers about to be released in production Some client-side changes, including on Linux, being deployed Linux support Support for ia64 stopped Existing machines will still get security updates CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

21 Platform and Engineering Services (1)
Lxplus Alias not yet moved from SLC4 to SLC5 Requires more interaction with users Numerous packages added to minimalistic setup that SLC5-based release started with Lxbatch / lxparc Some users with need for parallel applications Fitting 40 dual-CPU nodes with 10GE interconnect Linux updates Changes to monthly update procedure: Preparing versioned package list rather than pushing update onto all machines actively CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

22 Platform and Engineering Services (2)
Virtualization See Ulrich Schwickerath’s talk Performance issues under Hyper-V with external storage and Linux guests Twiki See Pete Jones’ talk Storage backend moved from AFS to NFS SVN Ramping up, projects and activity on the rise, replacing in most cases cvs repositories Moving servers from cvs to svn Svn server is 1.5, clients on RHEL/SL/SLC are 1.4 Interoperability issues CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

23 User and Document Support
Indico New version released in production Development contributions by FNAL, DESY, GSI Perhaps more to come CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

24 Security ssh attacks continuing
Web servers disclosing confidential information Campaign to promote secure coding Scan of AFS file space to detect directories with files containing confidential information not protected properly Phishing attacks – CERN users getting used Security base lines for servers, Web space, … Planning for a security awareness day Firewall openings being reviewed Looking into source code analysis tools CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch

25 Miscellaneous Solaris and Sparc phased out Replaced mostly by Linux
Few services with Windows CERN Site Report for HEPiX Spring 2010 – Helge Meinhard at cern.ch
