  1. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Site report HIP / CSCHIP : Helsinki Institute of Physics CSC: Scientific Computing Ltd.(Technology Partner) Storage Elements (dCache) for ALICE and CMS

  2. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC What's happening here ? ALICE : part of the NDGF T1-centre CMS : T2-centre Storage-Elements (dCache) Computing-Elements (arc, gLite)‏

  3. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Hardware installation Disk : Server (HP-Blades):¤ CMS : 5¤ ALICE : 2¤ Cold spare : 1 ¤ CMS : ~100 TB¤ ALICE : ~70 TB Tape : ¤ ALICE : ~64 TB 1styr

  4. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Server-Installation: HP-Blades with own chassis¤ 64Bit, 2x4 cores, 2.33 GHz ¤ 12 GB RAM¤ mirrored System Disk¤ 6x 1GB Ethernet¤ 2x FC 4Gb (QLogic) ¤ Scientifc Linux 5.x

  5. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Server-Installation: ALICE : CMS : • 2 Pool-Nodes • 1 Admin-Node • 1 SRM-Node+ xrootd-Door • Tape-Server (CSC-internal, SAM-FS)‏ • 3 Pool-Nodes (+gridftpDoor)‏

  6. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Disk-Installation: Hitachi Mid-Range Raid-System Mostly SATA, some FCconnected via multipathed SAN

  7. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Tape-Installation: Use of existing Tape-server at CSC. Type : SAMFS Connectors to dCache written by CSC(but still to be implemented)‏

  8. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Network: dCache-Servers: private and public interfaces (1GB/s)public: 1GB FUNET uplink(Will be connected to OPN “after summer”)private: shared with CE “sepeli”, pools are bonded to 4GB/s each, admin/srm : 1GB/s

  9. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC dCache Setup: admin-Node : pnfs, psql, adminDoor et. al.srm-Node : srm, psql, xrootdpool-Nodes : pool, gridftp, 24 TB disk

  10. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Monitoring: Accessible with Grid-certificate via:https://duchess.csc.fi ¤ dCache-pages ¤ srmwatch ¤ ntop

  11. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Monitoring - dCachepages www.dcache.org

  12. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Monitoring - srmwatch search web for : srmwatch dcache, not yet fully functional.

  13. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Monitoring - ntop www.ntop.org dCache traffic, here gridftp WAN-ifce pool-node, still some work to be done here.

  14. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Future plans ¤ attach tape to ALICE pools ¤ work in progress : ¤ srmwatch ¤ ntop/dCache ¤ nagios monitoring ¤ set up workflows for dCache (remove pools, consistency checks, functionality checks)

  15. Christof Hanke, HEPIX Spring Meeting 2008, CERN Site report HIP / CSC Thank you for your attention.Comments ? Questions ?
