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

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) 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 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 Christof Hanke, HEPIX Spring Meeting 2008, CERN

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

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

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

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

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