  1. LCG Service Challenge: Planning and Milestones Tiziana.Ferrari@cnaf.infn.it INFN CNAF Review Mar 1, 2006

  2. Outline • Service Challenge 4 schedule • SC3 and pre-SC4 results • SC4: • CNAF hw resources and milestones • Service planning • Personnel

  3. SC Milestones 2006 January SC3 disk repeat – Nominal rate (200 MB/s) capped at 150MB/s/ February CHEP Workshop; T1-T1 Use Cases, SC3 disk - tape repeat (50MB/s, 5 drives) March Detailed plan for SC4 service agreed (M/W + DM service enhancements). gLite 3.0 release beta testing April SC4 disk – disk (200 MB/s) and disk – tape (75MB/s) throughput tests. gLite 3.0 release available for distribution MayInstallation, configuration and testing of gLite 3.0 release at sites June Start of SC4 production tests by experiments of ‘T1 Use Cases’ T2 Workshop: identification of key Use Cases and Milestones for T2s July Tape throughput tests at full nominal rates! August T2 Milestones – debugging of tape results if needed September LHCC review – rerun of tape tests if required October WLCG Service Officially opened. Capacity continues to build up November 1st WLCG ‘conference’. All sites have network / tape h/w in production(?) DecemberFinal service / middleware review leading to early 2007 upgrades for LHC data taking??

  6. LHCb: FTS channel mesh testingJan-Feb 2006 CNAF

  7. SC3: CMS, Phase 1 report (Sep-Nov 05) • Objective: 10 or 50 TB per Tier-1 and ~5 TB per Tier-2 (source: L.Tuura)

  8. SC3: LHCb report Phase 1 (Oct-Nov 05, Data moving) • Less than 1TB stripped DSTs replicated. At INFN most of this data already existed with only a few files missing from the dataset therefore it was only necessary to replicate a small fraction of the files from CERN (source: A. C. Smith) • Configuration of an entire CNAF-to-Tier1 channel matrix (for replication of stripped data)

  9. SC3: ATLAS • Production phase started on Nov 2 • 5932 files copied and registered at CNAF: • 89 “Failed replication” events • 14 “No replicas found”

  10. SC4 Hardware Resources at CNAF • 2500 CPU slots (out of 1000 physical CPUs) • LHC: up to 2500 CPU slots(Worker Nodes are shared) • SLC 3.0.4 and LCG 2.6.0 • Disk: 400 TB (including the Castor buffer space) • LHC: 100 TB (including the Castor buffer space) • Tape: 260 TB (7 9940B + 6 LTO2 drives) • LHC: 160 TB • Network available bandwidth (CERN – CNAF): • 10 Gb/s • CNAF – T2 connectivity already tested (Bari, Catania, Legnaro, Milan, Pisa, Torino) • CNAF – Karlsruhe connectivity (1 Gb/s, MPLS): under implementation

  11. LCG CNAF Milestones (1st Q 2006) 16.01.06 150 MB/s (SC3 disk-disk, throughput test rerun) ☺ Feb 2006 upgrade to CASTOR v2 (installation started on Dec 1 2005)  ongoing Feb 2006 purchase of additional 120 TB on tape  ongoing Feb 2006  all required sw baseline services deployed (SRM, LFC, FTS, CE, RB, BDII, RGMA) ☺ Mar 2006 setup of CNAF – Karlsruhe backup connection Mar 2006 evaluation of dCache and StoRM (for disk-only SRM) Tier-2’s: Definition of INFN Tier-2 service plan is ongoing

  12. Candidate Tier-2 sites in SC3 (Oct 05) • Torino (ALICE): • FTS, LFC, dCache (LCG 2.6.0) • Storage Space: 2 TBy • Milano (ATLAS): • FTS, LFC, DPM 1.3.7 • Storage space: 5.29 TBy • Pisa (ATLAS/CMS): • FTS, PhEDEx, POOL file cat, PubDB, LFC, DPM 1.3.5 • Storage space: 5 TBy available, 5 TBy expected • Legnaro (CMS): • FTS, PhEDEx, Pool file cat., PubDB, DPM 1.3.7 (1 pool, 80 Gby) • Storage space: 4 TBy • Bari (ALICE/CMS): • FTS, PhEDEx, POOL file cat., PubDB, LFC, dCache, DPM • Storage space: 1.4 TBy available, 4 TBy expected • Catania (ALICE): • DPM and Classic SE (Storage space: 1.8 Tby) • LHCb • CNAF

  13. SC4 Service Planning – CNAF (1/2)

  14. SC4 Service Planning – CNAF (2/2)

  15. Personnel • Storage group: Castor, Castor2, dCache, FTS • Network group: LHC OPN CNAF – CERN link configuration • Farming group: from October 2005 • Grid operations group: • installation, testing, monitoring of SC services • SC coordination at INFN: • Tiziana Ferrari (CNAF) • Michele Michelotto (INFN Padova, deputy) • INFN SC mailing list • Tier-2 relying on local man-power, working in close collaboration with CNAF
