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 (75 MB/s) throughput tests.
gLite 3.0 release available for distribution
May Installation, 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(?)
December Final service / middleware review leading to early 2007
upgrades for LHC data taking??

4. Disk – disk throughput test rerun (Jan 06)

6. LHCb: FTS channel mesh testing Jan-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. Production phase started on Nov 2
SC3: ATLAS
Production phase started on Nov 2
5932 files copied and registered at CNAF:
89 “Failed replication” events
14 “No replicas found”
