Now 23 approved VOs
5Glenn Patrick LHCb Software Week – 28 April 2006
UK Tier 1 CPU
Current capacity 830 KSI2K.Some units now 4 years old.
Extra 266 KSI2K delivered 10 March and should be available at start of May after 4 week load test.
Twin dual-core Opteron 270s:• 1GB RAM/core• 250 GB HDD
Total CPU Capacity = 1,096 KSI2K
6Glenn Patrick LHCb Software Week – 28 April 2006
UK Tier 1 Disk
Current capacity 177TB.
Extra 168TB and 21 servers deliveredon 10 March.
Some teething problems. Fix has been generated and tested.
Hopefully, resume installation this week with target for end May.
Total Disk Storage ~308TB(after retirements).

New SL8500 tape robot
New STK SL8500 tape robot.
•Replaces STK Powderhorn 99310 robot (single arm, 9940 drives)
•Funded by CCLRC. Entered service 28th March 2006.
•6,000 slots. Upgrade to 10,000 slots later in the year giving a capacity of 5 PBytes.
•8 mini robots mounting tapes – faster, more resilient.
•T10000 tape drives (Castor and not ADS at moment).
318TB(Feb) 336TB 446TB (extra T10K media)

CASTOR2 Deployment
Mar-Apr Testing: functionality, interoperability and database stressing
May-Sep Spec and deploy hardware for production database
May Internal throughput testing with Tier 1 disk servers
Jun CERN Service Challenge throughput testing
Jul-Sep Create full production infrastructure;full deployment on Tier1
Sep-Nov Spec and deploy second phase production hardware to provide full required capacity
Apr 07 Startup of LHC using CASTOR at RAL
dCache available
until early
2007
