For 2006 the following site shares were used:

ASGC to provide 10% of pp resources CNAF to provide 13% of pp resources FNAL to provide 28% of pp resources FZK to provide 8% of pp resources IN2P3 to provide 10% of pp resources PIC to provide 5% of pp resources RAL to provide 3% of pp resources

CMS Distribution of activities over 2006

Month CMS Requirements
April 2006 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk at each Tier 1. Data to be distributed from CERN at 10MB/sec to ASGC, 25 MB/sec to CNAF, 50 MB/sec to FNAL, 15 MB/sec to FZK, 15 MB/sec to IN2P3, 30 MB/sec to PIC and 10 MB/sec to RAL (based on tape pledges in Mou). May be satisfied by SC4 throughput tests
May 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk at each Tier 1
June 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk at each Tier 1. SC3 functionality rerun using gLite infrastructure rising to 25000 jobs/day aggregated over all sites by end of June
July 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk at each Tier 1. Monte Carlo from Tier 2 incoming to each Tier 1 aggregating to 1TB/day to CERN. Total of 25M events in month. Test Tier 2 to Tier 1 transfers at 10 MB/sec per Tier 2. Last 2 weeks of July transfer 150 MB/sec simulated raw data to tape at Tier 1s split 10 MB/s to ASGC, 25 MB/s to CNAF, 50 MB/s to FNAL, 20 MB/s to Gridka, 25 MB/s to IN2P3, 20 MB/s to PIC and 10 MB/s to RAL. Data to be kept for 24 hours but possibly a few months (to be decided later).
August 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk at each Tier 1. Monte Carlo from Tier 2 incoming to each Tier 1 aggregating to 1TB/day to CERN. Total of 25M events in month. Test Tier 2 to Tier 1 transfers at 10 MB/sec per Tier 2. During first two weeks of August perform Tier 0 to Tier 1 disk to disk transfers at an aggregate rate out of CERN of 500 MB/sec. After the 500 MB/s disk-disk tests return to complete the transfer at 150 MB/sec simulated raw data to tape at Tier 1s split 10 MB/s to ASGC, 25 MB/s to CNAF, 50 MB/s to FNAL, 20 MB/s to Gridka, 25 MB/s to IN2P3, 20 MB/s to PIC and 10 MB/s to RAL. Switch these sites to tape progressively on individual negotiation. Data to be kept for 24 hours.
September 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk at each Tier 1. Continue the 150 MB/s raw data export till mid-September. From mid-September ramp up to the official 1 October start of CSA06 at 50000 jobs/day. 1500 cpu at Cern, 600 cpu at FNAL, 350 cpu at CNAF and 150 cpu at other T1. Most of the data to stay on disk at T1 (typically needing an aggregate for CSA06 of 70TB disk) but smaller sites can fault to tape.
October 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk at each Tier 1. CSA06 at 50000 jobs/day. 1500 cpu at Cern, 600 cpu at FNAL, 350 cpu at CNAF and 150 cpu at other T1. Most of the data to stay on disk at T1 (needing an aggregate for CSA06 of disk at CNAF of 160TB, at FNAL of 280TB and at each other Tier 1 of 70TB) but smaller sites can fault to tape.
November 20 MB/sec aggregate Phedex (FTS) traffic to/from temporary disk at each Tier 1. Demonstrate 300 MB/sec from Tier 0 to tape at Tier 1 with ASGC at 20 MB/sec, CNAF at 50 MB/sec, FNAL at 100 MB/sec, FZK at 30 MB/sec, IN2P3 at 30 MB/sec, PIC at 60 MB/sec and RAL at 20 MB/sec (based on tape pledges in Mou). Would like this to be an SC4 activity.
December Production of 10M events/month requiring 1600 KSi2K. 20% of the CPU resources (320 KSi2K) required at Tier-1 centers. Raw and reconstructed events will be stored on tape at Tier-1. Expected volume in addition to the existing capacity is 25TB. Tier-0 to Tier-1 transfer exercises will continue, with mostly moderate rates at <100MB/s and short bursts up to 600 MB/s. Backup the October CSA06 disk files (CNAF of 160TB, FNAL of 280TB and at each other Tier 1 of 70TB) to new permanent tape storage. Resource expectations at Tier-1 centers are within the limit of pledged computing resources.
