Tier 1 BNL-Brookhaven. To provide 23% of Atlas resources  
Month Atlas Requirements Tier 0 Requirements
April 2006 Provide 234 KSi2K of cpu for MC event generation and 16 TB of disk and 35 TB of tape for this data for this quarter 3rd to 16th CERN disk-disk at 200 MB/sec. 18th to 24th CERN disk-tape at 75 MB/sec
May Provide 234 KSi2K of cpu for MC event generation. CERN background disk-disk top up to 200 MB/sec
June Provide 234 KSi2K of cpu for MC event generation. From 19 June to 7 July T0 to T1 tests take 76.8 MB/sec "Raw" to tape (rate to be reported), ESD at 100 MB/s to disk and AOD at 20 MB/s to disk from Tier 0 (total rate 196.8 MB/s). These data can be deleted after 24 hours CERN background disk-disk top up to 200 MB/sec
July Provide 253 KSi2K of cpu for MC event generation and 20 TB of disk and 37 TB of tape for this data for this quarter. "Raw" reconstruction setting up - stagein from tape using 1-2 drives. T0 to T1 tests take 76.8 MB/sec "Raw" to tape (rate to be reported), ESD at 100 MB/s to disk and AOD at 20 MB/s to disk from Tier 0 (total rate 196.8 MB/s). These data can be deleted after 24 hours CERN background disk-disk top up to 200 MB/sec
August Provide 253 KSi2K of cpu for MC event generation. Two slots of 3 days of "raw" reconstruction - stagein from tape using 1-2 drives. Analysis tests - 20 MB/sec incoming - will include scalability tests and prefers to be only Atlas grid activity. T0 to T1 tests take 76.8 MB/sec "Raw" to tape (rate to be reported), ESD at 100 MB/s to disk and AOD at 20 MB/s to disk from Tier 0 (total rate 196.8 MB/s). These data can be deleted after 24 hours CERN background disk-disk top up to 200 MB/sec
September Provide 253 KSi2K of cpu for MC event generation. Tier 0 internal tests with T0 to T1 tests take 76.8 MB/sec "Raw" to tape (rate to be reported), ESD at 100 MB/s to disk and AOD at 20 MB/s to disk from Tier 0 (total rate 196.8 MB/s). These data can be deleted after 24 hours CERN background disk-disk top up to 200 MB/sec.
October Reprocessing tests - 20 MB/sec incoming CERN background disk-disk top up to 200MB/sec
November Provide 312 KSi2K of cpu and an additional 3.6 TB of permanent disk and 4.3 TB of temporary (till reconstruction is run) disk plus an additional 6.9 TB of permanent tape storage for MC event generation. Analysis tests - 20 MB/sec incoming at the same time as reprocessing continues CERN background disk-disk top up to 200MB/sec
December Provide 312 KSi2K of cpu and an additional 3.6 TB of permanent disk and 4.3 TB of temporary (till reconstruction is run) disk plus an additional 6.9 TB of permanent tape storage for MC event generation. CERN background disk-disk top up to 200MB/sec
