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
January 2007 Provide 416 KSi2K of cpu each month and an additional 14.3 TB of permanent disk plus an additional 27.5 TB of permanent tape storage for this quarter for MC event generation. CERN background disk-disk top up to 200MB/sec
February Provide 416 KSi2K of cpu for MC event generation. From 26 Feb begin 4 week data distribution tests. Rampup to full 2008 rate from Tier 0 during first week. Raw from Tier 0 to reach 74 MB/s, ESD to reach 200 MB/s and AOD to reach 20 MB/s. Raw data to go to tape then can be recycled. ESD and AOD to go to disk and can be recycled but during last two weeks AOD should be distributed to associated Tier 2, requiring up to 5.2 TB of disk buffer, before being recycled. CERN background disk-disk top up to 200MB/sec
March Provide 416 KSi2K of cpu for MC event generation. Continue 4 week data distribution tests till 26 March then participate in all-experiment service challenge milestone taking 65% of the average 2008 rate as in February but without AOD redistribution for the next 7 days. CERN background disk-disk top up to 200MB/sec
April Provide 831 KSi2K of cpu each month and an additional 28.7 TB of permanent disk plus an additional 34.5 TB of permanent tape storage for this quarter for MC event generation.
