T0-T1 transfer tests (week1)
T1-T1 transfer tests (week2)
Some summaries presented at ADC Operations Meeting http://indico.cern.ch/conferenceDisplay.py?confId=33976
T0-T1-T2 transfer tests (week3)
General remarks
https://twiki.cern.ch/twiki/bin/view/Atlas/DDMOperationsGroup#CCRC08_2_May_2008
The T0 load generator will run at "peak" rate for 3 days ("peak" rate means data from 24h/day of detector data taking at 200Hz are distributed in 24h, while "nominal" rate means data from 14 hours/day of detector data taking at 200Hz are distributed in 24h).
At peak rate 17,280,000 events/day are produced, corresponding to 27.6 TB/day of RAW, 17.3 TB/day of ESD and 3.5 TB/day of AOD (considering the sizes of 1.6 MB/event for RAW, 1.0 MB/event for ESD and 0.2 MB/event for AOD)
- It turned out that AOD size was 0.1 MB/event; 1.7TB/day.

T0-T1(LYON)
Shipping continuously data to T1s according to computing model, sites should demonstrate to sustain for 3 days the following export rates
| SITE | TAPE | DISK | TOTAL |
| IN2P3 | 48.00 MB/s | 100.00 MB/s | 148.00 MB/s |
Metric for success: Sites should be capable of sustaining 90% of the mentioned rates (for both disk and tape) for at least 2 days of test. For sites who would like to test higher throughput, we can oversubscribe (both to disk and tape).
As a reminder, here the table of the necessary space needed at each T1
| SITE | TAPE | DISK |
| IN2P3 | 12.4416 TB | 25.92 TB |
replication status is checked ~ every 2h http://pandamon.usatlas.bnl.gov:25880/server/pandamon/query?mode=listFunctionalTests
T1-T2
T2s will receive AODs, which should be generated
at a rate of 3.5TB/day 1.7TB/day.
The amount that each site receives depends on the share
as written in

according to dq2.log, new subscriptions today (since 5.22 00:00) are queued only to BEIJING and RO-02-NIPNE, resulting in errors.
the status table does not look nice, I will check. http://panda.atlascomp.org/?mode=listFunctionalTests&testType=T1toT2s#LYON

I tuned the IN2P3-BEIJING channel to 20 concurrent files and 5 concurrent streams. I tested many combinations: Nofiles NoStreams 5 3 10 5 15 5 20 5 20 10 25 5 30 5 It appears that 20/5 is the best for the moment which can reach more than 80MB/s throughput.
