DATE Performance Test
Biggest complete DATE run ever done: 20 TB to tape
Event building performance test (see plots in the 3 following slides)
- Event building over Fast and Gigabit Ethernet, link aggregation
- Event building only, no data recording
- ~ 10% of ALICE DAQ
Raw performance with realistic data traffic
- 22 LDC with realistic sub-event size from 11 detectors
- Relative sub-event size : 1 to 20
- 11 GDC
- Duration: 43 hours
- Average rate: 355 MB/s Total data volume: 54 TB
Scalability test:
- Aggregate throughput as a function of # GDC (1 to 15) for a given # LDC
Top performance test
- Duration: 1 hours
- Average rate: 555 MB/s Total data volume: 1.8 TB
