Other Requirements as a Regional Computing Center
Software Environment
- Software environment of the CC-J should be compatible to the PHENIX Offline Software environment at the RHIC Computing Facility (RCF) at BNL
- AFS accessibility (/afs/rhic)
- Objectivity/DB accessibility (replication to be tested soon)
Data Accessibility
- Need exchange data of 225 TB/year to RCF
- Most part of the data exchange will be done by SD3 tape cartridges (50GB/volume)
- Some part of the data exchange will be done over the WAN
- CC-J will use Asia-Pacific Advanced Network (APAN) for US-Japan connection
- APAN has currently 70 Mbps bandwidth for Japan-US connection
- Expecting 10-30% of the APAN bandwidth (7-21 M bps) can be used for this project:
- 75-230 GB/day ( 27 - 82 TB/year) will be transferred over the WAN
