Project summary : preserve a complete copy of CDF data and MC samples at CNAF + services (access, data analysis capabilities)
The project can be pslitted in two :
- data transfer and preservation
- analysis framework preservation
Data transfer and preservation
To transfer data from FNAL to CNAF has been used Sequential Metadata Access (SAM), developed at Fermilab, installed on a dedicated machine at CNAF.
1) CNAF requests data from FNAL that are staged at FNAL cache
2) Data are copied via gridftp protocol, in a third party transfer, and SAM control the checksum
3) Once the data are in the CNAF cache, they are automatically migrated to tape
