The datacentric infrastructure

The CINES offers public laboratories, offices and agencies, a powerful data storage service.
The datacentric architecture hosted at CINES tends to meet the users’ needs to share their data. This feature can be delivered to users thanks to a set of technical means presented to users as a huge disk space with good performances.

Moreover thoose software and hardware means allow to secure data that are store on this architecture. Thus, sharing thoose technical means offers a high securisation level to every project that have access to this infrastructure.

 

This architecture offers on one side a 2PB secured Lustre filesystem with a cumulated bandwidth of 50 GB/s, and on the other side CXFS filesystems through a NFS export.

Occigen accesses to this filesystem thanks to 12 Lustre gateways connected to an Infiniband FDR fabric. An NFS export is also provided to other machines connected to the 10 Gb/s Ethernet network.

A hierarchical storage management allows disk usage optimization. Files’ data is automatically moved on tapes in two distinct libraries after a given time. This hierarchical management offers two main benefits:

This hierarchical management is seamless for the user: the whole set of files is visible even if their data is on tape. However, user must be aware that latency may occur when accessing “old” files for which data may have been migrated on tapes.

Data is secured once a day on tapes. Copies are kept one week after a deletion occurs. Once the copy process is completed, we are able to restore an accidentally deleted file (if the retention period allows doing so).

Our data infrastructure is based on many items:
