The ASAP3 storage is divided into two GPFS file-systems; the beamline file-system and the core file-system. The beamline file-system is optimised for the ingestion of data in high speed bursts, while the core file-system has been optimised for capacity and parallel concurrent access. 

Data taken during a beamtime is first written to the beamline file-system, and is then concurrently synced to the core file-system from where it can be accessed and analysed with a delay of a few minutes. Once the beamtime is stopped, the data corresponding to this beamtime can only be accessed from the core file-system.
