News: Fs Data Management, Eiger Server/Controller

• Fs Data Management: new demanding detectors forced us to reconsider our data management strategies. In collaboration with IT a note has been prepared proposing several measures which are currently being discussed:

  Summary:

  • the data-on-disk time will be limited to 90 days after the beamtime as ended.

  • the beamline file system will no longer store complete beamtimes. Instead this server will act as a pass-through buffer for data to be moved to the core file system.

  • a substantial upgrades of the FS-related IT infrastructure of the computer center are needed.

  • storage demands may become part of the proposal evaluation

  • maturity of the data analysis pipeline may also be considered during the proposal evaluation

  • the purchase of new detectors has to be reviewed for impact on data volumes.

• Eiger: server/Controller: the EigerDectris server and the pool controller have now been tested under Debian-9/Eiger1, Debian-9/Eiger2 and Debian-10/Eiger2 on haspp07eh2, haspp08, haspp10lab, hasnp62.
