Data Storage and Archive

Storage Locations

Continuum (Mapping , Pointing, Focus etc) and Spectroscopy is acquired on the be4 computer:

  • The data from the FitsWriter is stored to /daten/mbfits. (for details on MBFITS see Multi-Beam FITS Raw Data Format Convention)
  • Logging information for the observed scans is stored in the mySQL observation database.
  • Spectroscopy data is processed with the spectroscopy pipeline on the computer be4 and stored in /daten/Class. (also see GILDAS/CLASS)
  • /daten is a NAS exporting 255 TB of disk space.

Storage and Archive Access

  • The Effelsberg NAS is mounted as /effelsbergData to the local servers (be2, observer4, observer[6-10]) in the local data network 10.200.200.*.
  • The data is moved to monthly folders after 30 days (e.g. /daten/mbfits/mbfits-2026-04/).
  • be2 syncs every 20 min these directories to /eff/data. This volume is accessible in the MPIfR network as a NFS3 mount. Due to the limited storage we will delete data after several years. (possibly outdated info - needs update)
  • After one year the data is copied into the tape library. It is accessible in the MPIfR network at the location /hsm/effarchive. The data is archived to tape. This is a NFS4 mount. You need a kerberos certificate to access it, via kinit from your computer connected to the institute LDAP account system. (posibly outdated info - needs update)

The data is accessible via observer2 via rsync+ssh, scp using the obseff account. This computer is also accessible from the guest network in Effelsberg via observer2g (outdated - needs update)
