Excerpt

The Deltares Open Archive is an optional component for Delft-FEWS. It is a web application running in Optional server running as a Tomcat servlet container that stores for storing forecast data, performance indicator data and configurations on a longer time scale than in the central database of the Delft-FEWS system.

Hardware requirements

The Deltares Open Archive poses modest requirements to host hardware:

  • Storage. The most important requirement for the file system is that it keeps on functioning after the failure of a single disk. Any RAID (https://nl.wikipedia.org/wiki/Redundant_array_of_independent_disks) will be sufficient.
  • Memory. The server should have at least 4 GB memory available for the Elastic Search catalogue and the Tomcat instance which hosts the archive server.
  • CPU. The speed of the catalogue (searching in the archive) depends heavily on the CPUs of the server. It is recommended to have at least 4 CPUs available.

Software requirements

  • Tomcat 9
  • Both linux and Windows are supported
  • Required permissions for the file system containing archive data:
    • Must be accessible by the THREDDS server with read permissions.
    • Must be accessible by the Archive Server with full permissions.
    • Must be accessible by the Forecasting Shell Servers with write permissions.
