Deltares Open Archive requirements

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

Hardware requirements

OpenArchive 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 elasticsearch 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.
