Open Archive
The webserver Open Archive is an optional server that hosts and distributes the webpages generated by component for Delft-FEWS 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.
Software requirements
- The archive is a web application running inside a tomcat web server. Both Linux and Windows are supported.
Required permissions
The file system containing archive data:
- Must be accessible by the THREDDS server with read permissions.
- Must be accessible by the Deltares Archive Server with full permissions.
- Must be accessible by the Forecasting Shell Servers with write permission
Webserver
The webserver is an optional server that hosts and distributes the webpages generated by Delft-FEWS. Hardware requirements depend on the intended use.
PiService
This is an optional service
PiService
This is an optional service which allows SOAP clients to interact with and retrieve data from the Delft-FEWS system. Hardware requirements depend on the intended use. In general it is not recommended to have the PiService on the same machine as the master-controller.
