Minimum requirements The Open Archive is an optional 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 requirementsOpenArchive 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://nlen.wikipedia.org/wiki/Redundant_array_of_independent_disks) RAID) with ample capacity 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- OS minimum +3 GB RAM.
- OS minimum +3 CPUs.
- See Tomcat requirements.
- Load balancers must use sticky sessions.
- Permissions
- The archive is a web application running inside a tomcat web server. 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
Deltares - Archive Server with full permissions.
- Must be accessible by the Forecasting Shell Servers with write permissions.
