I had to investigate OGC's WCS standard and in the process I learned about Rasdaman, a geospatial radar data manager software which is apparently the only software that currently support WCS 2.0 both as a server and client. Rasdaman exists both in a commercial 'rasdaman enterprise' version and as open source with the 'rasdaman community' version. We never really mentioned rasdaman before.
The rasdaman community introduction: "Rasdaman extends standard relational database systems with the ability to store and retrieve multi-dimensional raster data ( arrays) of unlimited size through an SQL-style query language. On such sensor, image, or statistics data appearing, e.g., in earth, space, and life science applications rasdaman allows to quickly set up array-intensive services which are distinguished by their flexibility, speed, and scalability.
