Hi Carsten,

Here is the database system used by ROCKS:

http://www.rocksclusters.org/rocks-documentation/reference-guide/4.1/database.html

Rocks is an open-source Linux cluster distribution that enables end users 
to easily build computational clusters, grid endpoints and visualization 
tiled-display walls.

Cheers,
 	Bruce
