OpenCloud has the design goal to not use a relational database. This requires a deeper integration with the underlying storage system, ie. through extensive use of extended file attributes.

In this talk we will give an overview of the storage aspects that are relevant from OpenClouds perspective, the integrations that we currently support as well as ongoing research topics.
