Handling heterogeneous storage devices in clusters

This tutorial presents the concepts that lay behind the most successfully applied ideas to manage heterogeneous storage devices in cluster environments. Among these ideas we can point out storage virtualization that can either be coupled with deterministic mechanisms to optimize heterogeneous disk usage or with randomization techniques. Focusing on the concepts instead on the real implementations and/or systems (like it is normally done) has the advantage that the attendees get a much clearer view of the ideas presented and enables the attendees to transfer the ideas to their own fields.
