No, I do not have a problem with that. My point is that the very same facility that provides the tape may at the same time control the disk: the disk would just be the online component of the tape store, and not something that one has to foresee separately, if desired.
Isn't that the point of having the Resource? That represents the management system, and is linked to N Datastores each of which represents a homogeneous pool of storage. You can choose not to publish some or all of the Datastores, but I don't see any gain from merging them together, it would just take us back to the complexity we're trying to disentangle (i.e. what kind of physical storage is used where).
