You partially correct. Background operation may be applicable to any resource
or thin provisioned device. For a fully provisioned device there is never an
issue of resources being depleted, so the model clause does not apply. For
stream operation since we allow a resource provisioned device to become thin
provisioned at some point this should apply to both thin and resource
provisioned. I am not sure on this about fully provisioned since a fully
provisioned device is not managing allocation of resources. I will modify
both of these clauses to include thin provisioned. If you believe fully
provisioned should be included, I would like to have further discussion.

Why does the storage intelligence restrict the Background Operation Control
and Write Stream to only Resource Provisioned devices, when there could be
value if it was used for both Thin and Thick Provisioning?
