tosca.nodes.nfv.VDU.VirtualStorage
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The NFV VirtualStorage node type represents a virtual storage entity
which it describes the deployment and operational behavior of a virtual
storage resources, as defined by **[ETSI NFV IFA011].**
**[editor note]** open issue: should NFV profile use the current storage
model as described in YAML 1.1. Pending on Shitao proposal (see
NFVIFA(17)000110 discussion paper)
**[editor note]** new relationship type as suggested in Matt
presentation. Slide 8. With specific rules of "valid_target_type"
