While NPV is similar to N port identifier virtualization (NPIV), it does not offer exactly the same
functionality. NPIV provides a means to assign multiple FC IDs to a single N port, and allows multiple
applications on the N port to use different identifiers. NPIV also allows access control, zoning, and port
security to be implemented at the application level. NPV makes use of NPIV to get multiple FCIDs
allocated from the core switch on the NP port.
