N_Port ID virtualization (NPIV)
N_Port ID virtualization (NPIV) is a technology that defines how multiple virtual servers can
share a single physical Fibre Channel port
identification (ID).
NPIV allows a single host bus adaptor (HBA) or target port on a
storage array to register
multiple World Wide Port Names (WWPNs) and N_Port identification numbers. This allows each virtual server to
present a different world wide name to the storage area network (SAN), which in
turn means that each virtual server will see its own storage -- but no other virtual server's
storage.
