  • Patent number: 8929252
    Abstract: A network switch allows defining a virtual port worldwide name (VPWWN) and associating the VPWWN with an F_port of the network switch, for use by a host bus adaptor (HBA) connecting to the network switch. Both a default and a user VPWWN may be defined, with the user VPWWN typically taking precedence over the default VPWWN. A database of VPWWN associations may be used to ensure uniqueness of the user VPWWN. Where the HBA allows dynamic assignment of WWNs, the VPWWN may be pushed to the HBA. The VPWWNs may be deleted, and moved to another port as desired.
