In computing, a World Wide Port Name, WWPN, or WWpN, is a World Wide Name assigned to a port in a Fibre Channel fabric. Used on storage area networks, it performs a function equivalent to the MAC address in Ethernet protocol, as it is supposed to be a unique identifier in the network.

Feb 15, 2022 · WWNN is a specific identifier assigned to a node, while WWPN is a specific identifier assigned to a port. In other words, WWNN is the identifier of the host or storage array, while WWPN is the identifier of a specific port on that host or storage array.

There are two types of WWN address: The WWNN and the WWPN. They both use the same format and look the same. The WWNN World Wide Node Name. The World Wide Node Name (WWNN) is assigned to a host in the storage network. The WWNN signifies that individual host. The same WWNN can identify multiple network interfaces of a single network node.

A WWPN is a World Wide Port Name; a unique identifier for each Fibre Channel port presented to a Storage Area Network (SAN). Each port on an IBM Storage Device has a unique and persistent WWPN.

May 28, 2012 · A WWPN (World Wide Port Name) is physically assigned to a part in a Fibre Channel device, such as a FC HBA or SAN. It is the equivalent of the MAC address in the Ethernet protocol as it is supposed to be a unique identifier in the netwok.

Nov 6, 2018 · wwpn Whereas the WWN is assigned to the device. The World Wide Port Name's (WWPN) is a unique address assigned to every port of a node (be it HBA or storage system).

A WWPN (World Wide Port Name) is a unique identifier for Fibre Channel ports. A WWPN alias is a unique human-readable name for a Fibre Channel port that makes it easier to identify it. You can view, edit, and add WWPNs and WWPN aliases by going to iSCSI & Fibre Channel > Fibre Channel > FC WWPN Aliases.

A worldwide port number (WWPN) is unique identifier for each FC port of any Fibre Channel device. For server , we have a WWPN for each port of the HBA. For a SAN switch , the WWPN is available for each port in the chassis.

What is World Wide Name (WWN)? A World Wide Name (WWN) is a unique identifier that is hard-coded into each Fibre Channel (FC) device by the device's manufacturer. WWNs provide a method for identifying FC devices across the network. Each WWN conforms to one of several formats defined by the Institute of Electrical and Electronic Engineers (IEEE).

Apr 26, 2013 · A WWPN (world wide port name) is the unique identifier for a fibre channel port where a WWN (world wide name) the unique identifier for the node itself. A good example is a dual port HBA. There will be two WWPN's (one for each port) and …
