Storwize V7000 Gen3 Worldwide node and port names
A worldwide name is a unique name that is composed of 16 hexadecimal digits that are allocated to a node, service, or port on the SAN. A worldwide name that is allocated to a node is called a worldwide node name (WWNN). A worldwide name that is allocated to a port or other SAN service is referred to as a worldwide port name (WWPN).
The WWNN has the following format, where xxxx is a unique number that was assigned when the enclosure was manufactured:
500507681000xxxxThe WWPNs are derived from the WWNN of the node canister in which the ports are installed. The
WWPNs are also derived from the PCIe slot and the port ID on the adapter. When N-Port ID
Virtualization (NPIV) is enabled, each WWPN also has an NPIV WWPN value that should be used for
communications with hosts. Table 1 summarizes the
different WWPN values per port.

When a host is cabled directly to a Fibre Channel port of a Storwize® V7000 2076-724/U7B node canister, other similarly-formatted WWPNs are exposed by the Fibre Channel services that are necessary for direct attachment.
