WWN

WWN is an acronym with multiple meanings across different fields. The most common usage in information technology refers to World Wide Name, a unique identifier used in Fibre Channel storage area networks (SANs). In this context, devices such as hosts, storage targets, and interfaces are identified by 64-bit World Wide Names. There are two related identifiers: World Wide Node Name (WWNN) and World Wide Port Name (WWPN). WWNs are typically assigned by the device manufacturer or the network administrator and are presented as hexadecimal strings. They are persistent identifiers that enable SAN services such as zoning, LUN mapping, and pathing, independent of any IP addressing scheme used in other layers of the network.

In professional wrestling, WWN stands for World Wrestling Network, a promotion network and streaming platform that consolidates a group of independent wrestling promotions and events under a common brand. WWN Live operates as a distribution and event promotion platform for independent wrestling, providing live events and online content to fans. This usage is unrelated to Fibre Channel technologies and reflects a separate entertainment business model focused on live performance and media distribution.

Because WWN is an acronym used in different domains, context is important to determine its intended meaning. In technology discussions, it almost always refers to World Wide Name in SAN environments, while in wrestling or media contexts it more likely denotes World Wrestling Network.
