WWN Meaning and
Definition
-
WWN stands for World Wide Name. It is a unique identifier used in Fibre Channel (FC) networks to identify a specific port or node within the network. A WWN is a logical address assigned to a Fibre Channel port or node by the manufacturer, and it remains unchanged throughout the lifetime of the hardware.
A WWN consists of a 16-digit hexadecimal number, often divided into two parts: a prefix and a suffix. The prefix, known as the Organizational Unique Identifier (OUI), is assigned by the Institute of Electrical and Electronics Engineers (IEEE) to the manufacturer. This helps ensure that WWNs from different vendors don't overlap. The suffix, on the other hand, is assigned by the manufacturer and is unique to each port or node they produce.
WWNs play a crucial role in the identification and communication process within a Fibre Channel network. They enable devices such as servers, storage arrays, and switches to recognize each other and establish connections. WWNs are also used for zoning and masking in FC networks, which determine access control and visibility between devices.
Overall, WWNs provide a means for identifying and addressing specific components within a Fibre Channel network, promoting efficient and reliable communication between these devices.
