What is a World Wide Name (WWN)?

What is a World Wide Name (WWN)? A World Wide Name, or WWN, is a 64-bit address used in fibre channel networks to uniquely identify each element in a Fibre Channel network.

Learn about FC and FCoE zoning with ONTAP systems

Zoning based on World Wide Name (WWN) specifies the WWN of the members to be included within the zone. Although World Wide Node Name (WWNN) zoning is possible with some switch vendors,

Using Soft WWNs for Fibre Channel Ports

The Soft WWN feature lets Fibre Channel ports use substitute WWNs, allowing HBAs to be replaced without reconfiguring virtual disk assignments. This reduces downtime and simplifies HBA replacement.

wwnAddress

Binds an FC Port ID to a device WWN. Use this command to manage address assignments for a given device world wide name. The allocation of a PID to a specified device WWN supports the persistence

Configuring Fibre Channel Interfaces

Fibre Channel over Ethernet (FCoE) encapsulation allows a physical Ethernet cable to simultaneously carry Fibre Channel and Ethernet traffic. In Cisco Nexus 5000 Series switches, an FCoE-capable

Fibre Channel addressing – storagefreak – storage & cloud blog

All FC devices have a unique identity that is called a worldwide name (WWN). This identification can be compared with Ethernet cards and MAC addresses. Each Node Port has its own WWN, but it is also

The difference between WWN, WWNN and WWPN

Every Fibre Channel device has a unique identifier called WWN (world wide name), which is assigned by IEEE. When multiple hosts use the disk array, use the WWN number to determine which host is

WWN-Based PID Assignment

When the device logs in to the switch, the PID is bound to the device WWN. If the device is moved to another port in the same switch, or a new blade is hot-plugged, the device receives the same PID

Cisco Nexus 5000 Series NX-OS Fibre Channel Command Reference

To configure a WWN for a suspended Virtual SAN (VSAN) that has interop mode 4 enabled, use the wwn vsan command. To discard the configuration, use the no form of this command.

Should I use the WWN or WWPN when zoning an FC switch?

I''m just trying to figure out whether to use the WWN or WWPN when adding devices to a zone. I understand that the WWN identifies a device and the WWPN a specific port. In simplified form lets
