What is WWN and WWPN?

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 a Storage Device has a unique and persistent WWPN. A World Wide Node Name, WWNN, or WWnN, is a World Wide Name assigned to a node (an endpoint, a device) in a Fibre Channel fabric.

What is WWN in Fiber Channel?

World Wide Name
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.

What does WWN stand for?

What is HBA WWPN?

If you plan to commission a partition image to a boot volume on an external storage device, you need to identify the HBA ports of your Partitionable Enterprise Partition Platform (PEPP) that will be allocated to the partition, as well as the initiator World Wide Port Name (WWPN) of the HBA ports, and provide the …

What is WWPN number?

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. For Storage, each host port has an individual WWPN.

Does WWNN and WWPN are the same?

WWPN is a 64-bit physical address of FC port (interface) and WWNN is a 64-bit physical address of HBA itself.

What is WWN address?

The world wide name (WWN) is a 64-bit address that identifies a fabric or an entity (such as an FC switch, node, or port) in an FC SAN. The upper-layer protocol of FC uses WWNs for communication. Each entity has a factory-assigned globally unique WWN.

Does Sata have WWN?

for scsi all of the above is obtainable by a scsi inquiry. for SATA drives I use HDIO_GET_IDENTITY ioctl to obtain model,serial and revision but it doesnt include WWN.

What are HBA cards?

What is a Host Bus Adapter (HBA)? An HBA is a circuit board or expansion card that physically connects a host system, such as a server, to internal and/or external storage, such as hard disk drives (HDDs), Solid State drives (SSDs), and external storage enclosures.

Where can I find WWPN in Windows?

Finding a WWN on a Windows host
