Dear VMware Experts,
Need to know What is WWN and WWPN number?? and the difference between these two ?
Regards
Mr VMware
WWN - World Wide Name is a unique identifiers on a Fiber Channel nettwork similar to the MAC address of an ethernet network-
WWPN - World Wide Port Name is another name for the WWN assigned to the port on FC fabrice
and to add -
WWNN - World Wide Node Name is a WWN assigned to a node (an endpoint or device_ on the FC Fabric -
Hi,
What is WWN and WWPN number??
In Fibre Channel networks,
A WWN may be used as a WWNN (World Wide Node Name) to identify a switch,
A WWPN (World Wide Port Name) to identify an individual port on a switch
Hi,
A WWPN (World Wide Port Name) is physically assigned to a part in a Fibre Channel device, such as a FC HBA or SAN. It is the equivalent of the MAC address in the Ethernet protocol as it is supposed to be a unique identifier in the netwok.
The WWN’s are administred by the IEEE like the MAC Address is. The first few octets are assigned to a manafacturer, the rest is arbitrary.
The difference between a node WWN (WWNN), is it can be shared by some or all ports of a device, and a port WWN (WWPN), is one which is necessarily unique to each port.
