In computing, a World Wide Port Name, WWPN, or WWpN, is a World Wide Name assigned to a port in a Fibre Channel fabric. Used on storage area networks, it performs a function equivalent to the MAC address in Ethernet protocol, as it is supposed to be a unique identifier in the network.
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. It is valid for the same WWNN to be seen on many different ports (different addresses) on the network, identifying the ports as multiple network interfaces of a single network node.
Famous quotes containing the words world, wide and/or port:
“For in all the world there are no people so piteous and forlorn as those who are forced to eat the bitter bread of dependency in their old age, and find how steep are the stairs of another man’s house. Wherever they go they know themselves unwelcome. Wherever they are, they feel themselves a burden. There is no humiliation of the spirit they are not forced to endure. Their hearts are scarred all over with the stabs from cruel and callous speeches.”
—Dorothy Dix (1861–1951)
“[In early adolescence] she becomes acutely aware of herself as a being perceived by others, judged by others, though she herself is the harshest judge, quick to list her physical flaws, quick to undervalue and under-rate herself not only in terms of physical appearance but across a wide range of talents, capacities and even social status, whereas boys of the same age will cite their abilities, their talents and their social status pretty accurately.”
—Terri Apter (20th century)
“In the midst of this chopping sea of civilized life, such are the clouds and storms and quicksands and thousand-and-one items to be allowed for, that a man has to live, if he would not founder and go to the bottom and not make his port at all, by dead reckoning, and he must be a great calculator indeed who succeeds.”
—Henry David Thoreau (1817–1862)
