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:
“If any ambitious man have a fancy to revolutionize, at one effort, the universal world of human thought, human opinion, and human sentiment, the opportunity is his own—the road to immortal renown lies straight, open, and unencumbered before him. All that he has to do is to write and publish a very little book. Its title should be simple—a few plain words—”My Heart Laid Bare.” But—this little book must be true to its title.”
—Edgar Allan Poe (1809–1845)
“If in this wide world, teeming with abundant supplies for human want, to thousands of wretched creatures no choice is open, save between starvation and sin, may we not justly say that there is something utterly wrong in the system that permits such things to be?”
—Tennessee Claflin (1846–1923)
“The very best place to be in all the world is St. Mary’s parish, Jamaica. And the best spot in St. Mary’s is Port Maria, though all of St. Mary’s is fine. Old Maker put himself to a lot of trouble to make that part of the island of Jamaica, for everything there is perfect.”
—Zora Neale Hurston (1891–1960)
