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:
“We, too, had good attendance once,
Hearers and hearteners of the work;
Aye, horsemen for companions,
Before the merchant and the clerk
Breathed on the world with timid breath.”
—William Butler Yeats (1865–1939)
““... Farewell then,
Until, under a better sky
We may meet expended, for just doing it
Is only an excuse. We need the tether
Of entering each other’s lives, eyes wide apart, crying.””
—John Ashbery (b. 1927)
“Through the port comes the moon-shine astray!
It tips the guard’s cutlass and silvers this nook;
But ‘twill die in the dawning of Billy’s last day.
A jewel-block they’ll make of me to-morrow,
Pendant pearl from the yard-arm-end
Like the ear-drop I gave to Bristol Molly—
O, ‘tis me, not the sentence they’ll suspend.”
—Herman Melville (1819–1891)
