An administrator is configuring a server to communicate with a new storage array. To do so, the administrator enters the WWPN of the new array in the server's storage configuration. Which of the following technologies is the new connection using?
Should be D
Fibre Channel
A very common interface for storage in servers is a Fibre Channel interface. These are used to connect devices in a high-speed fiber storage network. These networks typically use a fiber switch with devices connected to the switch using Fibre Channel interfaces. Servers will require some implementation of a fiber HBA. Each HBA has a unique World Wide Name (WWN), which like a MAC address uses an organizationally unique identifier (OUI) assigned by the IEEE. An example of a fiber switch to which the cables from the HBAs on the servers would attach.
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 an IBM Storage Device has a unique and persistent WWPN.
