indexed addressing | A menu name. It allows for generic Fibre Channel host bus adapters to access SCSI devices |
| attached to the interface card using a table which is indexed by sequential LUN values. |
initiator | A device (usually a host system) that requests an operation to be performed by another device |
| known as a target (usually a peripheral). |
initiator mode | Configuration mode of the interface card in which a Fibre Channel initiator requests operations |
| to be performed by a SCSI target device. |
IP | Internet protocol |
link | For Fibre Channel, it is a connection between two nodes, each having at least one N_Port (or |
| the other end could be an |
| inbound and one outbound. |
longwave | Lasers or LEDs that emit light with wave lengths around 1300 nm. When using single mode (9 |
| nm) fibre, longwave lasers can be used to achieve lengths greater than 2 km. |
loop address | A FC term indicating the unique ID of a node in Fibre Channel loop topology, sometimes |
| referred to as a Loop ID. Also a status type in the FC Status Menu, showing the FC Loop |
| Address of the interface card. |
loop port (nl_port) | A FC port that supports loops. |
LUN | Logical Unit Number or Logical Unit; a subdivision of a SCSI target. For |
| target supports up to sixteen LUNs |
| multiple peripheral devices that may share a common interface card. |
LVD/SE | Low Voltage |
mapping table | A table which is indexed by sequential LUN values, indicating selected BUS:TARGET:LUN |
| devices. It is used by the interface card to perform Fibre |
| default. |
MB | megabyte. (There are 8 bits in a byte.) |
motherboard | The main PCA of the interface card that provides a physical and logical connection between |
| Fibre Channel and SCSI devices. |
multiplexer | A device that allows two or more signals to be transmitted simultaneously on a single channel. |
N_port | A FC term defining a “Node” port. A |
| communication over the FC link. It is identifiable by a unique Worldwide Name. It can act as |
| an originator or a responder. |
N_port identifier | A FC term indicating a unique address identifier by which an N_Port is uniquely known. It |
| consists of a Domain (most significant byte), an Area, and a Port, each 1 byte long. The N_Port |
| identifier is used in the Source Identifier (S_ID) and Destination Identifier (D_ID) fields of a FC |
| frame. |
node name | A field value under the FC Status Menu. The unique FC identifier, a |
| assigns to the interface card. |
