108 Glossary
Light Emitting Diode, a commonly used semiconductor device that glows
when supplied with a specified voltage.
For Fibre Channel, it is a connection between two nodes, each having at
least one N_Port, interconnected by a pair of optical or copper links, one
inbound and one outbound.
The process where the Scalar Library uses the Media Picker to pick a
cartridge from either a cartridge storage slot location, or from the Virtual
Mailbox slot and load it into a drive.
Lasers or LEDs that emit light with wave lengths around 1300 nm. Long
wave lasers are used for long Fibre Channel links, from ~700 to 2000 m.
They are typically used with single-mode fiber of a 9-micron core size.
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 Loop Address of the FC-SCSI MUX.
A N_Port or F_Port that supports arbitrated loop functions associated with
arbitrated loop topology.
Logical Unit Number or Logical Unit; a subdivision of a SCSI target. For
SCSI-2, each SCSI target supports up to eight LUNs (LUN-0 to LUN-7).
Using LUNs, the host can address multiple peripheral devices that may
share a common controller.
Power-On Self-Test is a built-in self-test for the DLT drive. POST
automatically occurs each time the Scalar Library powers up.
A "Node" port. A FC-defined hardware entity that performs data
communication over the FC link. It is identifiable by a unique Worldwide
Name. It can act as an originator or a responder.
A unique address identifier by which a 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.
A field value under the FC Status Menu. The unique identifier, a 64-bit
value, the factory assigns to the FCR100. For more detailed information,
see N_Port or N_Port Identifier.
The Fibre Channel N_Port responsible for starting an exchange. A FC
originator is comparable to a SCSI initiator.
One of three existing FC topologies, in which two ports are directly
connected by a link with no fabric, loop, or switching elements present.
The FCR100 supports only loop topology.
The logical function in a N_Port responsible for supporting the exchange
initiated by the originator in another N_Port. A FC responder is
comparable to a SCSI target. The FCR100 is often the responder.
