132 Glossary
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.
narrow SCSI 50-pin SCSI connector; can be single-ended or differential in implementation.
non-OFC An acronym for Non Open-Ended Fibre Control. This approach does not drop
the laser power when a cable link is dropped. Non-OFC uses a lower power
laser than an OFC system.
O
OFC An acronym for Open-Ended Fibre Control. When a cable link is dropped, the
laser drops, to eliminate the potential for eye damage.
offline Taking the Interface Manager offline indicates that all SCSI and FC adapters
in the Interface Manager are off-line. Taking an interface card offline means
ending inputs/outputs and suspending all transactions going from the
Interface Manager to the specified SCSI devices. The interface card is no
longer active or available for access.
online For the Interface Manager, online indicates that at least one adapter in the
Interface Manager is active and available for access. For a SCSI adapter,
online indicates the SCSI adapter is active and available for access and
input/output processing.
originator A Fibre Channel term that refers to the initiating device.
P
Point-to-Point 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 FC 2/1 LV
and FC 4/1 HV use FC-AL to support Point-to-Point configurations.
port The hardware entity within a node that performs data communications over
the Fibre Channel link.
port name A field value under the FC Status menu; the FC port identifier; a 64-bit value
the factory assigns to each FC adapter.
PPP An acronym for Point-to-Point Protocol. A transmission path over which data is
transmitted between two Fibre Channel devices.
