Glossary 135

switched fabric

A FC term describing a switched topology, which is one of the three existing

FC topologies. Fabric elements interconnect various N_Ports or NL_Ports and

are responsible for frame routing.

Transmission Control Protocol/Internet Protocol

target

A device (usually a peripheral) that responds to an operation requested by an

initiator (usually a host system). Peripherals are targets, but for some

commands (for example, a SCSI COPY command), the peripheral may need to

act temporarily as an initiator.

target mode

Configuration mode of the storage router in which a SCSI initiator requests

operations to be performed by a Fibre Channel target device.

terminator block/

termination

An electrical connection at each end of the SCSI bus composed of a set of

resistors (or possibly other components). Its function is to provide a pull-up for

open collector drivers on the bus, and also impedance matching to prevent

signal reflections at the ends of the cable.
The SCSI bus requires termination at both ends of the bus. One end of the

SCSI bus is terminated by the interface card’s internal termination. The other

end should have a terminator placed on the 68-pin high density SCSI

connector on the last SCSI peripheral. If this device is not terminated, data

errors may occur.

topology

The logical and/or physical arrangement of stations on a network.

trap

In the context of SNMP, an unsolicited message sent by an agent to a

management station. The purpose is to notify the management station of some

unusual event.

V

view node name

A status type in the FC Status menu showing the identification of the node.

view port name

A status type in the FC Status menu showing the identification of the port.
