SNMP World Wide Name (WWN)

SNMP

Simple Network Management Protocol.

Speed

A status type in the FC Status Menu showing the speed (1063 Mbps) of the FC adapter.

- T -

Target

A SCSI device (usually the peripheral) that responds to an operation requested by a SCSI initiator (usually the host system). SCSI peripherals are targets, but for some commands (for example, a COPY command), the peripheral may need to act temporarily as an initiator.

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 SCSI adapter’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 physical or logical layout of nodes on a network. FC topologies include point-to-point, FC- AL, and Fabric. The FCR200 supports all topologies.

A status type in the FC Status Menu showing the type of FC topology being used.

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.

- W -

World Wide Name (WWN)

AName_Identifier which is worldwide unique, and represented by a 64-bit unsigned binary value.
