ADIC FCR 200 Mapping Table, Multiplexer, Motherboard, NPort Identifier, Node Name, Offline

Mapping Table POST

Mapping Table

A table which is indexed by sequential LUN values, indicating selected BUS:TARGET:LUN devices. It is used by the FCR200 to perform Fibre Channel-to-SCSI operations by default.

MIB

See Management Information Base (MIB) on page gl-3.

Multiplexer

A device that allows two or more signals to be transmitted simultaneously on a single channel.

Motherboard

The main PCA of the FCR200 that provides a physical and logical connection between Fibre Channel and SCSI devices.

N_Port

AFC term defining 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.

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 64-bit value, the factory assigns to the FCR200.

Offline

Taking the FCR200 offline indicates that all SCSI and FC adapters in the FCR200 are offline.

Taking a SCSI adapter offline means ending inputs/outputs and suspending all transactions going from the FCR200 to the specified SCSI devices. The SCSI adapter is no longer active or available for access.

Taking a FC adapter offline means ending inputs/ outputs and suspending all transactions going from the FCR200 to the specified FC device.

Online

For the FCR200, online indicates that at least one adapter in the FCR200 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.

For a FC adapter, online indicates the FC adapter is active and available for access and input/output processing.

Originator

The Fibre Channel N_Port responsible for starting an exchange. A FC originator is comparable to a SCSI initiator.

- 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 FCR200 supports all topologies.

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.

POST
