Adapter Device

- A -

Adapter

A printed circuit assembly that translates data between the FC host processor’s internal bus and a different bus, such as SCSI.

Address

See SCSI Addressing.

Addressing Mode

Used to create a mapping table that maps devices on the SCSI bus to Fibre Channel logical units.

AL_PA

Arbitrated Loop Physical Address. A unique one- byte valid value, derived and used in an Arbitrated Loop Topology as defined in ANSI specification FC_AL ver 4.5.

Arbitrated Loop

See Fibre Channel - Arbitrated Loop. (ANSI specification FC_AL ver 4.5).

Area

The second byte of the N_Port Identifier.

Auto-Assigned Mapping

Amenu item. The auto-addressing option creates a mapping table using devices discovered upon powering up or resetting the FCR200, that is not otherwise retained by the FCR200.

- B -

Baud

The unit of signaling speed, expressed as the maximum number of times per second the signal can change the state of the transmission line or other medium (units of baud are sec-1). Note: With

Fibre Channel scheme, a signal event represents a single transmission bit.

Bus

A means of transferring data between modules and adapters or between an adapter and SCSI devices. For a SCSI bus definition, see SCSI Bus.

- C -

Channel

A general term for a path on which electronic signals travel.

Clusters

Two or more computers sharing the same resources on a communication link.
