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
A menu item. The auto-addressing option creates a mapping table using devices discovered upon powering
up or resetting the PowerVault 35F that is not otherwise retained by the PowerVault 35F.
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
.
Channel
A general term for a path on which electronic signals travel.
