Indexed Addressing - ADIC FCR 200 Operator's Manual

The SCSI bus

the physical SCSI
port on the back
of the FCR200.

5-6 Understanding the Configuration
Auto Addressing
SCC Addressing
SCSI Targets are selected by mapping the appropriate values
into the FCP LUN field, and correlating a Fibre Channel LUN
value to a SCSI Bus:Target:LUN value. The FCR200 acts as a
single initiator on each SCSI bus, defaulting to ID 7. All
commands passed through to a SCSI bus originate from this
SCSI ID.
As an example, SCSI bus 0 corresponds to SCSI port 0 on the
rear of the FCR200. SCSI bus 1 corresponds to SCSI port 1.
Indexed Addressing allows for generic Fibre Channel host
bus adapters to access SCSI devices attached to the FCR200.
This is done by use of a table which is indexed by sequential
FCP LUN values, indicating selected BUS:TARGET:LUN
devices.
