1.3 System Configuration
An optical disk drive connected to the system SCSI bus always operates as a target. Figure 1.5 is
a system configuration example. Through the SCSI bus, the optical disk drive executes the
input-output operation specified by the SCSI device that operates as the initiator.

1.3.1 SCSI bus configuration
A maximum of eight SCSI devices can be connected to the SCSI bus. The combination of an
SCSI device operating as an initiator and an SCSI device operating as a target is arbitrary. A
multihost system can be configured in which several host systems operate as initiators.
The disconnect or reconnect function enables input-output processing in parallel through more
than one SCSI device.
