1.3 System Configuration
Figure 1.8 shows the system configuration. The IDDs are connected to the SCSI bus of host
systems and are always operated as target. The IDDs perform input/output operation as
specified by SCSI devices which operate as initiator.
Figure 1.8 System configuration
(1) SCSI bus configuration
Up to eight SCSI devices operating as an initiator or a target can be connected to the SCSI bus
for the 8-bit SCSI and up to 16 SCSI devices operating as an initiator or a target can be
connected to the SCSI bus for the 16-bit SCSI in any combination.
For example, the system can be configured as multi-host system on which multiple host
computers that operate as initiator or connected through the SCSI bus.
Using disconnect/reconnect function, concurrent input/output processing is possible on multi-
SCSI devices.
