1.3System Configuration

1.3System 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.
