Input/Output (I/O) Module
Two I/O modules are mounted in the rear of the system utilizing Ultra-3 SCSI interfacing
with the host computer system. Two I/O module configurations are available, as follows:
•
The 1 x 8 configuration is used to create a SCSI bus structure with one string of 8
drives. It consists of one standard I/O module with two VHDCI connectors for
main I/O purposes and a switch to set the SCSI-ID range. The second module is a
loopback PCB with no external connectors.
•
The 2 x 4 configuration is used to create a SCSI bus structure with two strings of 4
drives. The two modules are the standard I/O modules with two VHDCI
connectors for main I/O purposes.
Figure 1-11 shows a standard Ultra-3 I/O module.
