3.2.2 Connecting a SCSI Array

The SCSI Diamond Storage Array uses a VHDCI connector and SCSI cables to connect to a host. It will automatically detect the type of Host Interface Card it is using without any intervention.

To connect a SCSI array

1Insert a SCSI VHDCI connector into the Host

Interface Card in the back of the array.

2Connect the cable from your host system to one of the VHDCI connectors on the Host Interface Card connector on the back of the array.

3If the SCSI array is the last device on the bus, you must attach a VHDCI terminator to one connector of the SCSI Host Interface Card or

Exhibit 3.2-3 SCSI cable options.

connect a cable between the second connector and the next device on the SCSI bus.

4The SCSI Host Interface Card has a rotary binary-coded hex switch which allows you to set the SCSI ID of the HIC. Be sure the selected ID is different from all other SCSI devices on the bus.

Note

If slower devices are connected on the same SCSI bus as the Ultra 160 array, the bus will communicate at the rate of the slowest device.
