Voyager 3000 User Guide

This system will typically be used in similar situations to that described within the VRA- 3001T-XX-Y section on page 1-2 but with larger capacity requirements.

The VRA-3002T-XX-Y is configured as two SCSI buses. The first SCSI channel is connected to the top three drives in the first shelf (left hand side) which are set up as SCSI Ids 0à2. The cable is then routed to the top four drives in the second shelf. These drives are set up as SCSI Ids 3à6. The second channel is connected to the bottom three drives in the first shelf which are configured as SCSI Ids 0à2 and looped to the second shelf to connect to the bottom three drives which are set up at SCSI Ids 3à5. Refer to Figure 1-4 for a schematic view of the interconnects. Each of the systems described are also available with differential host SCSI buses giving an overall host cable length of 25 metres.
