In this configuration (from the front of the expansion cabinet), the following occurs:

Controller module A controls the right side of disk arrays 1 through 3 and all of disk arrays 4 and 5.

Controller module B controls the left side of disk arrays 1 through 3 and all of disk arrays 6 and 7.

This configuration is shown in FIGURE 3-17.

3.1.3.3SCSI Jumper Cables and Terminators

The top four StorEdge D1000 disk arrays should have SCSI jumper cables between the middle SCSI connectors (IN/OUT-1 and IN/OUT-2) and a differential SCSI terminator in the far right SCSI connector (IN/OUT-2).

The bottom three StorEdge D1000 disk arrays should have differential SCSI terminators on the inside IN/OUT-1 and IN/OUT-2 SCSI connectors. This configuration is shown in FIGURE 3-17.
