3.1.3.2 Module ID Switch
Ensure that the module IDs for the StorEdge D1000 disk arrays are set according to
TABLE 3-3 .
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 .
3.1.3.3 SCSI 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 .
