their relationship to the SCSI ID orientation.
The 4-slot and 6-slot backplane provide SCA-2 connector type for direct
connection of the disk carrier.
Table 7-3 and Table 7-4 how the slot numbering for the 4-slot and 6-slot
backplanes. The SCSI ID for disk drives is preset on the backplane with the

IDs for a vertically installed storage cage for the storage subsystems.
