A SCSI or RAID type PCI card must be installed in a PCI slot in an I/O module to act as the controller of the storage module. A PCI card is combined with a storage module, as shown in Figure 25, by connecting the SCSI cable from the PCI card to the SCSI connector on the same I/O module, and then connecting the board wiring from the SCSI connector to server slot #4 to #7, where the storage module is installed through the backplane. The logical numbers of the SCSI connectors on I/O module #0 and #1 are defined as #0 to #1 and #2 to #3, respectively.
