2.5.2.5 PCI SCSI-2 Adapters
The following two PCI SCSI adapters are supported:
PCI SCSI-2 Single Ended Fast/Wide Adapter (feature #2408)
PCI SCSI-2 Differential Fast/Wide Adapter (feature #2409)
Each adapter occupies one PCI slot, and a maximum of seven adapters can be
installed in the Model F30. Refer to 2.4.2.5, “PCI SCSI-2 Adapters” on page 25 for
technical information about these SCSI-2 Adapters.
As described in 2.5.1, “Standard Features” on page 32, the RS/6000 Model F30
features four media bays, six standard and 12 optional half-height hot-swappable
disk bays. To add six half-height hot-swappable disk bays to the system, additional
hardware is required. This hardware consists of a backplane, a power cable, a PCI
SCSI-2 F/W Adapter, a SCSI cable, and mounting hardware. This kit can be
ordered as a hardware feature named
SCSI 6-Pack #2 Kit (feature #6421) or SCSI
6-Pack #3 Kit (feature #6422), depending on which optional hot-swappable bays
are going to be installed.
Table 9 shows the maximum number of both internal and external devices that can
be attached to a SCSI-2 adapter and related cables for the RS/6000 Model F30.
