OpenPower 720 Technical Overview and Introduction
integrated USB ports, or to a USB adapter (FC 2738). A maximum of one USB diskette drive
is supported per integrated controller/adapter. The same controller can share a USB mouse
and keyboard.
1.3.5 I/O drawers
The OpenPower 720 has five internal PCI-X slots, where four of them are long slots and one
is a short slot. If more PCI-X slots are needed, especially well-suited to extend the number of
LPARs and Micro-Partitions, up to eight Model 7311 Model D20 I/O drawers can be attached
to the rack-mount OpenPower system. Up to four Model D20 drawers can be connected to the
two RIO-2 ports on the rear of the system that are provided in a minimum configuration. An
additional four Model D20s can be connected by ordering the Remote I/O expansion card (FC
1806). It provides two RIO-2 ports located on a interposer card that occupies the short PCI-X
slot.
7311 Model D20 I/O drawer
The 7311 Model D20 I/O drawer is a 4U full-size drawer, which must be mounted in a rack. It
features seven hot-pluggable PCI-X slots and optionally up to 12 hot-swappable disks
arranged in two 6-packs. Redundant, concurrently maintainable power and cooling is an
optional feature (FC 6268). The 7311 Model D20 I/O drawer offers a modular growth path for
the OpenPower 720 system with increasing I/O requirements. When a OpenPower 720 is fully
configured with eight attached 7311 Model D20 drawers, the combined system supports up to
61 PCI-X adapters (in a full configuration, Remote I/O expansion cards are required) and
104 hot-swappable SCSI disks.
PCI-X and PCI cards are inserted from the top of the I/O drawer down into the slot. The
installed adapters are protected by plastic separators, designed to prevent grounding and
damage when adding or removing adapters.
The drawer has the following attributes:

Figure 1-3 on page 9 shows the different views of the 7311-D20 I/O drawer.
Note: 7311-D20 is the only supported I/O drawer for the OpenPower 720.
Note: The 7311 Model D20 I/O drawer initial order, or an existing 7311 Model D20 I/O
drawer that is migrated from another system, must have the RIO-2 ports available
(FC 6417).
