I/O Drawers And Usable Pci Slots - IBM Power 720 Overview

Figure 1-5 shows the front view of the PCI-X DDR 12X Expansion Drawer.
Figure 1-5 PCI-X DDR 12X Expansion Drawer (FC 5796) and 7314-G30 front view
The I/O drawer has the following attributes:
One or two FC 5796 drawers are held by the 4 EIA unit rack-mount enclosure (FC 7314).
Six PCI-X DDR slots, 64-bit, 3.3 V, 266 MHz that use blind swap cassettes.
Redundant hot-swappable power and cooling units.
The 7314-G30 drawer is equivalent to the FC 5796 I/O drawer described before. It provides
the same six PCI-X DDR slots per unit and has the same configuration rules and
considerations as the FC 5796 drawer.
Notes:
Mixing FC 5802 or FC 5877 and FC 5796 on the same loop is not supported. Mixing
FC 5796 and the 7314-G30 on the same loop is supported with a maximum of four
drawers total per loop.
IBM i does not support the 7314-G30 I/O drawer.

1.6.3 I/O drawers and usable PCI slots

The various I/O drawer model types can be intermixed on a single server within the
appropriate I/O loop. Depending on the system configuration, the maximum number of I/O
drawers supported can vary.
Table 1-14 summarizes the maximum number of supported I/O drawers and the total number
of available PCI slots when expansion consists of a single drawer type.
