70 IBM Power 770 and 780 (9117-MMD, 9179-MHD) Technical Overview and Introduction
2.8.3 IBM i IOP adapters
IBM i IOP adapters are not supported with the Power 770 and Power 780, which has the
following results:
Existing PCI adapters that require an IOP are affected.
Existing I/O devices are affected, such as certain tape libraries or optical drive libraries, or
any HVD SCSI device.
Twinaxial displays or printers cannot be attached except through an OEM protocol converter.
Before adding or rearranging adapters, use the System Planning Tool to validate the new
adapter configuration. See the System Planning Tool website:
http://www.ibm.com/systems/support/tools/systemplanningtool/
If you are installing a new feature, ensure that you have the software that is required to
support the new feature, and determine whether there are any existing PTF prerequisites to
install. See the IBM Prerequisite website for information:

2.8.4 PCIe adapter form factors
IBM POWER7 and POWER7+ processor-based servers are able to support two form factors
of PCIe adapters:
PCIe low-profile (LP) cards, which are used on the Power 710 and Power 730 PCIe slots.
Low profile adapters are also supported in the PCIe riser card slots of the Power 720 and
Power 740 servers.
PCIe full-height and full-high cards, which are plugged into the following servers slots:
– Power 720 and Power 740 (Within the base system, five PCIe half-length slots
are supported.)
–Power750
–Power755
–Power760
–Power770
–Power780
–Power795
– PCIe slots of external drawers, as FC 5802 and FC 5877
Low-profile PCIe adapter cards are supported only in low-profile PCIe slots, and full-height
and full-high cards are supported only in full-high slots.
Figure 2-17 on page 71 lists the PCIe adapter form factors.
