connection is labeled as x1, x2, x8, x12, x16, or x32, where the number is effectively the
number of lanes.
The PCIe interfaces supported on this server are PCIe Gen3, capable of 16 GBps simplex
(32 GBps duplex) on a single x16 interface. PCIe Gen3 slots also support previous generation
(Gen2 and Gen1) adapters, which operate at lower speeds, according to the following rules:
Place x1, x4, x8, and x16 speed adapters in the same connector size slots first, before
mixing adapter speed with connector slot size.
Adapters with smaller speeds are allowed in larger sized PCIe connectors, but larger
speed adapters are not compatible in smaller connector sizes (that is, a x16 adapter
cannot go in an x8 PCIe slot connector).
IBM POWER8 processor-based servers can support two different form factors of PCIe
adapters:
PCIe low profile (LP) cards, which are not used with the Power E850C server.
PCIe full height cards, which are used in the Power E850C server and the PCIe Gen3 I/O
expansion drawer (#EMX0).
Low-profile PCIe adapters are supported only in low-profile PCIe slots, and full-height cards
are supported only in full-height slots.
Before adding or rearranging adapters, use the System Planning Tool to validate the new
adapter configuration. For more information, see the IBM 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 update prerequisites to
install. To do so, use the IBM Prerequisite website:
https://www-912.ibm.com/e_dir/eServerPreReq.nsf
The following sections describe the supported adapters and provide tables of orderable
feature numbers. The tables indicate operating system support (AIX and Linux) for each of
the adapters.
Note: PCIe full height and full high cards are used in the Power E850C server and any
attached PCIe Gen3 I/O expansion drawer (#EMX0).
2.9.2 LAN adapters
To connect the Power E850C server to a local area network (LAN), you can use the LAN
adapters that are supported in the PCIe slots of the system. Table 2-16 lists the available LAN
adapters. Information about Fibre Channel over Ethernet (FCoE) adapters can be found in
Table 2-20 on page 52.
