IBM Flex System PCIe Expansion Node 6
Supported PCIe adapter cards
The Expansion Node supports the following general adapter characteristics:
Full-height cards, 4.2 in (107 mm)
z
Low-profile cards, 2.5 in (64 mm)
z
Half-length cards, 6.6 in (168 mm)
z
Full-length cards, 12.3 in (312 mm)
z
Support for up to four low-profile PCIe cards
z
Support for up to two full-height PCIe cards
z
Support for up to one full-height double-wide PCIe card
z
Support for PCIe standards 1.1 and 2.0 (PCIe 3.0 adapters supported operating in PCIe 2.0)
z
The front-facing bezel of the Expansion Node is inset from the normal face of the compute nodes. This
inset is to allow for the use of cables connected to PCIe adapter cards that support external connectivity.
The Expansion Node provides up to 80 mm of space in the front of the PCIe adapter cards to allow for the
bend radius of these cables.
Table 4 lists the PCIe adapters that are supported in the Expansion Node. Some adapters must be
installed in one of the full-height slots as noted. If the NVIDIA Tesla M2090 is installed in the Expansion
Node, then an adapter cannot be installed in the other full-height slot. The low-profile slots and Flex
System I/O expansion slots can still be used, however.

Consult the IBM ServerProven® site for the current list of adapter cards that are supported in the
Expansion Node:

For information about the IBM High IOPS adapters, see the following IBM Redbooks® Product Guide:

Note: Although the design of Expansion Node allows for a much greater set of standard PCIe adapter
cards, the preceding table lists the adapters that are specifically supported. If the PCI Express adapter
that you require is not on the ServerProven web site, use the IBM ServerProven Opportunity Request for
Evaluation (SPORE) process to confirm compatibility in the desired configuration.
