IBM Flex System x440 Compute Node 20

I/O expansion options

The x440 has four I/O expansion connectors for attaching I/O adapter cards, as shown in Figure 6. There

is a fifth expansion connector (under I/O adapter 4) designed for future expansion options. The I/O

expansion connector is a very high-density 216-pin PCIe connector. Installing I/O adapter cards allows

the server to connect with switch modules in the IBM Flex System Enterprise Chassis. Each slot has a

PCI Express 3.0 x16 host interface and all slots support the same form-factor adapters.

Note: A second processor must be installed in order to use I/O adapter slots 3 and 4 in the x440 compute

node. This is because the PCIe lanes used to drive I/O slots 3 and 4 are routed to processors 2 and 4.

Figure 6 shows the location of the I/O expansion connectors.
