IBM Flex System X6 Compute Nodes Product Guide 18
I/O expansion options
The X6 compute node has four I/O expansion connectors for attaching I/O adapters, as shown in the
following figure. Installing I/O adapters allows the server to connect to switch modules in the IBM Flex
System Enterprise Chassis. The following figure shows the location of the four I/O expansion slots.
Note: Slots 3 and 4 support only a subset of the adapters that are supported in slots 1 and 2. Slots 3 and
4 do not support dual-ASIC adapters because of the PCIe lanes that are routed to slots 3 and 4. For
specifics, see the "Network adapters" section.
