IBM Flex System x440 Compute Node 23

Network adapters

As described in "Embedded 10Gb Virtual Fabric," certain models (those with a model number of the form

x4x) have two 10 Gb Ethernet controllers on the system board, and its ports are routed to the midplane

and switches installed in the chassis through two Compute Note Fabric Connectors that takes the place of

adapters in I/O slots 1 and 3.

Models without the Embedded 10Gb Virtual Fabric controller (those with a model number of the form x2x)

do not include any other Ethernet connections to the Enterprise Chassis midplane as standard. Therefore,

for those models, an I/O adapter must be installed to provide network connectivity between the server and

the chassis midplane and ultimately to the network switches.

The following table lists the supported network adapters and upgrades. Adapters can be installed in any

slot. However, compatible switches must be installed in the corresponding bays of the chassis.

* For x4x models with two Embedded 10Gb Virtual Fabric controllers standard, the Compute Node Fabric

Connectors occupy the same space as the I/O adapters in I/O slots 1 and 3, so you have to remove the Fabric

Connectors if you plan to install adapters in those I/O slots. To use slots 3 and 4 requires the second processor.
