BladeCenter networking guidelines | IBM 8677 specification

Note: When failover occurs on a blade server, the secondary Ethernet controller takes over network communication, using the I/O module associated with that controller.

vInstall a pair of Ethernet switch modules in I/O-module bays 1 and 2.

Note: You can install a pass-thru module that is connected to an external Ethernet switch in either or both of these I/O-module bays.

vConfigure the Ethernet switch modules and your network infrastructure so that they can direct traffic to the same destinations.

Configuring the Ethernet controllers in the blade servers

Note: The BladeCenter unit does not include an Ethernet switch module; this is an optional feature that must be purchased separately. An Ethernet switch module or a pass-thru module that connects to an external Ethernet switch must be installed in the BladeCenter unit in I/O-module bay 1 or 2, or both, before the Ethernet controllers integrated on each blade server system board can be used.

The Ethernet controllers are integrated on each blade server system board. The Ethernet controllers provide 1000-Mbps full-duplex capability only, which enables simultaneous transmission and reception of data to the external ports on the Ethernet switches. You do not need to set any jumpers or configure the controller for the blade server operating system. However, you must install a device driver in the blade server to enable the blade server operating system to address the Ethernet controller. For blade server device drivers and information about configuring the Ethernet controllers, see the Broadcom NetXtreme Ethernet Software CD that comes with the BladeCenter unit.

BladeCenter networking guidelines

Your networking administrator should assist in the configuration of the network infrastructure prior to connecting the BladeCenter unit to the LAN switch or similar network device. This section provides additional guidelines that might be useful in setting up your system.

A BladeCenter chassis with two Ethernet switch modules and one management module has the following internal configuration:
