6.3 Management network
In an IBM Flex System Enterprise Chassis, you can configure separate
management and data networks.
The management network is a private and secure Gigabit Ethernet network used
to complete management-related functions throughout the chassis, including
management tasks related to the compute nodes, switches, and the
chassis itself.
The management network is shown in Figure 6-36 (it is the blue line). It connects
the CMM to the compute nodes, the switches in the I/O bays, and the FSM. The
FSM connection to the management network is through a special Broadcom
5718-based management network adapter (Eth0). The management networks in
multiple chassis can be connected together through the external ports of the
CMMs in each chassis via a GbE Top-of-Rack switch.
