Virtually separate data and management network

In this topology, the data network and management network are virtually separate. Packets from the data network and packets from the management network are sent over the same physical connection. VLAN tagging is used on all management-network data packets to keep the traffic between the two networks separated.

Note: If Lenovo XClarity Administrator is installed on a host running on a managed server in a chassis, you cannot use XClarity Administrator to apply firmware updates to that entire chassis at one time. When firmware updates are applied, the host system must be restarted.
When you install XClarity Administrator, define network settings using the following considerations:

Figure 1 shows an example implementation of virtually separate management and data networks in which the operating-system deployment network is configured as part of the data network. In this example, XClarity Administrator is installed on a managed server in a chassis.

Figure 2 shows an example implementation of virtually separate management and data networks in which the operating-system deployment network is configured as part of the management network, and XClarity Administrator is installed on a managed server in a chassis. In this implementation, XClarity Administrator does not need connectivity to the data network.
Note: If the operating-system deployment network does not have access to the data network, configure an additional interface on the servers to provide connectivity from the host operating system on the server to the data network, if needed.
