Management-only network topology (CentOS, Citrix, Docker, Red Hat KVM, Rocky, Ubuntu, VMware ESXi, or Windows Hyper-V)

In this topology, Lenovo XClarity Administrator has only the management network. It does not have the data network.

Before you begin

Ensure that all appropriate ports are enabled, including:
  • Ports that XClarity Administrator requires (see Port availability)
  • External ports to the network
  • Internal ports to the CMM

Ensure that the minimum required firmware is installed on each device that you intend to manage using XClarity Administrator. You can find minimum required firmware levels from the XClarity Administrator Support – Compatibility webpage by clicking the Compatibility tab and then clicking the link for the appropriate device types..

Important
Configure the devices and components in ways that minimize IP address changes. Consider using static IP addresses instead of Dynamic Host Configuration Protocol (DHCP). If DHCP is used, ensure that IP address changes are minimized.

About this task

The following figure illustrates one way to set up your environment if Lenovo XClarity Administrator has only the management network (and not the data network). The numbers in the figure correspond to the numbered steps in the following sections.

Note
This figure does not depict all cabling options that might be required for your environment. Instead, this figure shows only the cabling-option requirements for the Flex switches, CMMs, and rack servers as they relate to setting up a management-only network.

If you intend to install XClarity Administrator to manage existing chassis and rack servers that have already been configured, proceed to Step 5: Install and configure the host.
