Management-only network topology (CentOS, ESXi, Hyper-V, KVM, or XenServer)

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. For information about firmware requirements, see Supported firmware.

Attention: If you intend to manage CMMs that are running a firmware level of Flex stack release 2PET12K through 2PET12Q, that have been running more than three weeks, and that are in a dual-CMM configuration, you must virtually reseat the CMMs before updating firmware using XClarity Administrator.
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, depending on the rack servers and components in the chassis that you might have. 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.
Figure 1. Sample Network topology - Management-only network
Illustrates a managament-only in an ESXi, Hyper-V, KVM, or XenServer environment.

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.
