Configure network ports on Windows Clustered Systems

Each node of a Windows Cluster should be configured exactly the same including the networking parameters (other than unique IP addresses for each system).

Configure IP Addresses

Every node on a Windows Cluster should be configured with

  • IP Addresses
  • DNS
  • Default Gateways
  • Interconnect Networks (for 2-node clusters only)

and any other relevant networking details.   The DNS IP address will likely be your Active Directory servers, otherwise you will have to guarantee the new servers have access to your Active Directory domain servers.

Each system will likely require the configuration of:

  1. Management Ports IP Addresses
  2. Data Access high-speed 10/25/50/100 GbE ports IP addresses
  3. DNS IP addresses configured on the network adapter on the network segment which provides the best access to Active Directory
  4. Default Gateway may be optionally configured on the best network segment which has routable access to the Internet.   Without this access, the Microsoft Updates will have to be downloaded and installed out of band
  5. IPMI (Lights Out console) IP addresses. This is available on the shared NIC or on the dedicated IPMI port. The shared port can be used to reduce the number of network cables to your servers. The shared connection looks like two virtual ports connected to a single cable on one physical port. Different IP network subnets can be defined for the Management interface as well as the IPMI interface.

Rename the Network Adapters

The network adapters will have default names. It will be easier to manage your systems if you give each network interface a more descriptive name.

To rename a network interface:

  • Control Panel >> View network status and tasks >> Change adapter settings

change network adapter settings

In the example above, the network interface Ethernet 3 is renamed to Interconnect.   This port is the internal network running inside the chassis which is used for cluster traffic and is always available regardless of external connections.

Note: Your IT standards may vary and you should comply with your own standards.
