NLB configuration
In order to configure the Network Load Balancer, proceed with the following steps :
1. On one of the node machines, call Start > Administrative Tools > Network Load Balancer Manager.
Thereby, the service is activated on all node machines, which is necessary for cluster operation.
2. A tripartite configuration screen opens. To build a new cluster, go to Cluster > New in the menu or use the right-hand mouse key to call the context menu and select New Cluster.
NOTE: All members of the NLB cluster must be running on the same ESXi / ESX host.
3. In the New Cluster: Connect screen, in the Host field, enter the IP address of the first node machine.Click on Connect.
4. You are in the New Cluster: Host Parameters screen now. In the field Priority, a pre-defined value is displayed, which is a mere numeration and does not imply a prioritization. The IP address field contains the IP address of the network interface.
When all values are correct, click on Finish. The process of adding a node to the cluster may take 1-2 minutes.
5. In the screen New cluster: Cluster IP Addresses, the common addresses of the cluster are provided. Click on Add.
6. In the dialog window Add IP Address, in IPv4 address, enter the IP address at which the cluster shall be reachable. In the Subnet mask field, enter the corresponding subnet mask.
Under New Cluster: Cluster IP Addresses, the address of the cluster appears.Click Next.
The cluster shall be reachable via DNS name, enter it in Full Internet name, e. g. cluster.domain.com. In the field Cluster operation mode, select Unicast.
With this setting, all network interfaces in the outer network will be assigned the same MAC address. Thus, inbound data packets are initially received by all node machines and then filtered by the network load balancer.
