Prepare two computers to work as active and passive nodes for a Kaspersky Security Center failover cluster.

To prepare nodes for a Kaspersky Security Center failover cluster:

  1. Make sure that you have two computers that meet the hardware and software requirements. These computers will act as the active and passive nodes of the failover cluster.
  2. Make sure that the file server and both nodes are included in the same domain.
  3. Do one of the following:
    • On each of the nodes, configure a secondary network adapter.

      A secondary network adapter can be physical or virtual. If you want to use a physical network adapter, connect and configure it with standard operating system tools. If you want to use a virtual network adapter, create it by using third-party software.

      Ensure that the following conditions are met:

      • The secondary network adapters are disabled.

        You can create the secondary network adapters in the disabled state or disable them after creation.

      • The secondary network adapters on both nodes have the same IP address.
    • Use a third-party load balancer. For example, you can use an nginx server. In this case, do the following:
      1. Provide a dedicated Linux-based computer with nginx installed.
      2. Configure load balancing. Set the active node as the main server and the passive node as the backup server.
      3. On the nginx server, open all of the Administration Server ports: TCP 13000, UDP 13000, TCP 13291, TCP 13299, and TCP 17000.
  4. Restart both nodes and the file server.
  5. Map the two shared folders, that you created during the file server preparation step, to each of the nodes. You must map the shared folders as network drives. When mapping the folders, you can select any vacant drive letters. To access the shared folders, use the credentials of the user account that you created during step 1 of the scenario.

The nodes are prepared. To deploy the Kaspersky Security Center failover cluster, follow the further instructions of the scenario.
