Cluster

The ESET Cluster is a P2P communication infrastructure of the ESET line of products for Microsoft Windows Server.

This infrastructure enables ESET server products to communicate with each other and exchange data such as configuration and notifications, and can Synchronize greylisting databases as well as synchronize data necessary for correct operation of a group of product instances. An example of such group is a group of nodes in a Windows Failover Cluster or Network Load Balancing (NLB) Cluster with ESET products installed where there is a need to have the same configuration of the product across the whole cluster. ESET Cluster ensures this consistency between instances.

User interface settings are not synchronized between ESET Cluster nodes.

The ESET Cluster status page is accessible from the main menu in Tools > Cluster when properly configured, the status page should look like this:

To set up the ESET Cluster click Cluster wizard... For details on how to set the ESET Cluster up using the wizard click here.

When setting up the ESET Cluster, there two ways to add nodes - automatically using existing Windows Failover Cluster / NLB Cluster or manually by browsing for computers that are in a Workgroup or in a Domain.

Autodetect - Automatically detects nodes that are already members of a Windows Failover Cluster / NLB Cluster and adds them to the ESET Cluster.

Browse - You can add nodes manually by typing in the server names (either members of the same Workgroup or members of the same Domain).

note_icon_note NOTE

Servers don't have to be members of a Windows Failover Cluster / NLB Cluster to use the ESET Cluster feature. A Windows Failover Cluster or NLB Cluster is not required in your environment for you to use ESET Clusters.

Once you have added nodes to your ESET Cluster, the next step is the installation of ESET Mail Security on each node. This is done automatically during ESET Cluster setup.

Credentials that are required for remote installation of ESET Mail Security on other cluster nodes:

Domain scenario - domain administrator credentials

Workgroup scenario - you need to make sure that all nodes use the same local administrator account credentials

In an ESET Cluster, you can also use a combination of nodes added automatically as members of an existing Windows Failover Cluster / NLB Cluster and nodes added manually (provided they are in the same Domain).

note_icon_note NOTE

It is not possible to combine domain nodes with workgroup nodes.

Another requirement for the use of an ESET Cluster is that File and Printer Sharing must be enabled in Windows Firewall before pushing ESET Mail Security solutions to ESET Cluster nodes.

ESET Clusters can be dismantled by clicking Destroy cluster. Each node will write a record in their event log about the ESET Cluster being destroyed. After that, all ESET firewall rules are removed from the Windows Firewall. Former nodes will be reverted to their previous state and can be used again in another ESET Cluster if necessary.

note_icon_note NOTE

The creation of ESET Clusters between ESET Mail Security and ESET File Security for Linux is not supported.

Adding new nodes to an existing ESET Cluster can be done anytime by running the Cluster wizard as described above and here.
