Installing McAfee ePO in a cluster environment McAfee ePO provides high availability for server clusters with Microsoft Cluster Server (MSCS) software. Installing the software into your Microsoft Cluster Server environment requires additional steps. Cluster installation is supported on Windows Server 2008 R2, Windows Server 2012, Windows Server 2016, and Windows Server 2019. Successful installation depends on proper setup of the Microsoft Cluster Server software. For more information about MSCS setup, see the Microsoft documentation. Cluster installation terminology This terminology is used in the cluster installation instructions. Term Definition Data drives Required by Microsoft Cluster Server and McAfee ePO. For information about setting up data drives, see the Microsoft documentation. This is the location where you install the McAfee ePO files. ePO Virtual IP address resource The IP address resource that you create as part of the McAfee ePO cluster installation. This virtual IP address represents the McAfee ePO cluster installation as a whole. References to this IP address point to the currently active node in your cluster. ePO Virtual Network Name resource The Network Name resource that you create as part of the McAfee ePO cluster installation. This virtual Network Name represents the McAfee ePO cluster installation as a whole. References to this Network Name point to the currently active node in your cluster. Cluster installation prerequisites Before you begin your cluster installation, review this list of requirements and prerequisites, and make sure that each is in place or the information is available. These requirements apply to installations on Windows Server 2008 R2, Windows Server 2012, Windows Server 2016, and Windows Server 2019. McAfee ePO supports two-node cluster environments only. Environments with more than two nodes are not supported. Microsoft Cluster Server is set up and running on a cluster of two servers. Data drives present and available to all nodes in the cluster according to Microsoft guidelines. A supported remote SQL Server is configured. To confirm that McAfee ePO can communicate with this server during installation: Verify that the SQL Browser Service is running. Make sure that the TCP/IP Protocol is enabled in the SQL Server Configuration Manager. You might need to provide these details during the installation process (depending on your configuration), on the Database Information page: The name of your SQL Server. Depending on the configuration, format this name using the SQL Server name or the SQL Server name with instance name. The dynamic port number, if any, used by your SQL Server. Specify the dynamic port number during the installation process, on the Database Information page. Create the McAfee ePO application roleThe McAfee ePO application role is required to allow Microsoft Cluster Services to control McAfee ePO. Create the Client Access PointThe Client Access Point defines the McAfee ePO Virtual IP address and Virtual Network names so your cluster nodes can communicate with your McAfee ePO server. Add the data driveThe data drive is the location where you install McAfee ePO. Install McAfee ePO software on each cluster node Run the Cluster installation on each of the nodes. Create the Generic Service resourcesThe Generic Service resources enable the cluster server to control the McAfee ePO server, by starting and stopping the McAfee ePO services on the correct cluster. Test the McAfee ePO cluster installation When the McAfee ePO role is online and running in Failover Cluster Manager, use this task to make sure that the software functions in a failover situation.
