Distribution Servers in a High Availability Environment Architecture

You can deploy additional Distribution Servers for high availability to prevent loss of audit events collected from the endpoints in an event of failure to the Distribution Server.

The following diagram shows an implementation of primary and secondary Distribution Servers in a high availability environment:

As illustrated in the previous diagram, a high availability implementation of the Distribution Server is based on the following:

• A primary Distribution Server and at least one secondary Distribution Server.
• A shared storage that holds the Message Queue data files and that is accessible by both the primary and secondary Distribution Servers.

  You place the Message Queue data files on the shared storage to verify that audit events messages that arrived form the endpoints are not lost if the Distribution Server fails.

• A shared host name.
• CA ControlMinder endpoints able to work with both the primary and secondary Distribution Servers.
