A High Usage configuration extends the High Availability configuration by adding servers to the cluster. This allows Teradata Viewpoint to scale to thousands of concurrent users.
The additional Teradata Viewpoint servers run only the Teradata Viewpoint portal and not the DCS or cache database. Instead, they point to the cluster-wide cache database to access users, permissions, preferences, and collected data.
The two additional Teradata Viewpoint servers are optional and are not required for high availability. Even though these additional servers run only the Teradata Viewpoint portal, they are staged the same as any Teradata Viewpoint server and have the DCS and cache database installed, but not enabled.
