BlackBerry Enterprise Server high availability in a small-scale environment

The following diagram shows how you can configure a BlackBerry® Enterprise Server for high availability in a small-scale environment. Each primary BlackBerry Enterprise Server instance requires its own standby BlackBerry Enterprise Server instance. You install the primary BlackBerry Enterprise Server and standby BlackBerry Enterprise Server on different computers. You can install all BlackBerry Enterprise Server components on both computers to minimize the number of computers that the BlackBerry Enterprise Server environment requires.

This diagram shows the BlackBerry Enterprise Server high availability in a small-scale environment.

Both BlackBerry Enterprise Server instances in the BlackBerry Enterprise Server pair include, by default, the BlackBerry Attachment Service, BlackBerry Dispatcher, BlackBerry MDS Connection Service, BlackBerry Messaging Agent, BlackBerry Policy Service, BlackBerry Router, and BlackBerry Synchronization Service. By default, if you choose to install the BlackBerry Collaboration Service with both instances, the BlackBerry Collaboration Service is included in the BlackBerry Enterprise Server pair.

To administer the BlackBerry Enterprise Server pair, you can install the BlackBerry Administration Service with both BlackBerry Enterprise Server instances and configure high availability for the BlackBerry Administration Service separately.

In a large-scale environment, you can add any number of BlackBerry Enterprise Server pairs that use the same BlackBerry Configuration Database.
