Creating pools of BlackBerry Enterprise Server components that are located in different data centers

You can create pools of BlackBerry® Attachment Service, BlackBerry Collaboration Service, BlackBerry MDS Connection Service, or BlackBerry Router instances that you installed in different data centers.

If your organization's environment includes Microsoft® Exchange, you must consider the potential latency that might occur when the BlackBerry® Enterprise Server connects to a messaging server that is located in a different data center.

If you create a BlackBerry Attachment Service pool for a BlackBerry Enterprise Server, you can configure a primary group of BlackBerry Attachment Service instances that are located in the same data center as the BlackBerry Enterprise Server, and a secondary group of BlackBerry Attachment Service instances that are located in a different data center. The BlackBerry Enterprise Server uses the local BlackBerry Attachment Service instances if they are running.

If you create a BlackBerry Collaboration Service pool or BlackBerry MDS Connection Service pool with automatic failover turned on, you installed some of the BlackBerry Collaboration Service and BlackBerry MDS Connection Service instances in different data centers, and the BlackBerry Collaboration Service instance or the BlackBerry MDS Connection Service instance with the active connection to the BlackBerry Enterprise Server stops responding, the BlackBerry Enterprise Server might not assign the active connection to another BlackBerry Collaboration Service or BlackBerry MDS Connection Service instance that is located in the same data center.
