You can install the BlackBerry® Collaboration Service on a computer that is separate from the computer that hosts the BlackBerry® Enterprise Server. You can install the BlackBerry Collaboration Service on a remote computer to support multiple BlackBerry Enterprise Server instances, configure high availability for the BlackBerry Enterprise Server but exclude the BlackBerry Collaboration Service, or create a BlackBerry Collaboration Service pool that can support multiple BlackBerry Enterprise Server instances. For more information about configuring the BlackBerry Collaboration Service high availability, see the BlackBerry Enterprise Server Planning Guide.

The BlackBerry Collaboration Service uses a persistent socket connection for each instant messaging session. You can install the BlackBerry Collaboration Service on a remote computer to maximize the number of available sockets.

You can install only one type of BlackBerry Collaboration Service (for example, IBM® Lotus® Sametime®). Users can use only one type of collaboration client on their BlackBerry devices.
