Configuring high availability
- To configure high availability, you use the MVS Console to associate two standalone BlackBerry MVS Server instances to form a high availability pair.
- You do not need to configure the active-standby status of the MVS Session Manager instances and the MVS BlackBerry Enterprise Server Connector instances because the components negotiate the status themselves.
- Two MVS Data Manager instances, two MVS Witness Server instances, and two MVS Event Manager instances are required per high availability pair to provide high availability.
- To support BlackBerry device-initiated calling for users, you must configure a DID/DDI number on the PBX for each MVS Session Manager.
- High availability eliminates a single point of failure for BlackBerry Mobile Voice System components, but the BlackBerry MVS cannot provide redundancy for the network between the computers where the BlackBerry MVS Server instances are installed. To provide redundancy for the network, you must provide redundancy for the communication path between the computers. To provide complete high availability for the entire BlackBerry MVS service, also consider redundancy for the data center locations, the PBX, the BlackBerry Configuration Database, and the BlackBerry Enterprise Server instances in the domain. For more information, contact your organization's IT administrator.
