Peer Gateways

In installations that contain multiple Gateways, you can configure up to eight Gateways as peers in a group. You can control peers in the group from a local Gateway. The local Gateway is the Gateway on which you make changes to the configuration. In a deployment that uses Peer Gateways, any Gateway in the group can be used as the local Gateway.

Peer Gateways can:

• Provide redundancy in the event of a system failure
• Share the processing load to improve message throughput

From the local Gateway, you can manage peers in the following ways: Show me

• Create a security policy, and apply it to all Peer Gateways
• Monitor the status of Peer Gateways
• Run consolidated reports throughout the Peer Group.
• Manage held and queued messages for all Gateways, for example analyze, release and delete held messages
• Track messages across Peer Gateways
• Consolidate PMM messages for all Peer Gateways in the group. Users then receive a single PMM digest for messages held in PMM areas on all Gateways in the group
• Consolidate report information between peers. You can manage reports from any peer in the group, and create custom reports that include report data from the local peer only, all peers in the group, or any combination of peers in the group

When you peer an Exchange Gateway with an Gateway, you will see features in one that are only supported in the other. For example, the following shows an Exchange Gateway feature appearing in a peered Gateway. Show me

Unsupported features are highlighted in the Gateway user interface. Show me
