Description
You can create a mirror member called an async member, which can be configured to receive updates from one or more mirrors across the enterprise. This allows a single node to act as a comprehensive enterprise-wide data warehouse. Async members do not belong to a mirror and, therefore, are not candidates for failover.
For more information, see the Async Mirror Members section of the “Mirroring” chapter in High Availability Guide
