Each scenario is assigned to a default scenario group called Scenarios. You can use this group for all scenarios you create, or you can add new groups to organize your scenarios according to your own criteria. Scenario groups are displayed on both the Manager and the Overview Page.
In distributed server environments, in which several servers (database server, application server, web front end server) comprise the environment, you must create individual scenarios to protect all the servers in the deployment. If an Is Alive check triggers a failover, only the affected server is failed over to its Replica. The resulting data split, where some operations are applied to original Master servers and other operations are applied to the Replica in the failed scenario, can introduce performance issues.
Scenario groups let you manage related scenarios, such as those protecting all servers in a distributed environment, as a single entity. For example, for end-to-end protection in a distributed server environment, you may have a SQL scenario to protect the database component, and several application-specific scenarios to protect application servers. A scenario group lets you set switchover properties at the group level, instead of at individual server levels.
For more information, see the topic, Enable Scenario Group Management, and the Operation Guide for the specific distributed server application.
Note: For SharePoint Server farms, scenario group creation is handled automatically. For other distributed server environments (BlackBerry Enterprise Server, Microsoft Dynamics CRM), you must manually create groups and scenarios.
