I am planning to install two SQL Server 2008 instances on an active/passive cluster. Each instance is supporting the same application, but the DBs will be supporting specific geographic locations. I'd like to name the instances to reflect the name of the application and the site, factoring in that at least one instance will be a named instance.
My understanding is that the SQL Server Virtual Name has to be registered in AD and can only be used once. If this is true, I can not have instances on this cluster named \EAST and \WEST as the can't be registered in AD more than one, or can I?
Can I have two named instances on a cluster with the same base instance name or will the base instance name have to be unique for AD registration purposes?
