Right let's be straight are we talking mirroring or clustering here?

My response :- All objects

That is not a great response to be fair. At what level are we talking?
You could say that SQL Server depends on Windows, but thats stating the obvious.
Are you referring to a clustered or non clustered instance of SQL Server?


saidapurs (10/11/2012)
2. What are SQL Cluster dependence ?
My Response :- Cluster admin, storage, etc

A clustered instance of SQL Server typically has the following resources


  • Virtual IP address

  • Virtual Network name

  • clustered disk resources

  • SQL Server instance service

  • SQL Server instance agent service



The virtual name is dependant upon the virtual IP
The SQL Server service is dependant upon the disk and network name resources
The SQL Server agent is dependant upon the SQL Server service

Draw this out diagrammatically and you'll have yourself a small tree ;-)

Essentially, a mirror instance of SQL Server has the same dependencies as a non clustered instance (ignoring the mirrorred partner part of the equation)

Dependencies for a non clustered instance of SQL Server are pretty much taken care of by the OS.

  • a valid computername

  • a valid IP address

  • disk(s) where the sql server binaries and data files are stored



At the service level in Windows the SQL Server agent depends upon the SQL Server service.

Now start throwing in AlwaysOn groups or AO groups and FCIs then you have a real headache for dependencies ;-)
