The SQL database is essential for optimal operations. If the SQL database is lost all roles become unavailable. You can distribute your SQL database through clustering to prevent data loss.
To configure your SQL database server for a clustered environment, you must move the database to your mirrored data partition so that the contents of the database are identical on the active server and the standby server.
For details, see Configuring SQL Server for the cluster.
For information on SQL Server permissions, see Assigning SQL permissions on remote SQL Servers.
