How many instances can a SQL Server have?
You can install as many as 50 SQL Server instances on a Windows Server; obviously, we do not recommend this. In a Windows failover cluster, the maximum number of SQL Server instances is reduced by half if you're using shared cluster drives. Only one of the SQL Server instances on a server can be the default instance.
Can a SQL Server have multiple instances?
Yes, we can use multiple instance of SQL Server of same machine/server. All instances of the database engine other than the default instance are identified by an instance name specified during installation of the instance.
How do I create multiple instances of SQL Server?
