Can a cluster have more than one SQL Server instance?

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. All, or all but one, of the SQL Server instances on a SQL Server will be named instances.

What are services that share the same version of SQL Server?

Is it safe to install multiple instances of SQL Server?

Security challenges – sometimes, we get those awful folks who insist on being able to RDP into the Windows instance that hosts their databases. If they insist on being sysadmin on the box altogether, then they can make changes that wreak havoc on the other running instances.
