Simply so, how does SQL clustering work?

A Microsoft SQL Server Cluster is nothing more than a collection of two or more physical servers with identical access to shared storage that provides the disk resources required to store the database files. These servers are referred to as "nodes".

Likewise, why do we use clusters in SQL Server? Clustering is designed to improve the availability of the physical server hardware, operating system, and SQL Server instances but excluding the shared storage.

Just so, does SQL standard support clustering?

SQL Standard Edition SQL Server Standard Edition will provide most functionality that administrators will want. This includes the most common type of mirroring, and clustering up to two cluster nodes.

What SQL services are cluster aware?

Database engine and SSAS are cluster aware and can be installed as a part of cluster services and applications directly.
