Does SQL Server support clustering?
SQL Server clustering is the term used to describe a collection of two or more physical servers (nodes), connected via a LAN, each of which host a SQL server instance and have the same access to shared storage. If you are on a standalone server, a hardware failure can bring your operations to a halt.
