Both vCenter Server and the virtual appliance require a database to store and organize server data and each vCenter Server instance must have its own database. vCenter Server 6.5 comes with a bundled PostgreSQL database that can be used if your environment has upto 20 hosts and 200 VM; for larger environments, you need an external supported database. vCenter Server 6.5 Windows-based supports Microsoft SQL Server and Oracle databases, while for the vCSA, Oracle is the only possible option.
