Where is the vCenter Server database configured?

The vCenter Server database is configured during the vCenter Server installation. This process involves selecting the type of database to be used, which can be either an embedded database or an external database, as well as providing the necessary connection information such as hostnames, usernames, and passwords. This initial setup is critical because the database is essential for storing configuration data, performance metrics, and events related to all managed virtual machines and hosts within the vSphere environment.

Establishing the database during the installation ensures that vCenter Server has the necessary data storage foundation ready from the outset, allowing it to manage and orchestrate various workloads efficiently. Configuration after the installation typically focuses on tuning and maintenance rather than initial setup. Meanwhile, configurations during ESXi installation or at host addition stages are directed toward host settings and networking rather than vCenter's database management.
