When you install vCenter Server and the Platform Services Controller, the installer does a pre-install check, for example, to verify that enough space is available on the virtual machine or physical server where you are installing vCenter Server, and verifies that the external database, if any, can be successfully accessed.

When you deploy vCenter Server with an embedded Platform Services Controller, or an external Platform Services Controller, vCenter Single Sign-On is installed as part of the Platform Services Controller. At the time of installation, the installer provides you with the option to join an existing vCenter Single Sign-On server domain. When you provide the information about the other vCenter Single Sign-On service, the installer uses the administrator account to check the host name and password, to verify that the details of the vCenter Single Sign-On server you provided can be authenticated before proceeding with the installation process.

The pre-install checker performs checks for the following aspects of the environment:

Windows version

Minimum processor requirements

Minimum memory requirements

Minimum disk space requirements

Permissions on the selected install and data directory

Internal and external port availability

External database version

External database connectivity

Administrator privileges on the Windows machine

Any credentials that you enter
