The PowerPivot Configuration Tool uses default values for an initial configuration. The server farm account is used to provision all of the services in the farm. This account must be a domain user account. On a new farm, the database server is used to create and run all of the databases used in the farm. If a local SQL Server database engine instance is detected, the configuration tool uses that instance as a default database server. You can use any SQL Server database engine that is supported for the SharePoint server farm. The Passphrase will be used to add or remove servers from the farm so be sure to type a phrase you will remember.  The port assignment for accessing Central Administration can be randomly generated or a specific port number. Leave the port field blank to use a generated port assignment. The PowerPivot Server is required for Excel Services to enable the core PowerPivot capabilities.
