PowerPivot Server Components
SQL Server 2008 R2
This section describes the server components in Microsoft SQL Server PowerPivot for SharePoint that enable Analysis Services to run as a distributed server application on a SharePoint farm. A new SharePoint service architecture enables you to scale PowerPivot query processing across multiple application servers, and manage them all from within Central Administration.
The PowerPivot Service coordinates client requests for PowerPivot data. It also monitors and maintains status of the server instances in the farm, participates in usage data collection and data refresh, and allocates processing requests among the available servers. It is tightly coupled with the Analysis Services service instance that is always installed with it on the same application server. To use a PowerPivot service, you must have a service application. For more information, see PowerPivot Service Application.
