Enabling and Disabling Power and Capacity Management with XenApp Connector for Configuration Manager 2007 R2

Oct 09, 2015
XenApp Connector for Configuration Manager 2007 R2 uses the XenApp Power and Capacity Management feature to manage the power states and load consolidation of XenApp servers when sending Configuration Manager advertisements and installing applications. This enables XenApp Connector to install applications on servers managed by Power and Capacity Management with minimal disruption to user sessions.
To allow Power and Capacity Management to manage power states and load consolidation of XenApp servers, XenApp Connector changes the servers' power controller preference and power control mode:
  • If no advertisements are pending for a XenApp server, the server's power controller preference remains at 1, the default ranking for servers managed by Power and Capacity Management.
  • When you designate an online XenApp server to receive an advertisement, XenApp Connector:
    • Changes the power controller preference to 5
    • Sets the server state is to Maintenance just before the application is installed
    • Changes the power controller preference changes to 1 and enables users to log in, after advertisement processing completes
  • When you designate an offline XenApp server to receive an advertisement, XenApp Connector:
    • Changes the power controller preference to 6
    • Sets the server state to Maintenance and the server control mode to Unmanaged for the duration of the maintenance window or the processing of all pending advertisements, whichever occurs first
    • Changes the power controller preference changes to 1, after advertisement processing completes or the maintenance window closes

    The XenApp power-on interval, which is set when XenApp Connector is configured, determines how long in advance of processing advertisements offline servers are powered on.

XenApp Connector uses Power and Capacity Management to manage the installation of installed applications only and does not affect the deployment of Microsoft Application Virtualization (App-V) sequences.

Citrix recommends you document your current XenApp Power and Capacity Management server configuration before modifying it for XenApp Connector.

To enable XenApp Connector to use Power and Capacity Management

To enable XenApp Connector to use Power and Capacity Management to manage XenApp server power states and load consolidation, from the Power and Capacity Management console, configure these settings for the XenApp server:
  • Set power control mode to Managed.
  • Set power control preference to 1.

To disable XenApp Connector from using Power and Capacity Management

To disable XenApp Connector from using Power and Capacity Management to manage XenApp server power states and load consolidation, from the Power and Capacity Management console, set the XenApp server's power controller preference to a value other than 1, 5, or 6.
