A Satellite is a managed device that can perform some of the roles that a ZENworks Primary Server normally performs, including authentication, information collection, content distribution, and imaging. A Satellite can be any managed Windows or Linux device (server or workstation), but not a Primary Server. For more information, see ZENworks 11 Server Installation Guide and ZENworks 11 Discovery, Deployment, and Retirement Reference.
When you configure a Satellite, you specify which roles it performs (Authentication, Collection, Content, or Imaging). A Satellite can also perform roles that might be added by third-party products that are snap-ins to the ZENworks 11 framework.
You might, for example, create a Satellite in a location across a slow WAN link and create Closest Server rules to offload one or more roles from the Primary Server to the newly created Satellite to improve the performance of your ZENworks system.
