User Store Capacity Planning Checklist

Estimating the number of user directory requests that the Policy Server must make to service authentication and authorization requests requires specific information. Gather the following before beginning a user store capacity plan:

• The total number of daily authentications (authentication load) for the application.
• The total number of daily authorizations (authorization load) for the application.
• The sustained and peak periods during which users are authenticating to the application and requesting protected resources.

  Note: A capacity planning effort can help you identify metrics related to authentication load, authorization load, and sustained and peak levels of user activity.

• The total number of enabled policies. For each SiteMinder policy determine:
  • If the SiteMinder policy membership filter results in one or more user directory searches.
  • If the responses bound to the SiteMinder policy results in one or more user directory searches.
