Tutorial: Configure profile containers with Cloud Cache


Cloud Cache uses CCDLocations instead of VHDLocations. Don't use both settings.

Cloud Cache is an optional type of configuration to profile or ODFC containers. The primary function of Cloud Cache is to mitigate short-term or intermittent connectivity problems with the remote storage providers. Before following this tutorial, be sure to review the Cloud Cache overview along with the various configuration settings.

This tutorial depicts a Cloud Cache configuration for a profile container only. Cloud Cache with an ODFC container is supported and is configured similarly as in the ODFC tutorial, but replace VHDLocations with CCDLocations.

Learn how to

  • Enable the product for profiles
  • Specify the Cloud Cache locations for the containers
  • Verify the container has been attached and working

    2 Recommended to ensure user's don't use local profiles and lose data unexpectedly.
    3 Provides and easier way to browse the container directories.
    4 Prevents users from creating a local cache if at least 1 provider isn't healthy.
