Choosing the location for CASO device and media data

During the installation of the Managed Media Server feature, you are prompted to keep the managed media server's device and media data either on the central administration server or in a database on the managed media server.

The following table compares how CASO tasks are performed depending on the location of the managed media server's device and media data:
