Guidelines
When setting your inband and out-of-band data carousel rates, consider the
following points as they pertain to the configuration for your BFS:
following points as they pertain to the configuration for your BFS:
Although some applications may require their own data carousel, you are not
required to configure a data carousel for each application. You may assign
multiple files to the same carousel as long as you consider the current and future
performance requirements of the DBDS network. The more files you assign to a
given carousel, the longer it will take for the files to transfer to the DHCT.

For applications that do not require their own data carousel, you can redistribute
existing application files among the data carousels as you add new application
files to your system. Consider the current and future transfer speed of files when
you are opting to redistribute application files.

Do not use system default data carousels for any third-party application files.
Cisco reserves default carousels for system files only.

Determine the data rate required for the third-party application from the third-
party application vendor. Defining the appropriate data rate enhances
performance of the data carousels. Refer to the Recommendations for Data Carousel
Rate Management Technical Bulletin (part number 716377) for additional assistance
in determining the data rate. Vendors for third-party applications will specify the
carousel quantity, name, and bandwidth requirements for the application.
