Media Server Deduplication Pool only.

Select the media server that connects to the storage. The media server runs the core NetBackup Deduplication Engine components and functions as the storage server.

All media servers in your environment are in the drop-down list.

Also enter the credentials for the NetBackup Deduplication Engine. The deduplication components use the credentials when they communicate with the NetBackup Deduplication Engine. The credentials are for the engine, not for the host on which it runs.
