Backup Exec 2014 and EMC DD160 DeDupe Option.....can't see storage

Running Backup Exec 2014 and plan on backing up our Exchange Server to a EMC DD160 before backing it up to tape.  Within BE we can't see the DD160 in order to configure storage.

Tech Support said I would need the Dedupe option license before I would be able to see the DD160 device (or before it appeared as available storage)

Is this true?

New to the BE world so just checking.  Hopefully a license purchase will solve this issue
