Backup Exec 15 Client-Side Deduplication to EMC datadomain

I am trying to get client-side deduplication working on Backup Exec 15 and a datadomain unit.  I have the OST installed on the media server and client server.  I enabled the job to use the client side deduplication - however the deduplication ratio's show blank, no warnings on the job and the server can communicate with the datadomain appliance.  Do I need any additional licenses on our Backup Exec server (Copy Server Config, Managed Server, Enterprise Server or Storage Provisioning option?) I have the vray edition and deduplication option is enabled.
