Requirements for client-side dedup

If I have a file server with 10TB of file data and the Backup Exec Windows Agent 2014 installed & a backup server with Backup Exec 2014 and Deduplication Option 2014 & I'm going to use CLIENT-SIDE deduplication, what hardware is required and/or recommended for the backup server? I can calculate what I will need for the media storage, but what about the deduplication volume?

Thanks again,
