I'd be more worried about database I/O bandwidth. Expiration and deduplication are going to hammer the database. All the usual rules apply, such as avoiding RAID5, using your fastest disks, using striping, not overloading any one bus, controller, or drive. If you have any of these bottlenecks then adding more cores cannot improve performance. Poor database disk I/O can kill a TSM system, regardless of its CPU resources. If you've got the budget for it, think about using solid state storage for the TSM database in order to support multiple expiration and deduplication processes.
