Yes, the tier purchased is for maximums - you don't need all of them.

Interesting though.  Did this 'largest volume' portion of the license change 
after 7.1.x?  We were told by Sun, STK, and EMC at the time (circa 2004) that 
it was total disk in use, so we needed the Tier 5 license (greater than 50 TB 
aka unlimited use).

Not sure if I'd be mad or not if this was wrong, since we do have individual 
volumes larger than 10 TB anyway (VxFS of course - remember, this was pre-ZFS). 
 Now we basically have full power to add as much disk as we please, within 
server and device license restrictions.  

It's even more curious that Sun EBS VTL licensing for 10 TB is nearly 50% more 
than a comparable DBO option ($10K vs $7.5K List).  Even more reason why those 
of us deeply in adv_file are not likely to upgrade anytime soon; I'd rather 
wait for Avamar to finish integrating into the Networker code base.
