Capacity derived storage QoS limits
AWS EBS provides a deterministic number of IOPS based on the capacity of the provisioned volume with Provisioned IOPS. Similarly, the newly announced throughput optimized volumes provide deterministic throughput based on the capacity of the provisioned volume. Cinder should, in addition to current per volume maximums, be able to set lower qos limits based on the provisioned capacity.

Whiteboard
Not sure if most backends have a concept of performance related to capacity. Perhaps you can explain more what you are thinking about for this. This may need a spec written so it have be reviewed and discussed.
