Configuring volume Quality of Service (QoS)

Another feature provided by Cinder is the ability to define and manage classes of service for volumes. Like volume encryption, Quality of Service (QoS) in Cinder is configured by volume type. By default, you can define values for minimum, maximum, and burst IOPS.
