Allows for linear, predictable performance gains as systems scale. True Quality of Service (QoS) requires that storage systems are always aware of the total available performance. As systems scale, they must be capable of increasing both capacity and performance independently and in a predictably linear pattern.

Guaranteed quality of service isn't a feature. It requires an architecture design for it from the start. The second requirement for guaranteed quality of service is a true scale-out architecture. Let me show you why. Most storage systems today, including many solid-state storage systems, are designed with a controller and disk shelf architecture.
