An effective QoS implementation helps tunes data storage to meet the specific needs of applications. New tools that offer more automation are emerging to help. Practically every storage array vendor claims its box has quality of service (QoS) built in. To a degree, all these vendors are correct. The trouble, however, is how each one defines quality of service. If you define QoS as the features built into your array then, based on that loose definition, you have QoS capability.

The one sentence that caught my eye in the Wikipedia entry was, "Quality of service is the ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow." This is probably the best description that can be applied to storage. The basic issue we've grappled with for decades is how to deliver the right storage performance to an application.
