PROBLEM TO BE SOLVED: To provide an apparatus and method for assigning a weight to host quality-of-service indicators.SOLUTION: Quality-of-service indicators are provided from a host via a host interface. The quality-of-service indicators relate to data stored in a non-volatile data storage via the host. Workload indicators related to the quality-of-service indicators are measured, and a weight is assigned to the host in response to a correlation between the quality-of-service indicators and the measured workload indicators. The weight is applied to the quality-of-service indicators when responding to data access requests from the host.
