Spreading quality of service values over a given range with minimal deviation

摘要

Embodiments for performance management in a computing storage environment. In a storage system having a predetermined number of available quality of service (QoS) values associated with a performance of the storage system, the predetermined number of available QoS values are spread over a range such that a user requested QoS value is matched with one of the available QoS values within an optimal deviation value to a given precision.
