Automated QoS function is a function wherein, by a user configuring target value (Target Response Time in millisecond) for every volume according to the priority of tasks, the bandwidth is automatically adjusted to satisfy target value and automatic tuning of performance is performed. The target value can be configured with each volume. The volumes to which target value can be configured are Flexible Tier Volumes (FTVs). There is no upper limit to the number of FTVs to which target value can be configured.
Furthermore, all operations of Automated QoS function such as control of activation and stop, or configuration and changing of target value are performed with the Web Console or Command Line Interface.
