Abstract
An aspect of performing input/output (IO) flow control in a storage system includes receiving an IO latency factor for each IO of a plurality of IOs in a workload. The IO latency factor specifies a priority level. An aspect also includes receiving a component latency factor, with respect to each of the IOs in the workload, for each component of a plurality of components in the storage system. The component latency factor indicates a degree to which the component is considered in assessing the workload. An aspect also includes applying, during processing of the workload, the IO latency factor and the component latency factor to each of the corresponding IOs; and determining an effective average latency of the plurality of IOs in the workload as a function of the applied IO latency factors and the applied component latency factors.
