A storage system has a QOS recommendation engine that monitors storage system operational parameters and generates recommended changes to host QOS metrics (throughput, bandwidth, and response time requirements) based on differences between the host QOS metrics and storage system operational parameters. The recommended host QOS metrics may be automatically implemented to adjust the host QOS metrics. By reducing host QOS metrics during times where the storage system is experiencing high volumes of workload, it is possible to throttle workload at the host computer rather than requiring the storage system to expend processing resources associated with queueing the workload prior to processing. This can enable the overall throughput of the storage system to increase. When the workload on the storage system is reduced, updated recommended host QOS metrics are provided to enable the host QOS metrics to increase. Historical analysis is also used to generate recommended host QOS metrics.
A non-transitory tangible computer readable storage medium having stored thereon a computer program for adjusting host QOS metrics based on storage system performance, the computer program including a set of instructions which, when executed by a computer, cause the computer to perform a method comprising the steps of:
