US Patent 9521089 Multi-layer QoS management in a distributed computing environment

A system for multi-layer quality of service (QoS) management in a distributed computing environment includes: a management node hosting a workload scheduler operable to receive a workload and identify a workload QoS class for the workload; and a plurality of distributed compute nodes, the workload scheduler operable to schedule running of the workload on the compute nodes. The workload scheduler is operable to: translate the workload QoS class to a storage level QoS class; communicate the storage level QoS class to a workload execution manager of the compute nodes; and communicate the storage level QoS class to one or more storage managers, the storage managers managing storage resources. The storage managers are operable to extend the storage level QoS class to the storage resources to support the workload QoS class.
