Abstract: In an embodiment of the present disclosure, a processor receives a request to create a volume, wherein a volume placement policy comprises a plurality of scheduler algorithms, each of the scheduler algorithms selecting one or more worker nodes from a plurality of worker nodes for volume storage, determines, based on output from the plurality of scheduler algorithms, the one or more worker nodes, wherein output of each of the plurality of scheduler algorithms is assigned a weight in determining the one or more worker nodes; and causes a node agent in each of the one or more worker nodes to create the volume.

Abstract: A distributed flexible scheduler that dynamically balances network and storage traffic across links is proposed. The scheduler takes into account the bandwidth requirements of workloads provisioned in a cluster and dynamically distributes the network traffic and the storage traffic accordingly. There are three schemes involved in the proposed distributed flexible scheduler. In a first approach of Equal Distribution, network and storage traffic is distributed evenly across the links. In a second approach of Storage Preferred distribution, the aggregate storage bandwidth requirements of workloads exceed the network bandwidth requirements. In a third approach of Network Preferred distribution, the aggregate network bandwidth requirements of workloads exceed the storage bandwidth requirements.
