Abstract: Methods and systems for reallocating requests in a virtual volume storage provider to leverage underutilized resources are provided. An active node in an active-standby node pair configuration receives a request from a virtual machine monitor. The active node classifies the incoming request according to an allocation policy. If the request satisfies the allocation policy, the active node redirects the request to the standby node for execution. The request response is returned from the standby node to the active node. The active node redirects the response to the virtual machine monitor.

Abstract: A VASA provider is configured to include a control channel that is able to provide differentiated service to control path operations. The VASA provider maps a first set of data path service level objectives (SLOs) available on a storage system to a second set of control path SLOs. The VASA provider maintains a set of control path operation queues, such that a separate control path operation queue is maintained for each of the control path SLOs. Virtual machines are assigned control path SLOs based on their data path SLOs. Control path operations from virtual machines are mapped using the control path SLOs to the control path operation queues. The VASA provider processes control operations from the set of control path operation queues in a differentiated manner, to thereby provide different quality of service levels to the control operations of the different virtual machines.
