Abstract
A method, of scheduling storage commands for processing on a virtual machine (VM) operating on a computing device includes (a) intercepting, by a front end storage scheduler module running on the VM, a set of storage commands each of which is directed at one of a plurality of virtual disks assigned to the VM, the plurality of virtual disks sharing underlying storage, (b) queueing the intercepted storage commands for each virtual disk into a respective front-end queue for each virtual disk, and (c) selectively dequeueing storage commands from the front-end queues onto their respective virtual disks in a manner that prioritizes certain virtual disks over others, wherein the selectively dequeueing is performed in a different order than the queueing. An apparatus, system, and computer program product for performing a similar method are also provided.
