Abstract:
Storage performance of a single virtual machine in a cloud computing environment may be affected by other machines using the same physical storage. At the same time, user requirements concerning quality of service continue to increase, which brings new challenges for virtualized environments. In this paper we present the results of our research concerning data storage QoS. We discuss the quality aspects of storage services and propose a method for ensuring storage QoS by using monitoring and performance prediction based on heuristics. We also propose several heuristic policies, which can be implemented in a data transfer scheduler. Finally, we discuss test results obtained in a virtualized environment.
