A hybrid storage access framework for virtual machines

In recent years, virtualization technology enables multiple virtual machines to run on a physical machine, where each virtual machine can run independently and own its operating system. Virtualization technology has been adopted in many IT industries because of its ability to improve hardware resource utilization, achieve low-power consumption, simplify server management, and reduce maintenance cost. However, since the hardware limitation of storage devices, I/O capacity could cause performance bottleneck. In the paper, we will propose a hybrid storage access framework for virtualization environment to dynamically adjust and enhance I/O performance by using solid-state drives (SSDs).
