| Research Abstract |
The purpose of this work was to develop a distributed storage management system that allowed central management of contents of storage devices, such as HDDs, of client machines while the client machines could fully utilize their hardware resources. We exploited our original hypervisor called BitVisor to allow maximum utilization of hardware functionalities from guest OSs with no extra overhead by allowing pass-through access to the hardware resources, while storage access was transparently transferred to remote servers by partially virtualizing storage devices with the hypervisor. Experimental results confirmed that our hypervisor could network-boot existing OSs such as Windows and Linux without any modification to the configuration of the OSs. The results also confirmed that the boot time was reduced by 14 seconds compared to that of local boot when the server cache was enabled.
