Efficient and flexible storage visualization system based on distributed hash tables

초록

In these days, storage virtualization is becoming increasingly feasible and necessary. Most of the current storage virtualization systems are built on a Storage Area Network (SAN) or Network Attached Storage (NAS) and require additional software/hardware such as file servers and fiber channel switches, etc. In this paper, we address a novel storage virtualization system which allows users to view hard disk resources constituted of numerous nodes as a single logical storage space using distributed hash tables of P2P networking technologies. We extend our previous work on storage virtualization system, and more intensive experimental results and analysis are presented. The proposed system is developed at the device level of an operating system (e.g. MSWindows) and is suitable for users in Intranet environments. This system is developed to be recognized as a single hard disk in the Windows Explorer for the users' conveniences and does not require any hardware or supplementary client program. In addition, it enhances security via cutting off breaches from external networks. ©2013 International Information Institute.
