Research of the Router Scheme for Virtual Storage

With the development of storage technology, the increase of the storage quantity and diverse forms, virtual storage has become a most adaptable technology in the current environment. It helps users to provide interactive procedure in the heterogeneous environment, maintain the operating system continuity, simplify the storage management complexity and reduce the storage cost. Virtual storage is to centralized manage multiple storage devices and provide large capacity, high data transmission performance for users. It can be realized in three levels: virtual storage based on hosts, networks and storage devices. Virtual storage based on networks can be further divided into virtualization based on net devices, switches and routers. This paper focus on the router scheme in for virtual storage, which has higher performance and better security compared with other method. Virtualization based on routers is to integrate virtual modules into the routers, giving storage routers in the network have both exchange functions of the switches and protocol conversion functions of the routers. It makes full use of the current storage resources and protecting user investment, and also allows users in the Ethernet connect to the virtual storage pool, which can use different protocol channels at the same time. As the focus study at present, virtual storage can be used in several fields, such as data mirroring, data replication, tapes backup enhancement devices, real-time duplication, real-time data recovery and application integration.
