摘要
A virtual network storage system comprises at least two network storage devices which connect to same SAN, at least one network storage device includes a device management unit for maintaining the mapping relationship between the global volume and the local volume of each network storage device, and for redirecting the access which is to the global volume to the network storage device which the global volume management unit of the global volume is located; at least one network storage device includes a global volume management unit for executing the access operation to the global volume according to the mapping relationship between the global volume and the local volume. A network storage device and virtual method are applied to the virtual network storage system. With the increasing of the network device, the ability of processing the access to the global volume is increased, and then the performance bottleneck caused by virtually operating to the network storage system; meanwhile, the reliability of the virtual network storage system is enhanced by the redundancy between the device management unit and the global volume management unit.
