Research And Development Of SAN-based Storage Management Software

The expansion of IT applications has resulted in more and more data being produced, making it necessary to manage high-capacity storage systems. If the storage is connected in a disorderly fashion to different types of server, free space is wasted and it becomes difficult to manage. Furthermore, increases in the volume of data make it harder to back up. One idea that has been put forward to solve these problems is the Storage Area Network (SAN), which is defined as a network where storage devices and server devices are connected together by fast links such as optical fiber channels. SAN can be used to implement integrated management of storage resource, to reduce the management costs, to improve the speed of data access and the efficiency of storage space, and to increase system flexibility and expandability. The sharing of data and storage resource between different types of server also becomes possible.
