The Layout And Analyze For Storage System Of Non-linearity Network

As one of the core techniques of non-linear editing network for TV program production and broadcasting, Storage system not only decides the system size, but also decides the amount of program productions. At the same time, the storage system decides the security of user's material. On the other hand, to satisfy the enormous information of TV program, storage system has to own mass storage and wide bandwidth. If you want to use Non-linear network in the TV press production and broadcasting, the storage system must have high security. All we talked above makes a higher requirement to the storage system's design. So the design, the layout and the management of the storage system become very important in the design of non-linear editing network.In this paper, we analyze the storage system of the non-linear editing network in detail. According to the theoretical analysis and the practical test results, we discuss in the aspects of storage pattern, storage capability, storage bandwidth, the network structure of storage system, data compress format, system cost, expansibility, security and software etc, and we also analyses storage system of the non-linear editing network in different scales and different applications. Based on the theoretical analysis, we design the storage system which adapts to Xiamen TV station. That is it: in the aspect of storage pattern, we adopt SAN storage pattern, supplemented by NAS storage pattern. In the aspect of storage network structure, we adopt fiber channels, supplemented by Ethernet network. In the aspect of data compress format, we adopt both high code rate and low code rate compress format. In the aspect of the client of non-linear editing network, we adopt both workstations with video cards and workstations without video cards. Besides, in order to increase the bandwidth and security of the storage system, we adopt the virtualization storage system, the ZONING technology, the LUN technology, and so on.In this paper, we also calculated the capability and bandwidth of the storage system of Xiamen TV station's non-linear editing network. By the practical tests, we validate the theoretical analysis and calculate results.At the end of this paper, we discuss the way to settle some problems which were found in the use of the system. And we put forward the technical scheme of the future expand of the system, too. That is: Build the media asset management, and form the On-line, Near-line and Off-line storage system to re-use TV programs effectively. Furthermore, conformity different media network resources to share completely.
