The Design And Realization Of The Storage SDN Controller Management Software

Since the 21 st Century, the Internet technology obtained explosive growth with the popularity of the Internet. Gradually traditional Ethernet architecture could not meet the management needs of the explosive growth in data traffic and complex network topologies. One more advanced and more flexible Internet architecture –Software Defined Network(SDN) came into being. The biggest feature of SDN is that decouples control from forwarding data plane. SDN is a promising architecture for high volume and virtualized complex networks.At the same time, Storage area network(SAN) with FC and FCoE has become the mainstream of storage networks. However, SAN is also facing problem which Ethernet faced: existing architecture can’t solve the problems are caused by outbreak data and more complicated network. So, SDN combined with SAN to generate storage software defined network(SSDN). SAN under SSDN architecture consists of four parts: SSDN controller, SSDN switches, storage devices and servers.This paper studies the SSDN Controller management software, designs and completes its basic function. SSDN is the “brain” of the SAN. In addition to forward data frames, all control frames in the SAN are handled to the controller. So management software of SAN becomes crucial. The main function of SSDN Controller management software is to partition SAN, to manage SAN’s topology, to calculate the shortest path between each terminal device and distribute routing. Unified calculating routing eliminates the tedious of single flow measurement and management. At the same time, the unification of the information management level provides us with a rapid management data center-class SAN unique ability. Furthermore, the Telnet user interface of this topic’s management software enables the administrator to partition the SAN in real time and manually control routing.Firstly, this paper systematically introduces the background and task of the topic. Then make a detailed description of the theoretical basis of this subject. And then this paper briefly introduces the SSDN related products. Then paper focuses on the design and implementation of Telnet management software module, partitioning module and controller FSPF module. Finally, this paper introduces the test environment, test procedures and test results of the controller management software.
