SDN-based network control method for distributed storage systems

With the increasing need for effective storage management due to ever-growing content-generation over the Internet, Distributed Storage Systems (DSS) has arisen as a valuable tool. Although DSS has considerably improved in the past years, it still leverages legacy techniques in its networking. To cope with the demanding requirements, Software Defined Networking (SDN) has revolutionized the way we manage networks and can significantly help in improving DSS network management. In this paper, we propose an SDN-based network control method that is capable of handling DSS network management and improving its performance. This paper presents the design, implementation, and evaluation using an emulated environment of a typical Data Center Network (DCN) deployment. The experiment results show that by applying the proposed method, DSS can increase the performance and service resilience compared to existing solutions.
