The new architecture of FC storage network based on controller

Abstract

With the rapid development of Internet technology and the explosive growth of data, the storage system designed by tightly coupled hardware and software is limiting the development of storage technology severely, and unable to meet the fast changing needs in the mobile Internet and exploding big data era. Software Defined Storage (SDS) as a new storage system architecture is more suitable for the development of the next-generation data centers. This paper proposed a new Controller-based FC Storage Network (CSN) architecture using the idea of SDS technology. CSN decoupling control plane protocol of FC switch from data plane deployed control plane protocol and distributed functions in the controller. This paper described the design and implementation of this architecture and verifies the feasibility through the actual development environment. Finally, as a result of experiments, server can establish a connection with the storage more quickly in CSN, furthermore, CSN has a faster convergence, as well as more reliability and scalability.
