Abstract

With the rapid development of information technology, the volume of data proliferates, and so does the increasing demand for data reliability. As a result, high-availability network storage systems have been paid more and more attention. In view of the above situation, considering the current research status and development trends in this field, this paper proposes a design and implementation scheme of a high-availability system for storage networks based on PCI Express (PCIe) non-transparent bridge technology and applies it to a dual-controller storage array. It focuses on the design of high-availability network storage and standard network interface based on non-transparent bridges. Finally, through experimental validation and analysis, our solution can accomplish the functions of storage fault handling and I/O forwarding while having the advantages of high bandwidth performance, high availability and high scalability.
