Research On High-speed Parallel Acquisition Storage System Based On Disk Array

As the development of broadband and ultra broadband microwave technology and computer technology, the common data collection and storage systems have been unable to meet the requirements of high bandwidth data acquisition and storage for the modern radar system. So the modern collection and storage system should possess the characteristics of high bandwidth acquisition and large capacity storage. What’s more, Because of the high speed development of technology, it demands that modern collection and storage system can meet the needs of different indicators of radar system through certain extension so that we can shorten the development cycle and cost of the collection and storage system. That is, Modern collection and storage system should have a strong extensibility.For the requirements of the collection and storage system, this paper proposes a high speed parallel acquisition storage system scheme based on disk array. Firstly, this paper analyzes the key technologies of high speed collection and storage system such as: high speed parallel acquisition and synchronization technology, high speed transmission technology, high speed large capacity storage technology and cache technology, and then it puts forward the implementation method of all kinds of technology. Whereafter, this paper proposes a high speed parallel acquisition storage system scheme based on disk array according to the technology above and the existing high-speed collection and storage system, then it carries on the detailed analysis and argumentation about the precept. Based on the scientific research task, we achieve a set of high-speed parallel acquisition and storage system based on disk array, and we introduce the hardware and software implementation of each module in detail, and finially we complete the system test. At the end of the article, we summarize the research content and the innovation points, and the content which needs to be improved in future are proposed.
