航空电子系统的云存储技术研究

Research on Cloud Storage Technology of Avionic System

传统单服务器的分布式存储系统很难满足航空电子系统对实时性的要求,使用云存储技术可以有效提高数据的访问速度。设计了一种适合航空电子系统数据访问特征的云存储方案,用于提高数据访问的实时性。将数据分散地存储在多个服务器上,将任务依据数据存储的特征分解成多个子任务,由子任务并发访问多个服务器,从而提高数据访问的实时性。测试结果表明,多机协同的云存储系统比传统单机工作的存储系统具有更高的访问速度。

Traditional single server distributed storage system is difficult to meet the real-time requirements of the avionic system.The cloud storage technology can effectively improve the speed of data access.In order to improve the real-time performance of data access a cloud storage scheme suitable for avionic system is designed.The data is distributed and stored in multiple servers and the task is decomposed into multiple subtasks according to the characteristics of data storage.The subtasks can access multiple servers simultaneously so as to improve the real-time performance of data access.The experimental results show that the cloud storage system with multi-machine cooperation has higher access speed than the traditional single machine storage system does.
