摘要
随着飞行器数据规模扩大,数据存储成为核心技术。针对某飞行器地面自主保障信息系统海量数据存储需求,通过软件定义虚拟化存储,设计了一种采用完全对称架构和改进哈希算法的数据存储系统,系统无单点故障,具有很高的数据存储安全性,存储架构对称,容量可无限扩展,算法改进后,读写速度和负载均衡性能明显提高。
With the expansion of data scale of aerocraft,data storage becomes the core technology. In order to meet the requirement of massive data storage for the Autonomous Logistics System of a certain aerocraft,one data storage system using a fully symmetrical architecture and an improved Hash algorithm is designed by defining virtualized storage through software. Without a single point of failure in the system,the security of data storage can be enhanced extremely,and with symmetrical storage architecture,the capacity can be expanded indefinitely. After the algorithm is improved,the performance of read-write speed and load balancing is also improved significantly.
