High Availability Data Storage Scheme for Shipborne Weapon Scheduling System

文章介绍了某舰船武器调度系统高可用数据存储方案,其硬件设计和软件设计均采用热备方式。方案应用在军用船舱中,所设计的硬件既能节省空间又能在多个方面实现冗余,且出现故障时互相不影响。软件设计上采用容错软件将两块计算单元组成双机热备系统;采用同步镜像软件将数据库数据同步存储到两个磁盘阵列;采用连续备份软件将两块计算单元的操作系统和重要数据备份。这种高可用数据存储方案消除了舰船数据库系统中设备或软件单点故障的风险,具有良好的军事意义和社会效益。

This paper introduces a high availability data storage scheme for a ship's weapon scheduling system.The hardware and software designs both adopt a hot standby method.The scheme is applied in military cabins,and the designed hardware can save space and achieve redundancy in multiple aspects,without affecting each other in case of failure.In terms of software design,fault-tolerant software is used to form a dual machine hot standby system with two computing units.It uses synchronous mirroring software to synchronize and store database data on two disk arrays,and uses continuous backup software to backup the operating systems and important data of two computing units.This highly availability data storage scheme eliminates the risk of single point failure of equipment or software in ship database systems,and has good military significance and social benefits.
