High Availability Data Storage Scheme for Shipborne Weapon Scheduling System
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.
