Research On High Reliability Data Storage Technology

Data storage system will have various problems in the process of work.Causes are various,leading to data loss,damage and system crash.Along with the electronic data amount and data integrity in the system requirements,the reliability of data storage system is particularly important.Therefore,it's necessary to analyze the influential factors of reliability for the data storage system theoretically,and study corresponding solutions.There are three problems in technical means to enhance the reliability of data storage system now.First,for a variety of data storage system architecture and working environment,reliability is necessary,including predictive failure probability,size of the data redundancy and time for use,etc.Second,more appropriate data encoding is required to cope with a variety of data redundancy strategy.Lastly,for high performance real-time system with large data storage and high data read/write speed of,at the same time of data storage reliability design,it should be considered to restore the data of need to consider do not affect the normal work of the system itself.This paper summarized relavant work,including external environment stress influence on data storage system,principle and performance of data encoding and data redundancy,and overall architecture implementation of large fault tolerant system,etc.Moreover,combined with the actual demand of the project,work are carried out in high-performance data detection correction algorithm,high reliability data redundancy strategy and high reliability of data storage system architecture.The achievements are as follows:First,a kind of error correction coding method adapted to system is designed based on the linear block codes principle.This method has better error detection and error correction,and can meet the requirements of real-time high speed data reading and writing system.Second,a kind of data redundancy,vote,detection and recovery of data protection mechanism of high reliability is designed based on the data storage redundancy strategy layout.Its characteristic is high reliability at the expense of storage space and running time.Third,the reliability of the data storage and the efficiency of system and data interaction is enhangced based on a distributed data storage architecture.In this paper,a data storage system was designed with high-performance data correction algorithm and storage architecture of high reliability.It coordinates data storage reliability,system resources and time.Further,it meets the requirements of system running effect.Thus,long-term,stable and reliable operation of the whole system is guaranteed.
