摘　　要：纠删码技术广泛应用于分布式存储系统,以保证数据高效可靠存储。在数据存储过程中,纠删码存储系统需要执行数据读写、传输和编解码操作,主要采用RS(Reed-Solomon Code)编码、再生码(Regeration Code,RGC码)、局部修复码(Locally Repairable Code,LRC码)等编码方法。在实际应用中形成了Jerasure、ISA、LRC、SHEC、Clay等常用纠删码方案来适应不同的应用场景。通过分析验证各分布式存储纠删码方案的性能差异,为存储系统设计人员在实际应用中选择适合的纠删码实现方案提供思路。Erasure codes are widely used in distributed storage systems to ensure reliable and efficient data storage.In the process of data storage,erasure code storage system needs to perform data read-write operation,data encoding and transmission operation,mainly using encoding methods such as reed-solomon code(RS Code),regeneration code(RGC Code),and locally repairable code(LRC Code).In practical applications,common erasure coding schemes like Jerasure,ISA,LRC,SHEC,and Clay have been formed to adapt to different application scenarios.This paper analyzes and verifies the performance differences among various distributed storage erasure coding solutions,aiming to provide insights for storage system designers when selecting a suitable data repair implementation scheme in practical applications.
