摘　　要：随着社会的发展和计算机技术遵从摩尔定律的不断进步,大数据、云计算、物联网边缘计算等对海量数据存储提出了更高的要求。基于此,分析RAID技术中各级别的特点,重点论述RAID6及纠删码技术,结合MaximumDistanceSeparable(简称MDS)。在此基础上,提出一种改进的阵列纠删码(iMDS)编码规则,分析iMDS相对其他MDS在负载均衡、编码、更新和译码等方面的优点。With the development of society and the continuous progress of computer technology in compliance with Moore's law, large data, cloud computing, edge computing of the Internet of Things put forward higher requirements for mass data storage. Based on this, the characteristics of RAID technology at all levels are analyzed, and RAID6 and erasure code technology are mainly discussed, combined with Maximum Distance Separable (MDS). On this basis, an improved array erasure code (iMDS) encoding rule is proposed. The advantages of iMDS over other MDS in load balancing, encoding, updating and decoding ar e analyzed.
