摘要
分布式存储系统中,多节点故障出现的概率很高,必须考虑容错问题。RS编码由于性能高、实现简单而被广泛使用。本文介绍了常用的存储容错技术,描述了基于RS编码的存储容错算法,并引入了一个实例进行了详细分析。
Because probability of multi-node failure is very high, the fault-tolerant mechanism must be considered in distributed storage system.RS coding due to the high performance, simple and is widely used.This paper introduces the storage fault-tolerant technology, describes the fault tolerance algorithm based on RS coding, and introduces an example in detail.
