摘　　要：通过对当前已有分布式存储中数据放置策略与动态负载平衡算法的研究及学习,本文简单分析了分布式存储架构模型;详细介绍了分布式缓存的问题;研究了哈希算法,并对其容错性和可扩展性进行了分析;分析了虚拟节点的引入原理;并深入研究了基于节点容量感知的负载均衡策略.最后,针对当前分布式存储中数据应用环境中数据分布策略可扩展性以及灵活性的不足,并结合所得的研究成果写出了个人心得,提出一种更加合理的数据分布策略.Based on the current existing distributed storage of data placement strategy and dynamic load balancing algorithm research and study, this article simply analyzes the structure model of distributed storage; Detailed introduces distributed cache problem; Studies the hash algorithm, and the fault tolerance and extendibility are analyzed; Analyzed the virtual node into principle; And in-depth research capacity based on node perception of load balance strategy. Finally, in view of the current data in distributed storage application environment data distribution strategy scalability and lack of flexibility, and combined with the research results of the personal experience writing, this paper puts forward a more reasonable data distribution strategy.
