摘　　要：引入新颖固态存储技术和DRAM与固态硬盘(SSD)混合的缓存架构,提出一种海量存储系统的二级缓存策略,通过回写策略能够有效减少SSD缓存的小写问题,并对两级缓存架构下建立的逻辑磁盘进行测试,结果表明在请求平均响应时间上取得了优化。With the introduction of the novel solid-state storage technology and the hybrid cache architecture using DRAM and solid state drive （ SSD） , this paper presents a kind of two-level cache for mass storage system strategy , which effectively reduces SSD caching lowercase problem by write-back strategy , and the logical disk created by two-level cache architecture is tested .The results show that the average response time of the request is optimized .

关 键 词：海量存储 固态硬盘 二级缓存 读写机制
