摘 要：新型的非易失性存储器（NVM）技术的发展带来了几乎与传统DRAM 一样的存储性能，这使以往内存、磁盘的二元结构变成内存、NVM 及磁盘的数据传输结构，在此情况下出现了多种缓冲数据流的路径。因此文章介绍了管理和设计由DRAM、NVM 和SSD 组成的多层数据缓冲路径。文章利用NVM 特性的多层缓冲数据路径，完成数据缓冲时间的设计。同时提出了用于评估不同数据流完成时间的评价模型，最后提出了一个圆形系统，用于检测目标工作量和系统时间成本模型。

Abstract：The development of new nonvolatile memory（NVM）technology has brought almost the same storage performance as traditional DRAM，which makes the binary structure of memory and disk become the data transmission structure of memory，NVM and disk. In this case，there are many kinds of buffered data flow paths. Therefore，this paper introduces the management and design of multi-layer data buffer path composed of DRAM，NVM and SSD. In this paper，the design of data buffer time is completed by using NVM characteristic of multi-layer buffer data path. At the same time，an evaluation model is proposed to evaluate the completion time of different data streams. Finally，a circular system is proposed to detect the target workload and system time cost model.
