摘　　要：通过使用固态盘模拟器对SSD的架构与控制算法进行设计与优化,能够节省大量的时间与经济成本。为评估固态盘模拟器功能与性能,在研究固态盘模拟器架构组成与延迟模型等模型的基础上,选取固态盘随机读写场景,对4种典型开源固态盘模拟器与实际固态盘进行比对实验。实验结果表明,模拟器能够在不同层面模拟固态盘行为,降低固件开发对硬件依赖,减少固态盘设计迭代次数。By designing and optimizing the architecture and control algorithm of SSD using the SSD simulator,it can save a lot of time and economic cost.To evaluate the function and performance of the SSD simulator,the basic architecture and model(e.g.latency model)of the SSD simulator were studied.Comparison experiments were performed among four typical open source SSD simulators and an actual SSD in random read and write scenarios.Experimental results show SSD simulator can model SSD behavior at different levels,thus reducing firmware development reliance on hardware and SSD design iteration times.
