| 摘 要： | 闪存已经是目前使用最为广泛的存储设备。众所周知,闪存对访问模式具有极大的敏感性,比如随机与顺序访问模式、冷热访问模式以及写聚集和分段顺序写模式等。此外,闪存设备的很多部件也对这些访问模式具有较大的敏感性。因此,闪存偏好访问模式的识别技术对闪存存储系统的性能和设计具有重要意义。首先给出闪存存储的偏好模式定义,然后提出了闪存存储系统偏好模式的识别技术。实验表明,所提出的偏好模式识别技术具有很高的准确性。

| Abstract: | Flash memory is the most widely used storage device.Flash memory,as is well-known,has great sensitivity to its access pattern,such as random and sequential access patterns,hot and cold access mode,focused writing and partitioned sequential writing,etc.In addition,many parts of flash device also have higher sensitivity to access patterns.Therefore,the recognition technology of preferred access pattern has great influence on the performance and design of flash storage system.The definition of preferred access pattern of flash storage system was first introduced in this paper,and the re-cognition technology of preferred pattern was followed in detail.The experimental results show that the proposed recognition technology has very high accuracy. |
