摘要

最近，许多企业存储平台都采用了闪存固态硬盘。然而，闪存固态硬盘的特性与硬盘有很大的不同。应当仔细评价现有系统中的IO战略。本文对基于flash的事务处理系统进行了评价。本文选择传统的基于就地更新的文件系统和日志结构的文件系统作为两种写策略的代表。通常，人们认为日志结构的文件系统在闪存ssd上运行得更好。我们的实验表明，在不同的闪存ssd上使用两个文件系统，两个数据库应用程序的性能结果是不同的。我们分析了不同配置下的性能。在此基础上，我们提供了构建基于闪存的数据库系统的经验，以便更好地利用闪存ssd的性能优势。

Early Experience and Evaluation of File Systems on SSD with Database Applications

Flash SSDs are being incorporated in many enterprise storage platforms recently. However, the characteristics of the flash SSD are quite different from that of hard disk. The IO strategies in the existing systems should be carefully evaluated. This paper provides an evaluation on the flash-based transaction processing system. Two file systems, traditional in-place update-based file system and log-structured file system, are selected as the representative of two write strategies. Usually, the log-structured file system is believed to play better on flash SSDs. Our experiment shows that the performance results of two database applications are diverse with two file systems on different flash SSDs. We analyze the performance in different configurations. Based on the analysis, we provide our experience on building the flash-based database system to better utilize the performance benefits of flash SSDs.
