我们在一系列现代文件系统和SSD ftl之上对应用程序性能进行了详细的垂直分析。我们正式制定了ssd客户应该遵循的“不成文合同”以获得高性能，并进行分析以发现违反合同的应用程序和文件系统设计。我们的分析利用了取自真实工作负载和文件系统的非常详细的SSD模拟，深入了解了如何更好地构建应用程序、文件系统和ftl，以实现稳健和可持续的性能。
We perform a detailed vertical analysis of application performance atop a range of modern file systems and SSD FTLs. We formalize the "unwritten contract" that clients of SSDs should follow to obtain high performance, and conduct our analysis to uncover application and file system designs that violate the contract. Our analysis, which utilizes a highly detailed SSD simulation underneath traces taken from real workloads and file systems, provides insight into how to better construct applications, file systems, and FTLs to realize robust and sustainable performance.
