摘要

持久性内存(PM)是非易失的字节可寻址内存，它提供的读和写延迟比闪存(如ssd)小几个数量级。本调查讨论了文件系统如何解决持久性内存文件系统实现中最突出的挑战。首先，我们讨论持久性内存的属性如何改变文件系统的设计。其次，我们讨论了旨在优化小文件I/O和相关元数据分辨率的工作。第三，我们讨论了现有的Persistent Memory文件系统是如何实现(元)数据持久性和一致性的。

Persistent Memory File Systems: A Survey

Persistent Memory (PM) is non-volatile byte-addressable memory that offers read and write latencies in the order of magnitude smaller than flash storage, such as SSDs. This survey discusses how file systems address the most prominent challenges in the implementation of file systems for Persistent Memory. First, we discuss how the properties of Persistent Memory change file system design. Second, we discuss work that aims to optimize small file I/O and the associated meta-data resolution. Third, we address how existing Persistent Memory file systems achieve (meta) data persistence and consistency.
