摘要

本文介绍了NVCACHE，这是一种使用非易失性主存储器(NVMM)作为写缓存来提高遗留应用程序的写性能的方法。我们将NVCACHE与为NVMM量身定制的文件系统(Ext4-DAX和NOVA)以及I/ o密集型应用程序(SQLite, RocksDB)进行了比较。我们的评估表明，NVCACHE达到了NVMM现有最先进系统的性能水平，但没有其局限性:NVCACHE不会将存储数据的大小限制在NVMM的大小，并且可以透明地与未修改的遗留应用程序一起工作，即使在源代码不可用的情况下也能提供额外的持久性保证。

NVCache: A Plug-and-Play NVMM-based I/O Booster for Legacy Systems

This paper introduces NVCACHE, an approach that uses a non-volatile main memory (NVMM) as a write cache to improve the write performance of legacy applications. We compare NVCACHE against file systems tailored for NVMM (Ext4-DAX and NOVA) and with I/O-heavy applications (SQLite, RocksDB). Our evaluation shows that NVCACHE reaches the performance level of the existing state-of-the-art systems for NVMM, but without their limitations: NVCACHE does not limit the size of the stored data to the size of the NVMM, and works transparently with unmodified legacy applications, providing additional persistence guarantees even when their source code is not available.
