摘要

非易失性随机存取存储器(NVRAM)被认为是一种很好的替代存储介质,因为它有很多吸引人的特性,包括低空闲能耗、字节可寻址性和短的读/写延迟。此外,还提出了多级单元(MLC) NVRAM,以提供更高的位密度。然而,与单级单元(SLC) NVRAM相比,MLC NVRAM具有较低的能效和较长的写入延迟。这些缺点可能导致基于MLC nvram的存储系统能耗更高。在基于MLC nvram的存储设备上,现有的日志文件系统(JFS)的能耗被放大了,因为JFS的故障保护策略是将相同的数据写入两次。这些观察结果促使我们提出一种多写模式日志文件系统(mwJFS),以缓解MLC NVRAM的缺点,降低基于MLC NVRAM的JFS的能耗。本文提出的mwJFS区分了日志数据的数据保留需求,并采用不同的写模式来提高能源效率和更好的访问性能。通过一系列实验验证了mwJFS在基于MLC nvram的存储系统上的性能。

Enhancing the Energy Efficiency of Journaling File System via Exploiting Multi-Write Modes on MLC NVRAM
Non-volatile random-access memory (NVRAM) is regarded as a great alternative storage medium owing to its attractive features, including low idle energy consumption, byte addressability, and short read/write latency. In addition, multi-level-cell (MLC) NVRAM has also been proposed to provide higher bit density. However, MLC NVRAM has lower energy efficiency and longer write latency when compared with single-level-cell (SLC) NVRAM. These drawbacks could lead to higher energy consumption of MLC NVRAM-based storage systems. The energy consumption is magnified by existing journaling file systems (JFS) on MLC NVRAM-based storage devices due to the JFS's fail-safe policy of writing the same data twice. Such observations motivate us to propose a multi-write-mode journaling file systems (mwJFS) to alleviate the drawbacks of MLC NVRAM and lower the energy consumption of MLC NVRAM-based JFS. The proposed mwJFS differentiates the data retention requirement of journaled data and applies different write modes to enhance the energy efficiency with better access performance. A series of experiments was conducted to demonstrate the capability of mwJFS on a MLC NVRAM-based storage system.
