GlusterFS缓存机制研究

摘要

Cache strategy is widely applied to parallel file systems to improve file system performance. The paper sketches therncharacteristics of GlusterFS, investigates deeply into GlusterFS cache strategy, and validates through experiments the cache strategy that is analyzed by GlusterFS theory. By comparative experiments with or without caches, it is proven that GlusterFS cache strategy improves the read performance of GlusterFS.%缓存机制在并行文件系统中广泛使用,以提高文件系统的性能.简单介绍GlusterFS文件系统的特点,简叙当前文件系统中的缓存机制研究概况,对GlusterFS缓存机制进行深入研究,并通过实验对GlusterFS理论分析的缓存机制进行验证.通过有缓存和无缓存的实验的对比,证实GlusterFS的缓存机制改进了GlusterFS文件系统的读性能.
