摘　　要：随着高校图书馆数字资源的存储海量化、文件非结构化、访问高发以及大数据与云计算的应用,传统磁盘逐渐无法满足存储需求。鉴于闪存具有高性能、低功耗、体积小等特性,为了支持高校图书馆能有效部署闪存存储系统,比较了PCIe卡存储、混合式存储、全闪存阵列存储这3种主流存储方案的特点、应用场景及改进方式。在各种场景下,测试比较了闪存与旋转磁盘在性能、功耗等方面差异。通过合理部署,闪存存储系统能显著提升高校图书馆服务器的整体性能,为图书馆数字化服务建设提供良好的支撑。With the continuous improvement of university library digital construction,the rotating disk gradually cannot meet the needs.The flash memory has the characteristics of high-performance,low power consumption,small size and so on.In order to support university libraries to deploy flash memory storage system,we compared three essential storage types with PCIe card,hybrid storage and storage of all flash memory array（AFA）in terms of their features,application scenarios and improvement.After testing and comparing their performance and power consumption under various storage scenarios between flash memory and the rotating disk,we conclude that by rational deployment,the flash memory storage system can significantly elevate the overall performance of university libraries＇ server,provide good support for the construction of digital service of the library.
