【摘要】：大数据已经成为当前学术界和工业界的一个研究热点.但由于计算机系统架构的限制,大数据存储与管理在性能、能耗等方面均面临着巨大的挑战.近年来,一种新型存储介质——相变存储器(phase Change Memory,PCM)——凭着其非易失、字节可寻址、读取速度快、低能耗等诸多优点,为计算机存储体系结构和数据管理设计带来了新的技术变革前景,也为大数据存储和管理带来了新的契机.PCM既是一种非易失存储介质,同时又具备了内存的字节可寻址和高速随机访问特性,模糊了主存和外存的界限,有望突破原有的存储体系架构,实现更高性能的存储与数据管理.概述了PCM存储器的发展现状;总结了目前基于PCM的持久存储技术和基于PCM的主存系统等方面的研究进展;并讨论了PCM在多个领域的应用现状.最后,给出了基于PCM的大数据存储与管理研究的若干未来发展方向,从而为构建新型存储架构下的大数据存储与管理技术提供有价值的参考.
[Abstract]:Big data has become a hot research topic in the academic and industrial circles. But because of the limitation of computer system architecture, data storage and management in the performance, energy consumption and other aspects are facing great challenges. In recent years, a new type of storage medium, phase change memory (phase Change Memory, PCM) - with its non easy, byte addressable, read speed, the advantages of low energy consumption, technological change brought new prospects for computer storage and data management system structure design, but also for large data storage and management has brought a new opportunity for.PCM is a nonvolatile storage medium, but also have the bytes of memory addressable and high-speed random access characteristics, blurring the boundaries between the main memory and disk storage, is expected to exceed the original architecture, storage and data management to achieve higher performance. This paper summarized the development of PCM storage device; Summarizes the current persistent storage technology of PCM and PCM on the main aspects of the system are discussed based on progress based; application of PCM in many fields. Finally, study the data storage and management of the PCM of the future development direction is put forward based on so as to provide valuable reference for large data storage and management Gou Jianxin type storage architecture.
