面向云存储的存储网关

Storage Gateway for the Cloud Storage

对大容量数据存储和快速读写的需求与计算机网络技术的发展,使得网络化存储系统成为网络服务器系统中I/O子系统研究的热点,作为网络存储系统的关键部件,对分布式文件系统的研究具有非常重要的意义.目前开源社区提供了KFS、moosefs、Fast DFS、TFS、GFS[1]等多款分布式文件系统,其中多数提供了基于Linux操作系统的API或者存储网关,却没有提供Windows版的存储网关.主要对分布式文件系统Windows版存储网关的设计框架和思路进行介绍与分析,并实现了一个基于HDFS的Windows版分布式文件系统的存储网关程序dfsclient.

With the development of the computer and network technology, the growing demands for the huge data storage and the high-performance data access make the storage systembasedon network becoming a research hotspot,especially the research of I/O subsystem about network server system. The research about distributed file system as a key part in the network server system is meaningful. Currently open source community provides several DFS（distributed file system） projects, such as KFS, moosefs, Fast DFS, TFS, GFS. Most of projects support only API or storage gateway on Linux system, but not giving support API or storage gateway on Windows system. This study introduces the designing frameworks and the thinking process aboutstorage gateway on Windows system, and then gives a specific example program based on HDFS—dfsclient.
