不扯淡了,直接来写吧,一天一共要写三篇博客,还有两篇呢. 1. 这篇博客讲什么? Fast File System(FFS)快速文件系统,基本思想已经在在上一篇博客File System Implementation 里面说明了,FFS是对VSFS的一种优化改进使其可以被实际使用. 2. FFS基于VSFS的改进思想是什么? 这个呢,VSFS在存储文件的时候,根本没有考虑磁盘的寻址时间,把磁盘当做了一种随机存储介质!事实上由于局域性原理的存在,依据局域性而对存储做相应改进是非常有助于性能提升的.…

I researched a lot about storage system classes given at good universities this year. This had two reasons: The first was thispost of a researcher at NetApp, about the missing of a good storage or file system class book and secondly our own storage s…

谷歌三大核心技术(一)The Google File System中文版  The Google File System中文版 译者:alex 摘要 我们设计并实现了Google GFS文件系统,一个面向大规模数据密集型应用的.可伸缩的分布式文件系统.GFS虽然运行在廉价的普遍硬件设备上,但是它依然了提供灾难冗余的能力,为大量客户机提供了高性能的服务.   虽然GFS的设计目标与许多传统的分布式文件系统有很多相同之处,但是,我们的设计还是以我们对自己的应用的负载情况和技术环境的分析为基础的,不管…

The Hadoop Distributed File System (HDFS) is designed to store very large data sets reliably, and to stream those data sets at high bandwidth to user applications. In a large cluster, thousands of servers both host directly attached storage and execu…

A mechanism is provided in a data processing system for reliable asynchronous solid-state device based de-duplication. Responsive to receiving a write request to write data to the file system, the mechanism sends the write request to the file system,…
