Gluster 文件系统架构 简介 GlusterFS is a scalable open source clustered file system that offers a global namespace, distributed front end, and scales to hundreds of petabytes without difficulty. By leveraging commodity hardware, Gluster also offers extraordinary cost advantages benefits that are unmatched in the industry. GlusterFS is the core of the integrated Gluster Storage Platform software stack. GlusterFS 是一个提供全局名字空间的开放资源的集群文件系统，前段分布，轻松横跨数百PB级数据存储的产品。通过杠杆式的扩展硬件，Gluster还能代来非凡的无与伦比的成本优势。GlusterFS是整合Gluster存储平台软件组合的核心。 In this paper, we discuss the key architectural components of GlusterFS and how these components impact production deployments on a daily basis. 在这份资料中，我们着重讨论GlusterFS核心的架构组件和这些组件是如何每天影响我们的产品的 At the heart of the design is a completely new view of how storage architecture should be done. The result is a system that scales linearly, is highly resilient, and offers extraordinary performance. Additionally, Gluster brings compelling economics by deploying on low cost commodity hardware and scaling horizontally and performance and capacity requirements grow. The Gluster Storage Platform integrates GlusterFS with an operating system layer and web-based management and installation tool, simplifying the task of deploying petabyte-scale clustered storage to two steps and just a few mouse clicks. 全新的设计核心是存储架构如何设立。结果是造就了线性的系统，高弹性和非凡性能的产品。另外，Gluster通过低成本的硬件设计，水平缩放以及性能和容量的增长需求带来了引人注目的经济性。Gluster存储平台结合GlusterFS和系统层基于web管理和安装工具，只需简单几步即可轻易的部署PB级的存储集群工作。 线性增长 Storage doesn‘t scale linearly. This seems somewhat counter-intuitive on the surface since it is so easy to simply purchase another set of disks to double the size of available storage. The caveat in doing so is that the scalability of storage has multiple dimensions, capacity being only one of them. 存储不能线性的扩容。这看起来就像那些表面上容易简单的通过购买磁盘来扩充存储的可用容量。需要知道的是可扩展性存储在成倍的增长的时候容量只是其中的一个因素 Adding capacity is only one dimension, the systems managing those disks need to scale as well. There needs to be enough CPU capacity to dr
