云硬盘是IaaS云平台的重要组成部分，云硬盘给虚拟机提供了持久的块存储设备。目前的AWS 的EBS(Elastic Block store)给Amazon的EC2实例提供了高可用高可靠的块级存储卷，EBS适合于一些需要访问块设备的应用，比如数据库、文件系统等。在OpenStack中，可以使用Ceph、Sheepdog、GlusterFS作为云硬盘的开源解决方案，下面我们来了解Ceph的架构。

Key Features Leverage Ceph's advanced features such as erasure coding, tiering, and Bluestore Solve large-scale problems with Ceph as a tool by understanding its strengths and weaknesses to develop the best solutions A practical guide that covers engaging use cases to help you use advanced features of Ceph effectively Book Description Mastering Ceph covers all that you need to know to use Ceph effectively. Starting with design goals and planning steps that should be undertaken to ensure successful deployments, you will be guided through to setting up and deploying the Ceph cluster, with the help of orchestration tools. Key areas of Ceph including Bluestore, Erasure coding and cache tiering will be covered with help of examples. Development of applications which use Librados and Distributed computations with shared object classes are also covered. A section on tuning will take you through the process of optimisizing both Ceph and its supporting infrastructure. Finally, you will learn to troubleshoot issues and handle various scenarios where Ceph is likely not to recover on its own. By the end of the book, you will be able to successfully deploy and operate a resilient high performance Ceph cluster. What you will learn Know when and how to use some of Ceph's advanced new features Set up a test cluster with Ansible and some virtual machines using VirtualBox and Vagrant Develop novel solutions to massive problems with librados and shared object classes. Choose intelligent parameters for an erasure coded pool and set it up. Configure the Bluestore settings and see how they interact with different hardware configurations. Keep Ceph running through thick and thin with tuning, monitoring and disaster recovery advice. About the Author Nick Fisk is an IT specialist with a strong history in enterprise storage.
