Ceph Cookbook

Overview of this book

Ceph is a unified, distributed storage system designed for excellent performance, reliability, and scalability. This cutting-edge technology has been transforming the storage industry, and is evolving rapidly as a leader in software-defined storage space, extending full support to cloud platforms such as Openstack and Cloudstack, including virtualization platforms. It is the most popular storage backend for Openstack, public, and private clouds, so is the first choice for a storage solution. Ceph is backed by RedHat and is developed by a thriving open source community of individual developers as well as several companies across the globe. This book takes you from a basic knowledge of Ceph to an expert understanding of the most advanced features, walking you through building up a production-grade Ceph storage cluster and helping you develop all the skills you need to plan, deploy, and effectively manage your Ceph cluster. Beginning with the basics, you’ll create a Ceph cluster, followed by block, object, and file storage provisioning. Next, you’ll get a step-by-step tutorial on integrating it with OpenStack and building a Dropbox-like object storage solution. We’ll also take a look at federated architecture and CephFS, and you’ll dive into Calamari and VSM for monitoring the Ceph environment. You’ll develop expert knowledge on troubleshooting and benchmarking your Ceph storage cluster. Finally, you’ll get to grips with the best practices to operate Ceph in a production environment.

Planning the Ceph deployment


A Ceph storage cluster is created on top of the commodity hardware. This commodity hardware includes industry standard servers loaded with physical disk drives that provide storage capacity and some standard networking infrastructure. These servers run standard Linux distributions and Ceph software on top of them. The following diagram helps you understand a basic view of a Ceph cluster:

As explained earlier, Ceph does not have a very specific hardware requirement. For the purpose of testing and learning, we can deploy a Ceph cluster on top of virtual machines. In this section and in the later chapters of this book, we will be working on a Ceph cluster which is built on top of virtual machines. It's very convenient to use a virtual environment to test Ceph, as it's fairly easy to set up and can be destroyed and recreated any time. It's good to know that a virtual infrastructure for the Ceph cluster should not be used for a production environment, and you might face serious problems with this.
