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.

Introduction


Once you have installed and configured your Ceph storage cluster, the next task is performing storage provisioning. Storage provisioning is the process of assigning storage space or capacity to physical or virtual servers, either in the form of block, file, or object storage. A typical computer system or server comes with a limited local storage capacity that might not be enough for your data storage needs. Storage solutions such as Ceph provide virtually unlimited storage capacity to these servers, making them capable of storing all your data and making sure that you do not run out of space. Using a dedicated storage system instead of local storage gives you the much-needed flexibility in terms of scalability, reliability, and performance.

Ceph can provision storage capacity in a unified way, which includes block, filesystem, and object storage. The following diagram shows storage formats supported by Ceph, and depending on your use case, you can select one or more storage options...
