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.

The dynamics of capacity, performance, and cost


Ceph is a software-defined storage solution that is designed to run on commodity hardware. This ability of Ceph makes it a flexible and economic solution that is tailored for your needs. Since all the intelligence of Ceph resides in its software, it requires a good set of hardware to make it an overall package that is a great storage solution.

The Ceph hardware selection requires meticulous planning based on your storage needs and the use case that you have. Organizations need optimized hardware configurations that allow them to start small and scale to several petabytes. The following diagram represents a few factors that are used to determine an optimal configuration for your Ceph cluster:

Different organizations have different storage workloads that generally require some middle-ground shared by performance, capacity, and TCO. Ceph is a unified storage, that is, it can provision File, Block, and Object storage from the same cluster. Ceph is...
