Mastering Ceph - Second Edition

By: Nick Fisk

Overview of this book

Ceph is an open source distributed storage system that is scalable to Exabyte deployments. This second edition of Mastering Ceph takes you a step closer to becoming an expert on Ceph. You’ll get started by understanding the design goals and planning steps that should be undertaken to ensure successful deployments. In the next sections, you’ll be guided through setting up and deploying the Ceph cluster with the help of orchestration tools. This will allow you to witness Ceph’s scalability, erasure coding (data protective) mechanism, and automated data backup features on multiple servers. You’ll then discover more about the key areas of Ceph including BlueStore, erasure coding and cache tiering with the help of examples. Next, you’ll also learn some of the ways to export Ceph into non-native environments and understand some of the pitfalls that you may encounter. The book features a section on tuning that will take you through the process of optimizing both Ceph and its supporting infrastructure. You’ll also learn to develop applications, which use Librados and distributed computations with shared object classes. Toward the concluding chapters, you’ll learn to troubleshoot issues and handle various scenarios where Ceph is not likely to recover on its own. By the end of this book, you’ll be able to master storage management with Ceph and generate solutions for managing your infrastructure.

Summary

In this chapter, you learned about Ceph's various deployment methods and the differences between them. You will now also have a basic understanding of how Ansible works and how to deploy a Ceph cluster with it. It would be advisable at this point to continue investigating and practicing the deployment and configuration of Ceph with Ansible, so that you are confident enough to use it in production environments. The remainder of this book will also assume that you have fully understood the contents of this chapter in order to manipulate the configuration of Ceph.

You have also learned about the exciting new developments in deploying Ceph in containers running on the Kubernetes platform. Although the Rook project is still in the early stages of development, it is clear it is already a very powerful tool that will enable Ceph to function to the best of its ability while...
