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.

Preface

Ceph, a unified, highly resilient, distributed storage system that provides block, object, and file access, has enjoyed a surge in popularity over the last few years. Due to being open source, Ceph has enjoyed rapid adoption by both developers and end users alike, with several well-known corporations being involved in the project. With every new release, the scale of its performance and feature set continue to grow, further enhancing Ceph's status.

With the current demands for ever-increasing data storage, and the challenges faced by legacy RAID-based systems, Ceph is well placed to offer an answer to these problems. As the world moves toward adopting new cloud technologies and object-based storage, Ceph is ready and waiting to be the driving force behind the new era of storage technologies.

In this book, we will cover a wide variety of topics, from installing and managing a Ceph cluster, through to how to recover from disasters, should you ever find yourself in that situation. For those that have interest in getting their applications to talk directly to Ceph, this book will also show you how to develop applications that make use of Ceph's libraries, and even how to perform distributed computing by inserting your own code into Ceph. By the end of this book, you will be well on your way to mastering Ceph.

The second edition of Mastering Ceph now includes updates around the new BlueStore technology introduced in the Luminous release, with guides to help you understand BlueStore and upgrade your existing cluster to take advantage of it.
