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 the different storage protocols that exist and how they match to Ceph's capabilities. You also learned the protocols that are best suited for certain roles, and should be able to make informed decisions when selecting them.

Having worked through the examples, you should also have a firm understanding of how to export Ceph storage via iSCSI, NFS, and SMB to enable non-native Ceph clients to consume Ceph storage.

Finally, you should also understand the requirements for being able to design and build a resilient failover cluster that can be used to deliver highly available Ceph storage to non-native clients.

In the next chapter we will look at the different types of RADOS pool types and the different types of Ceph storage which can be provisioned.
