Overview of this book

This Learning Path takes you through the basics of Ceph all the way to gaining in-depth understanding of its advanced features. You’ll gather skills to plan, deploy, and manage your Ceph cluster. After an introduction to the Ceph architecture and its core projects, you’ll be able to set up a Ceph cluster and learn how to monitor its health, improve its performance, and troubleshoot any issues. By following the step-by-step approach of this Learning Path, you’ll learn how Ceph integrates with OpenStack, Glance, Manila, Swift, and Cinder. With knowledge of federated architecture and CephFS, you’ll use Calamari and VSM to monitor the Ceph environment. In the upcoming chapters, you’ll study the key areas of Ceph, including BlueStore, erasure coding, and cache tiering. More specifically, you’ll discover what they can do for your storage system. In the concluding chapters, you will develop applications that use Librados and distributed computations with shared object classes, and see how Ceph and its supporting infrastructure can be optimized. By the end of this Learning Path, you'll have the practical knowledge of operating Ceph in a production environment. This Learning Path includes content from the following Packt products: • Ceph Cookbook by Michael Hackett, Vikhyat Umrao and Karan Singh • Mastering Ceph by Nick Fisk • Learning Ceph, Second Edition by Anthony D'Atri, Vaibhav Bhembre and Karan Singh

Introductionc 


The Virtual Storage Manager (VSM) is software originally initiated and developed by Intel for Ceph cluster management; it was later open sourced by Intel under the Apache 2.0 License. Ceph comes with the ceph-deploy CLI tool for cluster deployment, and it also provides a rich CLI for cluster management. VSM, on the other hand, provides a web-based user interface to simplify the creation and management of Ceph clusters. By using the VSM GUI Ceph cluster, the operator can monitor overall cluster health, manage cluster hardware and storage capacity, as well as attach the Ceph storage pools to the OpenStack Cinder.

VSM is developed in Python using OpenStack Horizon as its base for the application framework. It has the familiar look and feel of OpenStack Horizon for both software developers and OpenStack administrators. Some of the key features of VSM include the following:

  • A web-based user interface for easy administration of the Ceph cluster
  • It better organizes and manages the server...
