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

Network settings


Most operating systems are not prepared to efficiently handle very heavy network traffic out of the box. You will need to consult with your networking team in the right settings for your infrastructure and adapt to your kernel, Linux distribution, and network environment. In this section, we'll discuss several common changes that can benefit Ceph deployments.

Jumbo frames

We've mentioned before the value of Jumbo frames to increase performance by increasing network and protocol efficiency. A common raised MTU size is 9,000 bytes; this must be configured within your network infrastructure as well as your system's interface configuration. Depending on your distribution, you may configure this in /etc/network/interfaces or, interface-specific files like /etc/sysconfig/network-scripts/ifcfg-eth0.
