Learning Ceph - Second Edition

By: Karan Singh, Vaibhav Bhembre, Anthony D'Atri

Overview of this book

Learning Ceph, Second Edition will give you all the skills you need to plan, deploy, and effectively manage your Ceph cluster. You will begin with the first module, where you will be introduced to Ceph use cases, its architecture, and core projects. In the next module, you will learn to set up a test cluster, using Ceph clusters and hardware selection. After you have learned to use Ceph clusters, the next module will teach you how to monitor cluster health, improve performance, and troubleshoot any issues that arise. In the last module, you will learn to integrate Ceph with other tools such as OpenStack, Glance, Manila, Swift, and Cinder. By the end of the book you will have learned to use Ceph effectively for your data storage requirements.

Preface

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 on 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.
