Learning Ceph

Ceph Components and Services

Introduction

This chapter covers Ceph's components, services, and how they work together:

  • The daemons and components that make up the Ceph backend:
    • RADOS
    • Monitors (MONs)
    • OSDs
    • Ceph Manager
    • RGW
  • The services presented to users:
    • Block
    • Object
    • File

We'll describe each in turn, and what they mean to Ceph admins and users. This sets the stage for topics covered in the following chapters:

Core components

One of Ceph's advantages over other storage solutions is the wide and extensible range of services that can be offered with a single backend to manage.

Reliable Autonomic Distributed Object Store (RADOS)

Ceph's foundation is a low-level data store named RADOS that provides a common backend for multiple user-consumable services.

RADOS is an object storage system layer that provides a data durability and availability framework that all user-facing Ceph services are layered atop. RADOS is:

  • Highly available with no single point of failure (SPoF)
  • Reliable and resilient
  • Self-healing
  • Self-managing
  • Adaptive
  • Scalable
  • Not found on the Galactica

RADOS manages the distribution of data within Ceph. Durability...

Core services

Ceph provides four distinct interfaces to its common storage back end, each designed for a specific type of use case. In this section, we'll describe each and offer a real-world example of how it is used.

RADOS Block Device (RBD)

The RBD service is perhaps the most familiar, and at many sites is the primary or even only application of Ceph. It presents block (also known as volume) storage in a fashion that with traditional HDD/SDD applications can consume with little or no adjustment. In this way, it is somewhat analogous with facets of VxVM (™), Solaris Disk Suite (SVM)(), the Linux MD/LVM system, ISCSI or Fibre Channel () appliance, or even a ZFS () ZVOL. RBD volumes, however...

Summary

In this chapter we have touched on the required and optional components of your Ceph cluster, and the services they provide. In the following chapters, we'll help you select the right hardware for your own deployment, explore a number of crucial decisions and dependencies, and proceed through virtual deployment and common maintenance and monitoring tasks.

Key benefits

  • •Explore Ceph's architecture in order to achieve scalability and high availability
  • •Learn to utilize Ceph efficiently with the help of practical examples
  • •Successfully implement Ceph clusters to scale-out storage solutions along with outstanding data protection

Description

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.

Who is this book for?

A basic knowledge of GNU/Linux, and storage systems, and server components is assumed. If you have no experience of software-defined storage solutions and Ceph, but are eager to learn about them, this is the book for you.

What you will learn

  • •The limitations of existing systems and why you should use Ceph as a storage solution
  • •Familiarity with Ceph s architecture, components, and services
  • •Instant deployment and testing of Ceph within a Vagrant and VirtualBox environment
  • •Ceph operations including maintenance, monitoring, and troubleshooting
  • •Storage provisioning of Ceph s block, object, and filesystem services
  • •Integrate Ceph with OpenStack
  • •Advanced topics including erasure coding, CRUSH maps, and performance tuning

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
