Introduction

Ceph is open-source, which allows many vendors to provide Ceph-based software for defining appropriate storage systems. This document describes how to integrate OpenStack Train with Ceph on a Kunpeng server running openEuler 22.03.

In the virtualization field, Ceph is the most popular open-source storage solution in the OpenStack ecosystem. One of the design principles of OpenStack project is flexibility and scalability. The background of each member project is different, which causes each project to make different choices when a storage system is involved. In this case, Ceph can be used as an ideal unified storage backend for OpenStack. Ceph is a reliable, auto-rebalancing, and auto-recovery scale-out storage system. Based on application scenarios, Ceph can be divided into object storage, block device and file system services. Ceph provides unified scale-out storage with self-healing and intelligent fault prediction functions. It has become one of the most widely accepted standards of software-defined storage.
