Chapter 1. Introduction

This document describes how to configure OpenStack to use one or more Dell Storage Center back ends. The following sections assume that:

  • You intend to use only Dell Storage Center devices and drivers for Block Storage back ends
  • The OpenStack Overcloud has already been deployed through Director, with a properly-functional Block Storage service
  • The Dell storage device has already been deployed and configured as a storage repository
  • You have the necessary credentials for connecting to the Enterprise Manager and Dell Storage Center Group
  • You have the username and password of an account with elevated privileges. You can use the same account that was created to deploy the Overcloud; in Creating a Director Installation User, we create and use the stack user for this purpose.

When RHEL OpenStack Platform is deployed through the Director, all major Overcloud settings (in particular, the Block Storage service back end) must be defined and orchestrated through the Director as well. This ensures that the settings will persist through any further Overcloud updates. For more information about deploying OpenStack through the Director, see Director Installation and Usage.

The purpose of this document is to explain how to orchestrate your desired Dell Storage Center back end configuration to the Overcloud’s Block Storage service. This document will not discuss the different deployment configurations possible with the back end. Rather, to learn more about the different available deployment configurations, see your device’s product documentation.

Once you are familiar with the resulting back end configuration you want to deploy (and its corresponding settings), refer to this document for instructions on how to orchestrate it through the Director.


At present, the Director only has the integrated components to deploy a single instance of a Dell Storage Center back end. As such, this document only describes the deployment of a single back end.

Deploying multiple instances of a a Dell Storage Center back end requires a custom back end configuration. See the Custom Block Storage Back End Deployment Guide for instructions.
