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 you deploy RHOSP with the director, you must also define and orchestrate all major overcloud settings with the director. This ensures that the settings persist through any further overcloud updates. For more information about deploying RHOSP with the director, see the Director Installation and Usage guide.

This document explains how to orchestrate your Dell Storage Center back end configuration to the Block Storage service on the overcloud. This document does not discuss the different deployment configurations that are possible with the back end. For more information about the different deployment configurations that are available, see the product documentation for your device.

Note

Director has the integrated components to deploy only a single instance of a Dell Storage Center back end.

Deploying multiple instances of a Dell Storage Center back end requires a custom back end configuration. For more information, see the Custom Block Storage Back End Deployment Guide.
