Chapter 1. Introduction

This document describes how to configure OpenStack to use a Fujitsu ETERNUS Disk Storage System as a back end for the Block Storage service. In particular, this document covers how to define a fibre channel and iSCSI back end provided by an ETERNUS device on an overcloud deployment. This will involve defining both back ends as a custom back end for the Block Storage service.

The following sections assume that:

  • A Red Hat OpenStack Platform overcloud has already been deployed through the director.
  • You intend to use only Fujitsu ETERNUS Disk Storage System devices and drivers for Block Storage back ends.
  • You can use the director installation user, which is created as part of the overcloud deployment. See Creating a Director Installation User (from Director Installation and Usage) for more information.
  • You have access to an Admin account on the ETERNUS device; that is, you can log in using an account with the Admin role through the ETERNUS Web GUI or CLI.
  • The Block Storage will be installed on Controller nodes (default).

You can use either Fibre Channel or iSCSI interfaces with a Fujitsu ETERNUS device. Each interface has its own settings and driver: Red Hat supports the use of both interfaces (and their respective drivers) with OpenStack.
