Introduction
============

This document provides guidelines on how to install and
configure the Brahmaputra release of OPNFV when using Fuel as a
deployment tool, including required software and hardware configurations.

Although the available installation options give a high degree of
freedom in how the system is set-up, including architecture, services
and features, etc., said permutations may not provide an OPNFV
compliant reference architecture. This instruction provides a
step-by-step guide that results in an OPNFV Brahmaputra compliant
deployment.

The audience of this document is assumed to have good knowledge in
networking and Unix/Linux administration.

Preface
=======
Before starting the installation of the Brahmaputra release of
OPNFV, using Fuel as a deployment tool, some planning must be
done.

Retrieving the ISO image
------------------------

First of all, the Fuel deployment ISO image needs to be retrieved, the
Fuel .iso image of the Brahmaputra release can be found at <TODO>

Building the ISO image
----------------------

Alternatively, you may build the Fuel .iso from source by cloning the
opnfv/fuel git repository.  To retrieve the repository for the Brahmaputra
release use the following command:

$git clone https://<linux foundation uid>@gerrit.opnf.org/gerrit/fuel

Check-out the Brahmaputra release tag to set the branch to the
baseline required to replicate the Brahmaputra release:

$ git checkout stable/<TODO>

Go to the fuel directory and build the .iso:

$ cd fuel/build; make all

For more information on how to build, please see "OPNFV Build
instructions for - Brahmaputra release of OPNFV when using Fuel as
a deployment tool which you retrieved with the repository at
</fuel/fuel/docs/src/build-instructions.rst> <TODO>

Next, familiarize yourself with Fuel by reading the following documents:

- Fuel planning guide <https://docs.mirantis.com/openstack/fuel/fuel-7.0/planning-guide.html>

- Fuel user guide <http://docs.mirantis.com/openstack/fuel/fuel-7.0/user-guide.html>

- Fuel operations guide <http://docs.mirantis.com/openstack/fuel/fuel-7.0/operations.html>

- Fuel Plugin Developers Guide <https://wiki.openstack.org/wiki/Fuel/Plugins>

Prior to installation, a number of deployment specific parameters must be collected, those are:

#.     Provider sub-net and gateway information

#.     Provider VLAN information

#.     Provider DNS addresses

#.     Provider NTP addresses

#.     Network overlay you plan to deploy (VLAN, VXLAN, FLAT)

#.     How many nodes and what roles you want to deploy (Controllers, Storage, Computes)

#.     Monitoring options you want to deploy (Ceilometer, Syslog, erc.).

#.     Other options not covered in the document are available in the links above


This information will be needed for the configuration procedures
provided in this document.

Help with Hardware Requirements
===============================

Calculate hardware requirements:

Refer to the OpenStack Hardware Compatibility List:
<https://www.mirantis.com/products/openstack-drivers-and-plugins/hardware-compatibility-list/>
for more information on various hardware types available for use.

When choosing the hardware on which you will deploy your OpenStack
environment, you should think about:

- CPU -- Consider the number of virtual machines that you plan to deploy in your cloud environment and the CPU per virtual machine.

- Memory -- Depends on the amount of RAM assigned per virtual machine and the controller node.

- Storage -- Depends on the local drive space per virtual machine, remote volumes that can be attached to a virtual machine, and object storage.

- Networking -- Depends on the Choose Network Topology, the network bandwidth per virtual machine, and network storage.


Top of the rack (TOR) Configuration requirements
================================================

The switching infrastructure provides connectivity for the OPNFV
infrastructure operations, tenant networks (East/West) and provider
connectivity (North/South); it also provides needed connectivity for
the storage Area Network (SAN).
To avoid traffic congestion, it is strongly suggested that three
physically separated networks are used, that is: 1 physical network
for administration and control, one physical network for tenant private
and public networks, and one physical network for SAN.
The switching connectivity can (but does not need to) be fully redundant,
in such case it comprises a redundant 10GE switch pair for each of the
three physically separated networks.

The physical TOR switches are **not** automatically configured from
the Fuel OPNFV reference platform. All the networks involved in the OPNFV
infrastructure as well as the provider networks and the private tenant
VLANs needs to be manually configured.

Manual configuration of the Brahmaputra hardware platform should
be carried out according to the OPNFV Pharos specification:
<https://wiki.opnfv.org/pharos/pharos_specification>

OPNFV Software installation and deployment
==========================================

This section describes the installation of the OPNFV installation
server (Fuel master) as well as the deployment of the full OPNFV
reference platform stack across a server cluster.
