Abstract
========

This document describes how to install the Brahmaputra 3.0 release of
OPNFV when using Fuel as a deployment tool, with an AArch64 (only) target
node pool.

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

This document provides guidelines on how to install and
configure the Brahmaputra 3.0 release of OPNFV when using Fuel as a
deployment tool, with an AArch64 (only) target node pool,
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 AArch64 Brahmaputra 3.0 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
ArmbandFuel .iso image of the AArch64 Brahmaputra release can be found
at *Reference: 2*

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

Alternatively, you may build the ArmbandFuel .iso from source by cloning the
opnfv/armband git repository. To retrieve the repository for the AArch64
Brahmaputra 3.0 release use the following command:

.. code-block:: bash

    $ git clone https://gerrit.opnfv.org/gerrit/armband

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

.. code-block:: bash

    $ git checkout brahmaputra.3.0

Go to the armband directory and build the .iso:

.. code-block:: bash

    $ cd armband
    $ make release

For more information on how to build, please see *Reference: 14*

Other preparations
------------------

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

- Fuel planning guide, please see *Reference: 8*

- Fuel user guide, please see *Reference: 9*

- Fuel operations guide, please see *Reference: 10*

- Fuel Plugin Developers Guide, please see *Reference: 11*

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:

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.

Install Fuel master
-------------------
#. Mount the Brahmaputra Fuel ISO file/media as a boot device to the jump host server.

#. Reboot the jump host to establish the Fuel server.

   - The system now boots from the ISO image.

   - Select "Fuel Install (Static IP)" (See figure below)

   - Press [Enter].

   .. figure:: img/grub-1.png

#. Wait until screen Fuel setup is shown (Note: This can take up to 30 minutes).

#. Start the installation.

   - Select Quit Setup and press Save and Quit.

   - Installation starts, wait until the login screen is shown.


Boot the Node Servers
---------------------

After the Fuel Master node has rebooted from the above steps and is at
the login prompt, you should boot the Node Servers (Your
Compute/Control/Storage blades (nested or real) with a PXE booting
scheme so that the FUEL Master can pick them up for control.

#. Enable PXE booting

   - For every controller and compute server: enable PXE Booting as the first boot device in the BIOS boot order menu and hard disk as the second boot device in the same menu.

#. Reboot all the control and compute blades.

#. Wait for the availability of nodes showing up in the Fuel GUI.

   - Connect to the FUEL UI via the URL provided in the Console (default: https://10.20.0.2:8443)

   - Wait until all nodes are displayed in top right corner of the Fuel GUI: Total nodes and Unallocated nodes (see figure below).

OPTIONAL - UNTESTED - Set Local Mirror Repos
---------------------------------

**NOTE**: AArch64 Brahmaputra 3.0 does not fully support local Ubuntu mirrors,
or at least does not ship with arm64 packages in local repos by default.
In order to use local (partial) Ubuntu mirrors, one should add arm64 packages
by hand to the existing amd64 mirrors and re-generate repo metadata.
Local MOS/Auxiliary repos contain packages for both amd64 and arm64.

**NOTE**: Below instruction assume you already added (by hand) arm64
Ubuntu necessary packages to the local repository!

The following steps can be executed if you are in an environment with
no connection to the Internet. The Fuel server delivers a local repo
that can be used for installation / deployment of openstack.

#. In the Fuel UI of your Environment, click the Settings Tab and select General from the left pane.

   - Replace the URI values for the "Name" values outlined below:

   - "ubuntu" URI="deb http://<ip-of-fuel-server>:8080/mirrors/ubuntu/ trusty main"

   - "ubuntu-security" URI="deb http://<ip-of-fuel-server>:8080/mirrors/ubuntu/ trusty-security main"

   - "ubuntu-updates" URI="deb http://<ip-of-fuel-server>:8080/mirrors/ubuntu/ trusty-updates main"

   - "mos" URI="deb http://<ip-of-fuel-server>::8080/liberty-8.0/ubuntu/x86_64 mos8.0 main restricted"

   - "Auxiliary" URI="deb http://<ip-of-fuel-server>:8080/liberty-8.0/ubuntu/auxiliary auxiliary main restricted"

   - Click <Save Settings> at the bottom to Save your changes

Target specific configuration
-----------------------------

#. Set up targets for provisioning with non-default "Offloading Modes"

   Some target nodes may require additional configuration after they are
   PXE booted (bootstrapped); the most frequent changes are in defaults
   for ethernet devices' "Offloading Modes" settings (e.g. some targets'
   ethernet drivers may strip VLAN traffic by default).

   If your target ethernet drivers have wrong "Offloading Modes" defaults,
   in "Configure interfaces" page (described above), expand affected
   interface's "Offloading Modes" and [un]check the relevant settings
   (see figure below):

   .. figure:: img/offloadingmodes.png

#. Set up targets for "Verify Networks" with non-default "Offloading Modes"

   **NOTE**: Check *Reference 15* for an updated and comprehensive list of
   known issues and/or limitations, including "Offloading Modes" not being
   applied during "Verify Networks" step.

   Setting custom "Offloading Modes" in Fuel GUI will only apply those settings
   during provisiong and **not** during "Verify Networks", so if your targets
   need this change, you have to apply "Offloading Modes" settings by hand
   to bootstrapped nodes.

   **E.g.**: Our driver has "rx-vlan-filter" default "on" (expected "off") on
   the Openstack interface(s) "eth1", preventing VLAN traffic from passing
   during "Verify Networks".

   - From Fuel master console identify target nodes admin IPs (see figure below):

     .. code-block:: bash

         $ fuel nodes

     .. figure:: img/fuelconsole1.png

   - SSH into each of the target nodes and disable "rx-vlan-filter" on the
     affected physical interface(s) allocated for OpenStack traffic (eth1):

     .. code-block:: bash

         $ ssh root@10.20.0.6 ethtool -K eth1 rx-vlan-filter off

   - Repeat the step above for all affected nodes/interfaces in the POD.

Verify Networks
---------------

It is important that the Verify Networks action is performed as it will verify
that communicate works for the networks you have setup, as well as check that
packages needed for a successful deployment can be fetched.

#. From the FUEL UI in your Environment, Select the Networks Tab and select "Connectivity check" on the left pane (see figure below)

   - Select <Verify Networks>

   - Continue to fix your topology (physical switch, etc) until the "Verification Succeeded" and "Your network is configured correctly" message is shown

   .. figure:: img/verifynet.png


Deploy Your Environment
-----------------------

38. Deploy the environment.

    - In the Fuel GUI, click on the "Dashboard" Tab.

    - Click on <Deploy Changes> in the "Ready to Deploy?" section

    - Examine any information notice that pops up and click <Deploy>

    Wait for your deployment to complete, you can view the "Dashboard"
    Tab to see the progress and status of your deployment.

Installation health-check
=========================

#. Perform system health-check (see figure below)

    - Click the "Health Check" tab inside your Environment in the FUEL Web UI

    - Check <Select All> and Click <Run Tests>

    - Allow tests to run and investigate results where appropriate

    - Check *Reference 15* for known issues / limitations on AArch64, like
      unsupported migration tests when using a GICv3 interrupt controller
