Introduction

This document outlines the steps to deploy SDN-Enabled Broadband Access (SEBA) for Telco Appliance. With the exception of the installation of the SEBA application components (VOLTHA, NEM, ONOS), the installation process follows that of REC (REC Installation Guide). The production deployment of SEBA is intended to be done using the Akraino Regional Controller, but this release focuses on deploying SEBA without the Regional Controller. Instructions on how to deploy the SEBA blueprint using the Regional Controller will be covered in a future release.

The instructions below directly invoke the SEBA Deployer from the BMC, iLO or iDRAC of a physical server. The basic workflow of the SEBA deployer is to copy a base image to the first controller in the cluster and then read the contents of a configuration file (typically called user_config.yaml) to deploy the base OS and all additional software to the rest of the nodes in the cluster.

An overview and diagram of the network connectivity is available on the Radio Edge Cloud Validation Lab page.

Pre-Installation Requirements for SEBA Cluster

Hardware Requirements:

SEBA is a fully integrated stack from the hardware up to and including the application, so for best results it is necessary to use one of the tested hardware configurations. Although SEBA is intended to run on a variety of different hardware platforms, it includes a hardware detector component that customizes each installation based on the hardware present and will need (possibly minor) changes to run on additional hardware configurations. The primary focus of Akraino Release 2 self-certification testing for the SEBA blueprint is the Nokia Open Edge servers, so some issues may be encountered with other server types.

Minimum of 3 nodes.
Total Physical Compute Cores: 60 (120 vCPUs)
Total Physical Compute Memory: 192GB minimum per node
Total SSD-based OS Storage: 2.8 TB (6 x 480GB SSDs)
Total Application-based Raw Storage: 5.7 TB (6 x 960GB SSDs)
Networking Per Server: Apps - 2 x 25GbE (per Server) and DCIM - 2 x 10GbE + 1 1Gbt (shared)

The specific recommended configuration as of the Release 2 time frame is the Open Edge configuration for a single cluster documented in the Radio Edge Cloud Validation Lab, with only three server blades populated (instead of five server blades for REC).

BIOS Requirements:

BIOS set to Legacy (Not UEFI)
CPU Configuration/Turbo Mode Disabled
Virtualization Enabled
IPMI Enabled
Boot Order set with Hard Disk listed as first in the list.

As of Akraino Release 2, the Telco Appliance blueprint family does not yet include automatic configuration for a pre-boot environment. The following versions were manually loaded on the Open Edge servers in the SEBA Blueprint Validation Lab (note: this may be facilitated with the same script utilized by REC for Akraino Release 1). In the future, automatic configuration of the pre-boot environment is expected to be a function of the Regional Controller under the direction of the SEBA pod create workflow script.

BIOS1: 3B06
BMC1: 3.13.00
BMC2: 3.08.00
CPLD: 0x01

Network Requirements:

The SEBA cluster requires the following segmented (VLAN), routed networks accessible by all nodes in the cluster:

External Operations, Administration and Management (OAM) Network
Out Of Band (OOB) (iLO/iDRAC) network(s)
Storage/Ceph network(s)
Internal network for Kubernetes connectivity
NTP and DNS accessibility

The SEBA installer will configure NTP and DNS using the parameters entered in the user_config.yaml. However, the network must be configured for the SEBA cluster to be able to access the NTP and DNS servers prior to the install.

About user_config.yaml

The user_config.yaml file contains details for your SEBA cluster such as required network CIDRs, usernames, passwords, DNS and NTP server ip addresses, etc. The SEBA configuration is flexible, but there are dependencies: e.g., using DPDK requires a networking profile with ovs-dpdk type, a performance profile with CPU pinning & hugepages and performance profile links on the compute node(s). All values in the user_config.yaml should be updated to match the environment for your deployment.

The following link points to the latest user_config template with descriptions and examples for every available parameter: user_config.yaml template

Note: the version number listed in the user_config.yaml needs to follow closely the version from the template. There is a strict version checking during deployment for the first two part of the version number. The following rules apply to the yaml's version parameter:

### Version numbering: ### X.0.0 ### - Major structural changes compared to the previous version. ### - Requires all users to update their user configuration to ### the new template ### a.X.0 ### - Significant changes in the template within current structure ### (e.g. new mandatory attributes) ### - Requires all users to update their user configuration according ### to the new template (e.g. add new mandatory attributes) ### a.b.X ### - Minor changes in template (e.g. new optional attributes or ### changes in possible values, value ranges or default values) ### - Backwards compatible

YAML Requirements

The YAML files need to edited/created using Linux editors or in Windows Notepad++
YAML files do not support TABS. You must space over to the location for the text.

Note: You have a better chance at creating a working YAML by editing an existing file or using the template rather than starting from scratch.

Installing SEBA

Obtaining the ISO Image

Recent builds can be obtained from the Akraino Nexus server. Choose either "latest" or a specific build number from the release images directory and download the file install.iso. Build number 185 is the Akraino Release 1 image from the 4th of October, 2019 and was used for the initial validation of the SEBA blueprint. Options for booting the ISO on your target hardware include NFS, HTTP, or USB memory stick. You must place the ISO in a suitable location (e.g., NFS server, HTTP(S) server or USB memory stick) before starting the boot process. The file bootcd.iso, which is also in the same directory, is used only when deploying via the Akraino Regional Controller using the Telco Appliance Remote Installer. You can ignore bootcd.iso when following the manual procedure below.

Accessing REC.ISO

Nokia OpenEdge Servers

Login to the controller-1 BMC ip using a web browser (https://xxx.xxx.xxx.xxx).

Go to Settings/Media Redirection/General Settings.

Select the Remote Media Support.

Select the Mount CD/DVD.

Type the NFS server IP address.

Type the NFS share path.

Select the nfs in Share Type for CD/DVD.

Click Save.

Click OK to restart the VMedia Service.

Go to Settings/Media Redirection/Remote Images.

Select the image for the first CD/DVD device from the drop-down list.

Click the play button to map the image with the server’s CD/DVD devices. The Redirection Status changes to Started when the image redirection succeeds.

Go to Control & Maintain/Remote Control to open the Remote Console.

Reset the server.

Press F11 to boot menu and select boot from CD/DVD device.

HP Servers

(Future)

Dell Servers

After rebooting, the installation will bring up the Akraino Edge Stack screen.

The first step is to clean all the drives discovered before installing the ISO image.

Select, 0 Set external network at the Installation window, press OK.

Arrow down to and press the spacebar to select the network interface to be used for the external network.

If using bonded nics, select the first interface in the bond.

Enter the external ip address with CIDR for controller-1: 172.28.15.211/24

Enter the gateway ip address for the external ip address just entered: 172.28.15.1

Enter the VLAN number: 141

The installation will check the link and connectivity of the IP addresses entered.

If the connectivity test passed, then Installation window will return.

Uploading user_config.yaml

Go to your RC or jump server and scp (or sftp) your user_config.yaml to controller-1’s /etc/userconfig directory.

initial credentials: root/root.

scp user_config.yaml root@<controller-1 ip address>/etc/userconfig/
