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

...

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)

• 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 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.

You should see: Installation complete, Installation Succeeded.

Go to SEBA Blueprint Test Document and follow the steps outlined there to ensure that all nodes and services were properly deployed.

Deployment Failures

Sometimes failures happen, usually due to misconfigurations or incorrect addresses.
