This document outlines the steps to deploy Radio Edge Cloud (REC) cluster. It has a minimum of three controller nodes. Optionally it may include worker nodes if desired. REC was designed from the ground up to be a highly available, flexible, and cost-efficient system for the use and support of Cloud RAN and 5G networks. The production deployment of Radio Edge Cloud is intended to be done using the Akraino Regional Controller which has been significantly enhanced during the Akraino Release 1 timeframe, but for evaluation purposes, it is possible to deploy REC without the Regional Controller. Regardless of whether the Regional Controller is used, the installation process is cluster oriented. The Regional Controller or a human being initiates the process on the first controller in the cluster, then that controller automatically images every other server in the cluster using IPMI and Ironic (from OpenStack) to perform a zero touch install.
In a Regional Controller based deployment, the Regional Controller API will be used to upload the REC Blueprint YAML (available from the REC repository) which informs the Regional Controller of where to obtain the REC ISO images, the REC workflows (executable code for creating, modifying and deleting REC sites) and the REC remote installer component (a container image which will be instantiated by the create workflow and which will then invoke the REC Deployer (which is located in the ISO DVD disc image file) which conducts the rest of the installation.

Although the purpose of the Radio Edge Cloud is to run the RAN Intelligent Controller (RIC), the Akraino Release 1 predates the RIC release 1. The manual installation procedure described below does not result in the installation the RIC software (which was written from scratch starting in the spring of 2019) is not quite stable enough yet to incorporate into the REC ISO image. The manual installation procedure described below does not result in the installation of the RIC. In the REC Continuous Deployment system, as of the Akraino Release 1 and 2 timeframe, a Jenkins job deploys a "Release Zero" snapshot of the RIC and runs a small set of tests. These steps may be manually executed and this procedure is described in the last section of this WIKI document. Fully automated installation of the RIC as part of the REC will not be complete until sometime after Akraino Release 1in 2020. If you are interested in actually interfacing a REC appliance with eNodeB/gNode B and radio infrastructure you should really join the Radio Edge Cloud Project Meetings on a weekly basis and let the REC team know of your interest. We will be happy to coordinate with you and welcome any testing that you can do. |

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 9 is the Akraino Release 1 image from the 30th of May, 2019. Note that build number 9 is known to NOT work on Dell servers or any of the ARM options listed below. If attempting to install on Dell servers, it is suggested to use builds from no earlier than June 10th. 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.

Nokia OpenEdge ServersUsing the BMC, configure a userid and password on each blade and ensure that the VMedia Access checkbox is checked. The expected physical configuration as described in Radio Edge Cloud Validation Lab is that each server in the cluster has two SSD 480GB SATA 1dwpd M.2 2280 on a riser card inside the server and two SSD 960GB SATA 3dwpd 2.5 inch on the front panel. There is no RAID configuration used. The reference implementation in the Radio Edge Cloud Validation Lab uses one M.2 drive as the physical volume for LVM and both 2.5 inch SSDs as Ceph volumes. |

Dell ServersProvision the disk configuration of the server via iDRAC such that the desired disks will be visible to the OS in the desired order. The installation will use /dev/sda as the root disk and /dev/sdb and /dev/sdc as the Ceph volumes. |

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. |
