Summary

Release 3 is a snapshot point in the ongoing development of the Radio Edge Cloud blueprint. As in Release 2, most of the code for REC is actually shared with its Telco Appliance (TA) family. The changes specific to REC itself, excluding changes inherited from TA) are trivial and are listed below. The changes to Telco Appliance are mostly the version increments to the upstream projects listed below plus minor bug fixes and the bullet points listed below. Providing an integrated, automated deployment of an interoperable set of upstream projects is a major goal of REC and TA, so these version updates are the primary focus of the release.

Changes since Release 2 (2019-11-18)

New Features

ARM64 Support!
- REC Release 3 supports ARM based CPUs for the first time
- Validated on Wiwnn EP120 openEDGE server using Hawk motherboard with Ampere eMAG Arm v8 8180 32 core processor
- Validated on Lenovo HR330A (1U) and Lenovo HR350A (2U) also using Ampere eMAG 8180
EFI support as needed for ARM based servers
Improved kubelet healthcheck for restoring nodes to service

Fixes

CPU Pooler bugfix https://github.com/nokia/CPU-Pooler/issues/36
PVC handler fix in dynamic local PV provisioner

Upgrade Procedures

Currently REC only supports bare metal installation. In place upgrades are not supported. The upgrade procedure is the same as the initial installation procedure documented in the REC Installation Guide.

Release Data

Radio Edge Cloud Repository

The Radio Edge Cloud repository is quite small and mostly contains simple workflow scripts that allow the Akraino Regional Controller to perform the installation of the Telco Appliance based bare metal installation used by REC.
