1. Proposed title of this feature request

Support of ARM-based servers (ARM64) in the Telco RAN Reference Design Specification.

2. What is the nature and description of the request?

The latest Telco Engineering RAN Reference Design Specification (OCP 4.14) for the RAN DU model targets only systems equipped with 3rd (or later) Generation Xeon CPUs. The aim of this request is to add the Ampere Altra Family as an option for the CPU that will run RAN DU profiles. 

The Ampere Altra family is based on Arm v8.2+ 64-bit CPU cores. The primary hardware platform that will be used for running DU workload by telco partner is the HPE Proliant RL300 Gen11 with Ampere Altra Max (128-cores), which is certified to run on OCP 4.13+.

The RAN Reference Design Specification should cover all Engineering Considerations with the Ampere Altra Family, such as Measured KPI results, Resources and Resource Utilization, as well as all components defined currently in the document.

3. Why does the customer need this? (List the business requirements here)

Major telco partners are planning to run their RAN DU workload on ARM-based servers.
