Business Case

• What is the business opportunity?

Samsung wold like to expand ecosystem of vDU to ARM server. There is no fixed customer yet, Samsung got request this expansion from market.

• What are the key features that will make this HW successful in the market?

Running the vDU on ARC compact server (Grace C1 ARM CPU) with PTP and software acceleration.

• Is there proprietary SW in the overall SW enablement plan?

      No proprietary SW included

• Justification for Enablement: (e.g., "Customer demand," "Strategic partnership," "New technology adoption," "Certification requirement")

        New hardware adoption

No Acceleration

• What is the timeline for production rollout of this hardware?

Initial test until end of Feb 2026

• Is the vendor offering samples or loaner machines?

 No

• Any specific cooling or power requirements for the hardware?

 Nothing

• Please provide links to any BOM or Blueprint documents.

  no BP is available yet

Red Hat Product/OS Details

• Target Openshift Version?

           OCP 4.20.z

• Specific Features/Components to be Enabled: (e.g., "Network drivers," "Storage controllers," "GPU acceleration," "Specific firmware features," "Kernel modules")

NVIDIA Arc compact server use sams CPU of GH200 but GPU is located in PCIe slot. Samsung L1 software doesn't use GPU (by Aerial). Even GPU is not being used, RT-kernel can't be used

Technical Requirements & Information

• Please list the new capabilities available in this hardware and any development work needed to enable these capabilities?

Very similar hardware architecture of GH200 except GPU. GH200 already supported from OCP 4.20

• What are the requirements for new capabilities?
• Are there specific test cases for the new capability?

Running vDU with standard kernel and software acceleration

• What are the customer use case(s) that this hardware will be utilized in?

5G vDU

• Are there specific drivers or firmware required from the hardware vendor? (Yes/No)

No

• If yes, please provide links or attach relevant documentation.
• Are they available upstream?
• Are there specific kernel versions or patches required for enablement?
• Are there any known hardware quirks or special configurations needed?

        No special configuration - RH Telco RDS based (there are some deviation)

• Any specific security considerations or requirements for this hardware?

       Nothing

Collaboration & Support

• Is there a direct contact at the hardware vendor for technical support? (Name, Email, Phone)
• What level of engagement is expected from Red Hat teams (e.g., driver development, testing, documentation)?

        New hardware regress test needed

Certification (if applicable)

• Is this hardware in our certification catalogue? (Yes/No)

Not yet

• Please provide a link

Additional Comments/Information

Acceptance criteria

• Install OCP 4.20 with Standard kernel
• Install PTP operator and PTP T-BC worked properly - (RU is connected to DU directly without fronthaul switch)
• Install Samsung vDU workload and workload can run on this server with SR-IOV
