ConnectX-9 Card technical selection Q&A

Owner-confirmed and documentation-backed questions with explicit variant applicability and source boundaries.

Editorial Team•2026年10月10日

These questions were prepared for technical evaluation from cited documentation. They are not a measured list of frequently asked customer questions. The applicability line belongs to each answer; do not transfer a statement between order-code, firmware, cooling, length, form-factor or crypto variants.

The products listed below are the applicable catalog references. Answers use owner-confirmed manufacturer-origin product data, scoped public documentation, or explicitly stated engineering guidance. Genuine conflicting values are qualified individually.

Is this exact order code mass production?

Applicable catalog candidates: 900-9X91Q-00RC-ST0, 900-9X91Q-00RN-ST0, 900-9X91Q-00RV-ST0.

No such claim is supported. NVIDIA marks this code Prototype in the opened current ordering table.

What does PQC ready mean for deployment?

Applicable catalog candidates: 900-9X91Q-00RC-ST0, 900-9X91Q-00RN-ST0, 900-9X91Q-00RV-ST0.

PQC ready is the wording of the ordering table. It does not by itself establish a particular enabled algorithm, protocol, certification or software configuration; validate those requirements with NVIDIA.

Which server interface is required?

Applicable catalog candidates: 900-9X91Q-00RC-ST0.

The exact row specifies HHHL and PCIe 4 x16 with a tall bracket. The OCP form factor is a separate product and cannot be assumed interchangeable.

Can the headline bandwidth be doubled for two ports?

Applicable catalog candidates: 900-9X91Q-00RC-ST0.

The table states 200Gb/s bandwidth without an independent per-port claim. Do not multiply it by two.

Can the family deployment case validate this prototype SKU?

Applicable catalog candidates: 900-9X91Q-00RC-ST0, 900-9X91Q-00RN-ST0, 900-9X91Q-00RV-ST0.

No. A deployment that names ConnectX-9 validates only the reported family/platform use unless it identifies this exact order code and revision.

What must be confirmed before a production purchase?

Applicable catalog candidates: 900-9X91Q-00RC-ST0, 900-9X91Q-00RN-ST0, 900-9X91Q-00RV-ST0.

Confirm lifecycle, server compatibility, production firmware, cooling and power specifications, complete accessory BOM and the actual batch identity. Published prototype documentation does not confirm stock or shipment.

Which server interface is required?

Applicable catalog candidates: 900-9X91Q-00RN-ST0.

The exact row specifies HHHL and PCIe 6 x16 with a tall bracket. The OCP form factor is a separate product and cannot be assumed interchangeable.

Can the headline bandwidth be doubled for two ports?

Applicable catalog candidates: 900-9X91Q-00RN-ST0.

The exact row lists dual-port 400GbE / 400Gb/s InfiniBand. End-to-end throughput still depends on port configuration, PCIe and the workload.

Which server interface is required?

Applicable catalog candidates: 900-9X91Q-00RV-ST0.

The exact row specifies HHHL and PCIe 5 x16 with a tall bracket. The OCP form factor is a separate product and cannot be assumed interchangeable.

Can the headline bandwidth be doubled for two ports?

Applicable catalog candidates: 900-9X91Q-00RV-ST0.

The table states 400Gb/s bandwidth without an independent per-port claim. Do not multiply it by two.

What distinguishes C9210P from its adjacent OCP variant?

Applicable catalog candidates: 900-9X94Q-00RC-MI0.

C9210P specifies 200Gb/s bandwidth and PCIe 4.0 x16. C9210P specifies 200Gb/s and PCIe 4.0 x16; C9220P specifies 400Gb/s and PCIe 5.0 x16. Both owner-described configurations use OCP 3.0 SFF and internal-lock retention.

Public references: NVIDIA ConnectX-9 SuperNIC User Manual | NVIDIA ConnectX-9 SuperNIC User Manual.

Can it replace the similarly named HHHL card?

Applicable catalog candidates: 900-9X94Q-00RC-MI0.

No automatic substitution is established. C9210P uses OCP 3.0 SFF; the C9210 and C9220 stand-up versions are HHHL cards. Check the server slot, lane routing and retention system.

Public references: NVIDIA ConnectX-9 SuperNIC User Manual | NVIDIA ConnectX-9 SuperNIC User Manual.

Does the bandwidth rating apply independently to each cage?

Applicable catalog candidates: 900-9X94Q-00RC-MI0.

The supplied technical description states 200Gb/s bandwidth and two QSFP112 cages. It does not establish 200Gb/s simultaneously at each cage; obtain the intended port configuration before cable selection.

Public references: NVIDIA ConnectX-9 SuperNIC User Manual | NVIDIA ConnectX-9 SuperNIC User Manual.

Which security options are specified?

Applicable catalog candidates: 900-9X94Q-00RC-MI0, 900-9X94Q-00RV-MI0.

Hardware crypto and secure boot are enabled, and the product is designated PQC Ready. The supplied description does not identify a particular PQC algorithm, firmware version or certification.

Public references: NVIDIA ConnectX-9 SuperNIC User Manual | NVIDIA ConnectX-9 SuperNIC User Manual.

What remains to be qualified for the server?

Applicable catalog candidates: 900-9X94Q-00RC-MI0, 900-9X94Q-00RV-MI0.

Confirm supported network modes, lane routing, power, thermal solution, firmware/PSID and the exact mechanical drawing. Family-level ConnectX-9 documentation is useful context, but it does not establish these values for this OCP code.

Public references: NVIDIA ConnectX-9 SuperNIC User Manual | NVIDIA ConnectX-9 SuperNIC User Manual.

What is the source basis for this exact configuration?

Applicable catalog candidates: 900-9X94Q-00RC-MI0, 900-9X94Q-00RV-MI0.

The exact order code and technical configuration are owner-confirmed manufacturer-sourced product data. Public ConnectX-9 family documentation supplies context; an exact public OCP ordering entry was not located in the sources reviewed.

Public references: NVIDIA ConnectX-9 SuperNIC User Manual | NVIDIA ConnectX-9 SuperNIC User Manual.

What distinguishes C9220P from its adjacent OCP variant?

Applicable catalog candidates: 900-9X94Q-00RV-MI0.

C9220P specifies 400Gb/s bandwidth and PCIe 5.0 x16. C9210P specifies 200Gb/s and PCIe 4.0 x16; C9220P specifies 400Gb/s and PCIe 5.0 x16. Both owner-described configurations use OCP 3.0 SFF and internal-lock retention.

Public references: NVIDIA ConnectX-9 SuperNIC User Manual | NVIDIA ConnectX-9 SuperNIC User Manual.

Can it replace the similarly named HHHL card?

Applicable catalog candidates: 900-9X94Q-00RV-MI0.

No automatic substitution is established. C9220P uses OCP 3.0 SFF; the C9210 and C9220 stand-up versions are HHHL cards. Check the server slot, lane routing and retention system.

The supplied technical description states 400Gb/s bandwidth and two QSFP112 cages. It does not establish 400Gb/s simultaneously at each cage; obtain the intended port configuration before cable selection.
