Confirm model, interface type, rate, power, airflow and software version before ordering.
Procurement answer
MCX653106A-HDAT-SP must be handled as a complete ordering identity. The retained page lists a dual-port ConnectX-6 VPI adapter with HDR and Ethernet rates through 200GbE, two QSFP56 ports and PCIe 4.0 x16. It does not explain what the -SP suffix changes, so a buyer should not treat the unsuffixed MCX653106A-HDAT as interchangeable without current model-level evidence.
What the retained record does and does not establish
| Area | Retained evidence | Required verification |
|---|---|---|
| Complete OPN | MCX653106A-HDAT-SP | Manufacturer or supplier document maps this exact suffix to the offered item |
| Network ports | Two QSFP56 ports | Both intended ports, modes and media are represented in the test plan |
| Listed modes | HDR and HDR100; Ethernet through 200GbE | Endpoint, firmware, FEC and media support each deployed mode |
| Host interface | PCIe 4.0 x16; 16.0 GT/s is stated | Server slot, lane width, BIOS and NUMA placement are recorded |
| Suffix meaning | Not defined in the retained page | Current exact-OPN documentation is attached before approval |
Suitable and unsuitable use
- Suitable for evaluation: the offered hardware and documentation both carry the full
MCX653106A-HDAT-SPidentity and the target host and network matrix is known. - Hold for clarification: a quote drops the suffix, substitutes another OPN, or provides only family-level specifications.
- Not ready to order: the project assumes the suffix is cosmetic, relies only on connector matching, or has not identified media for both ports.
Comparison with MCX653106A-HDAT
The two retained pages state the same high-level port, rate, PCIe and adapter-family values. That is evidence of shared listed attributes, not proof that the full OPNs are equivalent. Compare official ordering descriptions, hardware revision, firmware support, region or bundle conditions if documented, package labels and server qualification. Where no authoritative difference record is available, keep the two items separate and test the exact supplied unit.
Full-OPN procurement checklist
- Require the quote, packing list and device label to show
MCX653106A-HDAT-SPin full. - Attach the current exact-OPN specification or support-matrix entry; do not rely on a family brochure alone.
- Record server slot, PCIe 4.0 x16 availability, NUMA placement and lane-sharing constraints.
- List both network endpoints, desired HDR or Ethernet modes and complete media OPNs.
- Define the rejection or re-approval path if the received suffix or hardware identity differs.
Acceptance and evidence path
- Photograph or record the received OPN and compare it with the approved bill of materials.
- Capture adapter identity, PCIe generation and width, firmware and driver versions.
- Test each intended port with its assigned switch port and media, including error counters and RDMA behavior.
- Run representative traffic, reboot, failover and recovery tests; retain results against the exact hardware identity.
FAQ
What does the SP suffix mean?
The retained page does not say. Obtain current documentation for the exact OPN before assigning a meaning or compatibility claim.
Can the unsuffixed model be accepted as an automatic substitute?
No. Shared high-level specifications are insufficient; substitutions require exact identity evidence and a controlled compatibility review.
Is testing one QSFP56 port enough?
Only if the approved deployment uses one port. A dual-port design should exercise both intended paths, configurations, media and recovery behavior.
Evidence boundary: The page retains only the exact OPN and listed dual-port, rate, PCIe, family and RDMA attributes. It does not define the SP suffix or confirm price, stock, delivery, authorization, certification, warranty, lifecycle, equivalence or measured performance.
Check other NVIDIA network-adapter OPNs, compare data-center network products, review project deployment contexts, and submit an exact-OPN matrix through the buyer guide.
