MCX516A-CCAT is a NVIDIA/Mellanox ConnectX-5 dual port 100GbE QSFP28 PCIe 3.0 network Adapter. Offload features — RDMA, SR-IOV, tunnel offload — are the reason to choose one adapter over another, and they are firmware-gated. Tell us what you need offloaded and we will confirm the feature is enabled on this part.

What you get ordering this from us
Ordered by part number
MCX516A-CCAT is what is quoted and MCX516A-CCAT is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
- Is MCX516A-CCAT genuine and is the warranty intact?
- Yes — new and sealed, with the NVIDIA/Mellanox warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will MCX516A-CCAT work in my server?
- Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.
- Do you accept purchase orders and quote at volume?
- Yes — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.
