NVIDIA Mellanox ConnectX-4 EN MCX415A-CCAT
Single-port QSFP28 100GbE PCIe adapter. Confirm exact product label and revision before applying specifications.
IDENTIFICATION: Confirm manufacturer PID, hardware revision, device ID or module suffix. Nominal standards/link rates are not measurements of payload performance.
Exact specifications and compatibility
| Dedicated subcategory | 10 Gigabit and server adapters |
|---|---|
| Exact product/model | NVIDIA Mellanox ConnectX-4 EN MCX415A-CCAT |
| Bus, ports and physical interface | PCIe 3.0 x16; one QSFP28 cage; qualified media and airflow required. |
| PHY, radio or protocol | ConnectX-4 EN Ethernet controller; supported link modes include 100GbE and model/firmware-validated lower rates. |
| Nominal rate (not measured) | Up to 100Gb/s nominal port PHY; host PCIe/traffic limits mean this is not a measured payload result. |
| Measured throughput | No measured benchmark is claimed for a physical specimen. A valid result must record host/peer, link partner, media/cable, driver/firmware, traffic pattern, test tool and duration. |
| Drivers, OS and firmware | NVIDIA documents Linux mlx5_core and OFED support by release; firmware image must match adapter PSID. |
| Compatibility | Requires PCIe x16 electrical slot, QSFP28 media supported by the exact board, matching peer rate and sufficient cooling. |
| Variant warning | MCX415A-CCAT is single-port ConnectX-4 EN; do not confuse with VPI, Lx, dual-port or different PSID variants. Check label/PSID before flashing. |
