NVIDIA ConnectX-7 200 Gb/s Adapter
The NVIDIA MCX75310AAS-HEAT is a single-port ConnectX-7 host channel adapter built for high-performance computing and AI clusters. It delivers 200 Gb/s Ethernet and NDR200 InfiniBand throughput over a PCIe 5.0 x16 interface in a half-height, half-length form factor. The card targets data-centre builders who need ultra-low latency and In-Network Computing acceleration for demanding workloads.
Thermals, Noise and Power Draw
Operational temperature range spans 0 °C to 55 °C with humidity tolerance of 10 % to 85 % relative humidity. Non-operational limits extend to -40 °C and 70 °C at up to 90 % humidity. The passive HHHL design relies on chassis airflow, so acoustic output and power consumption depend entirely on the server cooling solution deployed.
Upgrade Path and Compatibility
This adapter replaces earlier HDR or EDR InfiniBand cards when clusters move to NDR200 or 200 Gb/s Ethernet speeds. The jump is worth it for workloads that can exploit PCIe 5.0 bandwidth, collective acceleration engines and programmable datapath features. Buyers who need dual-port density or QSFP connectors should evaluate other ConnectX-7 SKUs.

Fragen zu diesem Artikel
How is the MCX75310AAS-HEAT installed in a server and which step is commonly missed?
Insert the half-height half-length card into a PCIe 5.0 x16 slot, secure the HHHL bracket, then plug an OSFP transceiver into the single port; the step often missed is confirming the motherboard BIOS enables Gen 5.0 x16 link width so the SERDES run at 32 GT/s.
What maintenance or replacement will this ConnectX-7 card need over its service life?
The card itself has no moving parts; plan to replace the OSFP optical modules if link errors rise, and clean the OSFP connector ferrule with a lint-free swab whenever modules are swapped.
What limit appears first when the adapter runs sustained 200 Gb/s traffic?
The operational temperature ceiling of 55 °C is the first hard limit; if chassis airflow cannot keep the card below that, the ASIC will throttle to protect itself.
