NVIDIA ConnectX-8 C8180 800Gbs XDR IB 2x400GbE network card 900-9X81E-00EX-ST0

SKU CH-MM02-ZKX5F MPN 900-9X81E-00EX-ST0

Half-height network card delivering 800 Gb/s InfiniBand XDR or dual 400 Gb/s Ethernet via a single OSFP cage on PCIe 6 x16

  • Rated speedInfiniBand: 800Gbs XDR IB (Default) Ethernet: 2 × 400GbE
  • Interface typePCI-Express
  • 800 Gbs XDR InfiniBand bandwidth for high-performance compute clusters
  • Dual 400 GbE Ethernet ports for flexible data-centre networking
  • PCIe 6 x16 interface delivers maximum host throughput
  • Half-height half-length form factor fits dense server chassis
  • Single OSFP cage simplifies cabling with one transceiver slot

ConnectX-8 C8180 800Gb/s SuperNIC

The NVIDIA ConnectX-8 C8180 is a half-height half-length network interface card built for high-performance compute clusters and AI infrastructure. It targets system integrators and data-centre operators who need a single adapter that can run at native InfiniBand XDR speeds or split into dual 400GbE links.

PCIe 6 x16 interface and OSFP cage

The card plugs into a PCIe 6 x16 slot and presents a single OSFP cage that carries either 800Gb/s InfiniBand XDR or two independent 400GbE channels. This interface and cage combination is the decisive compatibility factor; the host must provide a PCIe 6 x16 socket and the correct OSFP optics or direct-attach cables for the chosen protocol.

800Gb/s InfiniBand or dual 400GbE capacity

At 800Gb/s the adapter delivers the bandwidth demanded by large-scale GPU interconnect and storage fabrics while the dual 400GbE mode serves high-density Ethernet leaf-spine tiers. The single OSFP port limits aggregate throughput to 800Gb/s, so environments requiring more than two 400GbE links or additional InfiniBand ports will need multiple cards.

Questions about this item

What throughput will I see inside the server when the card runs at 800 Gbs XDR InfiniBand?

The adapter delivers up to 800 Gbs over InfiniBand XDR or two 400 GbE lanes, limited by the PCIe 6 x16 host bus and the single OSFP cage.

Which PCIe generation and lane width does the board require for full bandwidth?

It needs a PCIe 6 x16 slot; the x16 electrical interface matches the physical connector so no lane bifurcation is required.

What bracket height and slot length does the HHHL form factor need?

Half-height, half-length bracket fits a standard low-profile PCIe x16 slot without a full-height bracket.
