NVIDIA ConnectX-8 C8180 800 Gbit/s network card 900-9X81E-00EX-DT0

SKU CH-4MHC-00H63 MPN 900-9X81E-00EX-DT0

Delivers 800 Gbit/s connectivity via PCIe 6.0 x16 with an OSFP cage for high-performance networking

  • PCIe 6.0 x16 interface enables smooth high-speed data transfer
  • 800 Gbit/s throughput maximises performance for critical workloads
  • Single OSFP cage supports 800G XDR InfiniBand or dual 400GbE operation
  • Crypto acceleration built in for secure processing
  • Half-height half-length form factor fits dense server configurations

800 Gbit/s SuperNIC for HPC clusters

The NVIDIA ConnectX-8 C8180 is a new half-height network card built for 800 Gbit/s InfiniBand XDR or dual 400 GbE connectivity. It plugs into a PCIe 6.0 x16 slot and includes a single OSFP cage plus a downstream x16 PCIe extension option. Hardware crypto acceleration is integrated for secure data movement.

Suited for high-throughput compute nodes

This card targets servers that need maximum fabric bandwidth for AI training, simulation or storage clusters. Buyers who require multi-port redundancy or lower-speed Ethernet links should look elsewhere. Builds limited to PCIe 5.0 or earlier slots cannot use the full 6.0 x16 throughput.

PCIe 6.0 x16 interface with downstream extension

The card connects through a PCI Express 6.0 x16 interface and offers an optional x16 downstream port for chaining additional devices. This topology decision determines whether the adapter fits the target server backplane and cabling plan.
