PCIe 4.0 x16 network adapter with dual 100 Gigabit QSFP56 ports delivering 200 Gbps throughput

  • PCI Express 4.0 x16 interface delivers 200 Gbps total bandwidth
  • Dual 100 Gigabit QSFP56 ports provide 100GbE connectivity
  • Crypto-disabled design suits environments with export restrictions
  • Plug-in card form factor installs in standard PCIe slots
  • Network adapter purpose-built for high-speed data links

NVIDIA ConnectX-6 Dx adapter

This NVIDIA ConnectX-6 Dx network adapter uses a PCIe 4.0 x16 interface and provides two 100 Gigabit QSFP56 ports. It is built for servers and workstations that need high-throughput Ethernet connectivity. The card is supplied new and includes no cryptographic acceleration.

PCIe 4.0 x16 host interface

The card installs in a PCI Express 4.0 x16 slot and delivers an aggregate data rate of 200 Gbps across both ports. Each port runs the 100GbE protocol so the link speed is fixed at 100 Gbps per QSFP56 transceiver. Verify that the host platform has a compatible x16 slot before ordering.

Suited for dual-port 100GbE links

This adapter suits deployments that require two 100 Gbps Ethernet links from a single x16 slot. It is not for buyers who need onboard encryption offload, fibre-channel support, or a single-port or lower-speed network interface.

Questions about this item

What does the 200 Gbps total throughput mean once the adapter is installed in a server?

The card delivers up to 200 Gbps of combined network bandwidth across its two 100 Gbps ports, so a single host can sustain line-rate traffic on both links simultaneously.

How does the PCI Express 4.0 x16 interface affect real-world performance?

The PCIe 4.0 x16 bus supplies enough host bandwidth to keep both 100 Gigabit QSFP56 ports running at full speed without a bottleneck.

What physical slot and bracket space does this plug-in card require?

It needs a full-height PCI Express x16 slot and occupies one rear bracket opening for the dual QSFP56 cage.
