ConnectX-6 Dx 100 GbE dual-port adapter

This NVIDIA ConnectX-6 Dx network card delivers up to 100 gigabits per second over two QSFP56 ports. It installs in a PCIe 4.0 x16 slot and supports copper or optical transceivers. The board operates from 0 to 55 degrees Celsius and meets CB, cTUVus, CE, FCC, VCCI, ICES and RCM regulatory marks.

Built for high-throughput data-centre workloads

Suits servers that need 100 GbE connectivity with hardware offloads for IPsec, TLS and overlay tunnels. The programmable pipeline accelerates virtual switching and packet processing. Not for desktop PCs lacking a full-length x16 slot, nor for environments that require only 10 or 25 GbE links.

Dual QSFP56 ports at 100 GbE each

Two ports provide up to 200 Gb/s aggregate bandwidth and a message rate of 215 Mpps with sub 0.8 microsecond latency. Multi-Host support and QoS allow multiple hosts or partitions to share the adapter. Copper or optical modules can be mixed per link speed from 1 to 100 Gb/s.

Highlights

  • 100 Gb/s per port with dual QSFP56 connectors
  • Sub 0.8 µs latency for real-time workloads
  • 215 Mpps message rate for high packet throughput
  • PCIe 4.0 x16 interface delivers 200 Gb/s total bandwidth

Questions about this item

Will the MCX623106AS-CDAT run in my older PCIe 3.0 server slot?

The card uses a PCIe 4.0 x16 interface and will operate in a PCIe 3.0 x16 slot at PCIe 3.0 speeds, reducing the maximum available bandwidth from the 4.0 rate.

How can I verify the dual QSFP56 ports are linked at 100 Gb/s after installation?

Check the adapter status in the OS or management utility; each port should report a 100 Gb/s Ethernet link with the negotiated protocol such as 100GBASE-SR4 or 100GBASE-CR4.

Does the MCX623106AS-CDAT ship with QSFP56 transceivers or DAC cables, or must I buy them separately?

The card is supplied as the plug-in adapter only; compatible QSFP56 optical modules or copper DAC cables for the dual ports must be purchased separately.
