Dual 100GbE server adapter

The C&N Dual-QSFP28+ 100G Ethernet Network Adapter adds two 100 gigabit per second ports to a server or workstation through a PCIe 4.0 x16 slot. It uses the Intel E810 controller to accelerate NFV, storage, HPC-AI and hybrid cloud workloads. Low-profile and full-height brackets are included for standard and ultra-thin chassis.

Thermals, noise and power draw

The card draws power only from the PCIe slot and has no onboard fan, so it adds no audible noise beyond the host system airflow. Its 275 gram mass and passive heatsink rely on case ventilation to stay within operating limits during typical enterprise traffic.

Sustained load behaviour

Each port sustains 100Gb/s transmit and receive with up to 80 million packets per second TX and 90 million packets per second RX. The controller supports 256 virtual functions and RDMA over iWARP and RoCEv2 for continuous high-throughput storage and compute clusters.

Questions about this item

How do I install the C&N Dual-QSFP28+ adapter in a PCIe 4.0 x16 slot?

Insert the card into a PCIe 4.0 x16 slot; the x16 edge connector runs at 16 GT/s and is backward compatible with PCIe 3.0. Secure the bracket — both low-profile and full-height brackets are included — then attach QSFP28 DAC, optic or AOC cables to the two ports.

What maintenance will the adapter need over time?

No scheduled maintenance is required; keep the QSFP28 ports dust-free with caps when cables are removed and ensure chassis airflow meets the card's thermal needs. Firmware updates for the Intel E810 controller can be applied via the OS driver package when released.

What throughput limit appears first under sustained load?

Each port delivers up to 100 Gb/s TX and RX with 80 Mpps TX and 90 Mpps RX; the PCIe 4.0 x16 host interface provides up to 256 GT/s raw bandwidth, so the first ceiling is the per-port 100 Gb/s line rate.
