  • Dual 100 GbE ports deliver massive throughput
  • PCIe 4.0 x16 interface provides 16 GT/s bandwidth
  • Mellanox ConnectX-5 Ex controller enables RDMA and SR-IOV
  • Broad OS support covers Windows Server 2016 through 2022
  • Low-profile and full-height brackets fit diverse chassis

100GbE Dual-Port QSFP28 Adapter

This PCIe 4.0 x16 network card is built on the Mellanox ConnectX-5 Ex controller and delivers two 100GbE ports for high-throughput server and storage workloads. It targets data-centre engineers and HPC administrators who need low-latency RDMA and NVMe-oF connectivity in standard or low-profile chassis.

Suits RDMA and storage clusters.

The adapter supports PXE, DPDK, iSCSI, SR-IOV, IEEE 1588 and NC-SI across Windows 10/11, Windows Server 2016/2019/2022, Deepin 15.11/20/20.6/20.9, OpenKylin 0.7.5, MikroTik and Kuai route. Buyers who need only a single 100GbE link or who lack a PCIe 4.0 x16 slot should consider a different form factor.

PCIe 4.0 x16 dual-port 100G QSFP28 interface

The single specification that decides fit is the PCIe 4.0 x16 electrical interface combined with two QSFP28 cages; the card requires a full x16 slot and compatible cabling or transceivers to operate at the rated 100GbE per port.

Questions about this item

How do I install the dual QSFP28 adapter in a PCIe 4.0 x16 slot and which bracket do I use?

Insert the card into a PCIe 4.0 x16 slot, then attach either the low-profile or full-height bracket depending on your chassis height before securing the screw.

What maintenance will the ConnectX-5 Ex based adapter need over time?

Keep the heatsink fins clear of dust and verify driver updates on Windows 10, 11, Server 2016, 2019, 2022, Deepin 15.11, 20, 20.6, 20.9 or OpenKylin 0.7.5.

What limit appears first when both 100 GbE ports run sustained traffic?

The PCIe 4.0 x16 interface caps total throughput at 16 GT/s per lane, which becomes the bottleneck before the dual QSFP28 ports saturate.
