SMUGDESK ConnectX-5 EN Dual-Port 100GbE QSFP28 NIC PCIe 3.0 x16 Full Height Bracket

SKU CH-B4X2-KYWT1

Dual QSFP28 ports deliver 10, 25, 40, 50 or 100GbE speeds over PCIe 3.0 x16 with hardware offload, RDMA and SR-IOV for server clusters

  • Dual QSFP28 ports run 10 to 100GbE for flexible high-speed links
  • PCIe 3.0 x16 bus supplies abundant bandwidth for data-intensive workloads
  • Hardware offload with RoCE RDMA and SR-IOV cuts host CPU load
  • Full-height bracket fits standard rack server chassis out of the box
  • RoHS R6 certified for stable long-term operation in cloud and HPC clusters

Dual QSFP28 100GbE adapter for servers

The SMUGDESK ConnectX-5 EN is a dual-port network interface card built for data-centre and high-performance computing clusters. It fits a standard PCIe 3.0 x16 slot and ships with a full-height bracket for regular rack chassis. Buyers needing a single-port or 10GbE-only card should look elsewhere.

PCIe 3.0 x16 bandwidth ceiling

The card runs on a PCIe 3.0 x16 link, which caps total throughput at the bus limit even though each QSFP28 port can signal at 10, 25, 40, 50 or 100GbE. Aggregated line-rate traffic on both ports can saturate the host interface, so sustained 100GbE bidirectional flows may be constrained by the slot.

Full-height bracket fits standard racks

Installation is a direct mechanical fit into any server chassis that accepts a full-height PCIe card; no low-profile bracket is supplied. The dual QSFP28 cages accept both direct-attach copper and optical modules, but mismatched transceiver speeds or unsupported cable lengths are the most common cause of link failures.

Questions about this item

Should I pick the 10GbE, 25GbE, 40GbE, 50GbE or 100GbE speed for my link?

Each QSFP28 port auto-negotiates to 10, 25, 40, 50 or 100GbE based on the inserted transceiver or DAC, so choose the module that matches your switch and cable budget.

What does the 100GbE rating mean when the card is installed in a server?

The dual-port adapter can deliver up to 100GbE per port using QSFP28 optics or copper, with full hardware offload and RDMA to keep host CPU utilisation low at line rate.

How does the PCIe 3.0 x16 interface affect real-world throughput?

The PCIe 3.0 x16 bus provides the upstream bandwidth needed for dual 100GbE traffic, while SR-IOV virtualisation lets multiple VMs share the ports without bottlenecks.
