BoYata 200GbE Smart NIC Dual QSFP56 PCIe 4.0 x16 network connector

SKU CH-CSH6-CQ9NW

A 200GbE smart NIC with dual QSFP56 ports, PCIe 4.0 x16 and Mellanox ConnectX-6 VPI controller delivering sub .6usec latency for data-centre workloads

  • Low CPU load with sub .6 µs latency
  • Dual QSFP56 ports at 10/25/40/50/100 GbE plus HDR
  • Single-port 200 Gb/s Ethernet on PCIe 4.0 x16
  • SR-IOV virtualization shares I/O across multiple VMs
  • Broad OS support from Windows and Linux to ESXi and FreeBSD

Dual QSFP56 200GbE Smart NIC for data centres

This network adapter targets data-centre operators and HPC clusters that need 200Gb/s Ethernet or HDR InfiniBand connectivity. The Mellanox ConnectX-6 VPI controller delivers high throughput with sub .6usec latency and low CPU overhead. Dual QSFP56 cages support a wide range of link speeds from 10GbE up to 100GbE per port. It is not suited for desktop PCs or small-office routers that lack PCIe 4.0 x16 slots and matching cabling.

Capacity headroom across 10GbE to 200Gb/s links

Each QSFP56 port negotiates 10GbE, 25GbE, 40GbE, 50GbE or 100GbE Ethernet, plus HDR InfiniBand, giving flexible headroom for mixed-speed fabrics. A single port can run at the full 200Gb/s Ethernet rate when cabled accordingly. The PCIe 4.0 x16 interface at 16.0GT/s supplies enough bus bandwidth to sustain line-rate traffic on both ports simultaneously. Workloads that exceed 200Gb/s aggregate throughput or require more than two physical ports will need additional adapters.

PCIe 4.0 x16 slot requirement decides fit

The card needs a full-length PCIe 4.0 x16 slot (also compatible with 1.1, 2.0 and 3.0 at reduced bandwidth) to deliver its rated performance. Systems limited to x8 electrical lanes or older PCIe generations cannot reach the advertised 200Gb/s ceiling. Buyers must verify motherboard or riser support for x16 electrical width before purchase.

Questions about this item

Will the PCIe 4.0 x16 slot run at full speed on my older motherboard that only supports PCIe 3.0?

The card is compatible with PCIe 2.0, 3.0 and 4.0. In a PCIe 3.0 x16 slot it will operate at 3.0 speeds, reducing the theoretical ceiling below the 200Gb/s maximum.

How can I verify the ConnectX-6 MT2890 controller is delivering the advertised sub 0.6usec latency after installation?

Use DPDK testpmd or ib_write_lat with RoCE v2 on a quiet 100GbE or 200GbE link; the round-trip time reported by the tool should sit below 0.6 microseconds.

Does the dual QSFP56 package include any transceivers or cables, or must I source 100GbE or 200GbE optics separately?

Only the NIC with two QSFP56 cages is supplied. You must purchase compatible QSFP56 transceivers or direct-attach cables for 10, 25, 40, 50, 100 or 200GbE links.
