Green PCB network card with black heatsink, dual SFP+ ports and two metal brackets

SMUGDESK

SMUGDESK ST7286-10GB Dual Port 10G SFP+ Network Card

SKU CH-JCQG-32MHF

Dual-port 10G SFP+ adapter with Mellanox ConnectX-3 controller, PCIe 3.0 x8, hardware offload, RoCE v2 RDMA, SR-IOV virtualization and dual brackets for server networking

  • Dual SFP+ ports deliver 10 Gbps links with 1 Gbps fallback
  • PCIe 3.0 x8 at 8.0 GT/s fits x8 and x16 slots
  • Hardware offload cuts CPU load on checksums, LACP, VLAN and tunnels
  • RoCE v2 RDMA with 127 VFs enables low-latency VM passthrough
  • Full-height and low-profile brackets included for 24/7 server operation

Dual-port 10G SFP+ server adapter

The SMUGDESK ST7286-10GB adds two independent 10GbE connections to a server or workstation through a PCIe 3.0 x8 slot. It uses the Mellanox ConnectX-3 EN controller and accepts SFP+ direct-attach copper or fibre modules for flexible link distances. The card includes both full-height and low-profile brackets for 2U chassis compatibility.

Sustained-load behaviour with hardware offload

Full hardware offload handles TCP/UDP/IP checksums, LACP aggregation, 802.1Q VLAN tagging and VXLAN/NVGRE tunnelling without burdening the host CPU. RoCE v2 RDMA delivers microsecond latency for cluster workloads while SR-IOV supports up to 127 virtual functions for dense virtualisation. A passive heatsink maintains stable temperatures during continuous 24/7 operation.

PCIe 3.0 x8 host interface requirement

The adapter needs an available PCIe 3.0 x8 slot running at 8.0GT/s per lane, though it will fall back to PCIe 2.0 or 1.1 x8 and x16 slots. Buyers whose motherboards lack an x8 electrical connection cannot use this card at its rated performance. Broad OS support covers Windows Server 2008 through 2019, Windows 10 and 11, major Linux distributions, VMware ESXi 5.x to 6.x, FreeBSD and XenServer.

Questions about this item

How much power does the ConnectX-3 controller draw when the card runs 24/7?

The card uses a passive black heatsink designed for stable 24/7 continuous operation without active cooling.

Which PCIe slot width and generation must the motherboard provide for full 10 Gbps performance?

A PCIe 3.0 x8 slot at 8.0 GT/s per lane delivers full speed; the card also works in PCIe 2.0 or 1.1 x8 or x16 slots at reduced bandwidth.

Can the adapter operate in a server that still uses Windows Server 2008 or VMware ESXi 5.x?

Yes, drivers are available for Windows Server 2008 through 2019 and for VMware ESXi 5.x through 6.x alongside current Linux and Windows 10/11 releases.
