SMUGDESK

SMUGDESK MCX311A-XCAT ConnectX-3 EN 10G SFP+ PCIe 3.0 x8 Network Card

SKU CH-1KSB-6H1SE

Adds a single 10 GbE SFP+ port via PCIe 3.0 x8 with hardware RDMA, SR-IOV and 9000 MTU jumbo frames for virtualization and storage workloads

  • Single 10G SFP+ port for flexible fiber or copper links
  • PCIe 3.0 x8 bus with 8GT/s bandwidth fits x4, x8 or x16 slots
  • Hardware RDMA and SR-IOV offload cut CPU load under heavy throughput
  • Full and low-profile brackets included for rack or compact chassis
  • Broad OS support covers Windows, Linux, VMware ESXi 6/7/8 and more

Single-Port 10G SFP+ Adapter

The SMUGDESK ConnectX-3 EN adds one 10GbE link through an open SFP+ cage that accepts fibre transceivers, direct-attach copper cables or active optical cables. It plugs into a PCIe 3.0 x8 slot and runs at 8GT/s while remaining compatible with x4, x8 or x16 slots. Both full-height and low-profile brackets are included so the card fits standard rack servers and compact SFF chassis alike.

Virtualisation Hosts and DIY NAS Builders

Hardware RDMA, SR-IOV and VMDq offload let hypervisors move packets with minimal CPU load, making the card a strong fit for VMware ESXi, Proxmox or Hyper-V clusters. Storage workloads benefit from iSCSI and FCoE offload plus 9000 MTU jumbo frames. Desktop users who only need 1GbE or who lack SFP+ cabling infrastructure should look at copper-based alternatives instead.

PCIe 3.0 x8 Bus Width Decides Fit

The card requires an electrical x8 connection to deliver its rated 10GbE throughput; an x4 slot will halve available bandwidth and may bottleneck sustained transfers. Verify that the target motherboard or riser can supply at least x8 electrical lanes before purchasing. The 3.0 signalling rate is fixed, so newer PCIe 4.0 or 5.0 platforms will operate at 3.0 speeds.

Questions about this item

What bandwidth does the PCIe 3.0 x8 interface provide for this 10G SFP+ card?

The PCIe 3.0 x8 bus delivers 8GT/s bandwidth, which is sufficient to saturate the single 10G SFP+ port without bottlenecking throughput.

Which brackets are included for mounting the card in different chassis types?

Both a full-height bracket and a low-profile bracket are supplied, so the card fits standard rack servers and compact SFF small-form-factor cases.

How is the adapter installed, and what driver step is often missed?

Insert the card into any PCIe x4, x8 or x16 slot, attach the appropriate bracket, then install the vendor driver for your OS — Windows, Linux, VMware ESXi 6/7/8, FreeBSD or XenServer — to enable RDMA, SR-IOV and offload features.
