Green circuit board with silver PCIe x8 edge connector and single SFP+ cage, passive silver heatsink on black controller chip

SMUGDESK

SMUGDESK Intel 82599 X520-DA1 10G SFP+ Network Card

SKU CH-9MWJ-K604P

Adds a single SFP+ 10 Gbps fiber link to a server via PCIe 3.0 x8 using the Intel 82599 controller with SR-IOV, VMDq, 9.5 KB jumbo frames and hardware TCP offload

  • 10 Gbps full-duplex fiber with Intel 82599 controller
  • PCIe 3.0 x8 bandwidth fits standard server expansion slots
  • SR-IOV and VMDq virtualization offload cuts CPU load
  • 5 KB jumbo frames plus TCP offload for high throughput
  • Passive heatsink rated for 24/7 continuous server operation

Single-Port 10G SFP+ Server NIC

This SMUGDESK network card uses the Intel 82599 controller on the X520-DA1 architecture to deliver a single 10Gbps fiber link. It targets administrators building storage clusters, virtualization hosts or high-speed soft routers that need reliable 10 Gigabit Ethernet connectivity.

PCIe 3.0 X8 With Passive Heatsink

The card installs in a standard PCIe 3.0 X8 slot and is backward compatible with X16 sockets found on enterprise server motherboards. A passive heatsink enables 24/7 operation without active cooling, while the modular SFP+ cage accepts multimode or singlemode transceivers for flexible fiber reach.

Verify Slot, OS And Transceiver Needs

Confirm your chassis provides an open PCIe X8 or X16 slot with adequate bracket space for the low-profile bracket. Ensure the target operating system — Windows Server, Linux, FreeBSD or VMware ESXi — is supported, and source compatible 10G SFP+ optics separately as the card ships without transceivers.

Questions about this item

What PCIe generation and lane width does this Intel 82599 X520-DA1 card use, and what throughput does that cap at?

The card runs on a PCIe 3.0 x8 link, giving up to 8 GT/s per lane for a practical ceiling near 10 Gbps full-duplex.

What slot length and bracket height does the X520-DA1 need to fit in a server chassis?

It requires a standard PCIe x8 or x16 slot with a full-height bracket; the passive heatsink fits typical 1U or 2U server clearance.

How is the SFP+ transceiver installed, and what step do builders often miss?

Insert the SFP+ module until it clicks, then lock the bale-clasp before cabling; many forget the clasp and get intermittent link.
