  • Product class10G,Dual SFP
  • Dual 10 GbE ports for high-bandwidth server links
  • PCI Express 3.0 x8 host interface avoids bus bottlenecks
  • SFP+ cages accept twinax or fibre for flexible cabling
  • Intel X710 controller delivers up to 80 Gb/s bi-directional throughput
  • Converged LAN and SAN support simplifies data-centre networking

Dual 10G SFP+ adapter for servers

The Intel X710DA2 is a dual-port 10GBase-X network card built on the Intel X710 controller. It installs in a PCI Express 3.0 x8 slot and presents two SFP+ cages for twinaxial or optical modules. The adapter targets data-centre workloads that need converged LAN and SAN traffic on a single fabric.

Replaces single-port or 1 Gb links

Moving from a single 10G port or a 1 Gb NIC doubles immediate bandwidth and adds link redundancy without changing cabling. The jump is worth it when virtualisation hosts or storage clusters saturate existing links and the quad-port 80 Gb/s ceiling of the X710 family is not yet required.

Fits PCIe 3.0 x8 slots, frees I/O lanes

The card occupies one x8 slot and leaves remaining lanes for storage controllers or additional NICs. Two SFP+ cages let you choose direct-attach copper for short runs or fibre for longer distances, keeping rack cabling flexible while the host handles up to 40 Gb/s per direction.

Questions about this item

Does the X710-DA2 need a PCI Express 3.0 x8 slot to install?

Yes, the host interface is PCI Express 3.0 x8, so the motherboard must provide an x8 electrical connection.

Which step do installers often miss when fitting the SFP+ modules?

Insert each SFP+ transceiver until it clicks, then lock the bail latch before connecting any twinaxial cables.

When should the SFP+ transceivers or twinaxial cables be replaced?

Replace them if link errors appear, cables show physical damage, or a speed upgrade requires different media.
