Intel X520-DA2 10 Gb dual SFP+ PCIe 2.0 x8 network card

SKU CH-ZFGY-G6D2Q MPN X520-DA2

Dual 10 Gbps SFP+ ports on a PCIe 2.0 x8 interface with the Intel 82599ES controller for server networking

  • Dual 10 Gbps SFP+ ports for high-speed server links
  • Intel 82599ES controller delivers consistent throughput
  • PCIe 2.0 x8 interface maximises available bandwidth
  • High-profile bracket fits standard full-height chassis
  • SR-IOV and VMDq support optimises virtualised workloads

Dual-port 10 GbE SFP+ adapter

The Intel X520-DA2 is a dual-port 10 GbE SFP+ network adapter built on the Intel 82599ES controller. It connects through a PCIe 2.0 x8 interface and includes a high-profile bracket for standard server or workstation chassis. Two SFP+ cages accept optical modules or direct-attach cables for 10 Gbps links.

Suits virtualised server and HPC workloads

This card targets environments that need two 10 GbE ports with SR-IOV and VMDq support for virtualised or cloud deployments. Builders who require copper RJ-45 ports, a low-profile bracket, or more than two ports should consider other options.

PCIe 2.0 x8 interface

The adapter operates over a PCIe 2.0 x8 connection, which defines the maximum bus bandwidth available to the dual 10 GbE ports. Verify that the host system provides a compatible PCIe 2.0 x8 or wider slot before purchase.

Questions about this item

How much power does the Intel X520-DA2 draw when both 10 Gbps SFP+ ports are active all day?

The card is powered by the Intel 82599ES controller and uses a PCIe 2.0 x8 interface; typical load power for this generation of dual-port 10 GbE adapters is well within the slot limit, so no auxiliary power connector is required.

What cabling or modules must I already have to use the two SFP+ ports on this adapter?

The package includes only the NIC with a high-profile bracket; you must supply your own SFP+ transceivers or direct-attach copper cables that match the switch or server port type you are connecting to.

Will the PCIe 2.0 x8 interface on the X520-DA2 work in an older server that only has PCIe 1.1 or 2.0 slots?

Yes, the card is backward compatible with PCIe 1.1 and 2.0 slots; it will negotiate the highest link speed the slot supports, though throughput scales with the link width and generation available.
