Dual-port 10 GbE SFP+ adapter for servers

The Intel X520-DA2 adds two 10 Gbps Ethernet connections over SFP+ cages, accepting either fibre transceivers or direct-attach copper cables. It targets data-centre hosts running virtualised workloads, high-performance computing clusters or unified storage fabrics that need more I/O bandwidth than 1 GbE links can provide.

Low-profile PCIe 2.0 x8 installation

The card fits a standard PCI Express 2.0 x8 slot and ships with a low-profile bracket for slim chassis. Drivers are supplied by Intel for Windows, Linux, VMware ESXi and FreeBSD. The only common issue is neglecting to order compatible SFP+ modules or DACs separately, as none are included in the box.

PCI Express 2.0 x8 bus interface

The adapter communicates over a PCIe 2.0 x8 link, so the host must provide at least one x8 electrical slot (x16 physical slots wired x8 also work). Systems limited to x4 or x1 electrical lanes will restrict throughput below the dual 10 Gbps line rate.

Preguntas sobre este artículo

How can I confirm the X520-DA2 is operating at 10 Gbps after installation?

Check the link speed in the OS network settings or driver utility; it should show 10 Gbps on each SFP+ port when a compatible module or DAC is connected.

What ships with the X520-DA2 and what must I purchase separately?

The box contains the dual-port adapter and a low-profile bracket; SFP+ transceivers or direct-attach cables are not included and must be bought separately.

Which version of the X520-DA2 should I choose for a PCIe 2.0 x8 slot?

This model uses a PCIe 2.0 x8 interface and fits both full-height and low-profile slots, so it is the correct version for that bus type.
