Dual-port 10Gbps SFP+ server adapter

The Intel X520-DA2 is a dual-port network interface card built for servers and workstations that need 10 gigabit Ethernet connectivity. It uses the Intel 82599ES controller and connects through a PCI Express 2.0 x8 slot, compatible with x8 and x16 slots. The card targets IT professionals adding high-speed links to rackmount or tower systems.

Two SFP+ cages for fibre or direct attach

Two SFP+ cages accept 10G multi-mode modules, single-mode modules or direct-attach copper cables, letting you choose the reach and media type per link. Each port runs at 10Gbps line rate under IEEE 802.3 10BASE-SR and 10BASE-LR standards. The x8 5GT/s bus provides enough bandwidth for both ports simultaneously without saturation.

Low-profile bracket fits dense chassis

A low-profile bracket allows installation in 1U and 2U rackmount servers where full-height cards do not fit. The SFP+ cages face the rear bulkhead for clean cable routing in hot-aisle or cold-aisle layouts. No onboard transceivers are included, so you supply the optics or DACs that match your switch ports and distance requirements.

Questions sur cet article

Will this card run at 10 Gbps in my PCIe 2.0 x8 slot?

The card uses a PCIe 2.0 x8 electrical interface and is compatible with x8 or x16 slots, so it will deliver the full 10 Gbps rate in a PCIe 2.0 x8 slot.

How can I verify both SFP+ ports are linked at 10 Gbps after installation?

Check the adapter LEDs or the OS network status; each port should show a 10 Gbps link when a supported SFP+ module and cable are connected.

Does the box include SFP+ transceivers or cables, or must I buy them separately?

The adapter ships without transceivers or cables; you must purchase compatible SFP+ modules or direct-attach cables separately.
