Dual 10Gbps SFP+ server adapter

The Intel X520-DA2 adds two 10Gbps SFP+ ports through a PCIe 2.0 x8 slot. It is built for servers and workstations that need high-throughput wired links for virtualization, storage or high-performance computing clusters. Driver support covers Windows, Linux, VMware ESXi and FreeBSD.

Low-profile build with SFP+ flexibility

The card measures 6.6 in by 2.7 in by 0.7 in and weighs 0.5 lb, and a low-profile bracket is included for shallow chassis. Two SFP+ cages let you choose copper or fibre transceivers to match the link distance and cabling already in place. IEEE 802.1Q, 802.1p, 802.3ad, 802.1ae and 802.1as support handles VLANs, link aggregation and time-sensitive traffic.

Replaces single-port or 1GbE NICs

Moving from a single 10GbE port or from gigabit adapters doubles available bandwidth and adds redundancy without changing the server board. The jump is worth it when workloads saturate existing links or when converged LAN and SAN traffic need guaranteed QoS. Buyers who need more than two ports or a newer PCIe generation should look elsewhere.

Questions about this item

What throughput does the PCIe 2.0 x8 interface cap at for this adapter?

The PCIe 2.0 x8 slot runs at 5.0 GT/s and provides enough bandwidth for both 10Gbps SFP+ ports to operate at line rate.

What physical space and bracket does the card need to fit?

The board measures 6.6 in × 2.7 in × 0.7 in and ships with a low-profile bracket for slim chassis.

How is the X520-DA2 installed, and what step is often missed?

Seat the card in a PCIe 2.0 x8 slot, attach the low-profile bracket if required, insert SFP+ transceivers, then install the Intel driver for Windows, Linux, ESXi or FreeBSD.
