Dual-Port 10 Gbps SFP+ Adapter
The Intel X520-DA2 adds two 10 Gbps Ethernet ports to a desktop or server through a PCI Express x8 slot. It accepts SFP+ transceivers or direct-attach cables for fiber or copper links. The card targets administrators who need high-throughput networking for storage clusters, virtualization hosts or backup networks.
IEEE 802.3ae and 802.3an limits
Each port runs at up to 10 Gbps under the 10GBASE-R and 10GBASE-T families of standards. Distance and cable type depend entirely on the SFP+ module chosen; the adapter itself does not dictate reach. Link aggregation under 802.3ad can combine both ports for redundancy or extra throughput when the switch supports it.
PCIe x8 slot and SFP+ module check
Verify the host has a free PCI Express x8 or wider slot and that the bracket height matches the chassis. Select SFP+ optics or DAC cables rated for the required distance and fiber type before ordering. The operating system must include or accept drivers for Windows, Linux, VMware ESXi or FreeBSD.

คำถามเกี่ยวกับสินค้านี้
Should I pick a single-port or dual-port 10 Gbps SFP+ card for my server?
This card provides two SFP+ ports, each capable of 10 Gbps, so you can run two independent 10 GbE links or aggregate them for 20 Gbps throughput.
What does the 10 Gbps per port rating mean when the card is installed in a live system?
Each SFP+ port can deliver up to 10 Gbps of Ethernet throughput, limited by the PCIe x8 host slot and the SFP+ transceiver or DAC cable you install.
Will the PCIe x8 interface bottleneck the dual 10 Gbps ports in practice?
A PCIe x8 slot provides ample bandwidth for two 10 GbE ports, so the interface does not cap the 10 Gbps per-port rate under normal loads.
