Dual-port 10Gb Ethernet adapter
The DELL X520-DA2 adds two RJ-45 ports running at up to 10 Gbps each through a PCI Express x8 slot. It targets administrators upgrading desktop or server systems to 10Gb wired networking without changing cabling infrastructure. The low-profile bracket fits compact chassis while the Intel controller supports Windows, Linux, VMware ESXi and FreeBSD.
IEEE 802.3an practical limits
The card implements IEEE 802.3an for 10GBASE-T over copper twisted pair, which requires Category 6a or better cabling to reach the full 10 Gbps per port. Cable runs must stay within the 100-metre channel limit defined by the standard and signal quality degrades sharply with poorer cable categories or excessive connector loss.
Verify slot width and bracket clearance
Confirm the host system has a free PCI Express x8 or wider slot; an x4 physical slot will not provide the required lane count even if the card fits mechanically. Ensure the low-profile bracket matches the chassis slot height and that the operating system in use appears in the supported list before ordering.

Jautājumi par šo preci
Should I pick the dual-port 10 Gbps model or a single-port alternative?
This card provides two RJ-45 ports, each capable of up to 10 Gbps, so you get twice the throughput in one PCIe slot.
Will I actually see 10 Gbps throughput in my desktop?
Real-world speeds reach close to 10 Gbps per port when the CPU, PCIe x8 lane width and cabling all support the rate.
Does the PCIe x8 interface limit the total bandwidth?
The x8 slot supplies enough lanes for both ports to run at 10 Gbps simultaneously without a bottleneck.
