Server-grade 10GbE adapter

The Dell X520-DA2 is a dual-port SFP+ network card built on the Intel 82599ES chipset. It connects through a PCI Express 2.0 x8 slot and delivers two 10Gbps links for virtualization, cloud workloads and high-speed backups. A low-profile bracket is included for compact chassis.

Low power draw and thermal profile

Typical power consumption is rated at 4.9W, keeping heat output modest inside dense server racks. The small 6.6 by 2.7 by 0.7 inch board fits low-profile slots without blocking adjacent cards. Passive cooling relies on chassis airflow rather than an onboard fan.

Bracket and driver support included

The package supplies the adapter and a low-profile bracket for immediate installation in half-height systems. Intel provides drivers for Windows Server 2008 through 2019, Linux distributions such as RHEL, CentOS and Ubuntu, plus VMware ESXi and FreeBSD. No transceivers or cables are bundled.

Questions about this item

How do I install the low-profile bracket on the X520-DA2 and which step is often missed?

Insert the card into a PCI Express 2.0 x8 slot, then attach the included low-profile bracket; the step often missed is securing the bracket screw to the chassis before tightening the card's retention screw.

What maintenance or replacement will the SFP+ ports need over time?

The SFP+ ports accept standard transceivers or DAC twinax cables; only the transceiver modules or cables require replacement if they fail, not the card itself.

What limit appears first when both ports run at 10 Gbps continuously?

Typical power draw is ~4.9 W; sustained line-rate traffic on both ports will hit the PCI Express 2.0 x8 bandwidth ceiling before thermal limits become an issue.
