  • Internal 1394 PortsNone
  • External Ports2 × SFP+ (10Gb fiber or DAC support)
  • 10 Gbps per port for high-speed networking
  • dual SFP+ ports support fiber or DAC connections
  • PCI Express x8 interface fits desktops and servers
  • IEEE 802.3 standards ensure broad compatibility
  • low-profile bracket included for compact builds

Dual-port 10Gb SFP+ network adapter

The Intel X520-DA2 adds two 10 Gbps Ethernet connections through a single PCI Express x8 slot. It targets workstations and servers that need high-throughput links for storage, virtualization or backup traffic.

Low-profile bracket included

A half-height bracket ships in the box so the card fits 2U rackmount chassis or slim desktop cases without extra parts. No transceivers or cables are bundled; SFP+ modules or direct-attach copper must be sourced separately.

Verify slot length and OS driver support

The board requires a physical x8 or longer PCIe slot and draws power from the bus alone. Confirm that your Windows, Linux, VMware ESXi or FreeBSD installation includes the Intel ixgbe driver or can load it from the vendor repository.

Spørgsmål om denne vare

Will the SFP+ modules or direct-attach cables need periodic replacement on the X520-DA2?

The card itself has no moving parts; SFP+ transceivers or DAC cables are separate consumables and should be replaced only if link errors or physical damage appear.

What limits sustained throughput on the X520-DA2 during continuous 10 Gbps traffic?

Each port is rated for up to 10 Gbps and the PCI Express x8 interface provides sufficient bandwidth, so the practical limit is the attached switch or storage device.

How much heat and power does the X520-DA2 generate when running all day?

The adapter is a passive PCIe x8 card with no onboard fan; typical draw is modest and it relies on system airflow for cooling.
