Dual-Port 10GbE SFP+ Adapter

The Dell X520-DA2 adds two 10Gbps SFP+ ports to a desktop or server through a PCI Express 2.0 x8 slot. It supports fiber or direct-attach copper cabling and works with Windows, Linux, VMware ESXi and FreeBSD. The low-profile bracket is included for compact chassis installations.

Fits x8 Slots, Not x1

This card suits administrators upgrading rackmount or tower servers that have an open x8 or larger PCIe slot and need dual 10GbE links. Builders with only x1 or x4 slots cannot use the adapter at full bandwidth, and systems lacking SFP+ transceivers or DAC cables will need to source those separately.

Two Ports at Line Rate

Each SFP+ port delivers up to 10Gbps, so the adapter comfortably handles dual 10GbE uplinks, iSCSI storage traffic or high-throughput virtualisation clusters. The PCIe 2.0 x8 interface provides enough bandwidth for both ports simultaneously, but total throughput cannot exceed the host bus limit.

Highlights

Questions about this item

Do I need an available PCI Express 2.0 x8 slot or wider on my motherboard for this adapter?

Yes, the card installs in a PCI Express 2.0 x8 or higher slot in a desktop or server system.

Will my existing SFP+ direct-attach cables or 10 Gb fibre modules work with the two ports on this card?

The two SFP+ ports accept standard 10 Gb fibre transceivers or DAC cables you already use.

How can I confirm each port is running at 10 Gbps after I install the adapter?

Check the link speed in your OS network settings or run a throughput test; both ports should report 10 Gbps when connected.
