Dell Solarflare S7120 10GbE dual-port NIC

The Dell Solarflare S7120 4C7RT adds two 10 Gbps SFP+ connections through a PCIe 3.0 x8 slot. It targets data-centre workloads, high-frequency trading platforms and virtualisation clusters that demand predictable throughput. The low-profile form factor fits dense chassis while an optional full-height bracket supports standard racks.

Sustained throughput on the SFC9020 controller

The Solarflare SFC9020 chipset maintains line-rate 10 Gbps per port under continuous load rather than only in short bursts. SR-IOV and DPDK support offload packet processing from the host CPU, keeping latency stable during extended traffic runs. Low power draw helps the card stay within thermal limits inside packed server shelves.

Low-profile bracket and SFP+ module choices

Installation starts by selecting the bracket that matches the chassis height, then seating the x8 card firmly in the slot. The most common issue is forgetting to order compatible SFP+ transceivers or direct-attach cables separately, leaving the ports dark. Driver packages for major Linux distributions and Windows Server are available from the vendor support site.

Vragen over dit artikel

How much power does the Solarflare S7120 draw when both 10GbE ports run at full speed all day?

The SFC9020 controller is designed for low power consumption in data-centre workloads; exact wattage varies with cable type and link utilisation, so plan for typical 10GbE SFP+ power envelopes in your chassis.

Which SFP+ transceivers and cables must I already own to use the dual 10GbE ports?

Any standard SFP+ module — short-reach, long-reach or direct-attach copper — will plug into the two ports; the card itself ships without transceivers.

Will the PCIe 3.0 x8 interface work in an older server that only has PCIe 2.0 x8 slots?

Yes, the card is backward compatible and will negotiate down to PCIe 2.0 x8, halving the theoretical slot bandwidth while both 10GbE ports remain fully functional.
