  • PCIe 8-lane Gen2 interface provides high bandwidth
  • 1024 virtual NICs per port enable dense virtualisation
  • SFP+ cages accept choice of transceivers

Dual-port 10GbE SFP+ adapter

The Solarflare SF329-9021-R7 is a dual-port 10GbE SFP+ network card built for servers and workstations that need two 10 Gbps links. It installs in an eight-lane PCIe Gen2 slot and uses a low-profile bracket so it fits in slim chassis. Transceivers are not supplied with the card.

Upgrading from single-port or 1GbE links

This card replaces a single-port 10GbE adapter or a pair of 1 GbE NICs when the system needs twice the 10 Gbps bandwidth in the same slot. The jump is worth it when the application can use both ports concurrently for throughput or redundancy. Buyers who only need one 10 Gbps connection or who lack SFP+ cabling will not benefit from the second port.

Sustained load with 1024 vNICs per port

Each port supports up to 1024 virtual NIC interfaces so the adapter can maintain many isolated traffic streams under continuous load. The eight-lane PCIe Gen2 interface provides the bus bandwidth to keep both 10 Gbps links saturated without throttling. Performance scales with the number of active vNICs and the quality of the installed transceivers.

Questions about this item

Does the SF329-9021-R7 need a full-height or low-profile bracket to fit my server?

The card ships with a low-profile bracket for 1U and other slim chassis; a full-height bracket is not included.

What PCIe slot width and generation does the SF329-9021-R7 require for installation?

Install into an x8 PCIe Gen2 slot; the card uses eight lanes and will not negotiate full bandwidth in an x4 or x1 slot.

When should I replace the SFP+ transceivers used with the SF329-9021-R7?

Transceivers are not included; replace them when link errors appear, after a firmware update that changes supported optics, or if you migrate to a different fibre type or distance.
