The SFN5122F dual-port SFP+ 10 Gbit Ethernet server adapter is said to provide the industry’s lowest power and lowest latency. The card delivers 40-Gbit/s aggregate bandwidth using 5-GT/s PCIe 2.0.

The board requires only 5 W typ for each port and can deliver sub-5µs UDP/TCP application latencies. It works with Windows, Red Hat and RHEL Linux, Solaris, VMware, Citrix XenServer, and Novell operating systems and provides a rich set of stateless offloads including: iSCSI, RSS, TCP/IP and UDP, LSO/TSO, and LRO.
