Solarflare SFN5151T Single-Port 10GBASE-T Performant Server Adapter

combines excellent performance and exceptional 10GbE value for data center, enterprise, SMB, and high-performance computing.


With triple-speed 10GBASE-T, the SFN5151T supports asymmetric upgrades. Because 10GBASE-T auto negotiates with 1000BASE-T and 100BASE-TX, servers can be upgraded asynchronously with switches at the other end of the wire. Equipped to handle application loads of the latest multi-core processors, the SFN5151T also delivers unmatched power efficiency for the consolidation and deployment of high-density servers. The SFN5151T supports data networking with concurrent support of iSCSI and NAS traffic – while providing cost effective, power-efficient and high-performance network I/O.

Application Performance Leadership

The SFN5151T has the industry’s lowest latency along with full 20 Gbps bidirectional line-rate performance. Featuring a rich set of stateless offloads, it provides efficient acceleration of the most demanding network protocol tasks.

Proven Powerful Technology

Based on standards-compliant, robust, power-efficient 10GbE controller and 10GBASE-T PHY technology currently shipping in OEM servers and switches, the SFN5151T enables high-performance, cost-effective solutions for next-generation applications.

Scalable, Hardware-Assisted Virtualization

The SFN5151T is designed to optimize virtualized application performance and maximize the use of network resources. With 10x the number of vNICs and virtual PCIe functions than the competition, I/O performance scales as the number of CPU cores and virtual machines increase resulting in enhanced application performance supporting more applications per physical server.

The SFN5151T accelerates guest applications in leading hypervisors, supporting NetQueue and VMQ in VMware and Hyper-V, and SR-IOV in KVM and XenServer. SFN5151T relieves network I/O bottlenecks hidden in virtualized environments,allowing IT managers to allocate full network resources directly to virtualized applications. SFN5151T enables the highest performance and lowest CPU utilization in virtualized servers.

Lowest Power

At less than 8 Watts, the SFN5151T consumes less than half the power of the leading competitors’ products, and delivers 5-10x the efficiency of 1G Ethernet (Gbps/Watt). This not only makes a power efficient 10G network possible, it can save thousands of dollars of operating costs for a typical data center. The SFN5151T is the only single-port 10GBASE-T server adapter that is compatible with the Energy Star® guideline for power consumption.
