®

SFN5121T dual-port, triple-speed 10GBASE-T enterprise server adapter delivers

the industry’s best application performance, lowest power consumption, and most scalable 

virtualization – enabling unmatched data center performance over installed and new UTP 

cabling.

With triple-speed 10GBASE-T, the SFN5121T

supports asymmetric upgrades. Because

10GBASE-T autonegotiates with 1000BASE-T

and 100BASE-TX, servers can be upgraded

asynchronously with switches at the other

end of the wire. Equipped  to handle the 

application loads of the latest multi-core

processors, it delivers unmatched performance

scaling for high-density server deployments,

while utilizing a single driver across all 

Solarflare server adapter products. The

SFN5121T supports data networking with

concurrent support of iSCSI and NAS traffic –

while remaining true to the need for cost- 

effective, power-efficient and high-performance

network I/O.

SFN5121T delivers the industry’s lowest

latency at the highest message rates to

customers with leading edge enterprise data

center deployments. SFN5121T also

delivers the industry’s highest message rate

and lowest latency jitter, with full 40 Gbps

bidirectional line-rate performance. Featuring

a rich set of stateless offloads, it provides

efficient acceleration of the most demanding

network protocol tasks.

SFN5121T supports Solarflare’s OpenOnload

®

application accelerator, a full-featured, high-

performance user-level network stack for

Linux. OpenOnloadprovides unprecedented

performance with application compatibility

and protocol compliance, bypassing kernel

and networking overheads, while featuring

binary compatibility with standard APIs and

applications.

The SFN5121T 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 SFN5121T accelerates guest applications

in leading hypervisors, supporting NetQueue

and VMQ in VMware and Hyper-V, and

SR-IOV in KVM and XenServer. SFN5121T

relieves network I/O bottlenecks hidden in

virtualized environments, allowing IT managers

to allocate full network resources directly to

virtualized applications. SFN5121T enables

the highest performance and lowest CPU

utilization in virtualized servers.

At less than 13 Watts, the SFN5121T 

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 SFN5121T is also

compatible with the Energy Star

®

guideline

for power consumption.
