The Solarflare® 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 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 SFN5121T also delivers unmatched power efficiency for the consolidation and deployment of high-density servers. The SFN5121T supports data networking with concurrent iSCSI and NAS traffic – while providing cost effective, power-efficient and high-performance network I/O.
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 also meets the Energy Star™ requirement of less than 8 Watt/port power consumption.
SCALABLE, HARDWARE-ASSISTED VIRTUALIZATION
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 over the competition, it scales as the number of CPU cores and virtual machines increases for better performance and manageability.
LEADERSHIP APPLICATION PERFORMANCE
The SFN5121T has the industry’s lowest-latency along 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. The SFN5121T features hypervisor bypass and SR-IOV used to accelerate guest applications in leading hypervisors, including VMware, Hyper-V, and XenServer via direct guest access. This relieves network I/O bottlenecks hidden in virtualized environments, allowing IT managers to allocate network resources directly to applications. This enables the best performance and lowest CPU utilization in virtualized servers. The SFN5121T is driver compatible with the SFN5122F product. It also supports Solarflare’s OpenOnload® application accelerator, a high-performance user-level network stack for Linux. OpenOnload bypasses kernel networking overheads and is binary compatible with standard APIs and applications.
