The SFN5121T Dual Port 10 Gigabit Ethernet Enterprise Server Adapter from Solarflare is designed to optimize virtualized application performance. With triple-speed 10GBASE-T, it supports asymmetric upgrades. Servers can be upgraded asynchronously with switches at the other end of the wire as 10GBASE-T autonegotiates with 1000BASE-T and 100BASE-TX.

Equipped to handle the application loads of multi-core processors, the adapter delivers performance scaling for high-density server deployments. It also supports data networking with concurrent support of iSCSI and NAS traffic. The Receive Side Scaling (RSS) distributes IPv4/IPv6 loads across all CPU cores and MIS-X minimizes interrupt. In addition, Intel QuickData technology uses host DMA engines to accelerate input/output.

The adapter supports Solarflare's OpenOnload application accelerator, a full-featured high performance user-level network stack for Linux. The adapter accelerates guest applications in leading hypervisors, supporting NetQueue and VMQ in VMware and Hyper-V, and SR-IOV in KVM and XenServer.

Application Performance
This adapter delivers low latency at high message rates along with 40 Gb/s bi-directional line-rate performance. Featuring a set of stateless offloads, it provides efficient acceleration of network protocol tasks.
OpenOnload Application Accelerator
The adapter supports Solarflare's OpenOnload application accelerator, a full-featured user-level network stack for Linux. OpenOnload provides unprecedented performance with application compatibility and protocol compliance, bypassing kernel and networking overheads. The application accelerator also features binary compatibility with standard APIs and applications.
Scalable, Hardware-Assisted Virtualization
With additional vNICs and virtual PCIe functions, input/output performance scales as the number of CPU cores and virtual machines increase, resulting in enhanced application performance. The adapter accelerates guest applications in leading hypervisors, supporting NetQueue and VMQ in VMware and Hyper-V, and SR-IOV in KVM and XenServer. It eliminates network input/output barriers hidden in virtualized environments, allowing IT managers to allocate full network resources directly to virtualized applications. The adapter also enables high performance and low CPU utilization in virtualized servers.
Energy Efficient
It consumes 12.9W of power and delivers better efficiency of 1G Ethernet (Gb/s/W). In addition, the server adapter is certified with the ENERGY STAR guideline for power consumption.
