Lenovo Solarflare SFN7122F 2x10GbE SFP Plus Flareon Ultra Dual Port 10

GbE Adapter

Product Guide

The Solarflare SFN7122F 2x10GbE SFP+ Flareon Ultra is a high-performance dual- port 10 GbE adapter that enables the lowest latency networking solutions for electronic/high frequency trading and other latency-sensitive applications. The adapter accelerates HPC and Hadoop by providing high message rate and low latency interconnects for compute clusters. The adapter’s CPU offload along with high performance enables servers to provide more services to more users in cloud and grid environments.

Did you know?
With a latency of less than 2 microseconds, the SFN7122F adapter, when combined with OpenOnload application acceleration middleware, offers upwards of 25% lower latency than the SFN6122F adapter. This extremely low latency is ideal for the financial services industry, where low latency and high performance TCP and UDP processing are important attributes for a network interface.

Features

Based on Solarflare’s fourth-generation SFC9120 Ethernet controller, the SFN7122F adapter delivers dual-port, line-rate 10 Gbps throughput for moving large amounts of data and eliminating server I/O bottlenecks. The adapter delivers industry-leading network performance with ultra-low latency at the highest message rates.
The adapter has the following features:

• Delivers industry-leading performance, providing high throughput, low latency, and high processor efficiency, which improves the performance of network communications, network-attached storage, and remote file system access.

• Suitable for applications such as email, database, OLTP, data mining, web serving, and big data.

• Includes Solarflare’s unique hardware-accelerated virtual channel architecture. Each virtual channel provides an independent channel between the network adapter and host software, allowing network I/O processing to be distributed efficiently over multiple processor cores. With 1024 virtual channels per port (2048 per adapter), I/O performance scales as the number of processor cores and virtual machines increase.
  Note: In the Solarflare documentation, the virtual channel feature is referred to as vNIC. This feature is different from the Virtual Fabric vNIC capability.

• Supports PCIe 3.0 with ultra-low latency features, such as direct packet transfer (Tx PIO) mode and the templated send API.

• Features hardware acceleration to optimize packet delivery, such as UDP multicast replication, integrated Layer 2 switching capability and VLAN insertion/removal, along with TCP segmentation offload (TSO) to reduce processor load.

• Supports Receive Flow Steering (RFS) acceleration, which improves processing efficiency by steering received packets to the processor core that is running the application that consumes those packets.

• Accelerates guest applications in leading hypervisors by efficiently distributing virtual machine network I/O traffic across multiple processor cores while supporting NetQueue and VMQ in VMware, and Microsoft VMQ in Hyper-V.

• At fewer than 6 watts, the adapter consumes less than half the power of the leading competitor’s products, and can deliver 5x – 10x the efficiency of 1G Ethernet (Gbps per watt). This results in a power-efficient 10G network that can save thousands of dollars of operating costs for a typical data center

• Graphical user interface and scriptable command-line interface for ease of management.

In addition, the adapter supports the Solarflare OpenOnload application acceleration middleware on Linux operating systems. OpenOnload bypasses the network stack in the Linux kernel by dedicating a virtual channel to each accelerated application.
OpenOnload enables the following capabilities:

• Suitable for the most demanding, latency-sensitive applications in environments requiring the highest message rates.
• Delivers ultra-low latency and high throughput even as message rates increase.
• Enables accelerated application performance through TCP/IP, UDP, and multicast acceleration. Streamlines and reduces interrupts, context switches, and data copies.
• Reduces the processing that is associated with networking and improves processor core scaling.
• Increases message rates by 300% or more.
• Binary compatibility with industry standard APIs, so no software modifications are needed, and OpenOnload seamlessly integrates in to the existing infrastructure.
• A standards-based solution using TCP/IP and UDP, so no specialized protocols are needed.
  Note: Solarflare OpenOnload runs only on non-Xen Linux distributions. Windows and VMware are not supported.
