Conventional NICs can’t Scale with Today’s Web Servers. Use Solarflare Software Defined NICs to Improve Socket Performance, CPU Efficiency, and Scalability.

All XtremeScale server NICs from Solarflare now include ScaleOut Onload. While kernel-based drivers (and their context switches and buffer copies) inhibit web server performance, Solarflare’s ScaleOut Onload provides the maximum performance. Testing with NGINX, the most popular web server software on the planet, demonstrates that Solarflare’s ScaleOut Onload increased page hosting performance by 120%. The kernel bypass architecture of our ScaleOut Onload technology significantly reduces data copies, eliminates host CPU context switches, and intelligently steers traffic to cores servicing page requests, all while dramatically improving communications socket re-use. And if you still want a kernel-based solution, Solarflare's cut-through reduces CPU I/O workload, allowing the CPU to support more web service scalability.

The Solarflare Scale-Out Performance Advantage

The Problem: Kernel IOPS Impact

For dedicated application servers like those for Web Services, going through the kernel for I/O impacts performance. This leads to shorter lifecycles for web servers.

The Solution: Solarflare ScaleOut Onload

Solarflare’s ScaleOut Onload speeds up I/O by cutting out the kernel, which simultaneously reduces CPU workload. The result: significantly higher IOPS rates, more CPU cycles available for applications, and longer server life.
