Solarflare Unveils Cloud Onload Application Acceleration Platform

Application-optimized network solutions provider, Solarflare, has launched its Cloud Onload application acceleration platform – designed to allow data centers to “reclaim 25 percent or more in server resources” by improving server efficiency and performance.

The first in a planned family of application acceleration products, Cloud Onload is the cornerstone of the company’s plan to remove billions of dollars of waste from today’s

private and public cloud infrastructure investments. Customers can convert wasted servers into valuable services for their customers, leading to increased revenue and lower costs.


“Today’s consumers expect advanced ecommerce shopping experiences, enhanced video streaming, and generally higher service levels at falling, or at most, equal prices,” said Russell Stern, president and CEO of Solarflare. “Our groundbreaking Cloud Onload application acceleration platform is a major step forward for data centers that want to provide superior end user experiences, while saving millions of dollars in new infrastructure investments.”

Load Balancers, Web Servers

Solarflare’s Cloud Onload would significantly accelerate and scale a data center’s network-intensive in-memory databases, software load balancers, and web servers so a single server can do the work of four with improved reliability, enhanced quality of service (QoS), and higher return on investment.

The platform would reduce latency while increasing transaction rates for nearly all network-intensive Transmission Control Protocol (TCP) applications on physical servers as well as in virtualized environments.

Solarflare claims that benchmark testing has demonstrated the following performance improvements:

  • In-memory databases including Couchbase, Memcached, and Redis: 2X
  • Software load balancers including NGINX and HAProxy: 2-10X
  • Web servers/applications including NGINX and Node.js: 50 percent

“Our groundbreaking Cloud Onload application acceleration platform is a major step forward for data centers,” said Russell Stern, president and CEO of Solarflare.

Data centers can use the platform to achieve Remote Direct Memory Access (RDMA)-like performance without any modifications to existing software applications. Tailored to run in any Linux environment, whether open source, bare metal, virtual machine, or container, Solarflare’s Cloud Onload is fully POSIX compliant to ensure compatibility with TCP-based applications, management tools, and network infrastructures.

“Solarflare’s patented kernel bypass technology, which has become the de facto standard for the world’s electronic trading platforms, enables Cloud Onload to improve application acceleration by as much as 10X while significantly reducing CPU utilization,” said Steve Pope, co-founder and CTO of Solarflare. “The demand for this approach grows with the adoption of faster networks and modern web applications.”

100GbE Networks

Available now, Solarflare’s Cloud Onload application acceleration platform runs on 10/25/40/50/100GbE networks. For more information about Cloud Onload, visit
