High Performance Networks (HPNs) use kernel bypass operations to deliver extreme performance over a standard 10Gb Ethernet (10GbE) network. By circumventing the OS stack, performance gains are achieved, enabling applications to achieve ultra low latency, high throughput with maximum bandwidth utilization, low jitter and all with low CPU overhead, saving on power and cooling costs as well.
There are many market drivers of an HPN, such as:
- [High Frequency Trading] HFT involves placing and then pulling multiple orders faster than the blink of an eye…It represent (sic) between half and three-quarters of trading volume on top exchanges and a rising share of futures and other derivatives markets. (Reuters, “EU regulators urge caution on fast trading curbs,” April 24, 2012)
- What many administrators and security professionals are looking for today is actionable intelligence that can predict attacks, spot them in progress and react to them in near-real time. (Government Computer News, “The path to outsmarting advanced cyberattacks,” April 18, 2012)
- As shown in the chart below, Cisco reports a five times increase in video application traffic (measured in exabytes) over IP neworks (Cisco VNI June 2011 – Cisco’s Global IP Traffic Forecast – Monthly Usage Video Applications).
With an HPN, companies can increase their competitiveness. For example, for the above HFT company, an HPN delivers lower transaction latency by three to four microseconds through kernel bypass operations. Many companies report a gain tens of thousands of dollars with just one microsecond lower latency for one transaction.
Emulex understand HPNs and the value they bring to companies. Our new OCe12000 Network Xceleration solutions provide unsurpassed performance. Read our white paper (found here), and check out our HPN solution site to learn more!
