Onload Server Adapters

Solarflare Onload server adapters deliver the highest performance, lowest latency, and most scalable 10GbE solution in the industry. Onload server adapters are ideal for the most demanding, latency-sensitive applications in environments requiring the highest message rates. They also support OpenOnload® application acceleration middleware, which offers a unique combination of ultra-low latency and high message rate performance, with seamless application compatibility.

Solarflare Onload PTP server adapters combine the lowest latency at highest message rates with the highest precision server clock accuracy – all in a single server slot operating over a single 10GbE network.

The SFN5000 generation of Onload server adapters provides as much as 50% latency reduction and a 3x message rate improvement over Performant server adapters. (It should be noted that Performant server adapters provide as much as 2x the performance of competitive products.) The SFN6000 generation of Onload server adapters provides up to an additional 20% latency reduction (60% total reduction vs. Performant) and 2x message rate improvement over the SFN5000 generation (6x total message rate improvement vs. Performant adapters).
