The Onload® variant of the XtremeScale™ SFN8522 dual-port 10GbE SFP+ server I/O adapter adds a suite of enabled software capabilities that provide out-of-the box support for ultra-low latency Onload-accelerated sockets. These features make the SFN8522-Onload the ultra-low latency Ethernet adapter of choice to deploy as a key component throughout financial trading infrastructures where two ports of 10GbE are required.

CPU-EFFICIENT NETWORKING
The XtremeScale SFN8522-Onload dual-port 10GbE Ethernet SFP+ server adapter delivers faster, more efficient processing of network traffic to accelerate a wide range of applications. The SFN8522-Onload has 8 lanes of PCIe 3.1 minimizing latency and maximizing bus throughput between the adapter and the host.

FLEXIBILITY IN OPERATION
In a virtualized environment the adapter supports hypervisor bypass via SR-IOV providing virtualized guests with near baremetal network performance. Onload adds the option of kernel bypass in Linux guests, providing virtualized applications the lowest possible network latency even while virtualized. Multiple physical functions are also available enabling the ports to be partitioned when connected to 802.1Q trunked switch ports with a logical interface per VLAN being presented to the operating system.

ULTRA-LOW LATENCY
The XtremeScale SFN8522-Onload offers fast and efficient hardware that optimizes packet flow to and from the user application. The SFN8522-PLUS unlocks unrivaled submicrosecond latency both at Layer 2 and TCP and UDP via Onload.

ONLOAD
Onload is Solarflare's industry-leading fully RFC-compliant kernel-bypass user-space TCP/IP stack. Unrivaled application-toapplication TCP and UDP latency is available with no modification to the applications being accelerated. Applications may communicate via Onload to any other RFC-compliant TCP/IP stack with seamless interoperability.
