SFN8522 PLUS adapters accelerate, monitor, and secure your network by providing:

  • Ultra-low latency (sub 1usec)
  • High packet rate (30Mpps for 2x10G)
  • Revolutionary tamper resistant adapter security
  • VXLAN, NVGRE, and GENEVE checksum offload
  • Management Control Transport Protocol Security through sideband management over PCl
  • Supports all Solarflare AppFlex software

The PLUS variant of the Flareon Ultra 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 as well as PPS and PTP time synchronization support.

The SFN8522-PLUS is capable of associating a hardware time-stamp with every incoming and outgoing Ethernet frame for application troubleshooting or performance monitoring. These features make the SFN8522-PLUS 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.

Capabilities such as ultra-low latency, Onload kernel bypass, class leading precision clock synchronization accuracy, SolarSecure Filter Engine, SolarCapture and more can be enabled to run on any SFN8500 adapter on the network, making this the one Ethernet adapter to deploy across your data center or cloud infrastructure.

CPU-Efficient Networking

The Flareon Ultra SFN8522 dual-port 10G Ethernet SFP+ server adapter delivers faster, more efficient processing of network traffic to accelerate a wide range of applications.

The SFN8522 adapter is an ideal workhorse for 10GbE data center and cloud workloads, providing high bandwidth, high-packet rate and CPU-efficient processing of network traffic.

Configurable Software

When configured with Solarflare software licenses, the SFN8522 can address ultralow latency applications, precision clock synchronization and hardware time stamping, packet filtering, packet capture and more.

Adapters can be purchased preconfigured with popular software bundles, or configured on-site with software options.

Ultra-Low Latency

Flareon Ultra SFN8522 offers fast and efficient hardware that optimizes packet flow to and from the user application.

When configured for ultra-low latency, the SFN8522 delivers unrivaled sub-microsecond latency. With Onload, the industry’s best applicationto-application performance is enabled via Solarflare’s unique and patented kernel bypass techniques.

Scalable, High-Performance Virtualization

Flareon Ultra SFN8522 provides unmatched performance and scalability in virtualized environments.

Solarflare is the proven leader in VM density and performance, and the SFN8522 raises the bar with 2048 vNICs, SRIOV and overlay network acceleration (VXLAN, NVGRE). In addition, the SFN8522 supports kernel bypass running in a guest VM, so users can run Onload or SolarCapture in a virtualized or cloud environment.

Accelerating Cloud, Web and CDN Apps

Flareon Ultra SFN8522 provides high bandwidth, high packet rate and CPU efficient processing of network traffic, making it ideal for scale-out cloud, web and CDN application environments.

Solarflare adapters are used in a wide range of use cases, including web content optimization, DNS acceleration, web firewalls, load balancing, NOSQL databases, caching tiers (Memcached) and web proxies.

In addition, when used with Onload, the SFN8522 further reduces host processing overhead and accelerates web and cloud traffic. When used with SolarSecure Filter Engine, the SFN8522 provides an additional layer of defense against DDoS attacks at the network ingress point to the Server. Attacks can be absorbed without degradation of “good” traffic, enabling a 3 to 4x improvement in packet-level filtering server headroom.*
