Flareon Ultra SFN8542 Dual-Port 40GbE QSFP+ PCIe 3.1 Server I/O Adapter
The Flareon Ultra SFN8542 dual-port 40G Ethernet QSFP+ server adapter delivers faster, more efficient processing of network traffic to accelerate a wide range of applications. The SFN8542 has 16 lanes of PCIe 3.1 making it an ideal workhorse for 40GbE data center and cloud workloads, providing high-bandwidth, high packet rate and CPU-efficient processing of network traffic. The SFN8542 can be configured as a dual-port 40GbE or a quad-port 10GbE adapter (with four 10GbE ports from QSFP+) as one QSFP+ port can also operate as four 10GbE SFP+ ports.
When configured with Solarflare software licenses, the SFN8542 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.
Flareon Ultra SFN8542 offers fast and efficient hardware that optimizes packet flow to and from the user application. When configured for ultra-low latency, the SFN8542 delivers unrivaled sub-microsecond latency. With Onload, the industrys best application-to-application performance is enabled via Solarflares unique and patented kernel bypass techniques.
Accelerating Cloud, Web and CDN Apps
Flareon Ultra SFN8542 provides highbandwidth, 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 SFN8542 further reduces host processing overhead and accelerates web and cloud traffic. When used with SolarSecure Filter Engine, the SFN8542 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.*
Scalable, High-Performance Virtualization
Flareon Ultra SFN8542 provides unmatched performance and scalability in virtualized environments. Solarflare is the proven leader in VM density and performance, and the SFN8542 raises the bar with 2048 vNICs, SR-IOV, overlay network acceleration (VXLAN, NVGRE). In addition, the SFN8542 supports kernel bypass running in a guest VM, so users can run ultralow latency Onload or SolarCapture in a virtualized or cloud environment.
