Product Details
XtremeScale SFN8542 Dual-Port 40GbE QSFP+ PCIe 3.1 Server I/O Adapter

CPU-Efficient Networking
The XtremeScale 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 as one QSFP+ port can also operate as four 10GbE SFP+ ports

Configurable Software
When configured with Solarflare software licenses, the SFN8542 can address ultra-low latency applications, highly accurate clock synchronization and hardware time stamping, packet filtering, packet capture and more. Adapters can be purchased pre-configured with popular software bundles, or configured on-site with software options.

Ultra-Low Latency
The platform’s hardware optimizes packet flow to and from the user application. When licensed for ultra-low latency, it delivers unrivaled sub-microsecond TCP and UDP latency. With Onload, the industry’s best application-to-application performance is enabled via Solarflare’s unique and patented kernel bypass techniques.

Accelerating Applications
The SFN8542 is ideal for scale-out cloud, web and CDN application environments. Solarflare adapters are used in a wide range of use cases, including Software-defined networking (SDN), Network functions virtualization (NFV), web content optimization, DNS acceleration, web firewalls, load balancing, NOSQL databases, caching tiers (Memcached), web proxies, video streaming and storage networks. The SFN8542 also provides the ideal link between fast NVMe storage and the network. In addition when used with Onload, the SFN8542 further reduces host processing overhead and accelerates web and cloud traffic. When used with ServerLock 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
Solarflare is the proven leader in VM density and performance, and the SFN8542 raises the bar with 2048 vNICs, SR-IOV, overlay network acceleration e.g. VXLAN, NVGRE. In addition, the SFN8542 supports kernel bypass running in a guest VM, so users can run ultra-low latency Onload or SolarCapture Pro in a virtualized or cloud environment.

The SFN8542 is also fully flow-aware, providing flexible layer 2-4 flow processing and flow steering natively. The benefits are efficient flow acceleration in almost every environment from the data center to the stock exchange.
