The new XtremeScale™ SFN8000 adapter family provides Solarflare’s best performance yet
with higher bandwidth
lower latency and higher packet rate. The SFN8000 family adapters are based on a common hardware platform
enabling customers to configure the features and performance they want to meet the particular needs of each application. Capabilities such as ultra-low latency
Onload® kernel bypass
class leading clock synchronization accuracy providing MIFID II readiness
ServerLock® Filter Engine
SolarCapture® Pro and more can be enabled to run on any SFN8000 adapter on the network
making this the one Ethernet adapter to deploy across your data center or cloud infrastructure.

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.
