Flareon Ultra SFN8522 Server Adapter
Dual-Port 10GbE SFP+ PCIe 3.1
The new Flareon™ Ultra SFN8500 adapter family provides Solarflare’s best performance yet,
with higher bandwidth, lower latency and higher packet rate. The SFN8500 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, 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 has 8 lanes of PCle
3.1 making it an ideal workhorse for 10GbE
data center and cloud workloads, providing
high bandwidth, high-packet rate and CPUefficient processing of network traffic.
Configurable Software
When configured with Solarflare software
licenses, the SFN8522 can address ultralow latency applications, highly accurate
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
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 SFN8522 is ideal for scale-out cloud,
web and CDN application environments.
Solarflare adapters are used in a wide
range of use cases, including Softwaredefined 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 SFN8522 also provides the
ideal link between fast NVMe storage and
the network. 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 packetlevel filtering server headroom.*
Scalable, High-Performance
Solarflare is the proven leader in VM density
and performance, and the SFN8522 raises
the bar with 2048 vNICs, SR-IOV, overlay
network acceleration e.g. VXLAN, NVGRE.
In addition, the SFN8522 supports kernel
bypass running in a guest VM, so users can
run ultralow latency Onload or SolarCapture
in a virtualized or cloud environment.
The SFN8522 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.
