XtremeScale™ SFN8522
Dual-Port 10GbE SFP+ Network Adapter

Solarflare’s XtremeScale™ SFN8500 adapter family provides the best performance yet, with higher bandwidth, lower
latency and higher packet rates. 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 suchas ultra-low latency, Onload® kernel bypass, class-leading clock synchronization accuracy providing MIFID II readiness,ServerLock® NIC-based firewall, 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 NETWORKINGThe XtremeScale SFN8522 dual-port 10G Ethernet SFP+ server adapter delivers faster, more efficient processing ofnetwork traffic to accelerate a wide range of applications. The SFN8522 has 8 lanes of PCle 3.1 making it an ideal workhorsefor 10GbE data center and cloud workloads, providing high bandwidth, high packet-rate and CPU efficient processing ofnetwork traffic.
CONFIGURABLE SOFTWARE
When configured with Solarflare software licenses, the SFN8522 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 APPLICATIONSThe SFN8522 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 contentoptimization, 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 thenetwork. In addition, when used with Onload, the SFN8522 further reduces host processing overhead and accelerates weband cloud traffic.
SECURING THE SERVER
The SFN8522 adapter includes Solarflare’s ServerLock firmware which is digitally signed with an ECC384 signature to ensure
tamper resistance while including a hardware based filter engine that can be leveraged to secure all the traffic enteringand leaving the server. This can be enabled by installing ServerLock Local or binding the NIC to a ServerLock Manager inan enterprise configuration.
SCALABLE, HIGH-PERFORMANCE VIRTUALIZATION
Solarflare is the proven leader in VM density and performance, and the SFN8522 sets 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 ultra-low 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.
