PRODUCT BRIEF

Product Name
XtremeScale™ X2522

10/25GbE Ultra-Low Latency Network Adapters
OVERVIEW

Xilinx’s XtremeScale™ X2522 10/25G dual-port Ethernet network
adapters are designed for high-performance electronic trading
environments, and cloud and enterprise data centers; including
artificial intelligence, big data, analytics, machine learning, storage,
and telco applications.

NETWORKING

Record-breaking low latency and high throughput network adaptersprovide real-time packet and flow information to thousands ofvirtual NICs. This combination of ultra-high bandwidth, ultra-low
latency, ultra-scale connectivity, and packet telemetry allows X2series adapters to scale with each server, virtual machine orcontainer.

ACCELERATION

For electronic trading environments, Onload® kernel bypass
application acceleration and DPDK services deliver superior small
packet performance with sub-microsecond hardware latency.
Onload dramatically accelerates and scales network-intensive
workloads such as in-memory databases, software load balancers,
and web servers. With Onload, data centers can support 4X or moreusers on their cloud network while delivering improved reliability,
enhanced quality of service (QoS), and a higher return on
investment, without modification to existing applications.
In addition, X2522 adapters support the precision time protocol(PTP) fabric service for apps that require synchronized timestamping of packets down to single-digit nanosecond resolution.

TELEMETRY

SolarCapture® Pro packet capture software enables X2522
adapters to capture and time stamp packets in hardware, persist
packet to disk, and replay packets streams. This feature provides
the essential ingredient for corporate data centers to run
applications such as high-precision network performancemonitoring, analysis, and regulatory compliance.

TARGET APPLICATIONS> Electronic Trading Environments> Enterprise Data Centers> Bare Metal, Containers, andVirtualized Environments> Content Delivery Networks

HIGHLIGHTS> Sub-microsecond Latency> Near-zero Jitter> Highly Scalable> Predictable, Deterministic System
Performance> Industry’s Highest Message Rates> Precision Time Stamping for
Accurate Synchronization> Network Performance Monitoring

WORKLOADSThe X2522 adapters are ideal for scale-out cloud, web, and CDN application environments. Use cases include 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.
X2522 adapters speed up TCP, unicast, multicast and UDP traffic for a wide variety of trading applications. From missioncritical exchange gateways and matching engines on the financial exchange side, to feed handlers, order routing, algorithmic
trading engines, messaging applications, order execution, data distribution and client communications on the trading side,
XtremeScale network adapters are considered the de facto standard in electronic trading environments.

Adaptable. Intelligent.
