XtremeScale™ X2541
100GbE Ultra-Low Latency Network Adapters

overview
Xilinx’s XtremeScale™ X2541 single-port 10/25/40/50/100G Ethernet network
adapters are designed for high-performance electronic trading environments, andcloud 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 adapters provide realtime packet and flow information to thousands of virtual NICs. This combination ofultra-high bandwidth, ultra-low latency, ultra-scale connectivity, and packet telemetry
allows X2 series adapters to scale with each server, virtual machine or container.

ACCELER ATIONTARGET APPLICATIONS

For electronic trading environments, Onload® kernel bypass application
acceleration and DPDK services deliver superior small packet performance with
sub-microsecond hardware latency.

> Electronic Trading Environments

Onload dramatically accelerates and scales network-intensive workloads such as
in-memory databases, software load balancers, and web servers. With Onload,datacenters can support 4X or more users on their cloud network while delivering
improved reliability, enhanced quality of service(QoS), and a higher return on
investment, without modification to existing applications.

> Bare Metal, Containers, and Virtualized
Environments

In addition, X2541 adapters support the precision time protocol(PTP)fabric service
for apps that require synchronized time stamping of packets down to single-digit
nanosecond resolution.

HIGHLIGHTS> Sub-microsecond Latency

TELEMETRY> Near-zero Jitter

SolarCapture® Pro packet capture software enables X2541 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 torun applications such as high-precision network performance monitoring, analysis,and regulatory compliance.

> Highly Scalable

WORKLOADSThe X2541 adapters are ideal for scale-out cloud,web, and CDN application
environments. Use cases include software-defined networking(SDN), network
functions virtualization (NFV), web content optimization, DNS acceleration, web
firewalls, load balancing, No SQL databases, caching tiers(Memcached), web
proxies, video streaming, and storage networks.
X2541 adapters speed up TCP, unicast, multicast and UDP traffic for a wide varietyof trading applications. From mission-critical exchange gateways and matchingengines on the financial exchange side, to feed handlers, order routing, algorithmic
trading engines, messaging applications, order execution, data distribution andclient communications on the trading side, XtremeScale network adapters are
considered the de facto standard in electronic trading environments.
