Features

Key features and benefits:

Sub-microsecond latency
Near-zero jitter
Highly scalable
Predictable, deterministic system performance
High message rates
Precision Time Stamping for accurate synchronization
NVMe/TCP storage ready
SolarCapture Pro network performance monitoring

The Solarflare X2522 adapter supports the Onload kernel bypass application acceleration and DPDK services which deliver superior small packet performance with sub-microsecond hardware latency, essential for electronic trading environments.

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 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.

In addition, the X2522 adapter supports the precision time protocol (PTP) fabric service for apps that require synchronized time stamping of packets down to single-digit nanosecond resolution.

SolarCapture Pro packet capture software enables the X2522 adapter 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 performance monitoring, analysis, and regulatory compliance.

The X2522 adapter is 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, 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.
The X2522 is ideal for electronic trading environments, from mission-critical 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.
