Did you know?
Extremely low latency and high throughput enables the Solarflare X2522-Plus adapter to provide real-time packet and flow information to thousands of virtual NICs. This combination of ultra-high bandwidth, ultra-low latency, ultra-scale connectivity, and packet telemetry allows the adapter to scale with each server or virtual machine.

Part number information

The following table provides the ordering part numbers and feature codes for the Solarflare X2522 adapter.

Table 1. Ordering information

The option part numbers includes the following items:

• One Ethernet adapter
• Full-height (3U) bracket attached with low-profile (2U) bracket included in the box
• Documentation

Note: The adapter ships without any SFP28 transceivers or direct attach cables. These items must be ordered separately as listed in the following section.

Supported transceivers and cables

The Solarflare X2522 adapter has empty SFP28 cages for connectivity. The adapter either supports connections to a 10 Gb or 25 Gb switch or can share a connection to a 100 Gb switch using a 4:1 breakout cable.

The following table lists the supported transceivers.

Table 2. Transceivers

25Gb transceivers: When installed in the Solarflare X2522 Ethernet adapter, the supported 25Gb transceiver will currently only operate at 25Gb/s speeds.

The following table lists the supported fiber optic cables and Active Optical Cables.

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.
