Solarflare XtremeScale X2522 25G PCIe Adapter

The World's Lowest Latency 10/25G Ethernet NIC - The Industry's 1st Standard NIC with HW Security


The X2522 dual-port 10/25G Ethernet NIC is a member of the X2 family of XtremeScale products that redefine the price/performance of standard NICs for modern data centres.

Designed from the ground up for virtualised dense server environments, Solarflare XtremeScale X2 adapters are the most cost-effective NICs in the industry for Ethernet connectivity. At the same for day's modern class of applications. XtremeScale X2 is the only general-purpose NIC with 2,048 Virtual NICs, programmable packet processing engine for network off-load and real-time packet/flow capture required by your network performance management and analytics platforms.

Acceleration Services Allow Distributed Apps to Scale-Out

The challenge with distributed apps is keeping hardware and system latency low, while scaling to thousands of tasks running across thousands of cores. The X2522 harnesses kernel bypass acceleration technology to deliver superior small packet performance with latency as low as one-half microsecond. Solarflare kernel bypass technologies include Onload, ScaleOut Onload and DPDK acceleration services provide servers the headroom needed to handle more processes in the same amount of time and/or with less servers.

Solarflare acceleration technology can also be used in to build ultra-low latecy NVMe all-flash storage fabrics. X2522 NICs configured for NVMe over standard-TCP - and with kernel bypass acceleration - provide the same performance as NVMe fabrics based on special-purpose RDMA fabrics.

Precision Time Stamping for Accurate Synchronisation

The X2522 supports the precision timing protocol (PTP) fabric service for apps that require synchronised time stamping of packets down to the single-nanosecond.

Protect Traffic "Inside" the Data Centre by Deploying the Industry's 1st Standard NICs with HW Security On-Board

ServerLock technology inside every standard X2522 NIC complements firewall perimeter security. It is now possible to scale security inside your data centre by using micro-segmentation to scale packet surveillance, filtering, cloaking and firewalling with every server.

Real-Time Telemetry Feeds NPM & Analytics

The X2522 provides real-time monitoring, inspection and capture of packets needed for network performance management, security analytics, or compliance. Packet data can be forwarded to a libpcap API or saved to a file with hardware timestamps.

A Platform for Micro-Segmented NIC Fabric Services

For modern data centres, X2522 lays a new foundation for NIC-based network virtualisation needed for their highly distributed applications with thousands of inter-connected web server, machine learning and big data workloads. X2522 is the first and only standard NIC platform that can establish ultra-scale connectivity to thousands of virtual NICs, while at the same time providing real-time packet and flow information. The combination of ultra-high bandwidth, ultra-low latency, ultra-scale connectivity and packet telemetry, allows X2522 NICs to serve as the Industry's first commercial platform for micro-segmented NIC fabric services that scale with each server, VM or container.

The Most Cost Effective NICs in the Industry

Solarflare makes data centre-wide deployment of these capabilities cost-effective. Although X2522 NICs provide superior performance and SmartNIC-like ability to enable network services, a 25GbE X2 NIC from Solarflare offers a cost advantage over comparably configured NICs from market share leaders Broadcom, Intel and Mellanox.
