Detailed Description Key Specifications Ordering Information

The XNM-KU-M4 is a ruggedized, FPGA-based storage module designed for mission-critical high-speed data recording and playback. Leveraging Xilinx KU115 FPGA and 4× M.2 NVMe SSDs, it delivers 4.8GB/s sustained read/write speeds with ultra-low latency, ideal for defense, aerospace, and industrial test applications.

Key Innovations

· Real-Time Recording: Captures high-speed data streams via QSFP+ (Aurora protocol) or fiber/RapidIO interfaces;

· Dual-Mode Access: Simultaneous high-speed playback (QSFP+) and network management (10GbE/FTP);

· Rugged Design: Supports both air-cooled and conduction-cooled deployments (-40°C to +85°C).

Why Choose XNM-KU-M4?

· Defense-Grade Reliability – FPGA-controlled NVMe avoids OS bottlenecks.

· Dual Data Paths – QSFP+ for real-time streaming + 10GbE for FTP management;

· Scalable Capacity – Upgrade SSDs without hardware changes;
