3U VPX GPU Switch Module

VPX3U-BW2000E-SWITCH Rugged SOSA-Aligned GPU and Network Switching Module

The VPX3U-BW2000E-SWITCH 3U VPX GPU switch module from WOLF Advanced Technology.  Firstly, it combines NVIDIA RTX™ Blackwell GPU acceleration with PCIe Gen4.  In addition, a 200 GbE switching capability in a single conduction-cooled VPX slot. Designed for aerospace and defence edge computing platforms.  It enables real-time AI processing, high-speed sensor data routing, and mission-system networking within space-constrained OpenVPX architectures.

At Metromatics, this 3U VPX GPU switch module supports system designers building SOSA-aligned mission computers requiring both switching fabric capability and GPU acceleration in one rugged embedded module.

Switch and GPU Acceleration in One 3U VPX Slot

Unlike traditional VPX GPU payload cards, the VPX3U-BW2000E-SWITCH operates as both:

• a system switching module
• a GPU compute acceleration node

This reduces the number of modules required inside a 3U VPX chassis while enabling efficient routing of PCIe and Ethernet data between mission-system payload cards. The integrated network switch supports up to eight 25 GbE links for high-bandwidth sensor and processor interconnect applications.

This architecture improves:

• chassis slot efficiency
• system SWaP optimisation
• internal data movement performance
• distributed sensor processing workflows

NVIDIA Blackwell GPU for AI and Video Processing

The integrated NVIDIA RTX™ 2000 Blackwell GPU delivers high-performance embedded processing for:

• real-time AI inference
• ISR video analytics
• multi-sensor fusion pipelines
• hardware-accelerated video encode and decode
• edge-based autonomy workloads

Fifth-generation Tensor cores support advanced AI precision formats including FP4, FP6, and FP8 Gen2, improving performance across deep-learning inference and high-performance embedded computing applications.

Hardware-accelerated NVENC and NVDEC engines support efficient 4K and 8K video encoding and decoding without loading the host CPU.

High-Speed PCIe Gen4 and 200 GbE Switching Capability

This 3U VPX GPU switch module integrates both PCIe and Ethernet switching functions to support high-bandwidth mission-system architectures.

Capabilities include:

• PCIe Gen4 switching between VPX modules
• GPU-direct data routing
• distributed compute fabric architectures
• high-rate sensor ingest pipelines
• TSN-enabled deterministic communications

The integrated switching fabric enables efficient routing of GPU-bound processing data while maintaining additional PCIe lanes for system-level traffic between other payload modules.

SOSA-Aligned OpenVPX System Integration

The VPX3U-BW2000E-SWITCH supports:

SOSA slot profile 14.4.15

This ensures compatibility with modern modular defence architectures including:

• ISR mission computing platforms
