Summary
NVIDIA BlueField-4 is the next-generation DPU in NVIDIA’s BlueField family, positioned for AI factory infrastructure, AI-native storage, context memory, security, networking, and offload. Current public NVIDIA pages connect BlueField-4 directly to NVIDIA-STX and NVIDIA-CMX designs for storage/context processing.
Detail
Purpose
BlueField-4 extends the BlueField DPU role from host networking and infrastructure offload into AI-native data infrastructure. In NVIDIA’s latest public material it appears as a storage/context processor that can manage NVMe, integrity, encryption, key-value cache, and low-latency access paths for agentic AI workloads.
Current public positioning
- DPU generation following BlueField-3.
- Used in NVIDIA-STX AI-native storage reference architecture.
- Used in NVIDIA-CMX context memory storage platform.
- Used in the NVIDIA-Vera-Rubin-POD BlueField-4 STX rack, which hosts CMX context memory storage for POD-scale agentic inference.
- Works with NVIDIA-DOCA software and DOCA Memos for context/KV-cache workflows.
- Fits NVIDIA-AI-Data-Platform and NVIDIA-Enterprise-AI-Factory designs where storage, security, networking, and compute are co-designed.
