NVIDIA launches BlueField-4 STX storage architecture with broad industry adoption

NVIDIA introduced the BlueField-4 STX, a modular reference architecture designed to facilitate deployment of accelerated storage infrastructures tailored for agentic Artificial Intelligence (AI) applications requiring long-context reasoning.

This architecture addresses challenges traditional data centers face in providing responsive storage that supports real-time data access and contextual memory for AI systems operating across multiple steps and sessions. The design aims to support enhanced throughput and responsiveness during inference, training, and analytics by keeping data close and accessible.

Technically, BlueField-4 STX is powered by the NVIDIA Vera Rubin platform and integrates the BlueField-4 processor, combining a Vera Central Processing Unit (CPU) with ConnectX-9 SuperNIC, Spectrum-X Ethernet, DOCA, and NVIDIA AI Enterprise software. The architecture delivers up to five times the token throughput and quadruples energy efficiency compared to traditional CPU storage architectures, alongside doubling data ingestion rates for enterprise AI.

The first rack-scale implementation includes the NVIDIA CMX context memory storage platform, which expands Graphics Processing Unit (GPU) memory with a high-performance context layer suitable for scalable inference and agentic AI systems. Numerous storage providers and manufacturing partners are designing infrastructure based on NVIDIA's modular reference, with early adopters including CoreWeave, Crusoe, IREN, Lambda, Mistral AI, Nebius, Oracle Cloud Infrastructure, and Vultr.

Jensen Huang, founder and CEO of NVIDIA, said, “Agentic AI is redefining what software can do — and the computing infrastructure behind it must be reinvented to keep pace. AI systems that reason across massive context and continuously learn require a new class of storage. NVIDIA STX reinvents the storage stack, providing a modular foundation for AI-native infrastructure that keeps AI factories operating at peak performance.”

The BlueField-4 STX platforms are scheduled to be available from partners during the second half of 2026, with ongoing collaborations involving Cloudian, DDN, Dell Technologies, Everpure, Hitachi Vantara, HPE, IBM, MinIO, NetApp, Nutanix, VAST Data, WEKA, Artificial Intelligence Cloud (AIC), Supermicro, and Quanta Cloud Technology supporting next-generation AI infrastructure development.
