[DigitalToday reporter Chi-gyu Hwang (황치규)] Nvidia has unveiled a BlueField-4 STX reference architecture that can be used to build storage systems for AI clusters, SiliconANGLE reported on March 17 local time.
The architecture is based on the BlueField-4 data processing unit (DPU) and manages data traffic between GPUs and flash storage. It includes Spectrum-X Ethernet switches and ConnectX-9 SuperNIC to support higher AI storage performance.
The company said BlueField-4 STX can process data tokens used in AI models 5 times faster than existing storage architectures, while improving energy efficiency 4-fold. It can also optimise management of the key-value cache, which is important for large-scale AI workloads.
Nvidia expects partners to ship BlueField-4 STX systems from the second half of 2026.
