Details

Datacentre Infrastructure Chip

The BlueField-2 data processing unit (DPU) is the world’s first data centre infrastructure-on-a-chip optimised for traditional enterprises’ modern cloud workloads and high performance computing.

It delivers a broad set of accelerated software defined networking, storage, security and management services with the ability to offload, accelerate and isolate data centre infrastructure.


Ethernet or Infiniband

With its 200Gb/s Ethernet or InfiniBand connectivity, the BlueField-2 DPU enables organizations to transform their IT infrastructures into state-of-the-art data centres that are accelerated, fully programmable, and armed with “zero trust” security to prevent data breaches and cyber attacks.

DOCA

The new NVIDIA DOCA SDK enables developers to build applications on DPU-accelerated data center infrastructure services, much like the NVIDIA CUDA® programming model enables developers to build GPU-accelerated applications.
