NVIDIA BlueField-2 DPU

NVIDIA BlueField-2 DPU

Data Center Infrastructure on a Chip

The NVIDIA BlueField-2 Data Processing Unit (DPU) redefines modern data center infrastructure by combining networking, storage, security, and management capabilities into a single, powerful platform.

As the world’s first true data center infrastructure-on-a-chip, the BlueField-2 DPU is specifically engineered to meet the needs of high-performance computing (HPC), cloud workloads, and enterprise IT environments looking to maximize efficiency, security, and scalability.

By offering accelerated software-defined services and full programmability, BlueField-2 enables businesses to transform their IT operations, streamline data management, and implement “zero trust” security architectures.

Its advanced capabilities deliver not just performance but also reduce the total cost of ownership (TCO) and boost overall data center ROI.

Key Benefits and Value Proposition

• Data Center Infrastructure on a Chip: Integrates networking, storage, security, and management services in a single DPU.
• 200Gb/s Connectivity: Supports both Ethernet and InfiniBand protocols, offering flexible high-speed data transfer.
• Accelerated Software-Defined Networking (SDN): Offloads and accelerates tasks traditionally handled by the CPU.
• Zero Trust Security Architecture: Ensures data integrity and protection against cyber-attacks and data breaches.
• Programmable with NVIDIA DOCA Framework: Developers can easily create custom applications to leverage the full power of the DPU.
• Lower Total Cost of Ownership (TCO): Reduces CPU load, improves server utilization, and optimizes overall data center performance.

Technical Overview
