NVIDIA BlueField-2 DPU Network Card (MBF2H516C-CESOT)

1. Product Overview

The NVIDIA BlueField-2 Data Processing Unit (DPU) model MBF2H516C-CESOT is a high-performance, programmable network card designed for modern data centers. It combines powerful Arm® cores with ConnectX-6 Dx network adapter technology to offload, accelerate, and isolate data center infrastructure tasks like networking, storage, and security. This NIC card supports dual-port 100Gb/s Ethernet connectivity and is ideal for accelerating AI, cloud, and enterprise workloads.

2. Key Characteristics

• Dual-port 100Gb/s Ethernet connectivity via QSFP56 cages
• 8x Arm® Cortex-A72 cores running at up to 2.75GHz
• Hardware offloads for networking, storage, and security
• 16GB DDR4 memory with ECC protection
• 128GB eMMC onboard storage
• PCIe Gen 4.0 x16 host interface
• Out-of-Band (OOB) 1GbE management port

3. Core Technologies

The BlueField-2 DPU leverages NVIDIA’s DOCA software framework, RoCE (RDMA over Converged Ethernet), and hardware acceleration for NVMe over Fabrics, TLS/IPSEC encryption, and virtualization. It supports SR-IOV, GPUDirect® RDMA, and PCIe atomics for high-performance computing environments.

4. Working Principle

The BlueField-2 network card operates as a standalone data-centric processor. It offloads infrastructure functions from the host CPU, handling tasks such as packet processing, encryption, and storage protocols directly on the card. The integrated Arm cores run a full Linux OS, enabling custom application deployment and secure service isolation.

5. Applications

• Software-Defined Storage (SDS) and Hyper-Converged Infrastructure (HCI)
• AI and Machine Learning training clusters
• Cloud and Enterprise Data Center Networking
• Network Function Virtualization (NFV) and Security Offload
• High-Performance Computing (HPC) and Big Data analytics

6. Specifications
