NVIDIA BlueField is a family of specialized data processing units (DPUs, Data Processing Units) designed to accelerate and optimize network functions in today's data centers. BlueField offloads tasks such as network management, security, data access, and virtualization from central processing units (CPUs), enabling high performance, security, and infrastructure efficiency.
Feature | Description |
Purpose | Hardware acceleration of networking (Ethernet, InfiniBand), storage (NVMe over Fabrics), and security (encryption, firewall, IDS/IPS, etc.) functions for data centers. |
Models and generations | BlueField-2, BlueField-3, BlueField-4 (upcoming). |
Network Capabilities | Up to 200 Gbps with BlueField-2, up to 400 Gbps with BlueField-3, up to 800 Gbps with BlueField-4 (upcoming). Ethernet and InfiniBand support. |
Processor cores | BlueField-2 - 8 ARM Cortex A72 cores; |
Memory | Up to 32GB DDR4 (BlueField-2) and DDR5 (BlueField-3) with ECC support. |
Interfaces | BlueField-2 - PCIe Gen4, |
Hardware acceleration | IPsec/TLS/AES-XTS encryption, compression, data deduplication, hard isolation, traffic filtering, RegEx processing, and more. |
Software and ecosystem | Native support for NVIDIA DOCA SDK to create applications that utilize BlueField hardware acceleration. Support for SDN, NVMe-oF, distributed NGFW, and micro-segmentation. |
Applications | Used in hyperscalers, cloud, HPC, 5G networks, telecommunications, AI acceleration, data storage and protection. |
Energy efficiency and performance | BlueField-3 is comparable in compute performance to a 12-core server CPU, while being more energy efficient and with less load on the host. BlueField-4 promises still significant growth. |
