PRODUCT SPECIFICATION:

APPLICATIONS:

AI Inference Acceleration:

BlueField-2 offloads networking and data-path processing from the CPU, allowing GPUs and AI accelerators to focus fully on inference workloads. This ensures ultra-low latency and deterministic data movement, which is critical for real-time AI applications such as recommendation engines, speech recognition, computer vision, and autonomous systems. By reducing CPU intervention, it improves throughput, shortens response times, and enables faster scaling of AI inference services.

High-Performance Edge Analytics:

In edge deployments, BlueField-2 accelerates local data processing, reducing the need to transfer large datasets to central servers. This makes it ideal for IoT networks, industrial automation, smart factories, and smart-city applications, where timely decision-making and low-latency analytics are crucial. By handling packet processing, encryption, and storage acceleration at the edge, the DPU optimises network bandwidth and accelerates insights.

Network Function Virtualisation (NFV):

BlueField-2 enhances telecom and enterprise NFV deployments by offloading packet processing, encapsulation, and traffic management to hardware. This reduces CPU overhead and ensures high-throughput virtual networking functions, including firewalls, routers, and load balancers. The DPU’s programmable datapath allows operators to deploy VNFs at scale while maintaining consistent performance, deterministic latency, and reliability.

Cybersecurity & Threat Mitigation:

BlueField-2 strengthens network security with hardware-accelerated firewalling, deep packet inspection, and encrypted transport. It can detect and filter malicious traffic inline without impacting application performance, making it ideal for financial institutions, cloud providers, and enterprise networks where security and performance must coexist. Its deterministic traffic control ensures predictable network behaviour even under attack scenarios.

High-Density Multi-Tenant Data Centers:

BlueField-2 ensures reliable and predictable networking in multi-tenant data centers by isolating workloads, enforcing tenant-specific policies, and optimising bandwidth allocation. It supports high-density server environments, enabling secure and efficient operation for co-located workloads. This is especially valuable for cloud providers, managed services, and enterprise campuses requiring consistent QoS, low-latency communication, and traffic prioritisation across multiple tenants.

ADVANCED FEATURES

• Ultra-Low Latency Networking: Hardware-accelerated RoCEv2, congestion-aware transport, and deterministic packet scheduling for high-performance GPU and AI clusters.
  
• GPUDirect RDMA & Storage: Direct GPU-to-GPU and GPU-to-storage data movement, bypassing the CPU to reduce latency and improve throughput.
  
• Programmable Datapath: DOCA-compatible cores enable custom SDN, NFV, and storage offloads, allowing network and security functions to run directly on the DPU.
  
• Hardware Security Offload: Secure boot, line-rate encryption, ACL enforcement, firewall acceleration, and packet inspection without impacting CPU performance.
