1. Core Components (Left Panel)
The left side outlines the fundamental building blocks of a DPU, detailing how tasks are distributed across its hardware:
- Control Plane (Multi-core ARM CPU): Operates independently from the host server, running a localized OS and infrastructure management services.
- Data Path (Hardware Accelerators with FPGA): Utilizes specialized silicon to handle heavy, repetitive tasks like packet processing, cryptography, and data compression at wire-speed without latency.
- I/O Ports (Network Interfaces): Correction Note: The description text in your image here is accidentally duplicated from the “Data Path” section. Ideally, this should note the physical connections, such as high-bandwidth Ethernet or InfiniBand (100G/400G+), designed to ingest massive data center traffic.
- PCIe Gen 4/5/6 (Host Interface): Provides the high-bandwidth, low-latency bridge connecting the DPU to the host’s CPU and GPUs.
2. Key Use Cases (Right Panel)
The right side highlights how these hardware components translate into tangible infrastructure benefits:
- Network Offloading: Shifts complex network protocols (OVS, VxLAN, RoCE) away from the host CPU, reserving those critical compute cycles entirely for AI workloads.
- Storage Acceleration: Leverages NVMe-oF to disaggregate storage, allowing the server to access remote storage arrays with the same low latency and high throughput as local drives.
- Security Offloading: Enforces Zero Trust and micro-segmentation directly at the server edge by performing inline IPsec/TLS encryption and firewalling.
- Bare-Metal Isolation: Creates an “air-gapped” environment that physically separates tenant applications from infrastructure management, eliminating the need for management agents on the host OS.
Summary
This infographic perfectly illustrates how DPUs transform server architectures by offloading critical network, storage, and security tasks to specialized hardware. By isolating infrastructure management from core compute resources, DPUs maximize overall efficiency, making them an indispensable foundation for a high-performance AI Data Center Integrated Operations Platform.
