Many businesses and organizations around the world depend on mission-critical, enterprise storage systems to provide super-high availability and predictable high performance. Performance, scalability, and cost of ownership are all extremely important, especially when it comes to resiliency and power, and space efficiency. The ever-increasing amount of microservices to support containerized and virtualized apps spread across data centers is especially taxing to the CPUs. NVIDIA BlueField is a family of data processing units that combines general-purpose CPUs with field-programmable gate arrays (FPGAs) to optimize data center applications, including network security. The DPU is used to offload, accelerate, and secure data-center infrastructure services, so that CPUs and GPUs are more available to focus on running and processing large volumes of other workloads, like AI and other data center applications.

Advantages of Data Processing Units (DPU)

The NVIDIA components provide hardware offloads for software-defined storage, networking, security, and management workloads, allowing for maximum performance. DPUs reduce networking demands on CPUs and increased performance on those jobs. The accelerator also delivers superior performance, security, and reduced TCO for cloud computing platforms, enabling organizations to efficiently build and operate virtualized, containerized, and bare-metal infrastructures at a massive scale.

Accelerating Network Security

Here are some ways in which DPUs can accelerate network security:

  • SmartNIC Functionality: BlueField DPU has a built-in SmartNIC (network interface card) that offloads network processing tasks from the host CPU which in turn, frees up the CPU to perform other tasks and thus improves overall system performance. The SmartNIC also includes hardware acceleration for network security tasks such as encryption, decryption, and packet inspection.
  • Hardware Security: BlueField DPU provides hardware-based isolation between workloads, which helps prevent firmware-level malware or side-channel attacks.
  • Programmable FPGA: BlueField DPU includes a programmable FPGA that can be customized to accelerate specific network security tasks. This can include offloading encryption, decryption, compression, or decompression tasks from the CPU, or performing specialized packet inspection.
  • Container Support: BlueField DPU supports containerization, enabling network security functions to be deployed as microservices, allowing security functions to be dynamically scaled and easily moved between servers.
  • Software Ecosystem: NVIDIA provides a range of software tools and libraries that enable developers to build and deploy network security applications. This includes libraries for encryption, decryption, and compression, as well as frameworks for machine learning-based security applications.


Modern applications, including AI, continue to generate massive amounts of data and processing, and that data is consuming CPU cycles and performance. NVIDIA BlueField DPU provides a range of hardware and software features that can accelerate network security tasks, improve overall system performance, and enable more flexible and scalable security architectures.
