How are AI data centers different from traditional data centers?
AI data centers and traditional data centers can be physically similar, as they contain hardware, servers, networking equipment, and storage systems.
The difference lies in their capabilities: Traditional data centers were built to support general computing tasks, while AI data centers are specifically designed for more sophisticated, time and resource-intensive workloads. Conventional data centers are simply not optimized for AI’s advanced tasks and necessary high-speed data transfer.
Here’s a closer look at their differences:
AI-optimized vs. traditional data centers
- Traditional data centers: Handle everyday computing needs such as web browsing, cloud services, email and enterprise app hosting, data storage and retrieval, and a variety of other relatively low-resource tasks. They can also support simpler AI applications, such as chatbots, that do not require intensive processing power or speed.
- AI data centers: Built to compute significant volumes of data and run complex algorithms, ML and AI tasks, including agentic AI workflows. They feature high-speed networking and low-latency interconnects for rapid scaling and data transfer to support AI apps and edge and internet of things (IoT) use cases.
Physical infrastructure
- Traditional data centers: Typically composed of standard networking architectures such as CPUs suitable for handling networking, apps, and storage.
- AI data centers: Feature more advanced graphics processing units (GPU) (popularized by chip manufacturer Nvidia), tensor processing units (TPUs) (developed by Google), and other specialized accelerators and equipment.
Storage and data management
- Traditional data centers: Generally, store data in more static cloud storage systems, databases, data lakes, and data lakehouses.
- AI data centers: Handle huge amounts of unstructured data including text, images, video, audio, and other files. They also incorporate high-performance tools including parallel file systems, multiple network servers, and NVMe solid state drives (SSDs).
Power consumption
- Traditional data centers: Require robust cooling systems such as air-based or raised floors, free cooling using outside air and water, and evaporative cooling. Methods depend on factors such as IT equipment density and energy efficiency/sustainability goals.
- AI data centers: GPUs, due to their high processing power, generate much more heat and require advanced techniques such as liquid cooling, direct-to-chip cooling, and immersion cooling.
Cost
- Traditional data centers: Use standard hardware and computing components that do take up a big chunk of IT budgets. Costs can be reduced with optimized components, processes, cloud resources, and diligence around energy use.
- AI data centers: Are often far more expensive due to high costs of GPUs, ultra-high-speed networking components, and specialized cooling requirements.
Ultimately, AI-optimized and traditional data centers have pivotal, yet distinct, roles in enterprise. A key difference is adaptability: The rapid evolution of AI requires advanced infrastructure with modular designs that can accommodate evolving chip architectures, power densities, and cooling methods.
Key components of AI-optimized data centers
AI-ready data centers have specific requirements when it comes to infrastructure. They must be able to perform high-performance computing (HPC) and process enormous datasets for training, inference, deployment, and ongoing operation of AI systems. This process is enabled by:
- AI accelerators: These specialized chips span hundreds, or even thousands, of servers working in tandem.
- Fast and reliable networking: Low latency and high-bandwidth connections between compute clusters and storage and data sources is a must. In some cases, bandwidth requirements can reach into the terabits per second (Tbps). Leading providers incorporate direct cloud connectivity, software-defined networking, and high-speed, redundant fiber connections to support performance. Technologies such as ethernet and InfiniBand, and optical interconnects can quickly transfer data between chips, servers, and storage.
- GPUs: Popularized by Nvidia and originally designed for rendering graphics in video games GPUs are electronic circuits that perform many calculations simultaneously, what’s known as parallel processing. This involves fragmenting complex tasks into smaller pieces that can be solved concurrently across multiple processors. Parallel processing makes GPUs fast, efficient, and scalable, optimizing neural networks and deep learning applications and reducing training and inference times.
- TPUs, NPUs and DPUs: AI-ready data centers increasingly incorporate more specialized accelerators specifically built for AI workloads. These include tensor processing Units (TPUs), neural processing units (NPUs), and data processing units (DPUs).
- TPUs speed up tensor computations, or multi-dimensional data structures, so that AI models can process complex data and perform calculations. They are extremely efficient at handling large-scale operations fundamental to training and running AI, and their high throughput and low latency make them ideal for AI and deep learning.
- NPUs mimic the neural pathways of the brain, allowing for processing of AI workloads in real time. They are optimized for parallel processing and offload AI tasks from CPUs and GPUs to optimize performance, reduce energy needs, and support faster AI workflows.
- DPUs offload and speed up networking, storage, and security functions, freeing up CPUs and GPUs to focus on AI tasks. DPUs often handle data compression, storage management, and encryption to help improve efficiency, security, and performance.
Advanced data center cooling systems
AI workloads produce a significant amount of heat, forcing a re-think of facility design, particularly when it comes to cooling. Energy-efficient techniques and advanced cooling systems are a must for AI-optimized data centers.
