Because AI models handle more complex computations than traditional software, they need more power to run. To support this demand, organizations build specialized AI data centers, which provide the advanced hardware, robust power sources, efficient cooling, and fast networking to ensure reliability in large-scale AI systems.

What is an AI Data Center?

An AI data center is a facility designed to support the intense computational demands of AI systems. AI data centers typically include the following features:

• Specialized hardware: Because AI systems run multiple complex computations at once, they require support from clusters of graphics processing units (GPUs), tensor processing units (TPUs), and accelerators.
• Power feeds: AI data centers use bigger power feeds, high-density power racks, and advanced power management to support the intense power requirements of AI computations.
• Cooling: AI computations generate a substantial amount of heat. Advanced systems help keep temperatures at safe levels.
• High-speed networking: AI data centers rely on high-speed networking solutions to efficiently distribute computations across GPUs and accelerators.
• Large-scale data storage solutions: Tools like distributed file systems, flash storage, and high-bandwidth data pipelines allow data systems to access massive amounts of training data.

These components work together to enable AI systems to train on massive datasets, learn patterns, generate predictions, and make decisions at scale.

AI Data Centers vs Traditional Data Centers

As mentioned above, AI data centers require more power than traditional data centers. While traditional data centers are designed to support web services, storage, or general computing, AI data centers are built for intense parallel computing.

Compared to AI data centers, traditional data centers run on lower-density hardware, use less energy, and rely on standard cooling and networking.

Components of an AI Data Center

Data centers consist of multiple essential components. Hardware enables computations, power systems supply power, and cooling protects against wear and tear. Meanwhile, networking tools facilitate efficient hardware communication, while storage solutions provide fast access to training data.

Specialized Hardware

Modern AI models perform multiple intense computations simultaneously. To support the intensity of these computations, AI data centers employ specialized hardware. Unlike traditional data centers, which primarily use low-density CPUs, AI data centers also rely on large clusters of GPUs, TPUs, and other accelerators. The scale of these devices enables AI systems to process vaster amounts of complex data efficiently.

Each hardware component provides a different type of support.

• GPUs: As the name implies, graphics processing units were initially built to support graphics rendering. However, their structure makes them ideal for running multiple computations simultaneously. GPUs contain thousands of small cores, allowing AI systems to spread their workload across multiple physical processors at once. This makes them more efficient at complex computations than CPUs.
• TPUs: Similar to GPUs, TPUs are physical processors to run parallel operations. These specialized chips were designed by Google to manage AI workloads, namely tensor operations, which are the core calculations in neural networks. Their architecture allows them to perform millions of operations per second.
• AI accelerators: AI accelerators are a broad category of hardware, encompassing TPUs, field-programmable gate arrays (FPGAs), and other custom chips. They speed up AI workloads by offloading heavy operations from CPUs and GPUs, with a focus on neural network-specific operations, such as matrix multiplications, convolutions, or attention mechanisms. Their support enables data centers to run more complex models and process larger datasets without sacrificing efficiency.

Power Requirements

The computational demands of AI operations cause AI data centers to consume significantly more power than traditional data centers. GPUs and accelerators can draw hundreds of watts on their own, causing large data centers with vast amounts of hardware to expend tens of kilowatts.

Supplying this amount of power involves installing high-capacity feeds, designing dense racks, and deploying sophisticated power management systems.

• High-capacity power feeds: To keep AI systems running without disruption, AI data centers employ high-capacity power feeds. These supply the abundant power necessary to support dense racks of GPUs and accelerators. They are built to distribute power steadily without adding stress on the grid connection.
• High-density power racks: AI data centers store hardware components in highly dense racks to maximize the use of space. Because each rack runs demanding workloads, it places constant stress on the power infrastructure. Electrical designs must support steady power delivery to prevent disruptions or damage. Reinforced circuits, busways, and power distribution units designed for heavy loads typically help.
• Advanced power management: AI data centers use smart power management tools to track consumption, balance workloads, and optimize energy use. Without these systems, they struggle to manage power efficiently, which raises costs and reduces stability during intense bursts of activity.

Advanced Cooling

Because they are so power-intensive, AI computations generate a substantial amount of heat. If not properly controlled, they can damage hardware. Advanced cooling methods help AI data centers maintain safe temperatures for GPUs, TPUs, and accelerators. They remove heat efficiently while minimizing energy waste, which prevents performance throttling and extends the lifespan of critical hardware.

There are two main types of cooling methods.

• Liquid cooling: This method circulates liquid coolant directly over or near hot components. By absorbing excess heat, it keeps temperatures stable during intense workloads, decreases overheating risks, and enables racks to run at higher densities. Because liquid transfers heat more effectively than air, it keeps traditional cooling systems from working too hard, reducing overall energy consumption.
• Hot/cold aisle containment: This method separates the paths of warm and cool air to prevent air streams from mixing. In this setup, racks face each other to form a cold aisle where cool air enters and a hot aisle where warm air exits. This approach directs cold air where hardware needs it and moves warm air away efficiently, keeping cooling consistent and reducing waste.

High-Speed Networking

AI systems need to coordinate thousands of computations across disparate GPUs and processors. Models frequently exchange vast amounts of parameters, gradients, and intermediate results. Without a powerful network, nodes will be slow to communicate, delaying data delivery.

Most AI data centers rely on fast, low-latency networks to support inter-GPU communication. The most well-known solutions are InfiniBand, NVLink, and high-speed Ethernet.

• InfiniBand: This networking technology provides high-speed and low-latency, empowering processors to share parameters multiple times within seconds. Because it allows large clusters of GPUs to work as a single system, it reduces the time it takes to train complex models. It speeds communication up further by providing remote direct memory access, which allows one to read or write another’s memory.
• NVLink: This networking technology establishes fast connections between GPUs within the same server. It lets GPUs share data directly at higher velocities than traditional PCIe connections. This ability makes NVLink ideal for deep learning workloads that require exchanges of tensors and updates frequently and rapidly.
• High-speed Ethernet: This networking technology enables communication across broader data center networks. Modern Ethernet designs boast very high speeds, supporting the flexibility and scalability necessary to connect thousands of data center nodes.

Large-Scale Data Storage

AI models require access to massive volumes of training data. To grant GPUs and accelerators fast and reliable access to necessary data, AI data centers employ large-scale data storage solutions, such as distributed file systems, high-speed flash storage, and optimized data pipelines.

• Distributed file systems: These systems store data across multiple servers instead of relying on a single storage source. By distributing data, they allow AI workloads to access information from multiple locations, enabling multiple GPUs to read and write data simultaneously without the risk of bottlenecks. This keeps data moving smoothly even during complex computations.
• High-speed flash storage: These storage solutions accelerate the process of reading and writing data, and are much faster than traditional hard drives. This provides quick access to training data and model files, empowering AI systems to load large volumes of information efficiently.
• Optimized data pipelines: These solutions prepare, format, and deliver raw data from storage systems to compute hardware efficiently, accommodating the speeds GPUs and accelerators expect. They streamline each step to reduce delay, allowing hardware to continue computing instead of idling as it waits for new information. This prevents slowdowns and disruptions during training.

Specialized data storage solutions enable AI systems to scale seamlessly. They can expand to accommodate growth in AI workloads, supporting operations without slowing down. With efficient storage management, AI models can train on larger datasets and perform accurate computations at scale.

Types of AI Data Centers

There are two main types of AI data centers: hyperscale and colocation. Each differs in ownership, scale, and capacity.

Hyperscale

Hyperscale AI data centers are massive facilities typically owned by tech giants or cloud providers. They house thousands of servers, GPUs, TPUs, and accelerators to provide support for extremely large-scale AI workloads. Their equipment, including power infrastructures, cooling solutions, networking solutions, and storage systems, tends to be more advanced, enabling AI systems to handle enormous amounts of data and execute high volumes of operations.

Colocation

Unlike hyperscale AI data centers, which are typically owned by one company, colocation data centers are shared facilities. They provide rented space, power, and cooling for multiple organizations, who typically bring their own GPU, TPU, and accelerator clusters.

Colocation centers allow companies to access secure AI infrastructure and support without investing in their own AI data centers. Typically, they are less powerful than hyperscale facilities, but can support moderate to large AI workloads.
