High-density servers are commonly used, designed to support multiple accelerators per node and often equipped with specialized cooling and power delivery systems.

 

Most AI data centers employ heterogeneous computing, combining CPUs, GPUs, and accelerators to balance flexibility and performance.

 

High-performance networking is another essential component.

 

AI workloads require constant data exchange between compute nodes, making low-latency interconnects such as InfiniBand and high-speed Ethernet critical.

 

High bandwidth is necessary, with AI training clusters often requiring hundreds of gigabits per second per node.

 

Network architectures are also designed to scale efficiently, supporting thousands of nodes without performance degradation.

 

Storage systems form the data foundation of AI operations.

 

High-throughput storage solutions such as NVMe and parallel file systems are used to ensure data can be delivered to accelerators without delay.

 

Large datasets used for training and analytics are often stored in scalable object storage systems or centralized data lakes.

 

Most AI data centers implement tiered storage architectures to balance performance, cost, and capacity.

 

Power infrastructure is a critical design consideration.

 

AI data centers require high-capacity power delivery systems capable of supporting extreme power densities.
