Why Do We Need AI Data Centres?

In the era of the digital economy, AI is penetrating into various fields at an unprecedented speed. From intelligent customer service and autonomous driving to medical imaging diagnosis, the application scenarios of AI are constantly expanding. Behind these complex applications, the demands for massive data processing and model training are growing exponentially. Traditional data centers have become difficult to meet the stringent requirements of AI applications in terms of computing power, storage, and energy efficiency.​

AI data centers have emerged as the times require. They are specifically designed for AI loads and can provide powerful parallel computing capabilities to meet the needs of rapid processing of massive data in deep learning model training.

Taking the training of natural language processing models as an example, an ordinary data center may take several weeks to complete the training. However, relying on its customized hardware architecture and optimized software algorithms, an AI data center can shorten the training time to several days or even less.

At the same time, AI data centers can also achieve dynamic allocation of resources, improve resource utilization, reduce operating costs, and provide solid support for the implementation and development of AI technology.

The Core Subsystems of an AI Data Centre Infrastructure?

● Computing Subsystem

The computing subsystem leverages GPUs and TPUs. Compared with CPUs, GPUs and TPUs have strong parallel computing capabilities and can process massive amounts of data simultaneously, significantly accelerating the training and inference of deep learning models. In addition, the computing subsystem also includes high-performance servers, which are interconnected through high-speed networks to form a computing cluster to meet the computing power requirements of AI applications.

● Storage Subsystem

A distributed-storage architecture tiers hot and cold data across SSDs and HDDs: SSDs deliver low-latency access for frequently used data, while HDDs provide cost-effective capacity for infrequently accessed information. Built-in redundancy and automated backups ensure data integrity and guard against loss.

● Network Subsystem

Using InfiniBand and 25/100 GbE, the network subsystem delivers low-latency, high-bandwidth links between all components—minimizing communication delays in distributed training. An intelligent traffic-management layer dynamically allocates bandwidth to maintain service quality for critical workloads.

● Power Supply and Cooling Subsystem

In densely packed AI facilities, efficient power supply and distribution systems ensure stable and reliable electricity supply, keeping IT equipment running smoothly. Meanwhile, advanced cooling system swiftly dissipate heat, preventing localized overheating that could lead to equipment failures.

How to Build an AI Data Center: A Step-By-Step Guide

How to build a data center? The step-by-step guide is as follows:

● Requirement Analysis and Planning

Before building an AI data center, you first need to clarify the application scenarios and business requirements, estimate the data growth scale and computing power requirements in the next few years. Meanwhile, select a suitable geographical location for the data center.

● Hardware Selection and Procurement

Based on the results of the requirement analysis, select and purchase computing equipment, storage equipment, network equipment, and power supply and cooling equipment. Performance and cost need to be taken into consideration.

● Infrastructure Construction

Carry out infrastructure construction, including the construction of computer rooms with high standards, the establishment of the power supply system, reasonable cabling, and reserving space for equipment, among other tasks.

● Software System Deployment

After the hardware infrastructure is set up, the corresponding software systems need to be deployed. This includes operating systems, virtualization platforms, AI frameworks, and management software, among others.

● Testing and Optimization

After construction is completed, an AI data center must undergo comprehensive testing to verify its readiness. This process should encompass hardware stability checks, software-system compatibility tests, network-performance measurements, energy-efficiency monitoring, and stress testing under simulated real-world scenarios. Each round of testing informs targeted adjustments and optimizations—whether updating firmware, tuning software stacks, reconfiguring network topologies, or recalibrating cooling systems—to ensure the facility operates at peak efficiency and reliability.

When selecting a service provider for your AI data center, it’s wise to partner with a proven, trustworthy leader such as Huawei. With operations spanning more than 170 countries and regions and over 1,000 large-scale data-center deployments, Huawei brings unmatched expertise to the table.
