Chunghwa Telecom accelerates next-Gen AIDC deployment to boost AI compute
The data center industry is undergoing its largest structural transformation in the past decade due to the rapid development of generative AI. As AI models drive growing demand for GPUs, high-speed connectivity, and high-density computing, data center requirements are evolving beyond traditional colocation services to encompass comprehensive upgrades in power supply, cooling, networking, and overall infrastructure architecture. At the recent DIGITIMES 2026 Enterprise Data Center Forum, Chunghwa Telecom Senior Engineer Hsueh Jen-Hao presented "Meeting the AI Challenge: The Evolution of Data Center Requirements and Infrastructure Upgrade Strategies," outlining Chunghwa Telecom's key strategies for responding to the AIDC (AI Data Center) trend and helping enterprises plan their AI computing capacity. Hsueh Jen-Hao noted that power demand per rack has surged from the traditional 2 kW to 5 kW range to 100 kW and even 200 kW. This underscores that the AI era is driving not merely an upgrade of data center equipment, but a paradigm shift across data center design, cooling architecture, energy management, and cross-border network connectivity. AI Servers Drive Higher AIDC Service StandardsHsueh Jen-Hao described AIDC as a "five-star hotel," illustrating the fundamental transformation in the nature of data center services. As AI servers are high-value, power-intensive, and highly sensitive to environmental conditions, data centers must not only operate around the clock without interruption, but also maintain stable temperature and humidity levels, power supply, and network quality, while adjusting environmental conditions in accordance with customers' SLA requirements.To meet the operating environment required by AI servers, Chunghwa Telecom is also upgrading the infrastructure of its data centers. Hsueh Jen-Hao noted that with a single rack often weighing more than 1,250 kilograms, data center floor loading requirements have increased significantly from 500 kg/m2 to 2,000-2,500 kg/m2. Structural specifications are now approaching those of heavy industrial facilities, redefining the conventional concept of an IT data center. Furthermore, the rapid rise in rack power consumption has pushed cooling requirements beyond the limits of traditional air-cooling systems. From Air to Liquid Cooling: Chunghwa Telecom Delivers Customized SolutionsAI computing has driven a dramatic increase in rack power density, from 30 kW-132 kW for NVIDIA H100 clusters to 140 kW per rack for the liquid-cooled GB200 NVL72 architecture. In response to this trend, traditional downflow air-conditioning systems and fan-wall cooling systems, which can support only up to approximately 20 kW, are gradually becoming unable to meet the cooling requirements of next-generation servers.To address the surge in cooling demand driven by AI computing, Chunghwa Telecom is actively introducing liquid-cooling technologies and tailoring solutions to individual customer requirements. From facility planning and design to project management, Chunghwa Telecom offers one-stop services to deliver the essential infrastructure needed for high-density AI computing, including cooling systems, power distribution, and power backup mechanisms. Through flexible modular designs, the data centers can be expanded alongside customers' business growth, satisfying the requirements for large-scale computing and data processing. Hsueh Jen-Hao noted that driven by both the thermal demands of AI servers and international regulations incorporating data center energy performance, liquid cooling solutions are gradually becoming a standard configuration for AIDCs. AIDC Ecosystem Expansion: Green Energy, All-Photonics Networks, and Submarine CablesIn response to the AI wave and the growing adoption of innovative applications, Chunghwa Telecom is not only enhancing cooling technologies within its data centers, but is also pursuing a comprehensive strategy spanning energy, networking, and submarine cable infrastructure. First, Chunghwa Telecom launched its Green Energy AIDC initiative in 2020. As of 2025, approximately 40% of the electricity consumed by its data centers came from renewable energy sources. The company aims to achieve its sustainability goal of powering data centers with 100% renewable electricity by 2030. Second, as cross-regional collaboration and data exchange continue to expand rapidly, high-bandwidth, low-latency connectivity has evolved from a competitive advantage into a fundamental requirement for data centers. To support the development and advancement of internet technologies, Chunghwa Telecom is promoting reference architectures, frameworks, and specifications for next-generation ICT infrastructure centered on all-photonics networks (APN), meeting the increasingly stringent requirements of innovative applications and AI computing for power efficiency, bandwidth, and latency. In addition, Chunghwa Telecom is Taiwan's first and currently only telecommunications operator to serve as a board member of the IOWN Global Forum.Hsueh Jen-Hao noted that the attractiveness of a data center location is directly proportional to the availability of local submarine cable resources. The continued growth of data centers in Hong Kong and Singapore, for example, is largely attributable to their roles as major international submarine cable hubs in Asia. To this end, Chunghwa Telecom has continued to invest in Taiwan's submarine cable infrastructure. On the international front, in addition to the completed SJC2 submarine cable system, the APRICOT system is also scheduled for completion in 2027. To enhance domestic network resilience, the Taiwan-Penghu-Kinmen-Matsu No. 4 submarine cable is expected to be completed in 2026. As these submarine cable projects come online, they will not only significantly strengthen Taiwan's international connectivity, but also provide a solid infrastructure foundation for cross-border AI computing and the deployment of international data centers.From floor loading capacity and liquid-cooling technologies to renewable energy initiatives, all-photonics networks, and submarine cables, Chunghwa Telecom's data center investments in recent years may appear to span different domains. However, they are all guided by the same strategic objective: systematically strengthening data center infrastructure to support enterprise AI adoption, ensure uninterrupted operations, and enhance Taiwan's competitiveness in the AI era.
