VNET Group, Inc.: Huailai

The Huailai Data Centre, operated by VNET Group Inc., is located in the Huailai County region of Hebei Province, China — part of the broader Beijing-Tianjin-Hebei (Jing-Jin-Ji) data-centre corridor. It stands out as a next-generation facility purpose-built for high-density AI and large-model workloads, offering direct connectivity into the Beijing metro area with low latency. 

⚙️ Facility Highlights

• The site is described as a “Super Artificial Intelligence Data Center (AIDC) node” by VNET, designed for large-model training, inference and high-density GPU computing. 
• According to third-party reporting, the broader campus (including Huailai) has a gross floor area (~678,807 sq ft) capable of accommodating more than 5,700 high-density racks at full build-out. 
• Cooling and energy-efficiency: Indirect evaporative cooling (IDEC) systems are referenced for the campus — consuming up to 50% less energy versus traditional chilled-water systems. 
• Scalability: The facility supports phased delivery and modular build-out — reflecting VNET’s wholesale-scale strategy and modular data-centre design approach. 
• Supported services: Designed for wholesale colocation, AI/workload-dense deployments and highly-connected network infrastructure — aligning with VNET’s wholesale IDC business model. 

🔐 Security & Compliance

• While detailed specification sheet information specific to Huailai is limited in publicly-available sources, VNET’s data-centre operations emphasise high availability, secure lifecycle operations, and risk-mitigated infrastructure. 
• The campus builds to China’s “Class A” data-centre standard and is part of a larger “green-data-ecosystem” in the Huailai Technology Industrial Campus.
• Security of supply-chain, redundant power and cooling systems, and low-latency connectivity are embedded in the design and strategy.

🌐 Connectivity & Carrier Access

• Situated in Huailai within the Beijing-Tianjin-Hebei region, the data centre benefits from direct connectivity to the core Beijing network hub, enabling low-latency access and regional fibre-diversity.
• VNET is a major carrier-neutral data-centre provider across China (50+ facilities in 30+ cities) offering extensive inter-connect and wholesale options. 
• The wholesale solution emphasises integration with leading cloud, internet and high-performance compute clients — implying strong network/fibre availability at the Huailai site. 

💼 Who It Serves

• Hyperscale cloud providers, AI/ML and large-model training customers that require large-scale racks and GPU-dense environments.
• Enterprises and service providers needing high-density, future-proof compute with regional connectivity into Beijing and the northern China corridor.
• Network-centric operators and content providers looking for scalable wholesale colocation in the north-China data-centre cluster.
• Organisations focusing on green and efficient computing infrastructure, leveraging modular build-out and energy-efficient cooling technologies.
