Overview of AI Data Center
Server Room
The AI Data Center building is a low-cost, lightweight “Warehouse”-like structure, with the server room occupying the majority of its interior. The server room is 62ft. x 79ft., about the same size as a basketball court, and has a ceiling height of 20ft. The floor is made of concrete slab and has a load-bearing capacity of 2.84 psi.
Cooling Pods
Cooling pods are a “Spires” structure, originally designed by AIST, that packages racks for storing compute servers, water cooling piping, air conditioning units, power supply systems, network wiring, etc., to realize an ultra energy-efficient, ultra high-density data center. The cooling pods can provide 70 kW of cooling capacity per rack.
Currently, four cooling pods are installed in the server room, with a total of 144 racks available.
Cooling and Power Facilities
The AI data center building employs a free cooling system that uses only cooling towers to produce chilled water, achieving ultra-low power operation with an average annual PUE of less than 1.1. A cooling tower is a device that uses water evaporation to cool hot water; the AI Data Center building has 10 cooling towers with a cooling capacity of 5MW. It can produce up to 9,000 liters per minute of cooling water at 32°C even in summer. In addition, the building is also equipped with an active chiller (refrigerator) equivalent to 200 kW, for a total cooling capacity of more than 5.2 MW.
The AI data center building has a power capacity of 5.2 MW, commensurate with its cooling capacity.
