Introduce TMDC&TBLOCK technology largely deployed in Tencent infrastructure,and address backend logic to drive its definition and evolving path. Go through technical details over All-In-One micro-modular data center, including applicable environment, typical model of micro-module, power supply subsystem, cooling subsystem, structural subsystem, generic cabling subsystem, management and control subsystem, etc. Those subsystems and components in the micro-module can be prefabricated and qualified in the factory. Those components can be put into production after rapid onsite assembly and well scalability for dynamic volume adaptation.
