Aiming at the large-scale construction needs of large data centers, the MDC single-row integration solution adopts a multi-cabinet collaborative linkage design on the basis of single-cabinet integration to realize the overall integration and large-scale deployment of power supply and distribution, refrigeration, monitoring and other systems. The solution arranges multiple functional cabinets in a regular manner to form a single-row module, and realizes the coordinated operation between cabinets through a unified bus and control system, ensuring the stable power supply and balanced refrigeration of the entire module. During the construction process, the MDC single-row module adopts the mode of factory prefabrication and on-site splicing, which can realize batch deployment and greatly shorten the construction cycle of large-scale data centers. At the same time, the single-row integrated design is convenient for realizing the standardized layout of the computer room, improving space utilization, and facilitating later partitioned operation and maintenance and management. When the data center business expands, the system can be expanded by adding new single-row modules without large-scale adjustment of the original system, which has good expandability. In addition, the MDC single-row solution is equipped with a unified centralized monitoring platform. Staff can real-time grasp the equipment operation status, energy consumption data and other information of the entire single-row module, realizing refined operation and maintenance. At present, the solution has been applied in many large cloud data centers, effectively improving the construction efficiency and operation management level of data centers, and providing strong support for the large-scale development of large data centers.
