Distributed power system DPS solutions in data centers. The deployment of distributed power supply DPS system products in the data center eliminates the need to plan power distribution rooms and UPS battery rooms, effectively improving the space utilization of the computer room and meeting customers' requirements for computer room resources and future expansion. Distributed power system products, integrated design of power supply unit + lithium battery module, dispersedly deployed in each IT cabinet; achieving rapid design, rapid supply and rapid installation, saving project construction cycle.

　　Data center development history

　　1. In 1970, the first-generation data center large computer room had low computing and power density, mainly carried scientific calculations and was completely integrated with the laboratory;

　　2. In 1990, the second-generation data center tower server room had lower computing and power density, mainly carried business applications, and had independent space;

　　3. In the 2000s, the third-generation data center rack-mounted servers had higher computing and power densities, carried applications, data services and Internet applications, and had dedicated buildings;

　　4. In the 2010s, the fourth-generation data center rack-mounted servers and high-performance computers have high computing and power densities, carrying big data, cloud computing and Internet of Things services and decoupling them from buildings.

　　The introduction of the distributed power system DPS has improved the reliability and service life of the data center power supply system, reduced the weight of the equipment, and improved the space utilization of the computer room. The advantages of distributed power system DPS are as follows

　　① Save the space in the computer room, eliminating the need for a UPS room and battery room; increase the utilization rate of the computer room space by more than 30%;

　　② Reduce the load-bearing of the computer room, the weight of the power supply is equivalent to that of IT equipment; the floor load-bearing requirements are low; reduce construction costs;

　　③Flexible on-demand configuration, modular design, and on-demand deployment; early design can be put online quickly; later expansion is simple;

　　④ Reduce operating costs, hot-swappable, easy to maintain; the system can dynamically adjust the load rate; the energy saving effect is good.

　　Typical application scenarios of distributed power system DPS

　　Telecom DC cabin: rapid and flexible deployment of 5G bearer network

　　Improve space utilization: deploy more than 30% more IT cabinets than traditional centralized + lead-acid batteries

　　Reduce TCO: invest in installments, deploy on demand, and ensure asset depreciation

　　Computer room renovation: only 6KN/m2 floor load-bearing is needed to meet deployment needs

　　Microgrid data center: Microgrid data center networking

　　Compliance: Backup source equipment and powered equipment are in the same space

　　Using the micro-module solution, the distributed power system DPS is deployed in IT cabinets, and 7 micro-modules are constructed, with a total of 232 IT cabinets deployed. The height of the cabinet is 48U, and the space delivered to customers is 42U. High priority uses the dual-channel distributed power supply system DPS for power supply, general priority and low priority use one mains power and one DPS for power supply; if the mains power is interrupted, the business system will be shut down safely in order of priority; when one or more DPSs fail At this time, power can be dispatched from the energy pool to supply power to the load carried by the faulty equipment.

　　The entire data center adopts the distributed power supply DPS system solution, which is constructed and deployed in phases to simplify the design, reduce the installation and deployment cycle and complexity, and at the same time eliminate the configuration of battery rooms and power distribution rooms to maximize the optimization of the computer room structure.
