In terms of technology trends, high density and greening are triggering changes in data center infrastructure. On the one hand, driven by high cost and high energy consumption, the power supply architecture of data centers has been gradually simplified; on the other hand, the expansion of business volume and the improvement of power density have promoted liquid cooling to become a new trend in data center cooling.

As a new cooling method, liquid cooling is emerging worldwide. Unlike traditional air cooling, liquid cooling directly guides the heat source through the liquid to take away heat, and does not need to be cooled indirectly through air circulation like air cooling, so it has higher heat dissipation efficiency, more energy saving and lower operating noise. At present, with the rise of artificial intelligence technology, the application scale of GPU and TPU servers is increasing, and liquid cooling applications are gradually infiltrating from supercomputing centers to data centers in various industries.
At the same time, the modular data center has also entered the stage of mass production and application, becoming a new mode of data center construction. The modular data center model was pioneered by an Internet company in my country, which successfully migrated the construction of the data center from the "construction site" to the "factory". Compared with the traditional data construction cycle of 2-3 years, the modular data center can be deployed within 40 days.

According to the statistics of the Open Data Center Committee (ODCC), by the end of 2017, the deployment of micro-module data centers has increased from 300 sets in 2013 to 4,500 sets, which is equivalent to more than 50,000 20A racks, and the pre-module data center has completed 9,100 sets. The deployment of one 40A whole cabinet is equivalent to 18,000 20A standard cabinets, and the modular data center has completed the deployment of about 70,000 standard racks, which can accommodate more than 1 million servers. The large-scale application of modular data centers has brought significant benefits. The survey shows that since the operation of the modular data center for 6 years, the performance of the modular data center has been stable, the average PUE has dropped by 0.2-0.4, and the operating cost has been reduced by 20%-40%.
Customization is also becoming the development direction of data center facilities and equipment. This trend is first manifested in the iterative innovation of self-designed whole cabinet servers to support new technologies and new applications. Secondly, the telecommunications industry explores deeply customized servers and is committed to promoting the reconstruction of telecommunications networks.

It is particularly worth mentioning that higher performance and speed have become the development trend of data center IT equipment technology, which is mainly reflected in three aspects: 1. GPU servers break through the efficiency bottleneck of CPU servers, and the computing speed is greatly improved; 2. Solid state The emergence of hard disks has changed the market pattern in which mechanical hard disks dominate the market. Third, the advancement of flash memory technology has helped solid-state disks break through capacity limitations, which is expected to drive down costs.
