The convergence of liquid cooling and air cooling; more indirect evaporative cooling and less chilled water cooling GPU and NPU applications generate more high-density scenarios and liquid cooling systems will become more and more popular. Some storage and computing services, however, are still in low-density scenarios. To quickly adapt to uncertain IT service requirements in the future, the cooling solution must be compatible with the air-cooling system and liquid cooling system. In addition, the complex architecture of the chilled watercooling system hinders quick deployment and easy O&M. An indirect evaporative cooling system, with a modular architecture, will shorten the deployment time and simplifies O&M. In addition, by fully utilising the natural cooling resources, power consumption of the cooling system will be greatly reduced. In areas with a suitable climate, the chilled water system will gradually be replaced by indirect evaporative cooling system. 9. Dynamic linkage between bits and watts “ TO MEET THIS DEMAND, DATA CENTRES MUST SOLVE CONSTRUCTION CHALLENGES TO BUILD AT SPEED AND SCALE AND MANAGE ENERGY USAGE AND COSTS IN A SUSTAINABLE WAY. Reducing PUE doesn’t mean that the overall energy consumption of the data centre is optimal. Instead of focusing on the data centre energy facilities, the energy consumption of the data centre needs to be evaluated and optimised as a whole. Through full-stack innovation among facility, IT, chipsets, data and cloud, bits and watts will work collaboratively to achieve dynamic energy-saving and optimal energy efficiency of the entire system. 10. Trustworthiness architecture modularisation and equipment room modularisation, finally achieving full modularisation of the data centre. The full modular design will enable fast deployment, flexible capacity expansion, simple O&M and high energy efficiency. 7. Simplified power supply architecture. Lithium batteries becoming the norm The power supply and distribution system of a traditional data centre is complex and fragmented; it occupies a large footprint and it is difficult to locate faults. A simplified power supply architecture will reduce power conversion times, shorten the power supply distance and footprint, improve the space utilisation rate and enhance system energy efficiency. Compared with lead-acid batteries, lithium batteries have advantages in terms of footprint and service life. As the cost of lithium batteries decreases, lithium batteries will be widely used in data centres in the future. (Full modularisation of the data centre will enable fast deployment, flexible capacity expansion, simple O&M and high energy efficiency.) As the data centre facility becomes more intelligent, the network security threats will multiply. The data centre must have six features: resilience, security, privacy, safety, reliability and availability to prevent attacks and threats from environments and malicious personnel, including network intrusion threats. (Reducing PUE doesn’t mean that the overall energy consumption of the data centre is optimal. Instead of focusing on the data centre energy facilities, the energy consumption of the data centre needs to be evaluated and optimised as a whole.) • www.intelligentcio.com INTELLIGENTCIO 77
