Some tips on Integrated Wiring and smart energy-saving infrastructure

Data center construction at home and abroad, energy saving and Differentiation

At present, due to differences in standards and requirements, the construction of data centers at home and abroad is also different, especially for energy consumption and electricity charges. Why is the PUE value of foreign data centers close to 1, is the PUE of a common data center in China between 2.2 and 3? Where is the problem?

Ms. Chen LAN, sales director of the Greater China region of the U.S. company, said that this situation has a lot to do with the design plan of the data center. Many domestic data center design plans will ask foreign experts to refer to international standards for design specifications. Although they want to learn from some successful experiences of foreign data centers, however, to some extent, it also reflects that many of our domestic design concepts are less forward-looking than those in foreign countries-this puts forward new requirements for managers of our domestic data center operators, we recommend that you be proactive in design planning, not only in hardware investment, but also in software management.

WU Jian, Technical Manager of the enterprise solution Greater China region, pointed out that the energy consumption of data centers is a very common problem, and everyone has been concerned about and exploring corresponding energy-saving measures, one of the biggest differences between domestic and foreign data centers is in design and management. The design is not optimized enough, and the experience is not rich enough because of lack of talent. We can spend a lot of money to buy the best switch and the best distribution facilities, however, we do not want to spend money to form a management process, so that dedicated people can manage the data center and implement software management. We should use the process to manage it, not simply relying on people, this is also a concept of intelligent management process management.

Integrated Wiring and green energy saving

What is the relationship between integrated wiring and green energy saving? How can this problem be reflected? WU Jian said that there is still a relationship between the design and management, and the design must be forward-looking, because only forward-looking can save energy; management must also be intelligent, saving space is energy-saving and refined management, using software to manage data center infrastructure aims to save energy.

WU Jian told reporters that if the design is poor, half of the work will be withdrawn, or after the design is completed, it will be used to find that the transformation and upgrade are required. This material is a waste, time is also a waste. You are constantly upgrading and making another adjustment. This is not green or environmentally friendly, so it is very important to be forward-looking. What is the biggest bottom line of foresight? When selecting materials, when selecting copper cables, optical cables, and cabinets, you must consider what future applications are. If you don't think of it, you will certainly be subject to future restrictions. The most typical example of a forward-looking green energy-saving scenario is that if a link, for example, is a 10 Gigabit requirement and is only designed to 1 Gigabit, it will be necessary in the future, we think it is the same to replace 10 thousand m with 10g? 10 Gigabit ports are equal to 10 Gigabit ports, but 10 Gigabit ports are used to replace 10 thousand Gigabit ports. Do you think that the interfaces with 10 Gigabit ports are more energy-efficient? Therefore, replacing multiple low-speed interfaces with one high-speed interface is an energy-saving bottom line. This is also a forward-looking concept.

In fact,The most primitive and effective way to save energy in data centers is to save energy in cooling.What kind of cooling method is used to save cooling energy, which is also closely related to wiring. The air supply duct space can be provided, rather than the cable blocking, affecting the air supply.

When considering green and energy-saving, we need to manage how to reduce the energy consumption of all related equipment, including equipment rooms and IT equipment. If all your facilities are running on a daily basis, this will not save energy. Can we find a way to close them when we don't need them? For example, some data centers have low location temperatures and some have high location temperatures. For extensive management, when the temperature is high, the cold volume of the entire data center will be increased to bring down this hot spot; refined management is to know the location of the hotspot. cooling the hotspot separately will not make it meaningless for cooling other regions. This is energy-saving. How do you know where the temperature is high, where the hot spot is, and what cold air is called to cool the hot spot? This relies on intelligence, sensors, and integrated wiring.

Integrated Wiring is the most important aspect of connecting these sensors and then calling the entire data center resources through software. The software iTRACS acquired by the company is for Data Center Infrastructure Management (DCIM management ). DCIM is not clearly defined, but the main significance of DCIM is to use a software to manage all data centers, with the aim of saving energy. Intelligence is an important means to save energy.

In terms of Integrated Wiring and green energy saving, in addition to planning and design, we must be proactive, take into account the cooling and air supply of the data center, and consider intelligent management. In the future, we can also consider LED lights as a means of energy saving, the use of multimode optical fiber is also available. These five aspects are closely related to integrated wiring. If they are well designed, some intelligent technologies are used, LED lights are used, and the cable optimization problem of air supply is also taken into account, when some high-speed links are used properly, the overall energy saving of a data center can be reduced to at least 40%. This is the result of the best practice.
