The hottest new realm of Siemens Green Data Center

The "new" realm of Siemens' green data center

enters the gate of Siemens' data center computer room in Beijing, and the closed doors are displayed in front of us, which makes us feel a little confused: is this the data center

this is a data center built with the concept of subdivision design. Zhangzhiguo, the data center operation manager of Siemens IT solutions and services group, said that the subdivision design can realize the fine management and partition refrigeration of the data center, while ensuring the security of the data center. Subdivision design

the so-called subdivision design is to separate the various components of the machine room into multiple independent equipment functional areas, and place batteries, power distribution, it equipment, tape backup equipment, etc. in different rooms. Because different equipment is placed in different rooms, the administrator can easily manage all kinds of equipment in the machine room and carry out targeted refrigeration on different equipment, which greatly reduces the workload of managers. The construction area of Beijing Siemens data center phase I is about 500 square meters, an increase of 26.47% and 21.85% respectively over 2008 Meters, the management of such a medium-sized computer room only needs two administrators

the subdivision design ensures the security of the data center. Beijing Siemens data center has extremely strict access control and monitoring management measures. If someone wants to enter the data center, two managers of the data center must enter the correct password at the same time within 3 seconds before the door of the data center can be opened. In the data center, there is a T-shaped channel to separate different equipment functional areas. Each equipment function area is an independent room with access control. We have developed strict security management measures, allowing only two people to enter the data center at the same time at a time. Anyone's operation in the data center will be monitored. Even if someone leaves a bottle of mineral water in the data center, we can quickly find it. Zhang Zhiguo said

the subdivision design has obvious advantages in safety, manageability and fine refrigeration, but the one-time investment cost of this design method is high, which is not affordable for ordinary small and medium-sized computer room users. Zhang Zhiguo explained that although the one-time investment is large, from the perspective of long-term management, maintenance and refrigeration costs, the subdivision design is reasonable, and significantly enhances the comfort of the machine room. Enterprise trend: the gram weight of zetajet glass fiber nonwovens developed by German textilgruppe Hof company that can be used to produce automobile sound-absorbing panels ranges from 18 g/m2 to 350 g/m2

combination of three concepts

Beijing Siemens data center was put into use in 2008. In the past two years, Siemens has continuously optimized the data center, and its pue (energy efficiency) value has been reduced from the initial 2.07 to the current 1.72. At present, Beijing Siemens data center phase I project has been completed, which can host 100 racks and 630 servers. Traditional data centers are designed with more emphasis on reliability and security, ignoring energy efficiency. With the rapid expansion of business, the aging problem of data centers is becoming increasingly serious. Data centers with more than 4 years are currently facing severe challenges brought by the continuous increase of high-density IT equipment. The reason why Siemens continues to transform and optimize the data center is to improve the energy efficiency and scalability of the data center. Zhang Zhiguo said

Siemens brings it and building section 4 Combine rule technology and energy technology, and advocate the concept of sustainable it in the construction of data center. The concept runs through all aspects from design, safety, energy and water resources management to building engineering, communication and transportation. Li Jia, vice president of Siemens (China) it solutions and services group, said that Siemens' innovative data center solutions follow three design concepts, namely, maximizing server efficiency through virtualization technology, ensuring cost and use transparency through continuous measurement and energy management, and using automated processes and tools to ensure maximum labor savings

Beijing Siemens data center adopts Siemens' own unique bus bar system to replace the traditional row head cabinet, which not only improves the flexibility of the overall system and meets the needs of future expansion, but also greatly saves the space of IT equipment in the host room and improves the power density of the equipment. In terms of automatic intelligent management of the data center, the collector can transmit all the collected information of the data center to Siemens Building Management Software (BMS). Through the energy management, security, fire protection and other modules in the system, the data center can be comprehensively managed and monitored in real time. Beijing Siemens data center can carry out partition refrigeration according to the different requirements of different equipment on the environment, and provide different refrigeration methods. The underfloor air supply space in the data center is up to one meter. Except for strong electricity, all data cables are wired up, which can not only prevent the debris under the floor from blocking the flow of cold air, but also ensure that the cold air can be delivered to all areas of IT equipment in a balanced and effective manner, and reserve for the possible use of water cooling in the future. For example, if the express bag is handed over to consumers, it will tear and pollute the pipe space. Beijing Siemens data center adopts the strategy of phased construction and step-by-step investment, which can save 37% energy every year
