Looking at the Data Center Construction from a New Regulation
The "Electronic Information System Computer Room Design Specification" (GB50174-2008) implemented on June 1, 2009 did not extend the previous "Electronic Computer Room Design Specification" or change to the data center design specification. Mr. Zhong Jinghua, the leader of the electronic information system computer room design specification preparation team and the deputy chief engineer of China Electronics Engineering Design and Research Institute, broke the differences in the new regulations in one word. "Compared with the" Electronic Computer Room Design Specification "issued before, the new regulations not only extend the coverage of the modern computer room construction name specification, but also compulsory requirements for the specific content of life safety, energy conservation and environmental protection in the construction of data centers."
The mandatory requirements of life safety, energy conservation and environmental protection in the new regulations mentioned by Zhong Jinghua are clearly stated in Circular 101 issued by the Ministry of Construction in 2009. "The five mandatory provisions in Article 6.3.2, 6.3.3, 8.3.4, 13.2.1, 13.3.1 of the" Electronic Information System Computer Room Design Specification "all involve life safety, energy conservation and environmental protection. At the same time The requirements of the new regulations are higher than the national preparation process. "Zhong Jinghua explained to reporters. According to the "Electronic Information System Computer Room Design Specification" reporter found these five mandatory measures:
Article 6.3.2 stipulates that the fire resistance level of the electronic information system computer room cannot be lower than level 2.
Article 6.3.3 stipulates that when the A- or B-level electronic information system room is located in other buildings, a partition wall with a fire resistance rating of not less than 2 hours shall be installed between the host room and other parts, and the doors on the partition wall shall be Use Class A fire door.
Article 8.3.4 stipulates that the metal enclosures, all kinds of metal pipes, metal wire ducts, metal structures of buildings in the equipment room of the electronic information system must be connected with equipotential and grounded.
Article 13.2.1 stipulates that the host room using a pipe network clean gas fire extinguishing system or a high-pressure water mist fire extinguishing system shall be equipped with two fire detectors at the same time, and the fire alarm system shall be linked with the fire extinguishing system.
Article 13.3.1 stipulates that the main room with a clean gas fire extinguishing system shall be equipped with special air breathing apparatus or oxygen breathing apparatus.
The above five articles all deal with personal and equipment safety provisions. In addition, the mandatory provisions are clearly explained in the description part of the specification.
New regulations call out data center intelligence
"The new regulations have put forward higher requirements for the construction of data centers. The traditional construction model adopted by enterprises in the past is bound to be insufficient in terms of safety, energy conservation and environmental protection. The demand for intelligent construction of data centers is rising. Construction trends. "Zhong Jinghua told reporters.
With the popularity of information technology, the growth of the number of IT equipment in data centers has accelerated. The demand for energy consumption in data centers is growing faster than in other fields, and companies are spending more and more on electricity costs each year. In the current energy consumption of the computer room, the main consumption comes from IT equipment energy consumption, cooling system energy consumption, power supply and lighting equipment energy consumption.
"The intelligent construction of the data center has the most obvious effect on energy saving and emission reduction, and it is also the most direct to reduce the maintenance cost of the enterprise computer room. The information director told reporters this way.
In terms of security, the intelligent data center can provide 7 * 24 hours of video surveillance. For the construction of enterprise computer rooms with wide distribution, large number, large number of maintenance personnel, and difficult management and monitoring, centralized management and unified monitoring can not only reduce the monitoring and maintenance costs of the computer room, but also improve the operation and maintenance quality goals.
The following problems will occur in the data center without monitoring and management:
1. Thefts of equipment in equipment rooms occur frequently. Alarms, monitoring, and records cannot be made for thefts, resulting in impunity for criminals.
2. The inspection process of maintenance personnel cannot be standardized and supervised. There is no objective record of when, who and how long to complete the maintenance work.
3. There is no access control security system in the computer room, and problems can not be discovered in time when there is no one on duty, which leads the security department to take a lot of additional responsibilities for this.
4. The power supply system is not monitored, power failure, abnormal power supply, the status of the communication power supply is not monitored, and the backup battery is damaged due to over-discharge after the power failure.
5. The air conditioner in the computer room is turned on all the year round, resulting in excessive electricity bills.
6. The environment is not monitored and flooding, fire, etc. cannot be dealt with in time ...
Whether it is due to security considerations or the green wave, the trend of intelligent, systematic and refined data center construction has become an industry consensus. "Compared with the previous concept of energy saving and emission reduction, the efforts of enterprises in energy saving are now changing from passive to active. The trend of system room energy saving towards systematization, intelligence and refinement is overwhelming." Siemens IT Solutions and Service Group Cheng Yingjun, the manager of the solution department, told reporters.
Data center building intelligence, the third eye is looking at you
Intelligent design is increasingly showing an important position in the construction of computer rooms. It focuses on the use of advanced equipment and software technology to monitor and manage the personnel and equipment in the data center, which is convenient for the operator to maintain the data center.
The data center should have a very good computer room environment, security assurance, network bandwidth, the number of hosts and the performance of the host, large storage data space, software environment, and excellent service performance. Therefore, how to build a data center with high manageability, high availability, high reliability and high scalability has become the focus of the intelligent building industry.
Security issues are the core elements of the data center. The aspects of data center security design include control means for personnel to enter the data center, alarms for abnormal conditions, daily monitoring systems and corresponding blocking means, reasonable layout of lighting systems, and recovery of corresponding disasters. , Are inseparable from the intelligent management system of the data center.
"Siemens data center centralized monitoring system has dispatch function, integrates IT service management, covers various advantages of conventional power environment monitoring system, and combines the alarm system and dispatch management system of the computer room to achieve a comprehensive closed loop of people and equipment Management. "Cheng Yingjun said.
In addition, the intelligentization of Siemens data center organically combines monitoring and operation and maintenance management to realize intelligent billing. At the same time follow the ITIL management process, especially to strengthen configuration management and change management, centralized in the database of the monitoring system.
"Siemens data center building intelligent solution not only conforms to the enterprise's energy-saving and low-carbon environmental protection concept, but also achieves 7 * 24-hour seamless video surveillance, eliminating the hidden dangers of enterprise data center security in the bud, just like the third eye To you. "Cheng Yingjun told reporters.
Intelligent scheme design of Siemens innovative data center
1. The layout of Siemens data center adopts subdivision design
1. Similar to the ship's cabin subdivision design concept, it improves the safety and reliability of the overall system; regardless of any fire or other abnormal conditions in any area, it will not be central to other areas, thereby minimizing local risks to the entire System hazards;
2. For the functions of different areas and the characteristics of the equipment, zone temperature control is carried out to achieve the effect of energy saving; (according to the different requirements of the power distribution room, battery room, assembly room, data tape backup room and IT host room, different temperatures are controlled humidity)
3. In accordance with the requirements of GB 50174 "Electronic Information System Computer Room Design Code", manned and unmanned areas should be arranged separately to avoid cross-flow of logistics and people.
2. Distribution circuit breaker of Siemens data center with monitoring function
1. The circuit breakers at all levels have monitoring functions, which can realize the centralized monitoring of the entire power system. Any abnormality in the working status of the circuit breaker can be promptly reflected to the monitoring system, so that maintenance and management personnel can accurately and quickly find and solve problems;
2. Real-time measurement and calculation of one of the core indicators of the data center: PUE value
3. Combined with the database support of the power environment monitoring system, historical data analysis including PUE value can be done
3. The design of its fire alarm system adopts VESDA system
1. Increase reliability, find dangers earlier and more accurately
2. Very early warning, VESDA can alarm 4-11 hours earlier than general fire alarm system
3. The sampling method is flexible, which can realize internal sampling in each fire protection zone: the use of capillaries extends into the fire protection zone to sample and detect the air, avoiding the influence of the detection effect due to obstruction of smoke diffusion, and ensuring that hidden fire hazards are discovered in the first place.
4. VESDA has a high-precision laser detector and has no requirements on the source and size of the particles to be measured. Its detection resolution is as high as 0.00075% obs / m, which is more than 1000 times higher than traditional spot detectors.
5. Strong anti-interference, the sampling pipe network of VESDA system usually uses PVC material, and there is no electromagnetic interference problem.
6. With network function, each device has RS485 interface, which is convenient for integration with power environment monitoring system.

4. Use an independent battery monitoring system to ensure that the internal resistance and voltage of each battery are monitored
1. Improve the overall reliability of the UPS system and timely discover the hidden troubles of battery failure, which directly affects the availability of UPS backup power supply. The unstable performance of the battery is a huge hidden danger of the power system, especially the stable operation of the UPS power system.
2. Guarantee the rationality of the operating parameters such as charging voltage, internal resistance and temperature of each single battery.
3. Accurately judge the deteriorated battery in the battery pack through the online test of the AC impedance of each single battery.
4. Judge and record the alarm status of the battery pack and individual cells.
5. Rely on power environment monitoring or other network transmission methods to realize remote monitoring of battery parameters.
6. During the check-up discharge test, it can record the voltage and impedance changes of the battery cells periodically to obtain the discharge curve of each battery cell.
The intelligentization of Siemens data center includes 7 * 24-hour real-time monitoring such as video monitoring system, power monitoring of computer room, temperature and humidity monitoring, monitoring of access control system, security and anti-destructive monitoring, fire and fire monitoring, and computer room water leakage monitoring. Realizing the dispatch management system through information means has guaranteed the enterprise's safety production goals. At the same time, monitoring and operation and maintenance management are organically combined, following the ITIL management process, especially strengthening configuration management and change management, and centralized into the database of the monitoring system. In case of emergencies, the system will feed back the information to the testing center as soon as possible to ensure that the maintenance personnel can arrive as soon as possible. "This greatly reduces the staff's response time to the data center crisis management and avoids the risk that the corporate security department will take more responsibility," Cheng Yingjun added.
The intelligentization of Siemens data centers not only guarantees safety, but also excels in energy conservation and environmental protection. The system adopts temperature and humidity monitoring. Temperature and humidity sensor probes must be installed in the main equipment working room of the equipment room to detect the temperature and humidity in real time, and display the temperature and humidity values ​​of each measuring point on the monitoring screen. When the detected value exceeds the upper and lower limit values ​​of temperature and humidity specified in each work area, a striking indicator flashes next to the corresponding data on the monitoring screen to remind the alarm of the overrun of the value. When the temperature and humidity of the equipment room meet the requirements, the system can be started in the energy-saving operation mode, so that the high power cost of the enterprise data center can be reduced, which can achieve the purpose of energy conservation and environmental protection while saving the operation and maintenance costs for the enterprise.
In recent years, the construction of data centers has become the focus of IT construction in various industries around the world. The annual growth rate of investment in domestic data center construction has exceeded 20%. Finance, manufacturing, government, energy, transportation, education, Internet and operators and other industries The construction of the data center is ongoing or has been completed. With the deepening of enterprise informatization and the widespread use of new technologies, traditional data centers are facing unprecedented challenges from all aspects. Safe, energy-saving and environmentally friendly data centers have become the industry consensus, and Siemens data center building intelligence is a successful solution under this general trend. "The intelligence of the data center is like the third eye looking at you. This eye brings not only safety and environmental protection, but also real business value." Cheng Yingjun explained.
Meat Tenderizer, or Meat Mallet, is a hand-powered tool to tenderize slabs of meat in cooking prep. Most commonly, meat tenderizer is a tool that resembles a hammer or mallet made of metal or wood with a short handle and dual heads. One face of the tool is usually flat while the other has rows of pyramid-shaped tenderizers. Tenderizing meat with the mallet softens the fibers, making the meat easier to chew and to digest. It is useful when preparing particularly tough cuts of steak, and works well when broiling or frying the meat.
