The construction of data center migration faces many challenges. Power, refrigeration, safety and site are only one of the challenges of data center site selection and construction. However, in recent years, frequent earthquakes all over the world have brought severe challenges to the construction and operation of data centers.

Earthquakes have occurred in major developed countries, including the United States, Japan, Italy and the United kingdom. Companies that build new data centers and operate existing data centers have to think in a new way how to protect data centers, and data centers need to respond effectively to sudden earthquakes and unpredictable seismic forces. The major economic markets in the world exist in varying degrees of seismically active regions, such as California in the United States, Tokyo in Japan, and Rome in Italy.
Now, the construction technology continues to develop, to deal with the building materials for the construction of bending and rocking, let the building to deal with earthquake force is more flexible, and all kinds of infrastructure construction so that the building can transfer and eliminate the impact of the earthquake. The focus of these technologies is to make the building withstand a certain degree of vibration and vibration, to maintain the integrity of the building, to ensure the safety of personnel, but not very good protection of precision electronic equipment running normally.
Construction of data centers in areas with high earthquake or vibration risk requires different construction methods. It requires not only the integrity of the building, the safety of the personnel, but also the equipment on the rack to avoid damage and maintain normal use during the earthquake.
Understanding earthquakes
Earthquakes are vibrations or tremors produced by crustal movements, which are sudden movements of plates and then rebound. The earthquake vibration level from the minor to the earth trembled and the mountains swayed the catastrophic destruction of the earth's surface topography, may change, or even appear cliff huge cracks. In addition, this kind of crustal activity will occur frequently at sea, resulting in abnormal phenomena such as tsunamis. For example, when building a new data center in Japan, all these factors must be taken into account, while thinking about how to build buildings at the physical level.
Colt company in Chiba county about 30 km from Tokyo Japan the inzai construction of a data center. In view of the importance of the Tokyo market in the global economy, the data center needs to the city and the suburbs, can provide important services for users, and the choice of construction in inzai reached a good balance. Inzai near Tokyo, but away from the crowded city center, can be used as the redundant data center construction site. Data center operators generally understand that data centers will be faced with the possibility of earthquakes, thereby designing and building new data centers that are finer and more resilient.
In Japan, inzai data center construction
The lateral force to the building structure better earthquake resistant way is to the wall, floor, roof together, forming a super structure, and the infrastructure as isolated substructure, which is the basic premise of the construction of the new data center. However, in order to eliminate the shock and ensure that the equipment is as safe as the staff, it is also necessary to consider the geographical location of the building.
The Inzai 2 data center at Colt uses the latest construction technology to eliminate and reduce the effects of earthquake activity in the region. The superstructure sits atop a large mount of shock absorbers and Teflon sliders. The isolated shock absorbers, which can carry 125 tons of weight per square meter, can isolate the entire building from seismic forces and allow substructures and superstructures to move independently of each other. As a result, most of the seismic shocks and energy dissipation of the quilt structure are reduced and the influence on the superstructure is reduced.
The base of the seismic isolator can effectively allow the upper part of the building to sway, rather than building the building directly on the ground. As a result, the impact of vibrations is significantly reduced, protecting buildings, customer hardware and field personnel. By reducing the vibrations, a IT device in the hard disk drive can not be damaged or write error, blade server data center and other card, and fan and other cooling equipment will not be affected by the shock.
The Inzai 2 data center is more resilient, reliable, and scalable, ensuring long-term reliability and data protection. The final result of the test is that the maximum loss (PML) of the data center is less than 3%.
Although Japan is earthquake prone countries, but the western geographical location is very suitable for the construction of data center facilities. This is because it is located above sea level, and adjacent to the major populated areas such as Tokyo, as well as Japan's international channel Narita airport. Its geographical location also minimize the risk of external environment, such as earthquake triggered tsunamis.
It is worth noting that although earthquakes are a concern for data center builders, this is only one of the considerations in ensuring that data centers are protected and resilient as much as possible. For example, in the data center location, it is also necessary to consider whether the geographical location is based on the route of the flight, and the local substation can provide enough power and other factors.
