· They often have complex systems of prevention and extinguishing fires. The modern facilities are often equipped with two alarm systems. The first detects hot particles emitted by overheated components of the equipment, particles which often cau a fire. In this way, it is possible to eliminate the source of a fire (sometimes, simply turn off one t of welding to eliminate the risk of fire). Second system is ud to activate a t of activities if a fire occurs. The systems are also dedicated a portion of the data processing center (data center). Coupled with excellent fire doors and other devices for containment, it is possible to control the fire and extinguish it without affecting the rest of the building.
·他们通常具有复杂的预防和灭⽕系统。 现代化的设施通常配备两个警报系统。 ⾸先检测由设备过热的部件发出的热粒⼦，这些粒⼦经常引起⽕灾。 这样，可以消除⽕源(有时，只需关闭⼀组焊接以消除⽕灾危险)。 如果发⽣⽕灾，则使⽤第⼆个系统来激活⼀组活动。 这些系统还专⽤于数据处理中⼼(数据中⼼)的⼀部分。 再加上出⾊的防⽕门和其他⽤于围堵的装置，可以控制⽕势并灭⽕，⽽不会影响建筑物的其余部分。

The conventional systems for fire suppression are as harmful as the fire for electronic components. As a result, systems using Halon, an inert gas, have been developed. Removing oxygen from the room, he extinguished the fire. However, if a person is trapped inside such a room, she may die from asphyxiation. Many countries prohibit the u of Halon in such conditions. Some newer systems have emerged. Some u the Aragonite and FM-200, while others moved on the issue of fine particles of ultra-pure water (this water is not electrically conductive, which does not damage the electronic components).goacross
·传统的灭⽕系统与电⼦部件的⽕灾⼀样有害。 结果，已经开发了使⽤惰性⽓体哈龙的系统。 他从房间⾥除掉氧⽓，扑灭了⼤⽕。 但是，如果⼀个⼈被困在这样的房间内，可能会因窒息⽽死亡。 许多国家禁⽌在这种情况下使⽤哈龙。 出现了⼀些较新的系统。 有些使⽤Aragonite和FM-200，⽽另⼀些使⽤超纯⽔的细颗粒问题(这种⽔不导电，不会损坏电⼦组件)⽽引起关注。
· Security is also esntial to the operation of such centers. Physical access to the centers is restricted to authorized personnel, as well as video cameras to track people on the spot. Also, curity guards ensure if the center is large or contains information considered esntial.
·安全对于此类中⼼的运营也⾄关重要。 这些中⼼的访问仅限于授权⼈员以及⽤于现场跟踪⼈员的摄像机。 此外，保安⼈员还可以确保该中⼼是否宽敞或包含被认为必不可少的信息。
