什么是数据处理中心(数据中心) (What Is A Data Processing Centre (Data Center))

A central data processing service is commonly used to fill a critical mission on computers and telematics. It generally includes environmental controls (air conditioning system to prevent against fire, etc.), Emergency power and redundant, and a high physical security.

中央数据处理服务通常用于完成计算机和远程信息处理的关键任务。 它通常包括环境控制(防止火灾的空调系统等)，紧急电源和冗余，以及高度的物理安全性。

A data processing center (data center) is as a place where various electronic equipment, especially computers and telecommunications equipment. As its name suggests, it serves primarily to process the information necessary for a business. For example, a bank may use such a center, giving him information about its customers while processing transactions thereof. In practice, almost all medium-sized companies use such a center. As for large companies, they often use dozens.

数据处理中心(数据中心)是放置各种电子设备，尤其是计算机和电信设备的地方。 顾名思义，它主要用于处理企业所需的信息。 例如，银行可以使用这样的中心，在处理其交易时向他提供有关其客户的信息。 实际上，几乎所有中型公司都使用这样的中心。 对于大型公司，它们经常使用数十个。

The databases are often critical to business operations as well as they are very sensitive to their protection. For this reason, these centers maintain high levels of safety and service in order to ensure the integrity and operation of equipment on site.

数据库通常对业务运营至关重要，并且对保护非常敏感。 因此，这些中心保持较高的安全性和服务水平，以确保现场设备的完整性和操作性。

Before the Internet bubble, millions of square meters to house such centers were built in the hope of seeing them held by servers. Since then, the concentration of centers has continued, with the development of specialized centers for which the most important challenges are the control of air conditioning and especially power consumption. This movement has been incorporated in the green computing and aims to reach treatment centers called ecological data for which special tools have appeared.

在互联网泡沫破灭之前，人们建造了数百万平方米的房屋来容纳这样的中心，希望看到它们被服务器占据。 自那时以来，随着专业中心的发展，中心的集中一直在继续，对它们而言，最重要的挑战是空调的控制，尤其是功耗。 这项运动已被纳入绿色计算，旨在到达出现了特殊工具的称为生态数据的治疗中心。

数据中心应用 (Data Center Applications)

The main tasks of the center are to provide a good network connection (internet, intranet, etc.) and high availability of the information system. Accordingly, it is possible to deploy different software applications for business-critical tasks of business customers. These applications include managers of databases, file servers and application servers.

该中心的主要任务是提供良好的网络连接(Internet，Intranet等)和信息系统的高可用性。 因此，可以为业务客户的关键业务任务部署不同的软件应用程序。 这些应用程序包括数据库，文件服务器和应用程序服务器的管理器。

数据中心—物理设施 (Data Center — Physical Facilities )

A data processing center (data center) can occupy one room, a floor or entire building. Included are 1U (nicknamed “pizza boxes”) or more, “U” corresponding to a unit height of 4.445 cm (1.75 inches), stacked in racks, which are arranged to form single rows, This allows to move easily among the servers, both front and rear. Some devices, mainframes, for example, are similar in size to these racks. They are often placed at their sides.

数据处理中心(数据中心)可以占用一个房间，一个楼层或整个建筑物。 包括大于等于1U(昵称“披萨盒”)的“ U”，对应于4.445厘米(1.75英寸)的单位高度，堆叠在机架中，排列成单行，这使得它们可以在服务器之间轻松移动，前后。 例如，某些设备(大型机)的尺寸类似于这些机架。 他们经常被放在一边。

中心的物理环境受到严格监督： (The physical environment of the centers is under strict supervision: )

•    Air conditioning to keep the room cool at all times, about 20 degrees Celsius. This maintenance is essential, since many electronic devices generate heat and will eventually fail when the temperature rises beyond a certain limit.

•空调可始终保持室内凉爽，大约20摄氏度。 维护是必不可少的，因为许多电子设备会产生热量，并且当温度超过一定限制时最终会发生故障。

•    Fairways are alternated between cold aisle (before the servers) and hot aisle (rear of servers) to prevent warm air from accumulating at the bottom of the piece and requires more cooling. The hot aisles can then be targeted more efficiently to remove heat.

•球道在冷通道(服务器之前)和热通道(服务器后部)之间交替，以防止热空气积聚在部件的底部，并需要更多的冷却。 然后可以更有效地将热通道作为目标以去除热量。

•    Recently, cold corridors have emerged in the data centers energy efficient. They consist of a sealed corridor which circulates cold air to the servers (sometimes the space between the machines is even blocked by caches to force fresh air inside them to borrow). Lower the temperature of the assembly allows for a greater density of servers.

•最近，节能高效的数据中心出现了冷通道。 它们由密封的走廊组成，该走廊将冷空气循环到服务器(有时，机器之间的空间甚至被高速缓存阻塞，迫使其中的新鲜空气借用)。 降低组件的温度可以增加服务器的密度。

•    The free cooling (air cooled) can limit the use coolers and thus reduce the energy bill. The free cooling is interesting that in settlements where the outside air is cold long enough during the year.

•自然冷却(风冷)会限制使用的冷却器，从而减少电费。 在一年中外部空气足够冷的地方，自然冷却是很有趣的。

•    The cooling can be supplemented by cooling water, which is 4000 times more efficient than air for heat conduction.

•冷却可以补充冷却水，其导热效率是空气的4000倍。

•    The standby power can be supplied via a UPS and a generator or via a rotating group (no-break) coupled to an accumulator kinetics.

•备用电源可以通过UPS和发电机或通过与蓄电池动力学耦合的旋转组(无间断)来提供。

•    In order to prevent a loss of power, all electrical components, including backup systems, are usually doubled. The servers are called essential increasingly fed by a system that uses two independent electric sources inside the center.

•为了防止断电，通常将所有电子组件(包括备用系统)加倍。 服务器被称为必不可少的服务器，越来越多地由中心内部使用两个独立电源的系统提供。

•    The centers usually have a raised floor 60 cm, made of removable panels. This space allows the free circulation of air, as it facilitates the wiring of power and data through different paths cable. However, data centers are no raised floor (above the feeding racks, to support easier for heavy elements mainframe (IBM z10, etc.).

•中心通常有一个高60厘米的活动地板，由可移动面板制成。 这个空间允许空气自由流通，因为它有助于通过不同路径的电缆进行电源和数据布线。 但是，数据中心没有活动地板(在送料架上方，以便更轻松地支撑重元素大型机(IBM z10等)。

•    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 cause a fire. In this way, it is possible to eliminate the source of a fire (sometimes, simply turn off one set of welding to eliminate the risk of fire). Second system is used to activate a set of activities if a fire occurs. These 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 use of Halon in such conditions. Some newer systems have emerged. Some use 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).

•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 essential to the operation of such centers. Physical access to these centers is restricted to authorized personnel, as well as video cameras to track people on the spot. Also, security guards ensure if the center is large or contains information considered essential.

•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。

The use of servers in a data center generates a co: heat is dissipated by the servers. Junk here, it is however desirable and valuable in other areas: home heating, offices or even Arboretum.

在数据中心中使用服务器会产生热量：服务器会散发热量。 但是，这里是垃圾，在其他领域是理想且有价值的：家庭供暖，办公室甚至植物园。

数据处理中心-网络 (Data processing center — Network)

Communications within a center are now almost exclusively by Internet protocol. It therefore contains routers, switches and other equipment that ensures the communication between the servers and the outside world. Redundancy is sometimes obtained by making use of multiple network devices of different brands.

现在，中心内的通信几乎完全是通过Internet协议进行的。 因此，它包含路由器，交换机和其他设备，可确保服务器与外界之间的通信。 有时可以通过使用不同品牌的多个网络设备来获得冗余。

Some servers are used to provide users of the company Intranet and Internet services from which they need: email, proxy, DNS, file, etc.

一些服务器用于向他们提供公司Intranet和Internet服务的用户，电子邮件，代理，DNS，文件等。

Of network security appliances are also present: firewall, VPN, intrusion detection systems, etc. as well as systems for monitoring the network and some applications.

还存在以下网络安全设备：防火墙，VPN，入侵检测系统等，以及用于监视网络和某些应用程序的系统。

数据中心—应用 (Data Center — Applications)

The main purpose of a data processing center (data center) is to run applications that process data essential to the functioning of a society. These applications can be designed and developed internally by the client company or a provider of management software company. It may be typical of ERP and CRM.

数据处理中心(数据中心)的主要目的是运行用于处理对社会运作至关重要的数据的应用程序。 这些应用程序可以由客户公司或管理软件公司的提供者内部设计和开发。 它可能是ERP和CRM的典型代表。

Often, these applications are spread across several computers, each running a portion of the task. The components in the data center are the most common systems management database, files servers, application servers, middleware.

通常，这些应用程序分布在多台计算机上，每台计算机都运行任务的一部分。 数据中心中的组件是最常见的系统管理数据库，文件服务器，应用程序服务器，中间件。
