（通讯简报/Newsletter）

2024年3月22日，方舟科技CEO罗纲举携方舟科技（巴基斯坦）团队一行赴巴基斯坦首都发展局进行数据中心交流会，为巴基斯坦数据中心建设提供了宝贵的中国经验。

On March 22nd, 2024, Luo Gangju, CEO of Fangzhou Technology, and his Fangzhou Technology (Pakistan) team went to Pakistan Capital Development Authority for a data center exchange meeting, which provided valuable China experience for Pakistan's data center construction.

以下内容由方舟科技数据大数据技术总监吴彬先生主讲和分享：

The following contents were presented and shared by Mr. Wu Bin, the technical director of big data of Fangzhou Technology:

目前中国的有国家标准、行业标准，里面对数据中心的建设都有全系统的功能要求，其他国家的主要up time、TIA942、以及其他数据中心的基本要求标准。中国的标准是GB50174，主要是分了ABC三级。TIA942和Uptime Tier主要是分了四级。其中，C级和T1级基本是一致的，为基本型；B级和T2级基本是一致的，为冗余型。他们中间有一个T3级，基本上是对于中国标准B级的增强型，它是可并行维护型。A级和T4级基本是一致的，为容错型，主要以2N或者2(N+X)双系统同时运行为主。

The standard of China is GB50174, which is mainly divided into ABC three levels. TIA942 and Uptime Tier are mainly divided into four levels. Among them, Class C and T 1 are basically the same, which are basic type; Class B and T 2 are basically the same and are redundant type. Among them, there is a T3 level, which is basically an enhancement to our China standard Class B, and it can be maintained in parallel. Class A and T4 are basically the same, and they are fault-tolerant type, mainly with 2N or 2(N+X) dual systems running at the same time.

关于数据中心各个行业的对比。用数据中心应用的行业主要包括一些互联网巨头、新兴的互联网、各个政府部门还有基础电信运营商，主要是从它的机架数量、等级要求、功率密度、功能分区、新技术接受能力和带宽需求，还有网络架构以及PUE值即能耗值来进行分类。根据的经验，相对于各级政府部门，他们所用的自用型的数据中心来说，他们对于机架的数量，要求的不是很高，主要是自有自建等级要求，主要是按照国内或者是国际通用的标准就行。功率密度，基本上是中低功率，一般设计值的50%-70%之间在运行。

This is a comparison of various industries in the data center. The industries that use data center mainly include some Internet giants, emerging Internet, various government departments and basic telecom operators. We mainly classify them from its rack number, grade requirements, power density, functional partition, new technology acceptance and bandwidth requirements, and network architecture and PUE value, that is, energy consumption value. According to our experience, compared with the self-use data center used by government departments at all levels, their requirements for the number of racks are not very high, mainly their own self-built grade requirements, mainly in accordance with domestic or international standards. Power density, basically low power, is running between 50% and 70% of the general design value.

按照标准进行功能分区，根据各平台的功能需求、安全要求进行划分区域；对于新技术的接受程度相对要保守一点，因为他们是以安全可靠、稳定为主；对带宽的要求并不是很高，常规的专线就行了；网络架构比较复杂，因为各级政府部门对接的各个职能单位比较多，还有应用平台比较多，应用场景比较多，所以它的网络架构是比较复杂的。对于PUE值由于职能部门它是以可靠、稳定为主，对PUE的考核就没有那么高。

Divide the functions according to the standards, and divide the areas according to the functional requirements and safety requirements of each platform; The acceptance of new technologies should be relatively conservative, because they are mainly safe, reliable and stable; The requirement for bandwidth is not very high, so a regular dedicated line will do; The network architecture is more complicated, because there are many functional units connected by government departments at all levels, and more application platforms and scenarios, so its network architecture is more complicated. For PUE value, because it is mainly reliable and stable in functional departments, the assessment of PUE is not so high.

关于数据中心的规模，按照中国数据中心的经验来说，是分了小型数据中心、中型数据中心、大型数据和超大型数据中心，这里面就是以建筑面积、标准机架数量、服务器台数来进行的一个划分。当然这里面的划分，由于各个场景不同、还有各个使用单位的不同，建设规模为参考。

This is the scale of a data center. According to the experience of China data center, we are divided it into small data center, medium data center, large data center and super-large data center, which are divided by building area, number of standard racks and number of servers. Of course, the division here, due to different scenes and different users, is based on the construction scale.

关于数据中心的规划重点，因为数据中心它是一个多系统、多接口的、综合性的工程，在规划阶段就需要明确各个重要指标，第一个就是项目选址。项目选址就涉及到项目，它所需要的面积，它周边的环境就包括了市电环境、供水环境、安全环境，还有一些电磁兼容环境。交通主要就是涉及到数据中心，它的交通是否便利，包括人员上下班的一个情况，因为这里面涉及到人才规划和储备的问题。还有通信接入的情况是项目选址需要考虑的。

This is the planning focus of our data center, because it is a multi-system, multi-interface and comprehensive project. In the planning stage, we need to make clear all important indicators, the first one is the project site selection. The site selection of the project involves our project. The area it needs and its surrounding environment include commercial power environment, water supply environment, safety environment and some electromagnetic compatibility environments. Traffic is mainly related to our data center, and whether it is convenient, including the situation of our staff going to and from work, because it involves the problem of talent planning and reserve. There is also the situation of communication access, which needs to be considered in project site selection.

第二个就是业务预测，这个数据中心主要是来做什么业务类型。智慧城市关于有很多子系统，以哪些子系统为主，以及里面的业务化是以存储业务为主，还是以通用计算专用计算为主，这里面要做一个业务类型的划分。发展规划一个数据中心，从建成到全生命周期，可以长达数十年，怎么来进行综合的使用。

The second is business forecast, what kind of business our data center is mainly for. There are many subsystems under the smart city, which subsystems are the main ones, and whether the business inside is mainly based on storage business or general-purpose computing, which needs to be divided into business types. Developing and planning a data center, from completion to the whole life cycle, can last for decades. So we need to use it comprehensively.

第三个定位等级就涉及到是依照哪个标准、哪个规范里面的等级来进行建设，这里面涉及到它的安全、稳定、投资等因素。从建设等级确定了以后，还要确定承载业务，是以通用服务器为主，还是以专用的算力服务器（如人工智能）为主。

The third positioning level relates to which standard and the level in which specification we build, which involves its safety, stability, investment and other factors. After the construction level is determined, we also need to determine whether the service is mainly based on general servers or special computing servers (such as AI).

关于第四个就是机架需求，结合业务预测和等级定位来确定机架的数量、以及制冷系统、电气系统、综合布线系统的系统主要架构。最后一个就是关键技术里面主要是从可靠性、维护性、节能性和可发展性上面进行考虑。

The fourth one is rack demand, which combines business forecast and grade positioning to determine the number of racks, and the main system architecture of refrigeration system, electrical system and integrated wiring system. The last one is the key technology, which is mainly considered from the aspects of reliability, maintainability, energy saving and development.

关于数据中心的主要几个系统，直接从中国这边经验来看，主要包括建筑、结构、暖通、电气智能化和消防。

From the experience of China, the main systems of the data center below mainly include architecture, structure, heating and ventilation, electrical intelligence and fire protection.

第一个子系统是建筑子系统，那就涉及到整个房间的布局，门窗的这些处理，因为涉及到一些人员疏散，还有防火分区的问题结构。

The first subsystem is the building subsystem, which involves the layout of the whole room, the treatment of doors and windows, because it involves the evacuation of some people and the problem structure of fire partition.

第二个子系统是结构子系统，不同区域的建筑荷载值是不一样的，抗震加固根据各个地区的抗震等级、提升建筑和机电设备的抗震能力。

The sixth subsystem is fire fighting system, including gas fire fighting, water fire fighting, fire extinguisher and fire alarm. Among them, gas fire protection mainly protects electromechanical equipment rooms.

关于数据中心的主要建设的目标，目标主要是以四个目标为着力点。第一个承载能力、安全性能。它要可满足灵活承载各类等级的业务，提供七乘二十四小时的可用环境。第二个是可靠性和维护性，必须要能满足机房等级要求，可选增强性系统配置。

These are the main construction goals of the data center. We mainly have four goals. The first is bearing capacity and safety performance. It should be able to flexibly carry all kinds of services and provide a seven-by-twenty-four-hour available environment. The second is reliability and maintainability, which must meet the requirements of computer room level, and optional enhanced system configuration.

关于数据中心的能耗关键指标，目前中国数据中心发展很快，中国的数据能耗指标考核是相当严的，主要考核的是PUE和WUE，其他三个也是一个重要的参考。各个国家和地区，可以根据自己当地的情况来调整和制定关键指标。

These are the key indicators of data center energy consumption. Now China data center is developing rapidly, and China's data energy consumption indicators are very strict, mainly PUE and WUE, and the other three are also an important reference. Countries and regions can adjust and formulate key indicators according to their local conditions.

From the second floor to the fifth floor, the data center has been planned as a whole, and the main computer room area, auxiliary area, support area and administrative area have been planned reasonably. On the left are some renderings of the project case.

第二个子系统是结构子系统，主要就是对于每个区域的楼面荷载值的基本要求。荷载值的标准，可能各个国家各个标准它是有一定的差异的。左侧的指标是按照中国国家标准执行的。按照不同的功能区域确定不同的荷载值，可以有效减少土建成本。

The second subsystem is the structural subsystem, which is mainly the basic requirements for the floor load value of each area. The standard of load value may vary from country to country. The indicators on the left are implemented according to our national standards in China. Determining different load values according to different functional areas can effectively reduce civil engineering costs.

第三个子系统是暖通子系统。列举了目前主机房区域比较常用的空调系统，第一种类型是直膨式精密空调系统。它是由室内机和室外机组成、通过冷煤管进行循环。分为房间级精密空调和行间级精密空调。

The third subsystem is HVAC subsystem. We list the air conditioning systems commonly used in the main engine room area. The first type is the direct expansion precision air conditioning system. It is composed of an indoor unit and an outdoor unit and circulates through a cold coal pipe. Divided into room level precision air conditioning and inter-row level precision air conditioning.

直膨式精密空调具有安装方便、运行可靠、系统结构比较简单的优点，但能耗要偏高一点。直膨式精密空调主要用于中小型数据中心。

Direct expansion precision air conditioning has the advantages of convenient installation, reliable operation and simple system structure, but its energy consumption is a little higher. Direct expansion precision air conditioning is mainly used in small and medium-sized data center.

第二种类型是间接蒸发新风系统，是目前中国为了达到节能考核，而新开发的一种产品。直接通过室内室外新风换热，来完成室内的热量与室外的热量进行一个热交换。

The second type is indirect evaporative fresh air system, which is a newly developed product in China to achieve energy-saving assessment. Directly through the indoor and outdoor fresh air heat exchange, to complete a heat exchange between indoor heat and outdoor heat.

PPT右侧就是一个机房的模型，机房室内的热空气，通过回风吊顶回风到新风机组里内，完成降温后，再通过下送风送到机房里内机房里面去。

On the right is a model of a computer room. The hot air in the computer room is returned to the fresh air unit through the return air ceiling, and then sent to the computer room through the lower air supply after cooling.

间接性蒸发新风系统具有高效节能的优点，大部分区域可轻松达到PUE≤1.25的指标，缺点就是占室外空间比较大，而且支持的单机架功率不高，主要是以10kW以内的为主。

Indirect evaporative fresh air system has the advantages of high efficiency and energy saving, and most areas can easily reach PUE no more than 1.25. The disadvantage is that it occupies a large outdoor space, and the power of the supported single rack is not high, mainly within 10kW.

第三种类型是冷冻水空调系统。它主要是用于一些中大型数据中心。它的节能性也比较好，这边左边是一个标准的冷冻水系统的一个原理图，系统内配置有有冷却塔、循环水泵、换热器、冷水机组、蓄冷罐等。各管道为环形结构，可避免单点故障，可靠性高。

The third type is chilled water air conditioning system. It is mainly used in some medium and large data center. Its energy saving is relatively good. On the left here is a schematic diagram of a standard chilled water system, which is equipped with cooling tower, circulating water pump, heat exchanger, water chiller and cold storage tank. Each pipeline is annular structure, which can avoid single point failure and has high reliability.

冷冻水空调系统具有系统容量大、节能性好、制冷不间断的优点；大部分区域可轻松达到PUE≤1.35的指标。当市电停电时，可由蓄冷罐释冷来保障各机房设备制冷所需。

The chilled water air conditioning system has the advantages of large system capacity, good energy saving and uninterrupted refrigeration. Most areas can easily reach the index of PUE no more than 1.35. When the power supply fails, the cold storage tank can release the cold to ensure the cooling needs of the equipment in each computer room.

右侧是冷冻站、屋面的冷塔的安装情况。

On the right is the installation of refrigeration station and roof cooling tower.

第四种类型是液冷空调系统，随着人工智能、超级计算的发展，单机柜的功耗不断增加，现在单机柜的功耗最大的可以达到160kW。目前常用的是冷板式液冷空调系统，如左侧系统原理图，包括冷却塔、循环水泵、CDU换热单元、液冷服务器组成的系统，可直接使用外界自然冷源。右侧为冷板式液冷机柜。

The fourth type is liquid-cooled air conditioning system. With the development of AI and supercomputing, the power consumption of single cabinet is increasing, and now the maximum power consumption of single cabinet can reach 160 kilowatt. Now the commonly used cold plate liquid-cooled air conditioning system, such as the schematic diagram of the left system, includes a cooling tower, a circulating water pump, a CDU heat exchange unit and a liquid-cooled server, which can directly use the external natural cold source. On the right is the cold plate liquid cooling cabinet.

关于暖通系统的常用气流组织，第一种是风帽上送风/下回风，主要用于电力室、电池室等低发热量房间；第二种是风管上送风/下回风，主要用于面积小、负荷少的小型机房；第三种是地板下送风/上回风，主要用于单机柜功率不大于5kW的机房内，地板下为静压箱，送风距离较远；第四种是地板下送风/上回风+封闭冷通道，其优化了气流组织；第五种为行间空调+前送风/后回风，可封闭冷通道、热通道，气流组织好，可满足功率不大于几十kW机柜的制冷需求。

For commonly used airflow organization of HVAC system below, the first one is the upper air supply/lower return air of the hood, which is mainly used in low calorific value rooms such as power room and battery room; The second type is air supply/return air under the air duct, which is mainly used for small computer rooms with small area and less load; The third type is under-floor air supply/upper return air, which is mainly used in the machine room with a single cabinet power of not more than 5kW. The static pressure box is under the floor, and the air supply distance is far; The fourth type is under-floor air supply/upper return air+closed cold channel, which optimizes the airflow organization; The fifth type is inter-row air conditioning+front air supply/rear air return, which can close the cold channel and hot channel, and the airflow is well organized, which can meet the refrigeration demand of cabinets with power no more than tens of kW.

为了使得实际运行达到设计要求，经常在实际的设计和实施过程中会做一些CFD仿真。通过温度云可以知道每个服务器和每个机柜在运行过程中，它的温度变化情况，气流变化情况，这些都可以进行实时的仿真。

To make the actual operation meet the design requirements, some CFD simulations are often done in the actual design and implementation process. Through the temperature cloud, we can know the temperature change and airflow change of each server and each cabinet during operation, which can be simulated in real time.
