3. What is a data center 01

4. What is a data center data center ( DataCenter ) It usually refers to the centralized processing, storage, transmission, exchange, and management of information in a physical space. Computer equipment, server equipment, network equipment, storage equipment, etc. are usually considered to be key equipment in the network core computer room.. 　　 The essentialEnvironmental factors required for equipment operation, such as power supply systems, refrigeration systems, cabinet systems, fire protection systems, monitoring systems, etc. are usually considered critical physical infrastructure data center concept

5. What is a data center Refrigeration, ventilation, humidity and other needs HVAC major Electricity supply and security Electrical engineering Fire safety configuration … Fire protection major information transmission channel Integrated wiring installprevention system, power environment monitoring system, etc. Weak current major Functional area division, building structure, airtightness and other requirements Decoration Major majors in data center

6. Terminology 02

7. Terminology Electronic information equipment electronic information equipment Equipment for collecting, processing, computing, storing, transmitting, and retrieving electronic information, including servers, switches, storage devices, etc. redundancy redundancy Duplicate configuration of some or all parts of the system , When the system fails , Redundantly configured components step in and take over the work of the failed component , This extends the system's mean time between failures. N—— basic needs N——base requirement The system meets basic needs and has no redundancies. N+X redundancy N+X redundancy In addition to meeting basic needs, the system also adds X components, X units, X modules or X path. any X Failure or maintenance of a component, unit, module or path will not cause any interruption to system operation. ( X=1 ~ N ) fault tolerance fault tolerant With two or more systems, at least one system is working normally at the same time. Infrastructure configured as a fault-tolerant system can still meet the basic needs for the normal operation of electronic information equipment after withstanding a serious sudden equipment failure or human error. Power distribution cabinet (RPP) remote power panel forCabinets arranged in rows or divided by functional areas provide equipment for power distribution management.

8. Terminology Electric energy utilization efficiency ( PUE ) power usage effectiveness A parameter that characterizes the power utilization efficiency of a data center. Its value is the ratio of the total power consumed by all electrical equipment in the data center to the total power consumed by all electronic information equipment. water use efficiency ( WUE ) water usage effectiveness A parameter that characterizes the water utilization efficiency of a data center. Its value is the ratio of the total water consumed by all water-using equipment in the data center to the total electrical energy consumed by all electronic information equipment. Automatic transfer switch electrical appliances (ATSE) automatic transfer switching equipment An electrical appliance consisting of one or several transfer switch appliances and other necessary appliances used to monitor the power circuit and automatically switch one or several load circuits from one power source to another. Dual power supply duplicate supply Power for a load is provided by two circuits which are considered independent of each other as far as safe supply is concerned. General control center ( ECC ) enterprise command center It provides a platform for centralized monitoring, command and dispatch, technical support and emergency drills for various systems in the data center. It can also be called a monitoring center. Uninterruptible power supply system (uninterruptible power supply system ups ) uninterruptible power system A system composed of a converter, switch and energy storage device can output AC or DC power when the input power supply is normal or faulty, and maintain the continuity of power supply to the load within a certain period of time. Data center infrastructure management system ( DCIM ) Data Center Infrastructure Management The data center infrastructure management system continuously collects data center assets and resource information, as well as the operating status of various equipment, analyzes, integrates and refines useful data to help data center operation and maintenance personnel manage the data center and optimize the performance of the data center.

9. Data center classification 03

10. Data center classification Interruption of the operation of electronic information systems will cause significant economic losses; The interruption of the operation of electronic information systems will cause serious disorder in public places. A class Data centers that are not Class A or B C class Interruption of the operation of electronic information systems will cause large economic losses; Interruption of the operation of electronic information systems will cause disorder in public places. B class GB50174-2017 Data Center Design Specification

11. Data center classification Performance requirements A The site facilities in the computer room of the grade-level electronic information system should be configured as a fault-tolerant system. During the operation of the electronic information system, the site facilities should not cause the operation of the electronic information system to be interrupted due to operating errors, equipment failures, external power interruptions, maintenance and repairs. B The site facilities in the computer room of the grade-level electronic information system should be configured according to redundancy requirements. During the operation of the system, the site facilities should be within the redundancy capacity, and the operation of the electronic information system should not be interrupted due to equipment failure. C The site facilities in the computer room of the grade 1 electronic information system should be configured according to basic needs. Under normal operation of the site facilities, the uninterrupted operation of the electronic information system should be ensured.
