II. General Requirements

2.1 System Overview

One set of integrated modular computer room will be built, which consists of 15 42U high 19 'cabinets, 1 integrated UPS cabinet, 2 Shante 40KW precision air conditioners and cold and hot channel components. The built-in rack Lingxiao UPS is integrated with refrigeration system, power distribution system, wiring system, lighting system and power environment monitoring system.

The system of this scheme has built-in rack-mounted UPS, rack-mounted output power distribution unit and rack-mounted air conditioner, which occupies a small installation space and the system occupies an extremely compact space. The installation method of placing the precision air conditioner and the server cabinet side by side and the hot and cold channel technology are adopted, which greatly reduces the air supply and return air path and resistance of the air conditioner, and avoids the mixing of hot and cold air flow, so the air conditioner can achieve the highest cooling efficiency.

General requirements:

The cold and hot channels are fully enclosed, with low dependence on the environment, noise and dust isolation, and more efficient use of cold energy, lower PUE, average PUE1.35

Industry innovative intelligent pop-up design, efficient response to the risk of refrigeration failure

Opening the door can be manually rotated to open the door, or the screen can be clicked to open the door, which does not affect each other and is more intelligent.

The air conditioner supports low-load dehumidification function, greatly reducing the risk of condensation in the cabinet at the beginning of the business.

Full modular design, rack installation, expansion easier

Supports stand-alone, N 1 redundant, 2N redundant multiple configurations

LCD touch capacitive screen, display comprehensive rich, smooth and fast operation, strong sense of experience

Standard cascade cabinet, split air conditioning design, for relatively high load occasions

Pre-set wiring system, saving on-site installation time and convenient follow-up maintenance

Strong and weak current wiring is clear, with strong current wiring rack on one side of the cabinet and weak current wiring slot on the other side.

Thiel certification, seismic certification, CCC certification, environmental certification and other certification.

2.2 system function

1, to ensure that the layout of the computer room is reasonable, comfortable and pleasant (to meet the "man-machine coexistence");

2. Ensure the operating environment of IT equipment, and the temperature, humidity and cleanliness meet the standard requirements of the computer room;

3, to ensure high reliability, high stability of the electrical system, fully guarantee the safe operation of IT equipment;

4, to ensure the computer room management staff efficient, centralized and intelligent working environment;

5. Ensure that the indicators of power and environment-related parameters of the computer room meet the requirements of "GB 50174-2017" Code for Design of Data Centers.

6, reduce costs, improve server resource utilization. The use of cloud platform technology to achieve server consolidation, can control and reduce the number of physical servers, can significantly improve the utilization of physical servers and their CPU, thereby reducing hardware costs.

7, improve the reliability of business systems. Through the cloud platform dynamic hot migration, load balancing strategy, host high availability (HA) and other advanced functions, combined with the redundancy mechanism of the business system itself, data and information migration can be carried out without interrupting the operation of the system. This can greatly improve the reliability of system operation.

8. Realize the rapid deployment of business systems and dynamically expand resources. Through the cloud platform, managers proactively plan for resource growth in advance, accelerate the deployment of new servers and applications, and shorten server reconstruction and application loading time.

9. Improve operational efficiency and service levels. Managers can use the unified and centralized resource monitoring and management, data analysis and visualization functions of the cloud platform to make more scientific auxiliary operational decisions, and ultimately achieve the purpose of improving operational efficiency and service levels.
