数据中心标准机柜设计方案(数据中心机柜如何选型)

The appearance of a 19-inch standard cabinet has three conventional indicators: width, height, and depth. Although the installation width of 19-inch panel equipment is 465.1mum, the common physical widths of cabinets are 600mm and 800mm. The height generally ranges from 0.7M-2.4M, depending on the number of equipment in the cabinet and the unified style. Usually manufacturers can customize special heights. Common finished 19-inch cabinet heights are 1.6M and 2M.

The depth of the cabinet generally ranges from 400mm-800mm, depending on the size of the equipment in the cabinet. Usually manufacturers can also customize products with special depths. The common depths of finished 19-inch cabinets are 500mm, 600mm, and 800m19-inch standard The height occupied by equipment installation in the cabinet is represented by a special unit U, 1U=44.45m. Equipment panels using 19-inch standard cabinets are generally manufactured according to nU specifications.

For some non-standard equipment, most of them can be installed into the 19-inch chassis and fixed through additional adapter baffles.

Extended information:

The compatibility of network cabinets is a very troublesome issue for users. Data computer room equipment comes from different manufacturers, and the same manufacturer has different Models, these devices do not form a unified specification, which requires the network cabinet to have the compatibility of each device. As data center construction develops towards overall availability, the demand for network cabinet management in computer rooms is growing day by day.

The cabinet is an important part of the data center computer room. The function of the cabinet is to facilitate the installation of fixed servers and IT equipment, and to provide these equipment with a convenient and beautiful wiring system. It can also provide Security protection and so on.

How many servers can be placed in a data center cabinet depends on many convenience factors. For example, a data center uses a 42U high standard cabinet, but uses a 2U high 550W server. The following two solutions can be adopted:
One: If the servers are placed according to the installation space, the maximum number of servers that can be placed in a cabinet is 42U/2U=21 (units).

Two: Considering the maintenance issues of the operating environment, such as the temperature not being too high, in order to maintain the operating environment of the server and facilitate the cooling of the server, it is recommended that the total power of a cabinet should not exceed 10KW.

Based on this total power limit, the number of servers installed in a cabinet is calculated as

10*1000W/550W=18 (units).

A cabinet with a total power of 10KW is a high heat density layout and has high cooling requirements. Therefore, if space allows, it is generally not recommended to place a cabinet with such a high heat density. Generally, a cabinet placement plan with a total power of 3KW-6KW is recommended. (3KW is more). If it is 3KW, then the number of servers installed in a cabinet is 3*1000W/550W=5 (units).

With the rapid development of the Internet, the construction of data center (IDC) computer rooms has become more and more important. The IDC computer room is an important storage and transmission center for Internet information and one of the core infrastructures for enterprise information construction. Therefore, the planning and design of the IDC computer room is very critical.

This article will introduce the planning and design steps of IDC computer room construction, as well as related precautions.

1. Demand analysis

Before planning and designing the IDC computer room, a demand analysis needs to be performed first. This step is very important because only by understanding the customer's needs and requirements can appropriate planning and design solutions be developed.

In the process of demand analysis, the following aspects need to be considered:

1. Business needs: It is necessary to understand the customer’s business type, business scale, business characteristics and other information in order to provide The customer provides a suitable computer room design plan.

2. Equipment requirements: It is necessary to understand the customer's equipment type, quantity, power and other information in order to provide customers with a suitable computer room equipment configuration plan.

3. Security requirements: It is necessary to understand the security requirements of customers, including physical security, network security, data security, etc., in order to provide customers with safe and reliable computer room design solutions.

2. Computer room planning

When planning the computer room, the following aspects need to be considered:

1. Computer room location: The location of the computer room needs to be selected in a safe location , stability, ventilation, drainage, power supply and other aspects are relatively complete.

2. Computer room area: Determine the computer room area according to customer needs and requirements, including the number of racks, number of cabinets, operating areas, passages, etc.

3. Computer room layout: Design the layout of the computer room according to the computer room area and customer needs, including racks, cabinets, operating areas, passages, etc.

4. Computer room equipment configuration: According to the customer’s equipment needs and requirements, determine the equipment configuration of the computer room, including UPS, air conditioning, fire protection, monitoring, etc.

5. Computer room security: According to the customer's security needs, design the physical security, network security, data security and other aspects of the computer room to ensure the safety and reliability of the computer room.

3. Computer room design

When designing the computer room, the following aspects need to be considered:

1. Computer room construction: According to the requirements of the computer room planning, The design of the computer room building includes the walls, floors, ceilings, etc. of the computer room.

2. Computer room power: According to the power requirements of the computer room equipment, design the computer room power, including power distribution system, UPS, generator, etc.

3. Computer room air conditioner: Design the computer room air conditioner according to the heat load of the computer room to ensure that the temperature, humidity, air circulation, etc. of the computer room meet the requirements.

4. Computer room fire protection: According to the safety requirements of the computer room, design the computer room fire protection, including fire alarm system, fire extinguishing system, etc.

5. Computer room monitoring: According to the security requirements of the computer room, design the computer room monitoring, including video surveillance, access control systems, etc.

Standard server cabinet dimensions include cabinet height, cabinet width, cabinet depth, etc.

1. The height of the cabinet

is determined by the number of servers and other equipment placed in each cabinet and the number of Us occupied. In data centers, cold (hot) aisles usually need to be sealed. In order to ensure that the height of personnel passage should not be too low, 42U/47U cabinets are usually used.

2. Cabinet width

The width of the plug-in panel is 482.6mm, and the width of server cabinets is commonly 600mm. Network cabinets with many cables often use 800mm wide cabinets. The 600mm wide cabinet provides 25~30mm of cable management space on both sides, and the 800mm wide cabinet provides 123mm of cable management space on both sides.

3. Cabinet depth

In order to meet the versatility, the data center can install various server equipment and reserve sufficient cabling space. The depth Usually not less than 1100mm. Most use a depth of 1200mm based on the width of two anti-static floors.

Introduction to the functions of the cabinet:

1. Installation and fixation: IT equipment, servers and other equipment can be installed and fixed. The main fixation method is 19-inch rack type Install and fix on the U column. Since the main frame and U-column design of the cabinet makes it easier to install equipment and has a relatively strong load-bearing capacity, more equipment can be installed in the cabinet, and it is relatively neat and beautiful.

2. Cable management: There are various cable management slots, cable management racks, cable management boards and cable channels inside the cabinet, which provide very convenient wiring management for various equipment installed inside the cabinet.

3. Protection: The cabinet is a relatively closed space. After the front and rear doors are closed, it can protect the internal equipment from accidental damage. For example, mice can be placed inside the cabinet to damage equipment or cables.
