How to Choose the Right Cabinet? Network Cabinet & Server Rack
Leave a message
Many people can't distinguish the difference between a network cabinet and a server rack,
which makes it difficult to choose the right cabinet, and even choose an unsuitable cabinet, causing many problems for later applications. This article will explain how to choose the right cabinet.
1. Server Rack
Usage:
The server rack is used to install standard equipment and non-standard equipment such as servers, network storage devices, monitors, and UPS. The depth, height, and load capacity of the server rack is all required.
The structure of the server rack should have good strength, as well as good electromagnetic isolation, grounding, sound insulation, ventilation, and heat dissipation. In addition, the server rack should have performance characteristics such as vibration resistance, shock resistance, corrosion resistance, dust resistance, water resistance, and radiation resistance. These performance characteristics ensure the stable operation of the server rack to the greatest extent possible and avoid the problem of the server rack malfunctioning due to external influences.
Server rack depth
The depth is generally 1000mm (1 meter) and is most commonly found in the market. There are also 800mm, 900mm, 1200mm, etc.
Taking the general storage equipment on the market as an example, the depth is generally around 670mm. However, considering that the equipment back panel needs to be wired, and for 10-gigabit storage, fiber optic cables cannot be bent, it is generally better to choose a depth of 1 meter or more for the cabinet. Network storage devices are generally of similar sizes.
Server rack width
The width is generally 600mm.
Server rack height
The height has many sizes, such as 12U, 20U, 42U, and so on.
The "U" in the cabinet refers to the unit of server size. 1U is 4.445CM high and 600CM wide (cabinet width). For 1U, the depth is generally not specified. Server racks are generally set to 1000CM deep (cabinet depth).
Server rack load capacity
The load capacity is generally 800 kg or more (1600 pounds).
Front and Rear Door Through-holes
Because the server equipment generates a large amount of heat, both the front and rear doors have ventilation holes, or there is no door. A cabinet without doors is generally called a rack.

2. Network Cabinet
Usage:
The network cabinet focuses more on the needs of the wiring market. The network cabinet is mainly used to store network devices and accessories such as routers, switches, and patch panels.
Cabinet Depth
The depth is generally 600mm, but some are also 800mm. (The depth of the network cabinet is obviously not enough to hold server equipment.)
Cabinet Width
The width is generally 600mm.
Cabinet Height
The height has many sizes, such as 12U, 20U, 42U, and so on.
The "U" in the cabinet refers to the unit of server size. 1U is 4.445CM high and 600CM wide (cabinet width). For 1U, the depth is generally not specified, and the network cabinet is generally set to 800CM deep (cabinet depth).
Cabinet Load Capacity
There is generally no need for a high load capacity in a network cabinet, which is usually not as good as a server rack.
Front and Rear Door Through-holes
The front door is generally a transparent tempered glass door, with low requirements for heat dissipation and the environment.
3. Common Installation Methods for Cabinets
Tray
The cabinet tray is generally fixed on the cabinet to support and store equipment such as servers, switches, and other devices. Therefore, the load-bearing capacity of the cabinet tray must be strong enough to provide good support for the equipment. The tray size should be determined based on the width and depth of the cabinet.
Guide Rail
The installation of guide rails on the cabinets and storage devices ensures that the server can be pulled in and out of the cabinet flexibly and conveniently, and is safe and stable
.
Angle Iron
Angle iron is also used to support equipment and is installed on the uprights inside the cabinet. Its principle is similar to that of the tray, but it does not have a board in the middle. The size is determined according to the depth of the cabinet.
In summary, when purchasing network storage equipment and server equipment, it is best to choose a server rack with a depth greater than 1 meter, good ventilation, and strong load-bearing capacity. Network cabinets are suitable for products that do not require high depth, such as switches and hubs.
Although both network cabinets and server racks are rectangular boxes in appearance and have similar functions, their main functions are very different in actual use. Blindly purchasing a cabinet without understanding the specific requirements may result in a mismatch between the cabinet type and the corresponding storage device, rendering them unusable. Therefore, before making a purchase, it is necessary to communicate the specific requirements (such as size) with the manufacturer in order to customize the most suitable cabinet.
