What is a network cabinet? The function of network cabinets for the server

For a long time, when it comes to servers, we usually only care about the server's specifications, configuration, or performance, but few considerations about another component are equally important. It's a network cabinet.

So what are network cabinets, what role do they have on the server? We will learn together shortly.

What is a network cabinet?

A network cabinet, also known as a rack, a server cabinet (English: Server Rack) is a combination of hardware structures designed to accommodate technical equipment including routers (routers), switches circuits (switches), hubs, storage devices (UPSs), cables and, of course, servers. It is also possible to understand the network cabinet as a bracket that allows to keep the server and many important devices attached in a firm, fixed position, contributing to ensuring stable operation. Network cabinets are often used by businesses that own servers, are located in data centers (data centers) or communication centers and are an integral part of the server.

The devices are arranged neatly and scientifically in network cabinets

When the attached devices are arranged in a neat and scientific way, we can completely manage the server contained in the network cabinet remotely via the network with KVM Switch Over IP (KMV of Aten) without having to directly to where the server is located.

Benefits of network cabinets

For technicians operating servers in data centers, it can be said that network cabinets are an indispensable support tool. Here are some of the irreplaceable benefits that network cabinets bring:

Element helps optimize the structure, manage cabling and support cooling

1. Optimize the structure of a server system: The network cabinet is usually a frame containing a tall, spacious, breathable structure, and can accommodate a variety of different devices in the same place. according to the relatively scientific layout. This helps keep the server system's hardware devices organized in an organized manner, thereby maximizing the use of floor space. For large-scale server systems, network cabinets can also be installed side by side in long rows, when teams are called server assemblies,
2. Better cabling management: A good quality network cabinet will be designed to make cabling system management easier and more efficient. You can set up hundreds of power cables, networks, and more through these brackets while maintaining a secure, neat, and organized way.
3. Delivers efficient cooling: Keeping network devices cool to optimize overall performance is often a major challenge for any data center, and network cabinets. is a device designed to support this task. The design of the network cabinet will be optimized so that the airflow can be easily circulated from the inside out and vice versa, and can also be equipped with a cooling system, mainly a cooling fan, and other cooling devices as needed depending on actual requirements.
4. Security support (physical): Network cabinets are usually made of hard metal and have a lock to limit unauthorized acts on the internal hardware equipment system. Besides, the closed network cabinet has a door that also helps prevent accidental or intentional collision with the power button or cable, which can cause unfortunate incidents.

Choose the network cabinets accordingly

There are countless different types of network cabinets on the market today, each of which is designed according to different sizes and types of network equipment, depending on the specific requirements of the manager as well as the needs of the business. However, network cabinets can be classified based on the physical size and the number of devices it contains.

There are countless different types of network cabinets available on the market today depending on the actual requirements

As mentioned, the selection of network cabinets will mainly depend on the actual requirements of the user. Usually the network cabinets have a common width of 600mm, the parameter that you need the most attention is the height and depth of the cabinet.

The height of the network cabinets is calculated in units U (1U = 4.45cm). The sizes to choose from include 42U, 36U, 27U, 20U, 15U, 10U, and the cabinet depth is 500, 600, 800, 1000, 1100mm. In general, the area of ​​a network cabinet will depend on what devices you need to put and how much is in that network cabinet.

Ensuring safety for network cabinets

Ensuring safety for equipment in the data center in general and for network cabinets in particular is always a factor that needs to be paid attention in any case. There are several methods to help you improve the security of your network cabinets and devices in your data center as follows:

1. Note that you should buy all types of cabinets with locks both in front and behind the doors
2. Install environmental controls to proactively understand the state of the environment inside the cabinet
3. Data center managers should pay close attention to monitoring the amperage on each circuit, temperature, humidity, and other changes inside the cabinet, while recording specific data and making plans. overcome immediately when noticing abnormal signs.
4. Install a number of sensors on the cabinet door, which helps identify and can alert managers when a cabinet door is opened or not closed properly.
5. Pay special attention to fire prevention and fighting in data centers.
