Floor Standing Server Rack
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.
Benefits of network cabinets
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.
The height of the network cabinet
In general, determining the height of the network cabinets is very important. You should not only consider the current use needs but also the future developments of. Be sure to choose the type of closet so that you can comfortably arrange hardware devices and cable routing in the most scientific way. This is not just a matter of whether you can fit the necessary equipment into the network cabinets, but also to promote ventilation, clean and neat inside the cabinet space. A spacious network cabinet, devices that are arranged in harmony will certainly give better cooling effect, more safety, and help improve the performance of the server.
The height of the network cabinets is calculated in separate units, called U or ru (rack unit, rack unit). In particular, 1U = 1.75 inch (4.45cm), common sizes for you to choose include 42U, 36U, 27U, 20U, 15U, 10U . More specifically, a 9U network cabinet (standard size) will 19 inches (approximately 48cm) wide and 15.75 inches (approximately 40cm) high.
Depth of network cabinets
Determining the depth of the network cabinets is also not a simple task because there will be many factors that you must consider. Information about the depth of the network cabinet will include several parameters:
Overall depth: Include the distance between the front and back of the cabinet as well as the thickness of the doors.
Maximum depth of use: It is the distance between the front and the back (front and back doors) of the cabinet, the thickness of the door, as well as every other part of the cabinet such as the bearing beams or parts, connecting Other additional profiles.
Maximum distance between racks: Normally in a network cabinet there will be at least 4 component racks, evenly divided between the front and the back of the cabinet. In fact, the width between the standard 19-inch brackets, however, the distance from the front stand to the back side is adjustable. Thus the maximum distance between the supports is the position after they are adjusted to the maximum distance from each other.
Maximum depth that can be set up: Small type network cabinets. Usually the maximum depth that the appliance can be placed will be equivalent to the internal depth of the cabinet when the brackets are placed furthest away from each other.
In summary, 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.
Obviously, the need for the size of a small retailer's network cabinets will be different from the needs of a large telecommunications company or a medium-sized office.
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.
