Where is server rack use?

It is impossible to imagine a data center or server room without such furniture. Server racks or cabinets are used in all industrial premises designed for server work. According to the construction, the following types of server furniture are distinguished:

• Open-frame server racks are structures without sidewalls. They have two or four posts with holes for mounting devices.

• Enclosed cabinets with sidewalls. They remind of a box and provide a higher level of protection.

From the point of view of its mounting, they distinguish the following models:

1. Floor-standing server racks.
2. Wall-mounted network racks.
3. Portable server racks with handles or casters.

How Do Server Racks Work?

The basis of any data center is engineering systems that are complex professional equipment. How server racks work depends on the correct implementation of engineering systems. In total, there are 5 main engineering systems of a server room:

1. Rack power supply. The main source of data center life. The stability of the equipment located in it depends on how correctly and uninterruptedly power is supplied to the server room. Thus, the data center is connected to the power grid through several independent “inputs”; uninterruptible power systems are installed, and an additional diesel generator is connected in case of a complete shutdown.

2. Conditioning. Since hardware overheating is unacceptable, while any computer system consumes a lot of energy and generates a large amount of heat, Ventilation must be organized properly. To cool the data center, professional precision air conditioners are used, as well as various modern rack cooling systems.

3. Security. It is important not only to place the equipment in server rooms, but also to ensure its complete safety and confidentiality of the stored data. Data center security systems include an access control system, video surveillance, fire alarms, emergency fire extinguishing systems, and others. It is important to prevent problems proactively. For example, the use of special sensors for early fire detection can avoid large-scale disasters.

4. Data transfer. A stable and uninterrupted data transfer process is essential for any server room. To provide it, both dedicated channels and public Internet networks with wide bandwidth are used. Channels must be backed up.

5. Dispatching. Ensuring the stable operation of the entire data center is impossible without a monitoring and dispatching system. All systems are monitored around the clock, and the problems detected are eliminated according to pre-developed algorithms. This eliminates errors and allows you to solve problems as quickly as possible.

All these points are taken together to ensure organizing the continuous and uninterruptable operation of the data center, minimizing the risks of unforeseen situations that would not only interrupt the system operation for an indefinite period but also bring large financial losses.

Noise Reduction

When answering the question “how do server cabinets reduce noise”, note that some enclosed models are produced using a special material that allows reducing the level of noise.

Heat Reduction

To ensure the required temperature level inside the server cabinet, both natural or forced ventilation is applied. The first type is inherent to open-frame racks, while the second one is applicable to closed models.

Furniture Dimensions

The size of the server cabinet varies and ranges from small cabinets for offices up to large racks for separate premises. Note that most racks have a standard width that is 19 inches. The height of server racks is usually measured in rack units (where 1 unit is 1.75 inches). Thus, there can be 6U, 9U, 15U, and others.

What Are the Components in a Rack Server?

Each rack server is equipped with a set of essential components, although their specific capacities may vary depending on individual data and computing requirements. Here are the common components found in most rack servers:

1. Motherboard: The central server board that facilitates communication and connectivity between various system components and data buses.
2. Central Processing Unit (CPU): The processor responsible for executing instructions and managing processes within the server rack. It acts as the brain of the computer, enabling data processing.
3. RAM (Random Access Memory): The active data processing capacity of the server stack. More server units can be added or removed to scale up or down the RAM capacity, allowing for flexible upgrades without extensive reconfigurations.
4. Host-Bus Adapter (HBA): A component that enables the connection of external devices, such as networked storage, to the server.
5. I/O Ports: These ports, including USC, serial ports, or AUX ports, provide connectivity options for peripheral devices. Their placement in the server rack design can significantly impact functionality and flexibility based on the server’s size, configuration, and use case.
6. Drive Bays: Auxiliary drive bays are typically included in server rack configurations, allowing for the addition of more hard disk drives (HDDs) or solid-state drives (SSDs) as per the changing storage needs.
7. Extra Equipment: Additional accessories enhance the manageability of the server stack. Common examples include rack rails for easy installation, cable management bars for organizing cables, and an efficient cooling system to maintain optimal temperature and performance.

By understanding and optimizing these components, a rack server can be tailored to meet specific computing demands while ensuring efficient operation and future scalability.
