What is a server?

2024-08-15

Server is a computing system or equipment that provides computing power, resources, and application services. In this digital era, servers are ubiquitous in our lives, computers, cell phones, APPs, etc. are all servers, but servers are not the same as personal computers. Compared with personal computers, servers are more powerful, with more computing power and data processing capabilities, and longer running time.

What are the main components of a server?

A server as an IT device has many components. The main components are power supply, central processing unit, hard disk drives, storage, cooling system etc.

What are the characteristics of a server?

Servers have the characteristics of scalability, ease of use, availability and ease of management.

Scalability: The enterprise network is constantly changing, the server needs to have a certain degree of scalability to adapt to the increased number of users, to avoid being eliminated in a short period of time. Scalability is reflected in the hard disk, CPU, system and other aspects of whether the upgrade or expansion.

Ease of use: the complexity of the server's functions, software system configuration, in order to facilitate the operation of the management staff, server manufacturers need to take into account the design of its ease of use, including whether the server is easy to operate, whether the user navigation system is perfect, whether the chassis design is humanized and other aspects.

Availability: The server needs to meet the requirements of long-term stable work, and can not often have problems. In large and medium-sized enterprises, servers are usually required to never be interrupted, and servers in some special application areas also need to work without interruption. In order to ensure the availability of the server, you need to take hardware redundancy, online diagnosis and other technology and configuration measures.

Ease of management: Servers need to have measures to prevent errors or failures, timely detection of problems and maintenance, reduce the chance of error and improve maintenance efficiency. The ease of management of the server is reflected in the availability of intelligent management systems, automatic alarm functions, independent management systems and other aspects.

How are servers categorized?

Servers are categorized by a variety of criteria, including system, application level, and form factor. The article focuses on servers by form factor. Servers are mainly categorized into rack servers, tower servers, cabinet servers, and blade servers.

Rack server: shape like a switch, 1U, 2U, 4U (1U = 1.75 inches) and other specifications, installed in a standard 19-inch cabinet inside, mostly for functional servers. For information service companies, due to their expensive server room, in order to deploy more servers in the limited space to reduce the cost of services, usually choose rack-mounted servers. Rack-mounted servers also have a variety of specifications, 1U rack-mounted servers are

the most space-saving, but poor performance and scalability, suitable for business relatively fixed areas of use; 4U or more products have higher performance, good scalability, easy to manage, suitable for large access to critical applications, but the volume is larger, the utilization of space is not high.

Tower server: the shape and structure and the usual use of vertical PC is almost the same, the motherboard is more scalable, the chassis is larger than the standard ATX chassis, usually reserved enough internal space for future hard disk and power supply expansion. Due to the large chassis, high configuration, scalable, very wide range of applications, the master server has the highest utilization rate. Usually commonly referred to as servers are generally tower servers, which can set a variety of common service applications in one.

Cabinet-type server: In some high-grade enterprise servers, due to the complex internal structure, more equipment, some also have many different equipment units or several servers are placed in a cabinet. Rack-mounted servers are usually made up of rack-mounted, blade-mounted servers and other equipment combinations. Rack-type servers are mostly used in securities, banks, post and telecommunications and other important enterprises.

Blade server: It is a server with multiple card-type server units inserted into a standard-height rack-mounted chassis, which is characterized by high availability and high density. A blade is a system motherboard, similar to a stand-alone server, can start its own operating system. In cluster mode, all blades can be connected to provide a high-speed network environment and share resources to serve the same users. Blade server systems can be easily replaced and minimized maintenance time.Blade server systems can be easily replaced and maintenance time minimized.

How to maintain and care for the server?

Maintenance and care for servers need to pay attention to the construction of the operating environment, hardware maintenance work, software maintenance.The operating environment is critical to the normal operation of the server, the environment to ensure adequate space, do a good job of partitioning, anti-static treatment of the floor and walls, cables, fire treatment. The temperature and humidity of the operating environment should be maintained in a certain range, the server is more sensitive to temperature and humidity, too high a temperature or humidity will cause damage to the server, or even cause fire or power leakage accidents, threatening the personal safety of the user. This requires a high-performance cooler to control the temperature of the server's operating environment.Different cooling solution or heat sink have different advantages and are suitable for different scenarios.
