Basic server category

In daily life and work, servers may be exposed. This is especially important for rational use of servers. Are you aware of the classification of servers? I believe that many computer enthusiasts do not know enough about this, so I will introduce the basic types of servers for your reference and hope to help you.

There are many criteria for server classification. For example, server classification by application level can be divided into working group, department-level, and enterprise-level servers. The number of processors can be divided into single, dual, and multi-channel servers; based on processor architecture
The server can be divided into X86 server, IA-64 server and the server architecture according to the server structure can be divided into type server, rack server and blade server.

However, we generally focus more on the structure of servers: tower servers, rack servers, and blade servers, which are the most widely seen, it is also the most understandable type of server structure, because its shape and structure are similar to the vertical PC we usually use. Of course, because the server's motherboard has a strong scalability and a pile of more slots, it is larger than the general motherboard, so the host chassis of the Tower server is larger than the standard ATX chassis, generally, sufficient internal space is reserved for redundant expansion of hard disks and power supplies in the future.

The so-called blade server refers to a rack-mounted chassis with multiple card-mounted server units, achieving high availability and high density. Each "Blade" is actually a system motherboard. They can start their own operating systems through an "onboard" hard disk, similar to independent servers. In this mode, each motherboard runs its own system
Different user groups specified by the service are not associated with each other.

For enterprises, when selecting servers, they must first consider physical parameters such as server volume, power consumption, and calorific value. How to deploy more servers in the limited space of data centers is directly related to the service costs of enterprises, rack servers are usually used. Rack servers also have a variety of specifications, such as 1u (45cm high), 2u, 4u, 6u, 8u, etc. Generally, 1u rack-mounted servers save the most space, but have poor performance and scalability. Therefore, 1u servers are suitable for some relatively fixed application fields. More than 4 U products have high performance and good scalability.
　

The above is a detailed introduction to the basic classification of servers. After reading the introduction, I believe everyone has a certain degree of understanding and hope that the content will be useful to everyone,
