Today, I will talk to you about the main types of servers, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

Servers are mainly divided into four categories: entry-level servers, working group-level servers, department-level servers and enterprise-level servers; servers provide computing or application services for other clients in the network; servers have high-speed CPU computing capabilities, long-time reliable operation, strong "Icano" external data throughput and better scalability.

According to the application level, the server type is divided into four categories: entry-level server, working group-level server, department-level server and enterprise-level server; according to the purpose, it is divided into general-purpose server and special-purpose server. It can also be divided by chassis structure, processor architecture, etc.

Divided by application hierarchy:

1. Entry-level server

Entry-level servers usually use only one CPU, configure corresponding memory (such as 256MB) and high-capacity IDE hard drives as needed, and, if necessary, use IDE RAID (a disk array technology to ensure the reliability and recoverability of data) for data protection. The entry-level server is mainly aimed at users based on Windows NT,NetWare and other network operating systems, and can meet the needs of small and medium-sized office network users for file sharing, printing services, data processing, Internet access and simple database applications, and can also complete services such as E-mail, Proxy, DNS and so on in a small range.

For the office needs of a small department, the main function of the server is to complete the file and print service, which is one of the most basic applications of the server. The requirement for hardware is low. Generally, the entry-level server with single or double CPU can be used. In order to provide enough print buffer for the printer, large memory is needed, in order to cope with the frequent and large number of file access requirements, there is a fast hard subsystem, and good management performance can improve the efficiency of the server.

2. Workgroup-level server

Working group-level servers generally support 1 to 2 P Ⅲ processors or a single P4 (Pentium 4) processor, which can support large capacity of ECC (a memory technology, often used on the server) memory, with comprehensive functions. It is manageable and easy to maintain, and it has all kinds of necessary features of small servers, such as the I mango O (input / output) system using SCSI (a kind of bus interface technology) bus, SMP symmetrical multiprocessor structure, optional RAID, hot-swappable hard disk, hot-swappable power supply and so on. It is suitable for providing Web, Mail and other services for small and medium-sized enterprises, and can also be used for the construction of digital campus network and multimedia classrooms of schools and other education departments.

In general, if the application is not complex, such as no large database to manage, then the use of workgroup-level servers can meet the requirements. The quality of domestic servers is almost the same as that of foreign famous brands, especially in the middle and low-end products, the performance-to-price ratio of domestic brands has greater advantages, small and medium-sized enterprises can consider to choose some domestic brand products. In addition, large manufacturers such as HP have even launched servers specially tailored for small and medium-sized enterprises. However, if individual enterprises have more complex business, more data flow, and funds permit, they can also consider choosing departmental and enterprise-level servers as their mission-critical servers. HP, DELL, IBM and Chao are all good brands.

3. Departmental server

Departmental servers can typically support 2 to 4 P Ⅲ Xeon processors with high reliability, availability, scalability, and manageability. First of all, a large number of monitoring and management circuits are integrated, with comprehensive server management capabilities, such as temperature, voltage, fan, chassis and other state parameters. In addition, combined with the server management software, managers can know the working status of the server in time. At the same time, most department-level servers have excellent system scalability, and users can upgrade the system online in time when the volume of business increases rapidly, which can protect users' investment. The departmental server is a necessary link for the scattered grass-roots data collection units in the enterprise network to maintain smooth communication with the highest-level data center. Suitable for medium-sized enterprises (such as finance, post and telecommunications and other industries) as data centers, Web sites and other applications.

4. Enterprise server

Enterprise server is a high-end server, generally can support 4 to 8 PIII Xeon (extremely strong) or P4 Xeon (extremely strong) processors, with independent dual PCI channels and memory expansion board design, with high memory bandwidth, large capacity hot-swappable hard disk and hot-swappable power supply, with super data processing capacity. This kind of products have high fault tolerance, excellent expansion performance and system performance, and very long system continuous running time, which can protect the investment of users to a great extent. It can be used as a database server for large enterprise networks.

Enterprise servers are mainly suitable for large enterprises and important industries that need to deal with a large amount of data, high processing speed and high reliability (such as finance, securities, transportation, post and telecommunications, communications, etc.), and can be used to provide ERP (enterprise resource allocation), e-commerce, OA (office automation) and other services.

Server is a kind of computer, which runs faster, has a higher load and is more expensive than ordinary computers. The server provides computing or application services for other clients (such as PCs, smartphones, ATM terminals and even large devices such as train systems) in the network. The server has high-speed CPU computing ability, long-time reliable operation, strong external data throughput and better expansibility. According to the services provided by the server, generally speaking, the server has the ability to respond to service requests, undertake services, and guarantee services. As an electronic device, the internal structure of the server is very complex, but it is not much different from the ordinary computer internal structure, such as: cpu, hard disk, memory, system, system bus and so on.

After reading the above, do you have any further understanding of the main types of servers? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
