Seten: Introduction to the types of servers used in daily life, and where they are mainly used

Date:December 1st,2023 View:50
The server is mainly used for databases and web services, with reliable continuous operation capabilities, powerful storage and network communication capabilities, fast fault recovery functions, and vast expansion space< Br/>


Entry level servers



Entry level servers typically use a single CPU and are equipped with corresponding memory and large capacity IDE hard drives, with IDERAID for data protection when necessary. It is mainly aimed at users based on network operating systems such as Windows NT and NetWare, and can meet the needs of office type small and medium-sized network users for file sharing, printing services, data processing, Internet access, and simple database applications. It can also complete services such as email, proxy, DNS, etc. on a small scale< Br/>


Workgroup level servers



Workgroup level servers generally support 1 to 2 P III processors or a single P4 processor, and can support large capacity ECC memory. They are comprehensive in functionality, strong in management, and easy to maintain, possessing various essential features for small servers. If the I/O system adopts the SCSI-bus, the SMP symmetric multiprocessor structure, optional RAID, hot swappable hard drives, hot swappable power supplies, etc., has high availability characteristics. Suitable for providing web, mail and other services for small and medium-sized enterprises, as well as for the construction of digital campus networks and multimedia classrooms in education departments such as schools< Br/>


Departmental level servers


Departmental level servers typically support 2 to 4 P III Xeon processors, with high reliability, availability, scalability, and manageability. Most departmental level servers have excellent system scalability, allowing users to upgrade their systems online in a timely manner when their business volume rapidly increases, which can protect their investments. At present, department level servers are a necessary link for dispersed grassroots data collection units in the enterprise network to maintain smooth connectivity with the highest level data center< Br/>


Enterprise level servers



Enterprise level servers are high-end servers that generally support 4 to 8 PIIIXeon (Xeon) or P4Xeon (Xeon) processors. They have independent dual PCI channels and memory expansion board designs, high memory bandwidth, large capacity hot swappable hard drives, and hot swappable power supplies, and have super strong data processing capabilities. This type of product has high fault tolerance, excellent scalability and system performance, extremely long system continuous running time, which can greatly protect user investment< Br/>


CISC architecture server



In CISC microprocessors, the instructions of a program are executed in sequence, and the operations within each instruction are also executed in sequence. The advantage of sequential execution is that it is easy to control, but the utilization of various parts of the computer is not high, and the execution speed is slow. The servers of the CISC architecture are mainly based on the IA-32 architecture, and most of them are used by mid to low-end servers< Br/>


If the enterprise's applications are all based on the NT platform, then the selection of servers is basically focused on IA architecture servers. If the enterprise's application is mainly based on the Linux operating system, then the selection of servers is also based on the IA architecture of servers. If the application must be based on Solaris, then the server can only choose SUN server; If the application is based on Linux, then only IBM Unix servers can be selected< Br/>


RISC architecture server



The instruction system of RISC is relatively simple, requiring only the most commonly used and limited execution of hardware, while most complex operations use mature compilation techniques, synthesized from simple instructions. At present, this instruction system CPU is widely used in mid to high end servers, especially high-end servers that all use RISC instruction system CPUs< Br/>


VLIW architecture server



The biggest advantage of VLIW is that it simplifies the structure of the processor and eliminates many complex control circuits inside the processor. These circuits are usually necessary for the coordinated parallel operation of superscalar chips. The simple structure of VLIW can also reduce the manufacturing cost of its chips, with low price, low energy consumption, and much higher performance than superscalar chips. At present, there are mainly two types of microprocessors based on this instruction architecture: Intel's IA-64 and AMD's x86-64< Br/>


Universal servers



A general-purpose server is a server that is not specifically designed for a particular service and can provide various service functions. Currently, most servers are general-purpose servers. This type of server is not designed specifically for a certain function, so it needs to consider multiple application needs during design. The structure of the server is relatively complex, and it requires high performance. Of course, it is also more expensive in price< Br/>


Dedicated servers



A dedicated server is a server designed specifically for one or several functions, which is different from a general-purpose server in some aspects. The optical disc mirror server is mainly used to store optical disc mirror files, and it needs to have corresponding functions to adapt to its performance. The optical disc mirror server needs to be equipped with large capacity, high-speed hard drives, and optical disc mirror software; FTP servers are mainly used for file transfer onlineThis requires servers to have significant advantages in hard disk stability, access speed, and I/O bandwidth; The email server mainly requires the server to be equipped with high-speed broadband internet tools and a large hard disk capacity. The performance requirements of these functional servers are relatively low because they only need to meet certain functional applications, so the structure is relatively simple, and a single CPU structure is sufficient; The requirements for stability, scalability, and other aspects are not high, and the price is much cheaper, equivalent to the price of about 2 high-performance computers< Br/>


Desktop servers



Desktop servers, also known as& Ldquo; Tower Server; ;. Low end servers, due to their weak functionality, have a relatively simple internal structure, so the chassis is not large and all adopt a desktop chassis structure. At present, this type of server holds a considerable share in the entire server market< Br/>


Rack mounted servers


The appearance of a rack mounted server does not look like a computer, but rather like a switch, with specifications such as 1U (1U=1.75 inches=4.45CM), 2U, 4U, etc. Usually, a 1U rack mounted server is the most space saving, but its performance and scalability are poor, making it suitable for some relatively fixed business usage areas; Products above 4U have high performance and good scalability, generally supporting four or more high-performance processors and a large number of standard hot swappable components. The rack mounted server is installed in a standard 19 inch cabinet. This type of structure is mostly functional servers< Br/>


For information service enterprises, when choosing servers, the first consideration is the size, power consumption, heat generation, and other parameters of the servers. This is because information service enterprises usually use large dedicated data centers to deploy and manage a large amount of server resources. The data centers are usually equipped with strict security measures, good cooling systems, and multiple backup power supply systems, and the cost of their data centers is quite expensive. How to deploy more servers within a limited space is directly related to the service cost of the enterprise. Usually, rack mounted servers with mechanical dimensions that meet the 19 inch industrial standard are selected< Br/>


Cabinet server



In some high-end enterprise servers, due to their complex internal structure and a large number of devices, some also have many different device units or several servers placed in one cabinet. This type of server is called a cabinet type server< Br/>


For securities, banks, postal and telecommunications enterprises, systems with complete fault self repair capabilities should be adopted, and redundant measures should be taken for key components. For servers used in critical business, dual machine hot backup high availability systems or high-performance computers can also be used, which can ensure good system availability< Br/>


Blade servers



There are two main types of blade servers on the current market: one is mainly designed for the telecommunications industry, with interface standards and size specifications that comply with PICMG1. x or 2. x. In the future, products that comply with PICMG3. x will also be launched, and blades and cabinets from different manufacturers using the same standard can theoretically be compatible with each other; The other type is general computing design, which may use the above standards or manufacturer's standards on the interface, but the size specifications are determined by the manufacturer, focusing on performance price ratio. Currently, most of these products belong to this category. Blade servers are currently most suitable for cluster computing and IxP to provide internet services. In cluster mode, all motherboards can be connected to provide a high-speed network environment, share resources, and serve the same user group< Br/>


IA server



Typically, servers that use Intel processors are referred to as IA architecture servers, also known as CISC architecture servers. Due to the adoption of an open architecture on this server,& Quota; Small, clever, stable& Quota; As a characteristicWith reliable performance, low price, and the implementation of industrial standardization technology and the support of a large number of domestic and foreign software and hardware suppliers, it has been widely applied globally, especially in China, with its extremely high performance to price ratio on the basis of mass production. Complete more major applications such as file services, printing services, communication services, web services, email services, database services, and application services within the internet and local area networks< Br/>
