Editor to share with you how to configure the server of small and medium-sized enterprises, I believe that most people do not know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. Let's learn about it!

Common server applications in small and medium-sized enterprises

Small and medium-sized enterprises are relatively weak in terms of scale and strength, which are mainly reflected in the financial strength. In the early stage of the development of the enterprise, the scale of the company is relatively small, the volume of business is not large, the demand for information construction is not strong, and the effect is not obvious, so the information construction in the initial stage will not invest too much money, and the procurement server is generally based on the principle of less money. the principle of doing more work, pursue the rate of return on funds.

In addition, the lack of strength is also reflected in the lack of corresponding IT talents. Specialized IT staff will add an additional expense. Generally speaking, small businesses with little or no dedicated IT staff generally have little or no dedicated IT personnel for cost reasons. It is worth mentioning that the traditional focus on input costs, now pay more and more attention to operating costs. When choosing the deployment configuration of the server, enterprises can not blindly pursue low cost while ignoring the availability, manageability and scalability of the server. The initial procurement cost only accounts for part of the enterprise's total cost of ownership, while the later hardware upgrade costs, management and maintenance costs, personnel costs and so on may be close to or exceed the initial procurement cost. Therefore, low price, easy to manage, stable and reliable server products are more suitable for small and medium-sized enterprises, and can reduce the total cost of ownership for enterprises.

Mail and Web server configuration considerations

At present, the most basic server applications are file server, database server, mail server, Web server, multimedia server, terminal server and so on. These applications have different requirements for server configuration. Purchasing servers with different configurations according to different applications can make full use of server resources and avoid the waste of funds and server resources. In the following, the configuration requirements of these servers will be analyzed one by one to provide reference for enterprises.

Mail server

In this day and age, there are few enterprises that do not use mail to work. Generally speaking, mail servers do not have high requirements for processor performance, but there are certain requirements for network subsystems and memory in order to support a certain number of concurrent connections. The mail server software also has high memory requirements. At the same time, the mail server needs a large storage space to store mail and some files, but for small and medium-sized enterprises, the number of enterprise mailboxes is generally less than a few hundred, so the requirement for the configuration of the server is not high. an entry-level server can carry the needs of hundreds of mail clients. The hardware requirements of mail server are memory, disk, network system and processor in turn.

Web server

Different website content for Web server hardware requirements are also different, if the Web site is static, the hardware requirements for Web server from high to low are: network system, memory, disk system, CPU. If the Web server mainly does intensive computing (such as dynamically generating Web pages), the hardware requirements for the server are as follows: memory, CPU, disk subsystem, and network system.

Terminal server

Because the terminal server adds all the load of the client to the server, it has certain requirements for the processing capacity of the server. The processor should be able to carry a certain number of concurrent requests and provide fast response speed. If the processing capacity is not enough, it is easy to cause slow response of the server, software errors and even downtime. High-speed and large-capacity memory can improve the response speed of the terminal server, and it is also one of the necessary conditions to improve the overall performance. Because the amount of data transmission between the terminal server and the client is not very large, the requirement for the network is not very high, and the terminal server is mainly used in the internal network of the enterprise. the internal high-speed LAN environment can fully meet the bandwidth requirements between the terminal server and the client.

Customers who use Terminal Services can remotely access the server with a graphical interface, and can call applications, components, services, and so on. The priority of terminal server for hardware requirements is processor, memory, disk and network system.

File and database server configuration considerations

File server

The file server is an intranet server that uses the network to provide access requests and service delivery for users, and the file server is used to manage shared files. In the enterprise, some files need to be shared, such as PPT, software, etc. Users need to download or upload files through sharing or FTP. The file server carries the transfer of mass data between the server and the user's disk. Therefore, the file server is highly dependent on the network, and the quality of network bandwidth directly affects the file sharing and access experience of users.

In addition, file sharing naturally involves the read and write operation of the disk, so there are certain requirements for the capacity and speed of the disk subsystem. Selecting disks with high speed, high interface speed and large cache capacity, and setting up disk arrays, such as RAID 0 and RAID 5, can effectively improve the speed of file transfer in the disk system. In addition, large memory can reduce the number of reading and writing to the hard disk, provide buffering for file transfer, and improve the speed of data transfer. In summary, the priority of the file server for hardware requirements is network system, disk system and memory.

Database server topology

Database server

The database server has high requirements for all aspects of the system, and it has certain requirements for memory, disk and CPU computing power to deal with a large number of random I / O requests and data transfer. In terms of memory, the database server needs high-capacity and high-speed memory to save the time for the processor to access the hard disk and improve the response speed of the server. Today's Xeon processors generally support multiple memory channels, and each channel can support multiple memory slots. For cloud computing work virtualization applications and private cloud deployment, memory support is already very strong. For this reason, in the area of memory, the current memory technology and product development is still very mature.

The database server also has high requirements for processor performance. The database server needs to query according to the requirements, and then feed back the results to the user. If there are a lot of query requests, such as when a large number of users query at the same time, if the processing capacity of the server is not strong enough to handle a large number of query requests and respond, then the server may respond slowly or even crash.

In the aspect of disk, the high-speed disk subsystem can also improve the query response speed of the database server, which requires the disk to have high-speed interface and rotational speed. At present, many large machines are gradually transitioning to the mixed application of HDD and SSD, which helps to greatly improve the disk I / O, reduce the cost and energy consumption, and improve the ease of use.

The database server also has high requirements for processor performance. The database server needs to query according to the requirements, and then feed back the results to the user. If there are a lot of query requests, such as when a large number of users query at the same time, if the processing capacity of the server is not strong enough to handle a large number of query requests and respond, then the server may respond slowly or even crash. At present, the development of processor technology is very advanced, which can not only query quickly and accurately, but also realize millisecond big data query, statistics and analysis. For small and medium-sized enterprise users, the use of mainstream two-way, four-way extremely strong chip, can fully meet the demand.
