We should all know the word "data is priceless". Since data is so important, it is necessary to choose a secure and stable data server, so how to choose a reliable and stable data server? We start from five aspects to help you understand what requests the database server has to the server hardware.

1. High function criteria of database

Ensure that the selected server can not only satisfy the operation of the operation system and the needs of business processing, but also satisfy the increase of business volume in a certain period of time. Usually, the required server TPMC value can be calculated according to the experience formula (Tpmc is a program that measures the business processing capability of the computer system), and then compare the TPMC value of each server manufacturer and TPC, and select the corresponding model. Together, use the market price / quotation of the server to remove the calculated TpmC value to get the quotation per unit TPMC, and then select the server with high functional quotation ratio.

Conclusion: the function of the server processor is very important, the main frequency of CPU should be high, and it should have a large cache.

two。 Database security and reliability criteria

The principle of reliability is the primary consideration in all selection of equipment and systems, especially in large systems with a lot of requests and long-running requirements. To think about the reliability of the server system, we should consider not only the reliability or stability of a single node of the server, but also the overall reliability of the connection between the server and the relevant auxiliary system, such as network system, security system, remote printing system and so on. When necessary, you should also consider choosing clustering skills for important servers, such as dual hot backup or cluster parallel access skills, and perhaps even complete fault-tolerant machines.

Conclusion: the server should have redundant skills, and devices such as hard disk, network card, memory and power supply should be used stably, followed by function.

3. Scalability criteria of database

Ensure that the selected server has excellent scalability criteria. Since the server is the center of all system processing, the request has a big data throughput rate, including: Icano rate and network communication rate, and the server needs to be able to handle the amount of data brought about by business development in a certain period of time. The demand server can upgrade itself according to the needs of the business at the corresponding time. Such as: CPU type promotion, memory expansion, hard disk expansion, replacement of network cards, adding the number of terminals, hanging disk arrays or with other servers to form a cluster system for concurrent access to converged data. All of this requires that the selected servers have an outstanding scalability on the whole. Usually, database and billing application servers will choose cluster mode to add reliability in the planning of large-scale billing system. According to the amount of data and investment consideration, the attached disk storage system can choose DAS, NAS or SAN to complete the skills.

Conclusion: the IO of the server should be high, otherwise there will be a bottleneck when both CPU and memory are highly functional. In addition, the scalability of the server is better in order to meet the needs of the company in the future.

4. Security guidelines for servers

Most of the servers deal with the central data about the system, on which important transactions and major data are stored and run. These transactions and data are a major asset for owners, and their security is very sensitive. The security of the server is closely related to the security of the system, such as the security of the network system, data encryption, code system and so on. Server requirements in itself, including software and hardware, should be considered from the perspective of security, with the help of external security facilities to ensure their own high security.

Conclusion: first of all, from the data of the server, it should have the conditions of high hardness and high protection, and secondly, the cooling system of the server and the ability to adapt to the environment should be strong, so that the security request of the server can be satisfied in hardware.

5. Server is conducive to the rational criterion of manageability.

The server is not only the center but also a node in the whole system, just as the network system needs to manage and protect, it also needs to deal with the server usefully. This requires the software and hardware of the server to support the standard management system, especially the operating system, which also contains some major system components.

Conclusion: try to choose servers with more supporting systems, because the more compatible servers are, the more choices you can have.

Finally, a summary.

First of all, the functional request of the database server is very high, so there are high requests in CPU, memory, and hard disk, followed by storage, storage should have outstanding stability, to satisfy the long-running server to read and write at any time and other operations will not show errors. Finally, I hope that the above five points will help you choose the database server you need.
