This article mainly introduces how Linux operation and maintenance engineers should choose the database server, the article is very detailed, has a certain reference value, interested friends must read it!

First, the first thing is to ensure that the selected server can not only meet the needs of the operation of the operating system and business processing, but also meet the growth of business volume in a certain period of time. Generally, you can calculate the required server Tpmc according to the empirical formula, and then compare the Tpmc prices announced by various server manufacturers and Tpmc organizations, and choose the server with high performance-price ratio today.

Second, to ensure that the selected server has excellent scalability principles. Because the server is the core of all system processing, it is required to have 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 server needs to be able to upgrade itself according to the needs of business development at the corresponding time. Such as: CPU model upgrade, memory expansion, hard disk expansion, replacement of network card, increase the number of terminals, hanging disk array or with other servers to form a cluster system for concurrent access to centralized data. All this requires that the selected server has a good room for expansion as a whole. General database and billing application servers will use cluster mode to increase reliability in the design of large-scale billing system. According to the amount of data and investment considerations, the attached disk storage system can use DAS, NAS or SAN technology.

Third, the principle of reliability is the primary consideration in all selection of equipment and systems, especially in large-scale systems with a large number of processing requirements and long-term operation. Considering 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 systems, such as network system, security system, remote printing system and so on. When necessary, you should also consider using clustering technology for key servers, such as dual hot backup or cluster parallel access technology, or even possible full fault-tolerant machines.

Fourth, the server is not only the core but also a node part of the whole system, just as the network system needs management and maintenance, but also needs to manage the server effectively. This requires the software and hardware of the server to support the standard management system, especially the operating system, including some important system components.

Fifth, the server mostly deals with the core data of related systems, on which key transactions and important data are stored and run. These transactions and data are an important asset for owners, and their security is very sensitive. The security of the server is closely related to the overall security of the system, such as network system security, data encryption, cryptosystem and so on. The server itself, including hardware and software, should be designed and considered from the perspective of security, with the help of external security facilities, but also to ensure its own high security.
