What factors should be considered when choosing information technology equipment?

1, advanced: the application of security equipment should represent the highest level of contemporary computer technology, and higher performance can be obtained with more advanced technology. At the same time, the system must be developed from a mature system and recognized as the leading product in the same market, and the system has a good future development prospect and can adapt to the needs of technological development and business development at any time.

2. Practicality: Safety equipment should have the advantage of cost performance, and the configuration goal should be to meet the design requirements of the application system, rather than blindly pursuing the highest performance and maximum capacity. In short, it is necessary to configure the appropriate processing performance and capacity according to the requirements of the application, and also consider the increase of information in the future.

3. Scalability: The security system can be expanded with the increase of the system, with a long life cycle and scalability, and can adapt to the current and future needs. By adding internal or external hardware. Such as expanding the number of CPU (SMP), increasing memory, increasing the number and capacity of hard disks, and increasing adapters (cards) on I/O bus. , or replace existing components with new hardware components with poor performance. For example, the upgrade of CPU processor can expand the performance and capacity of security system and meet the needs of future information development.

4. High availability and reliability: The application security system must be able to work continuously for a long time. Reliability can usually be measured by MTBF (mean time between failure). Redundancy technology can improve the reliability of the whole system. Such as redundant backup power supply, redundant backup network card, ECC memory, ECC protection system bus, RAID disk array technology, server automatic recovery, etc.
