At the same time, double disk is recommended. Personally, I don't think Raid is necessary. It is best to use dual disks, and the main hard disk is solid-state hard disk 64G, 128G, 256G, which does not need to be too big. Of course, if the ERP business data of the electronic mall is huge, it is another matter. Thus, the main hard disk is used for system and high-speed operation. The other mechanical hard disk is used for data backup. It is recommended to use 2T or more.
The above configuration does not need to spend too much money, and the PC level is enough. If you run linux and orcal database to realize the operation and management of big data, then a professional server is essential.
For the ERP data volume of general enterprises (except electronic malls and large supermarkets), regardless of the business volume, PC-level server computers can be used as long as the business data volume of odd-numbered products sold annually does not exceed 654.38+billion (excluding the amount) and the number of users operating online synchronously does not exceed 654.38+0000. This can not only ensure the speed, but also achieve a good cost performance.
