Description

A complete acquisition method, system, terminal and storage medium of a memory serial number

technical field

The invention relates to the technical field of servers, in particular to a method, system, terminal and storage medium for obtaining a complete memory serial number.

Background technique

Memory (Memory) is also called internal memory and main memory. Its function is to temporarily store the operation data in the CPU and the data exchanged with external memory such as hard disks. It is a bridge for other components to communicate with the CPU. All programs are run in memory. As long as the computer is running, the CPU will transfer the data that needs to be calculated into the memory for calculation. When the calculation is completed, the CPU will transmit the result. Therefore, the performance of the memory has a great influence on the computer, and the operation of the memory also determines the computer. Therefore, the use and control of memory modules are particularly important in server manufacturers. It is necessary to record the memory slot and serial number of each server in detail, which is convenient for factory maintenance and positioning, and customer traceability. There are currently two ways to record the serial number of the memory. One is to manually scan during the assembly stage, that is, to develop a corresponding function in the factory's production site management system (SFCS) to prompt the operator to manually scan the label pasted on the memory stick. Obtain the memory serial number and establish a binding relationship with the serial number of the whole machine. The other is to obtain the memory serial number by reading the information in the SMBIOS, but the memory serial number displayed in the SMBIOS is only 8 digits, and the normal memory has 15 or As many as 18 bits, so only 8 bits can't fully locate the memory batch.
