Abstract

The invention provides a system and method for realizing server system protection based on a programmable device. A system PCH is connected with a first SPI Flash through a first switch chip. The programmable device is connected with the first switch chip; the programmable device is connected with the second switch chip and is used for controlling and switching paths of the first SPI Flash and thesecond SPI Flash to obtain data of the first SPI Flash and the second SPI Flash and judging the correctness of the data; the programmable device is also connected with a power supply chip, and is used for controlling the power-on time sequence of the power supply chip when judging that the data of the first SPI Flash and the second SPI Flash is correct; the programmable device obtains the data ofthe SPI Flash by switching the path, judges the correctness of the data and then controls the system to be powered on, so that the safety of the whole system can be improved.

Description

technical field [0001] The invention relates to the technical field of server system protection design, in particular to a system and method for realizing server system protection based on programmable devices. Background technique [0002] Programmable devices have been widely used in the design of servers. In the current server system architecture, the data protection mechanism on the server system is becoming more and more important. However, at least one programmable device will be used on the motherboard of the server. , to control the power supply timing of many ICs on the main board. Because of the programmable logic inside the programmable device, many functions can be assembled inside the programmable device. Therefore, how to use the programmable device as a protection mechanism for the server is worthwhile. A well-studied technology. [0003] The current structure of the server is as follows. PCH / BMC will be connected with an external SPI Flash. The data in the F...
