Multi-node server access method and device, computer equipment and storage medium

Abstract

The invention relates to a multi-node server access method and device, computer equipment and a storage medium, the multi-node server access device comprises a back plate, a power supply unit and a plurality of node plates, each node plate comprises a first processor and a second processor, and the second processor is connected with the back plate through multiple universal input and output channels. The method comprises the following steps: acquiring in-place information of a plurality of node plates; configuration information is obtained from the first processor, and the second processor is controlled to configure universal input and output pin levels corresponding to the node plates according to the in-place information and the configuration information; reading the value of each universal input / output pin and respectively storing the value in a corresponding register; and determining whether the node plate has the access authority of the power supply unit or not according to the in-place information and the values of the plurality of registers in response to the node plate reading the values of the plurality of registers through the plurality of universal input and output channels. By adopting the method, the access conflict problem occurring when multiple nodes access the power supply unit at the same time can be solved.
