1. A Platform Environment Control Interface (PECI) signal interconnection method for a server, the method comprising:
acquiring a partition mode of the server;
sending a corresponding first control signal and a corresponding second control signal to each computing node of the server according to the partition mode;
controlling a channel selection of a first switch on the corresponding computing node by the corresponding first control signal and controlling a channel selection of a second switch on the corresponding computing node by the corresponding second control signal;
transmitting PECI signals of the corresponding computing node through channels connected by the first switch and channels connected by the second switch;
determining the corresponding computing node that receives the second control signal having a low level as a master node; and
determining the corresponding computing node that receives the second control signal having a high level as a slave node;
wherein controlling the channel selection of the second switch on the corresponding computing node by the corresponding second control signal further comprises;
controlling by the corresponding second control signal, the second switch on the master node to disconnect a first channel of the second switch on the master node from a second channel of the second switch on the master node and connect the first channel of the second switch on the master node with a third channel of the second switch of the master node;
controlling, by the corresponding second control signal, the second switch on the slave node to connect a first channel of the second switch on the slave node with a second channel of the second switch on the slave node and disconnect the first channel of the second switch on the slave node from a third channel of the second switch on the slave node.
