A server node position identification system

The invention discloses a position identification system of a server node. The position identification system comprises a reference signal output module used for outputting a first signal; Tcontrollers arranged in the N server nodes, wherein the signal input end of the first controller is connected with the output end of the reference signal output module, the signal output end of the i controlleris connected with the signal input end of the i + 1th controller, and the signal output end of the N controller is suspended; Wherein i is greater than or equal to 1 and less than N, and N is an integer not less than 2; The ith controller is used for determining the position of the ith controller according to the characteristic of the ith signal and a preset characteristic position correspondingrelation when the ith signal is received, and outputting an i + 1th signal to the i + 1th controller; And the Nth controller is used for determining the position of the Nth controller according to thecharacteristic of the Nth
