Abstract: A rack management system and a rack management method thereof are disclosed; wherein the storage management system is used for managing a plurality of chassis. The storage management system includes a rack, a resistor cable, a power supply module, a detection module, and a processing module. The rack has a plurality of storage portions for disposing the plurality of chassis respectively. The resistor cable is disposed in the rack for corresponding to each storage space. The power supply module is used for supplying a power signal to the resistor cable. When the plurality of chassis is disposed in the plurality of storage portions, the detection module detects the resistor cable to generate a plurality of detection signals. The processing module records locations of the plurality of chassis based on the plurality of detection signals.

Abstract: A server management system disposes two wave generators on a rack and disposes a wave sensor on a server, wherein each of the wave generators is capable of emitting an omni-directional wave and a directional wave. When the wave sensor senses the omni-directional wave and the directional wave at different time points, one of the server and a host device is capable of determining two angles of the wave sensor relative to the two wave generators according to time differences and then calculating a position of the server located in the rack according to the two angles.
