Abstract:
1. A server rack system, comprising: a first local area network (LAN) switch, coupled to a management network; a plurality of servers, each having a board management controller (BMC), wherein each of the BMCs has a management network port connected to the management network; at least one power supply unit, for supplying electric power to the server rack system, and having a management network port connected to the management network; and an integrated management module (IMM), having a management network port connected to the management network, and used for visiting the BMCs through the management network to acquire a power consumption value of the servers, wherein the IMM generates a control command according to the power consumption value of the servers, the IMM transmits the control command through the management network to the power supply unit, and the power supply unit adjusts electric power output according to the control command, and wherein the at least one power supply unit comprises: at least one power supply device; and a power controller, coupled to the at least one power supply device, and having a management network port connected to the first LAN switch, wherein the IMM communicates through the management network with the power controller, and controls the at least one power supply device through the power controller, and wherein the power supply unit has a media assess control (MAC) address; the IMM stores an asset mapping table, and the asset mapping table stores a corresponding relation between an asset number and the MAC address of the power supply unit or an MAC address of the BMC of the server; and the IMM acquires the MAC address of the power supply unit or the BMC of the server through the first LAN switch and queries the asset mapping table according to the acquired MAC address so as to obtain the corresponding asset number.
