Abstract: A server system includes a rack, a power supply module, a switch, and a plurality of servers. The rack can be divided into a plurality of rack units. The rack units are parallel to each other and vertically arranged. The power supply module and the switch are disposed in close proximity to each other in at least one of the rack units. The power supply is adjacent to the rear side of the rack. The switch is adjacent to the front side of the rack. Each of the servers is disposed in one of the other rack units and electrically connected to the power supply module and the switch.

Abstract: A rack server system controlled by a remote controller includes a number of server units and a middle plane board. Each of the server units includes a baseboard management controller (BMC), a server-end connector, and a server-end switch, coupled to the BMC and the server-end connector for regulating communication operation therebetween. The middle plane board includes an integrated connector and a plane-end switch, coupled to the server-end switches of each of the server units and the integrated connector for regulating communication operation thereamong. The remote controller is coupled to the rack server system via one of the integrated connector and the server-end connectors and manages the communication operation of the server units.

Abstract: A rack server system includes a number of server units and a rack. The rack server includes a back plane, a control module, a fan module and a power supply module. The back plane includes a number of slots, via which the server units are respectively connected to the back plane. The fan module is connected to the control module, and dissipates heat generated by the server units under the control of the control module. The power supply module is connected to the control module, and powers the server units under the control of the control module.

Abstract: A rack system for a server includes a number of server units, which includes first to the third sets of server units, voltage converter, first to third power supply circuits. The voltage converter receives and converters a three-phase alternating current (AC) power signal to provide first to third single-phase power signals. The first to the third sets of power supply circuits respectively provides first to third direct current (DC) power signals according to the first to the third single-phase power signals. The first set to the third set of server units is respectively powered by first to the third DC power signals or respectively powered by first part, second part, and third part of the first to the third DC power signals.

Abstract: A power management module for a memory module is provided. The memory module is coupled to a chipset. The power management module includes a basic input/output system (BIOS), a power regulation module, and a DC-DC converter module. The BIOS is coupled to the chipset, and contains a power consumption data of the memory module. The power regulation module is coupled to the BIOS, and is adapted for outputting a power control signal according to the power consumption data of the memory module. The DC-DC converter module is coupled to the memory module and the power regulation module. The DC-DC converter module includes a plurality of DC-DC converters, and is adapted to determine a quantity of the DC-DC converters for enabling according to the power control signal, so as to provide a suitable power to the memory module.

Abstract: A power management module for a CPU is provided. The power management module includes a basic input/output system (BIOS) chip, a power stripping module, and a DC-DC converter module. The BIOS chip is coupled to the CPU, and has a power consumption information of the CPU. The power stripping module is coupled to BIOS chip, and is adapted for outputting a power control signal according to the power consumption information of the CPU. The DC-DC converter module is coupled to the CPU and the power stripping module. The DC-DC converter module includes a plurality of DC-DC converters. The power control signal is accorded to determine a quantity of the DC-DC converters for enabling, so as to provide a suitable power to the CPU.
