摘要:
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.

A computer system and an operation system loading method thereof are provided. The computer system comprises a universal serial bus (USB) storage device storing a boot image, servers and a boot image sharer comprising USB ports, a memory, a first USB host controller and a micro-processor. The micro-processor controls the first USB host controller to emulate each USB port to the USB storage device, and stores the boot image to memory, such that the boot image is shared to the USB ports. The servers are respectively coupled to the USB ports, wherein each server comprises a second USB host controller and a basic input output system (BIOS). The second USB host controller is coupled to one of the USB ports. The BIOS reads the boot image from the emulated USB storage device and loads an operation system according to the boot image.

A server cluster including a network switch and multiple server nodes is provided. The network switch is connected to an external network. Each server node includes a network port, a network chip and a control unit. The network port is connected to the network switch via a cable. The network chip detects the cable to obtain a connection state with the external network at the server node after the network switch is started, and accordingly outputs a connection state signal. The control unit turns on or shuts down the server node according to the connection state signal and an on/off state of the server node.

A computer system and a diagnostic method thereof are provided. The computer system comprises a system management bus (SMBus) switch, a plurality of servers and a remote management controller (RMC). Each server comprises a diagnostic message port, a basic input output system (BIOS) and a logic circuit. The BIOS outputs a diagnostic message to the diagnostic message port. The logic circuit catches the diagnostic message. The RMC comprises a SMBus host controller. The SMBus host controller controls the SMBus switch to connect the SMBus host controller to a corresponding logic circuit according to a request. The logic circuit responds the diagnostic message to the SMBus host controller according to the request.

A server cluster including a network switch and multiple server nodes is provided. The network switch is connected to an external network. Each server node performs an operation system and respectively includes a network port, a network chip and a south bridge chip. The network port is connected to the network switch via a cable. The network chip outputs a power-off signal according to a received power-off packet after the network switch is started. The south bridge chip outputs a shutdown signal to shut down the server node according to the power-off signal when the server node is turned on and the operation system is working normally.
