  • Publication number: 20140122753
    Abstract: An electronic device, a management method thereof, and a rack serving system are presented. A management interface packet is transferred to a second connection port of a storage interface through a first connection port of a baseboard management controller (BMC). Also, a hard disk drive (HDD) controller of the storage interface converts the management interface packet into an internal control command that conforms to the storage interface, so as to read the system environment information according to the internal control command. Additionally, the HDD controller encapsulates the system environment information into a response packet, and transfers the response packet to the first connection port of the BMC through the second connection port.

  • Publication number: 20140122910
    Abstract: An operation method of a rack server system includes receiving power information for each of a plurality of nodes, calculating a maximum power consumption value of the rack server system and a total power consumption value of the nodes upon the power information, determining whether a ratio value between the maximum power consumption value and the total power consumption value exceeds a predetermined ratio value and adjusting operation statuses of the nodes, for making the rack server system enter a power saving mode when the ratio value does not exceed the predetermined ratio value. Further, a rack server system includes multiple nodes and a rack management controller. The nodes include a power supply, a base board management controller coupled to the power supply and a connection interface coupled to the baseboard management controller. The rack management controller is coupled to the baseboard management controller through the connection interfaces.

  • Publication number: 20120131361
    Abstract: A remote controller is connected to one or more server via an intelligent platform management bus (IPMB). The controller includes a redundant power supply and a remote control module. Once the remote controller receives a control command to power on one of the servers from a system administer, the remote control module powers on the server, and sends an operation command to control a motherboard of the server to run. By utilizing the remote controller, the system administrator can remotely control baseboard management controllers of the servers when the power supply of the server does not have an AC power.
