20140122753 | Electronic Device, Management Method Thereof, and Rack Serving System - 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. | 05-01-2014 |
20140122910 | RACK SERVER SYSTEM AND OPERATION METHOD THEREOF - 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. | 05-01-2014 |

20140122799 | STORAGE DEVICE AND POWER SAVING METHOD THEREOF - A storage device includes a plurality of hard disk device sets, a plurality of voltage adjustment units, an information collection unit and a control unit. The hard disk device sets access data respectively to generate corresponding access messages. Each of the hard disk device sets includes at least two hard disk devices. The voltage adjustment units determine whether to provide a plurality of duty voltages to the hard disk device sets, according to a plurality of control signals. The information collection unit receives the access messages generated by the hard disk device sets, and outputs the access messages according to a read command. The control unit generates the read command to receive the access messages, acquires the usage states of the hard disk device sets according to an algorithm and the access messages, and generates the control signals according to the usage states of the hard disk device sets. | 05-01-2014 |
20140123121 | RACK AND METHOD THEREOF FOR SIMULTANEOUSLY UPDATING BASIC INPUT OUTPUT SYSTEMS - A rack including a rack management controller and a plurality of server nodes, is disclosed. The rack management controller receives a firmware updating file, and generates an updating message according to the firmware updating file. Each of the plurality of server nodes includes a memory and a baseboard management controller. The memory stores firmware of a basic input output system. The baseboard management controller is coupled to the rack management controller and the memory. The baseboard management controller receives the updating message to download the firmware updating file from the rack management controller and to stores it to a storage space. The baseboard management controller controls the memory to enter a recovery mode after downloading the firmware updating file, and writes the firmware updating file into the memory to update the firmware of the basic input output system. | 05-01-2014 |
20140137095 | SERVER AND METHOD FOR UPDATING FIRMWARE OF SERVER - The disclosure provides a server including a baseboard management controller (BMC), a programmable logic device (PLD) and a blocking unit. The BMC receives an update instruction, and according to the update instruction, generates a firmware update data. The BMC generates an update signal according to on a reception state of the update instruction. The PLD is coupled to the BMC, receives the firmware update data to update a firmware. When the firmware is updated, the PLD generates a restart signal. The blocking unit is coupled to the BMC and the PLD, receives the update signal and the restart signal, and according to the update signal, determines whether to block the restart signal. | 05-15-2014 |
