Rack and method thereof for simultaneously updating basic input output systems

摘要

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.

1. A rack, comprising:
a rack management controller, for receiving a firmware updating file, and generating an updating message according to the firmware updating file; and a plurality of server nodes, each of the plurality of server nodes comprising:
a memory, for storing firmware of a basic input output system; anda baseboard management controller, coupled to the rack management controller and the memory, for receiving the updating message to download the firmware updating file from the rack management controller and store the downloaded firmware updating file in a storage space, and for controlling the memory to enter a recovery mode after downloading the firmware updating file, to write the firmware updating file into the memory so as to update the firmware of the basic input output system; wherein according to the updating message, the baseboard management controller of each of the plurality of server nodes outputs a responding message to the rack management controller, the rack management controller determines whether the responding message is received, if the responding message is received, the corresponding baseboard management controller downloads the firmware updating file from the rack management controller, if the responding message is not received, the rack management controller determines whether a number of times that the responding message is not received is greater than a predetermined value or not, if the number of times that the responding message is not received is not greater than the predetermined value, the rack management controller outputs the updating message to the corresponding baseboard management controllers again, and if the number of times that the responding message is not received is greater than the predetermined value, the rack management controller generates an updating error message.
