Abstract:
1. A rack server system, comprising: a rack; a rack management controller comprising a plurality of different first bus ports; a plurality of server groups, each server group comprising a plurality of servers; a plurality of fan modules, each fan module operative to dissipate heat for one of the server groups; and a plurality of fan controllers, each fan controller collecting running information of servers in a corresponding one of the server groups and controlling an operation of a corresponding one of the fan modules accordingly, and each fan controller comprising a plurality of different second bus ports; wherein in each of the server groups, each of the servers is connected to one of the second bus ports of a corresponding fan controller through one of second buses, the servers communicating with the corresponding fan controller using a same second bus address, each of the second bus ports corresponds to a different server position in the rack, wherein the fan controllers communicate with the servers through the second bus ports and acquire server local positions in the rack of the servers in the server group by a difference between the second bus ports through which the communication data is transmitted; wherein each of the fan controllers is connected to one of the first bus ports through one of first buses, the fan controllers communicating with the rack management controller using a same first bus address, and each of the first bus ports corresponds to a different fan controller position in the rack, wherein the rack management controller communicate with the fan controllers through the first bus ports, acquire fan controller positions in the rack of the fan controllers through a difference between the first bus ports through which the communication data is transmitted, and acquire server local positions in the rack of the servers from the fan controllers, so as to acquire the server general positions in the rack of the servers.
