Abstract: This application discloses a fan box, a server system, and a method for adjusting a rotation speed of a fan box, and belongs to the field of server heat dissipation technologies. The fan box provided in embodiments of this application has a plurality of communication interfaces, and each communication interface can be electrically connected to one server board. Therefore, the fan box provided in embodiments of this application can be electrically connected to a plurality of server boards. In addition, a controller in the fan box can adjust a rotation speed of a fan based on a plurality of fan box speed adjustment instructions. Therefore, the fan box provided in embodiments of this application can be controlled by a plurality of master control nodes, and is applicable to a multi-node server system with a central management unit-free architecture, and any server system that requires multi-node master control.

Abstract: Computer devices and management methods are provided. In an implementation, a computer device includes a subrack common component and a plurality of service nodes, wherein each of the plurality of service nodes comprises a baseboard management controller (BMC connected to the subrack common component and configured to manage the subrack common component when being in a primary status.
