Embodiment Construction

[0027] The solutions provided in this specification will be described below in conjunction with the accompanying drawings.

[0028] At present, the BMC is integrated in the main board of the server. After a small system failure of the BMC, the BMC can be reset by pressing and holding the UID (unit identification light) button. The business is migrated and the whole server is powered off for maintenance. This maintenance method takes a long time and costs a lot.

[0029] Based on this, the embodiment of this specification pioneeringly proposes a BMC online hot maintenance solution that does not affect services. This scheme includes hardware realization part and software realization part. In the hardware implementation part, the BMC is modularized so that it can be set independently from the server main board and can be hot-swappable. Specifically, the following describes the solution for the hardware implementation from three perspectives: the BMC module, the server main boar...

Abstract

The embodiment of the invention provides a server management system. The server management system comprises a server mainboard and a baseboard management controller (BMC) module, wherein the BMC module and the server mainboard are independently arranged; the BMC module and the server mainboard are respectively connected in a pluggable manner through a first interface and a second interface of the BMC module and the server mainboard; the BMC module is provided with a power supply slow start circuit which is used for supporting power supply protection when the BMC module is hot-plugged relative to the server mainboard; the server mainboard is provided with a signal isolation circuit which is used for supporting signal isolation when the BMC module is in hot plug relative to the server mainboard.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computer technology, and in particular to a baseboard management controller BMC module, a server motherboard, a server management system, and a thermal maintenance method and system for a baseboard management controller BMC module. Background technique [0002] BMC (baseboard management controller, baseboard management controller) is used in the server system to monitor and manage the server fan, power supply, and equipment presence. The BMC has data interaction with the CPU. [0003] At present, if the BMC fails, the service needs to be stopped and the entire server needs to be taken offline for maintenance, resulting in a long maintenance cycle and high costs. Based on this, the embodiment of this specification pioneeringly proposes a BMC online hot maintenance solution that does not affect services. Contents of the invention [0004] One or more embodiments of this specification...
