Device and method for remotely managing server system BMC

Abstract

The invention provides a device and method for remotely managing a server system BMC. A mainboard BMC adopting a node mainboard is connected to a CPLD of a CMC management module through a UART5; the CPLD has the functions of UART protocol analysis and interface switching. The mainboard BMC is connected to a UART3 port of a management BMC in the CMC management module through a UART; the managementBMC is linked to an external network; the management BMC has a network function and an SOL function. The scheme in which the number of the node mainboards is at least eight can solve the technical problems that in the prior art, a node cannot be connected with a BMC management control serial port on line in a case and can be used only when arriving; remote link of the management serial port of theBMC of the mainboard is achieved, the mainboard BMC can be accessed without arriving at the site, and the technical effect that the server mainboard BMC can be managed in a unified mode can be achieved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a device and method for remotely managing a BMC of a server system. Background technique [0002] In order to save space, most of the current servers adopt the design of high-density node whole machine system in order to reduce space and energy consumption. The high-density node complete machine system includes a chassis, multiple server node mainboards, backplanes, a complete machine management module, external devices on the mainboard, etc. Due to the limited structural space, some directly connect the BMC control UART of the main board of the server node to the interface outside the chassis, or just pull the BMC serial port of the main board to the outside of the chassis, and in order to save space, there are various types of interfaces. Uniform standards. [0003] At present, the high-density node server cannot connect the management control serial port of the BMC of each node moth...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a kind of device and method of remote management server system BMC, adopt the main board BMC of node main board to be connected to the CPLD of CMC management module through UART5, described CPLD has the function of analyzing UART agreement and interface switching, described main board BMC is connected to the CPLD of CMC management module through UART Receive the UART3 port of the management BMC in the CMC management module, the management BMC is linked to the external network, the management BMC has network and SOL functions, and the node main board has at least 8 solutions, which solves the problem in the prior art It is impossible to realize the technical problem that the node can be connected to the BMC management control serial port online in the chassis, and must arrive at the site to use it.
