Problems solved by technology

That is, only a part of the network ports and serial ports are selected for external connection, and the remaining network ports and serial ports are not externally connected but reserved internally. In this way, when the maintenance personnel need to debug the server, they need to open the case and turn on the corresponding The serial port is connected, so it is not convenient for server maintenance

Embodiment Construction

[0033] The core of the present invention is to provide a server and its BMC-based data transmission device, which can use each network port and serial port to conveniently manage and monitor the server, and can avoid the space caused by too many external network ports and serial ports. Restricted question.

[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a BMC-based data ...

Abstract

The invention discloses a data transmission device based on BMC, comprising: N BMC chips; a first MUX for receiving N network signals and outputting a received network signal according to the first control signal; a second MUX used for receiving M + N serial port signals and outputting a received serial port signal according to the second control signal; a third MUX configured to receive a networksignal outputted from the first MUX and a serial signal outputted from the second MUX, and output the received network signal or serial signal to the network interface according to the third controlsignal; a network interface; a control means for transmitting a corresponding first control signal, a second control signal and a third control signal according to the received instruction to determine the source of the output signal of the network interface. The invention also discloses a server, which has corresponding effect. The invention avoids the problem of space limitation caused by the excessive number of external network ports and serial ports.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a server and a BMC-based data transmission device thereof. Background technique [0002] The management and monitoring function of the BMC (Baseboard Management Controller, Baseboard Management Controller) is an important means to ensure the stability of the server. Nowadays, the most commonly used monitoring and management ports of the server are the network port and serial port on the BMC. As the server functions become more and more perfect and the density is higher and higher, multiple BMC management chips may be required in one server, and each BMC management chip is usually equipped with a network port and a serial port to realize corresponding data transmission. In addition, the integrated microprocessors on other boards of the server usually have corresponding serial ports, such as the UART serial port on the SAS controller. The serial port is an important interface for s...
