Circuit supporting automatic switching of NCSI signal management function and server

Abstract

Embodiments of the invention disclose an NCSI signal management function switching circuit and a server. The circuit comprises a BMC chip, a high-speed signal Switch chip, a first network adapter device and a second network adapter device, and an NCSI signal of the BMC chip is connected with the first network adapter device and the second network adapter device separately through the high-speed signal Switch chip. The high-speed signal Switch chip has a channel switch enabling PIN, a second network adapter device present signal is connected with the channel switch enabling PIN of the high-speed signal Switch chip, so as to control high and low levels of the channel switch enabling PIN of the high-speed signal Switch chip, so that the NCSI signal link can be connected or disconnected, further, the NCSI signal of the BMC can select the channel to the first network adapter device and the second network adapter device. The circuit can automatically switch the NCSI management function, improve the self-adaptability and reliability of the network management function, realizes out-of-band management of the server, and is convenient to operate and maintain.

Description

technical field [0001] The invention relates to the field of server mainboard manufacture and inspection. Background technique [0002] With the rapid development of the Internet economy, the business of data centers continues to grow, and the number and scale of data centers increase rapidly, which puts forward higher requirements for out-of-band manageability and controllability of servers. [0003] Flexibility and reliability are a very important indicator requirement. Through out-of-band management, engineers can connect to the corresponding server through the network at any location to perform a series of management and maintenance, without having to stay in a noisy laboratory environment for a long time. NCSI (Network Controller Sideband Interface) is an industry standard for sideband interface network controllers defined by the Distributed Management Task Force to support server out-of-band management. [0004] At present, the conventional design method of server ma...

AI Technical Summary

Problems solved by technology

[0005] The design method of switching and selecting the NCSI signal management function through the BMC FW selection setting needs to modify the FW according to the application environment to realize the switching of the NCSI signal management function, which lacks flexibility.
