Description

TECHNICAL FIELD

[0001] The utility model relates to the field of server management, especially to a server realizing flexible configuration of management network port and a server management system. BACKGROUND

[0002] The server is the computer equipment widely used in data center, cloud computing, enterprise storage and industrial control. In addition to the external internet data channel for communicating with the Internet, the server also has internal management network data channel. The internal management network data channel is also called external network card or out-of-band interface, which is connected to the BMC or other management card on the server mainboard through the management port, and the server is remotely managed and monitored through the remote management protocol. The management port has an independent IP address and MAC address, and the server can be managed through remote access. The management network generally takes BMC as the management core in the server, and is converted into RJ45 interface form through a network chip.

[0003] The commonly used management board in the current server is DC-SCM board, which is connected to the mainboard through the golden finger and is generally placed in the rear window position of the server. One of the commonly used schemes is as shown in Figure 5 Two MACs are connected from the BMC chip on the DC-SCM board, one is connected through the RJ45-1 on the board, and the other is connected to the MDI signal connector through the PHY2 interface, and is connected to the RJ45-2 on the left ear plate through the MDI signal connector. Another commonly used scheme is as shown in Figure 6 One MAC is connected from the BMC chip on the DC-SCM board, which is connected to the MDI signal connector through the PHY1, and can be connected to the RJ45-2 on the front window left ear plate through the MDI signal connector, and can also be connected to the RJ45-1 on the board through the MDI signal connector, thereby connecting to the rear window.

[0004] The two commonly used schemes are the conventional design way of the server, although the management network function of the server can be realized, the first scheme needs to output two MAC signals from the BMC, and needs one more set of PHY devices for converting MAC to RJ45 and one more set of PCB wiring, which occupies the mainboard space; the second scheme reduces one set of MAC to PHY conversion and cost, but when using the RJ45 management network port of the rear window, a cable is needed to connect the DC-SCM board and the MDI CONN interface of the left ear plate. In addition, both of the two schemes need to connect the network port RJ45 to the switch through the network cable, and when multiple servers need to be managed, multiple network cables will converge at the switch, and the cable length, layout, fixation and other problems need to be fully considered, which increases the deployment difficulty.
