[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0044] See also Figure 1In the prior art, for the design of multiple boards (backplane and Retimer card shown in the figure) in a chassis, since the BMC (baseboard management controller) needs to manage each board uniformly through I2C (bidirectional serial bus), for the separated boards, the BMC (baseboard management controller) and other boards (backplane and Retimer card shown in the figure) are generally connected through a low-speed cable (I2C), and each board is allocated a low-speed cable to monitor, read and write operations on this board. In this way, the BMC (baseboard management controller) must reserve an I2C for each board to be managed to do corresponding management work. When there are many boards, a corresponding number of I2C interfaces are required, resulting in a waste of BMC interfaces. In addition, since the BMC connects each board through cables, when the number of boards is large, it will cause a lot of cables. One is that it occupies the space in the server chassis, which will cause the chassis space to be messy and affect the diversion of the heat dissipation wind. The many cables make it difficult to manage the cables, and the cables are easily damaged, causing quality problems of the whole machine.
[0045] See also Figure 2 In the prior art, for the topology design of high-speed signals, taking PCIE signals as an example, a Retimer card (signal relay device) is used when the line is too long. The Retimer card (signal relay device) is then connected to the backplane through a cable, and then the PCIE disk is inserted into the backplane. In this way, the high-speed signal of the Retimer card passes through the interface to the high-speed cable, then through the cable to the backplane interface, and then from the backplane to the interface of the PCIE disk. After passing through multiple interfaces and the wiring on the backplane, it will cause great loss, which is very unfriendly to high-speed signals.
[0046] In order to solve the above technical problems, the present application provides a server chassis system, which includes: a server mainboard, a backplane and a signal relay device, wherein a controller is arranged on the server mainboard; there are multiple backplanes, and the first ends of the multiple backplanes are connected to the controller through a connecting device; there are multiple signal relay devices, and the first ends of the multiple signal relay devices are connected to the second ends of the multiple backplanes through a connecting device. The use of this system can reduce the number of interfaces and occupy less server space while satisfying the interaction between the controller, the backplane and the signal relay device.

The figure shows that the multiple backplanes include backplane 1, backplane 2, and backplane n.
[0051] Multiple signal relay devices, optionally, the signal relay device can be a Retimer card, which is a signal conditioning chip, and its function is to balance and enhance the signal. It is similar to a PHY chip. When the signal passes through the Retimer card, the signal is reconstructed by the clock inside the Retimer card, which can increase the signal transmission energy, and then continue to transmit, which can improve the reliability of the server chassis system. The figure shows that multiple relay devices include Retimer card 1, Retimer card 2, and Retimer card n.

Among them, the second cable 12 can be a high-speed cable connecting the original backplane and the signal relay device, and the first cable 11 can be an I2C serial communication bus.
[0054] In this embodiment, the connection between the backplane set on the server mainboard and the signal relay device is achieved by borrowing the high-speed cable connecting the original backplane and the signal relay device, and the connection between the controller set on the server mainboard and multiple backplanes is achieved by using low-speed cables. There is no need to additionally set up connecting cables for the connection between the backplane and the signal relay device, and using low-speed cables to achieve the connection between the controller set on the server mainboard and multiple backplanes can also reduce costs.
[0055] Furthermore, in the embodiment, a backplane and a signal relay device are connected in series through an interface, thereby reducing the number of interface arrangements in the server and further releasing available space in the server.
[0056] In this implementation, when the first cable 11 and the second cable 12 can both be high-speed cables, the first cable 11 and the second cable 12 can both be high-speed cables connecting the original backplane and the signal relay device. In this embodiment, by using the high-speed cable connecting the original backplane and the signal relay device to realize the connection between the controller and the backplane and the signal relay device set on the server motherboard, the space occupied by the cables in the server can be reduced, thereby improving the performance of the server.
[0057] And compare Figure 1 In the present application, a plurality of interfaces are arranged on a controller provided on a server mainboard, and are connected to a plurality of backplanes and signal relay devices one by one, that is, one interface corresponds to one backplane or one interface corresponds to one signal relay device. In the present application, a backplane and a signal relay device are connected in series through one interface, thereby reducing the number of interface arrangements in the server and further releasing the available space of the server.

[0095] In the present application, by providing a first crystal oscillator 23, a first pin 27 and a first trigger 25 at the first end of the backplane, and providing a second crystal oscillator 24, a second pin 28 and a second trigger 26 at the second end of the backplane, it is possible to transmit the first baseband signal generated by the first crystal oscillator 23 to the first trigger 25 to obtain a first frequency-divided signal, and transmit the first frequency-divided signal to the first pin 27, and the first pin 27 is connected to the first cable 11, so as to transmit the first frequency-divided signal to the controller on the server motherboard, and the controller on the server motherboard determines whether the first cable is connected correctly according to the first frequency-divided signal; similarly, The second baseband signal generated by the second crystal oscillator 24 is transmitted to the second trigger 26 to obtain a first frequency-divided signal, and the first frequency-divided signal is transmitted to the second pin 28. The second pin 28 is connected to the second cable 12, so that the second frequency-divided signal is transmitted to the control chip on the signal relay device. The control chip on the signal relay device determines whether the second cable is connected correctly according to the second frequency-divided signal. In this way, the detection of multiple cables in a multi-connection device is realized, and the used triggers, crystal oscillators and other components are very small in size, which can further save the internal space of the server chassis on the basis of ensuring the connection reliability of the connection device.
[0096] In this application, the controller set on the server motherboard is connected to the backplane and the signal relay device by using the high-speed cable connecting the original backplane and the signal relay device, which can reduce the space occupied by the cable on the server, save cables, facilitate cable management, facilitate operators to plug and unplug cables, reduce the space occupied by cables in the chassis, reduce the impact of cables on heat dissipation, and release the server system space so that the server system space can be used for other designs. In addition, the I2C interface of the BMC is saved, and the BMC can be used for more complex systems.
[0097] By setting a preset high-speed and low-speed cable to connect the signal relay device, the backplane, and the hard disk device, wherein the sub-high-speed cable in the preset high-speed and low-speed cables does not pass through the backplane, but directly connects the signal relay device and the hard disk device, and the low-speed signals of the signal relay device and the hard disk device are respectively connected to the backplane through the sub-low-speed cables in the preset high-speed and low-speed cables. In this way, the connector on the high-speed signal link and the high-speed signal loss on the PCB (printed circuit board) are saved, and more cables can be introduced, which objectively increases the stability of the high-speed link. Through the above implementation mode, the present application solves the problem of insufficient BMC I2C interface, reduces the cables in the frame, solves the problems of complex cables in the frame, easy damage of cables, and too many cables affecting heat dissipation. It solves the problem that the high-speed link loss is too large and the routing cannot be too long.
[0098] In one embodiment, a temperature detection chip can also be set on the upstream of the server motherboard, and the temperature of each component in the server system can be monitored in real time through the chip. The controller on the server can obtain the temperature information of each component in the server system in real time through the connector and I2C, thereby realizing real-time monitoring of the temperature of each component in the server system, and adjusting the heat dissipation strategy according to the temperature data to reduce power consumption, thereby achieving the purpose of energy saving and environmental protection.
[0099] Among them, the baseboard management controller (BMC) set on the server motherboard obtains the temperature information of each component in the server system through the GPIO reading method or the I2C reading method, thereby realizing real-time monitoring of the temperature of each component in the server system. Exemplarily, the response signal of each I / O interface on each signal relay device can be obtained through the I2C driver chip connected to the motherboard; each interface response signal is parsed to obtain the array corresponding to each I / O interface on each signal relay device.
[0100] In one embodiment, the temperature detection chip can be located at the front end of the server motherboard. The front end of the server motherboard can be the air inlet of the motherboard, and the copper cladding and routing on the motherboard position for wiring and placing the temperature detection chip can be hollowed out to prevent heat from other components from being transferred to the temperature detection chip and affecting the measurement accuracy. The temperature detection chip is installed at this position; the temperature detection chip is connected to the BMC (baseboard management controller) through the I2C channel, and the original data is transmitted to the BMC (baseboard management controller) chip, and the BMC (baseboard management controller) chip performs data correction. In this way, the accuracy of temperature detection can be improved.
[0101] Specifically, the temperature detection chip can obtain the real-time working temperature of each component in the server chassis system, such as the processor on the mainboard, the network switch, etc. during the working process. The I2C bus can determine whether the current working temperature is the working temperature of the server chassis system when it is operating normally based on the working temperature. If the real-time working temperature of a certain component during the working process is not within the normal working temperature range of the server chassis system when it is operating normally, the location information of the component is obtained, a warning message is issued, and it is displayed on the configuration interface.
