In the prior art, the NTB chip is directly integrated on the mainboard in the case, and then the related wiring arranged on the mainboard is relied on as the NTB link to realize high-speed communication between the controllers in the case.

[0053] In addition, when the number of cable plug-in ports included in the second plug-in module is multiple, the control module can be connected with each cable plug-in port to determine whether a high-speed signal transmission cable is inserted into each cable plug-in port. More specifically, the control module can include a switch corresponding to each cable plug-in port, and when a cable is inserted into a certain cable plug-in port, the corresponding switch is opened so that the control module receives a first signal representing that the port has a cable inserted; when a cable is not inserted into a certain cable plug-in port, the corresponding switch is closed so that the control module receives a second signal representing that the port has no cable inserted, and the judgment logic for whether a cable is inserted or not includes but is not limited to the above-mentioned manner, which is not particularly limited here.

This scheme relies on the flexible arrangement of high-speed signal communication cables, the high-speed signal communication cables can be flexibly plugged, cross-device high-speed communication is realized, deployment is simple and convenient, and the application of the NTB chip is not limited to one device, which greatly improves the convenience of communication link connection between master modules in different electronic equipment, expands the application of the NTB chip, and has stronger applicability and practicality.

[0057] On the basis of the above-mentioned embodiments:

[0058] As a preferred embodiment, the electronic equipment further includes a mainboard, and the B master modules are arranged on the mainboard.

[0059] When B is an integer greater than 1, any two master modules are further connected through a preset high-speed transmission line arranged on the mainboard for high-speed communication.

[0060] In this embodiment, considering that the B master modules are arranged on the mainboard, a preset high-speed transmission line for high-speed communication can be arranged on the mainboard in advance, and for multiple master modules in any electronic equipment, high-speed communication can be realized by means of the preset high-speed transmission line, Figure 1For example, B=3, and for the master module L1, the master module L2 and the master module L3, the master module L1 and the master module L2, the master module L1, the master module L3 and the master module L2, and the master module L3 are connected through the corresponding preset high-speed transmission lines to realize high-speed data communication transmission.

[0061] As a preferred embodiment, any high-speed communication auxiliary device in any electronic device further comprises:

[0062] A temperature acquisition module connected with the control module, configured to acquire temperature information corresponding to the high-speed communication auxiliary device, so that the control module controls the heat dissipation module to dissipate heat based on the temperature information.

[0063] And / or,

[0064] A voltage conversion module, an input end of which is connected with the power supply, and output ends of which are respectively connected with a power supply end of the NTB chip and a power supply end of the control module, configured to convert voltage, so as to supply power to the NTB chip and the control module.

[0065] In the embodiment, further considering that the high-speed communication auxiliary device can further comprise a temperature acquisition module and / or a voltage conversion module, the temperature acquisition module can acquire temperature information corresponding to the high-speed communication auxiliary device, the heat dissipation module can be a heat dissipation module in the high-speed communication auxiliary device, or can be a heat dissipation module configured in the electronic device, such as a fan, which is not particularly limited here; more specifically, a temperature-speed corresponding relationship can be set in advance, and then the fan can be controlled to operate at a target speed corresponding to the current temperature information to achieve heat dissipation.

[0066] Considering that the power supply requirements of the control module and the NTB chip can be different, the voltage conversion module can be set to convert the voltage input by the power supply, so as to supply power to the two, to ensure their reliable work.

[0067] Of course, in combination with the actual application, the high-speed communication auxiliary device can further comprise other design modules, such as a prompt indicator light for prompting whether the cable is in place, which is not particularly limited here, and can be determined according to actual needs.

[0068] As a preferred embodiment, the high-speed signal transmission cable is a miniSAS cable.

[0069] In the embodiment, in order to realize standardized management, the high-speed signal transmission cable can adopt a miniSAS cable, which can meet the requirements of high-speed communication transmission, has the advantages of low loss, small size, strong anti-interference ability, etc., and is beneficial to realize the functions of the high-speed signal transmission cable in the application.

[0070] In addition, it should be noted that in actual applications, the two electronic devices can be placed as close as possible to shorten the length of the required miniSAS cable and ensure the reliability of high-speed signal transmission.

[0071] As a preferred embodiment, the total number of connected high-speed signal transmission cables is N, and the transmission performance of the N high-speed signal transmission cables is independent of each other, and N is an integer not less than 1.

[0072] In this embodiment, it is shown that the number of high-speed signal transmission cables can be multiple, that is, the high-speed communication auxiliary device in any electronic device can be connected to the high-speed communication auxiliary device in another electronic device through N high-speed signal transmission cables, N is an integer not less than 1; and the decoupling design between each high-speed signal transmission cable is used to make the transmission performance of each high-speed signal transmission cable independent of each other, and eliminate the mutual influence between the cables. Please further refer to Figure 1 , Figure 1 In the high-speed communication auxiliary module G1 and the high-speed communication auxiliary device G3, two high-speed signal transmission cables are used, that is, the first port 231 in the high-speed communication auxiliary module G1 is connected to the first port 231 in the high-speed communication auxiliary module G3, which is the first high-speed signal transmission cable; the second port 232 in the high-speed communication auxiliary module G1 is connected to the second port 232 in the high-speed communication auxiliary module G3, which is the second high-speed signal transmission cable; the reason for such arrangement is to consider the needs of redundancy backup and bandwidth expansion. From the perspective of bandwidth expansion, the equivalent bandwidth corresponding to one miniSAS cable is x4, and the equivalent bandwidth corresponding to two miniSAS cables is x8, so the theoretical value of the communication transmission capacity of the master module 31 and the master module 33 can reach 7.8GB / s, which guarantees the data transmission capacity; from the perspective of redundancy backup, the first high-speed signal transmission cable and the second high-speed signal transmission cable are independent of each other, even if one of the high-speed signal transmission cables fails, the other high-speed signal transmission cable can still be used to avoid the interruption of high-speed communication between the corresponding master modules, which is more beneficial to practical application. It should be noted that, Figure 1The preset high-speed transmission line between the master module 31 and the master module 32 can also adopt the above-mentioned redundant backup wiring form, and the same applies to the master module 33 and the master module 34, which are not particularly limited here. It can be understood that the first port 231 and the second port 232 in the above-mentioned high-speed communication auxiliary module G1 can be logically considered as being virtually one port (the corresponding equivalent bandwidth is x8) to realize high-speed communication with the high-speed communication auxiliary module G3; the third port 233 and the fourth port 234 in the above-mentioned high-speed communication auxiliary module G1 can also be logically considered as being virtually one port (the corresponding equivalent bandwidth is x8) to realize high-speed communication with the high-speed communication auxiliary device G4. The ports of each second plugging module 23 in the high-speed communication auxiliary module G2, the high-speed communication auxiliary module G3 and the high-speed communication auxiliary module G4 are the same, and details are not repeated here.

[0073] It can be seen that through the above-mentioned setting, the reliability of high-speed data transmission is better guaranteed, which is beneficial to practical application and realizes the compatibility of high-speed communication performance and communication stability.

[0074] Please refer to Figure 2 , Figure 2 for the flowchart of the high-speed communication control method provided by the application.

It should be noted that the preset link configuration component is determined according to a standard PCIe connection specification, and a component program corresponding to the specification determines whether the condition is met, and link is realized.

[0080] For S52, the specific execution logic can be: determining a target configuration bandwidth based on the total number of connected high-speed signal transmission cables and a preset number-bandwidth correspondence relationship, and configuring the NTB chip according to the target configuration bandwidth, so that the host module corresponding to the control module itself realizes high-speed communication with the target host module corresponding to the target second plugging module through the NTB chip and the high-speed signal transmission cable.

[0082] When it is determined that the second plugging module in the high-speed communication auxiliary device where the control module is located and the target second plugging module are in a connected state and that the connected high-speed signal transmission cable is pulled out, determining the number of remaining high-speed signal transmission cables that are not pulled out and connected;

[0083] Determining a first target bandwidth corresponding to the number of high-speed signal transmission cables that are not pulled out and connected based on the number and a preset number-bandwidth correspondence relationship;

[0084] Reconfiguring the NTB chip based on the first target bandwidth, so that the host module corresponding to the control module itself realizes high-speed communication with the target host module corresponding to the target second plugging module through the NTB chip and the remaining high-speed signal transmission cable.

[0085] In this embodiment, the cable pull-out execution logic when the high-speed communication auxiliary device implements the cable hot plug function is given. Specifically, after determining that the second plug-in module in the high-speed communication auxiliary device where the self is located and the target second plug-in module are in a connected state and have completed the current NTB chip configuration, if one or more cables are pulled out in the connected state, the number of connected cables that are not pulled out is determined. For example, if the total number of connected cables is 2 and one cable is pulled out, then the number of connected cables that are not pulled out is 1. Based on the number of connected cables that are not pulled out and the preset quantity-bandwidth correspondence relationship, the first target bandwidth corresponding to the number of connected cables that are not pulled out is determined, wherein the preset quantity-bandwidth correspondence relationship includes but is not limited to the quantity 1-bandwidth x4, the quantity 2-bandwidth x8, the quantity 3-bandwidth x12, and the like. Finally, based on the first target bandwidth, the NTB chip is reconfigured, the hardware layer link down is cleared, and the scene is cleaned, so that the corresponding master module of the self realizes high-speed communication with the target master module corresponding to the target second plug-in module through the NTB chip and the remaining high-speed signal transmission cable. For example, in the above case, the first target bandwidth is x4, the original bandwidth x8 is reduced to the first target bandwidth x4, and the NTB chip is configured.

[0086] It can be seen that through the above setting, the bandwidth automatic reduction configuration logic when the connected cable is pulled out is realized to realize the cable hot plug, and the automatic dynamic connection configuration between the master modules in different electronic devices is realized, which is beneficial to practical application.

[0087] As a preferred embodiment, it further includes:

[0088] When it is determined that the second plug-in module in the high-speed communication auxiliary device where the self is located and the target second plug-in module are in a connected state and there is a newly added high-speed signal transmission cable connected, the sum of the number of newly added high-speed signal transmission cables and the total number of originally connected high-speed signal transmission cables is determined as the number of cables to be configured.

[0089] Based on the number of cables to be configured and the preset quantity-bandwidth correspondence relationship, the second target bandwidth corresponding to the number of cables to be configured is determined.

[0090] The preset link configuration component is used to determine whether the condition of expanding the original bandwidth to the second target bandwidth is met, and the original bandwidth is the bandwidth corresponding to the total number of connected cables.

[0091] If yes, the NTB chip is reconfigured based on the second target bandwidth, so that the corresponding master module of the self realizes high-speed communication with the target master module corresponding to the target second plug-in module through the NTB chip and all currently connected high-speed signal transmission cables.

[0092] In this embodiment, the cable insertion execution logic when the high-speed communication auxiliary device implements the cable hot plug function is further given. Specifically, after determining that the second plugging module in the high-speed communication auxiliary device in which the high-speed communication auxiliary device is located and the target second plugging module are in a connected state and have completed the current NTB chip configuration, if there is one or more newly added cables connected in the connected state, the number of newly added high-speed signal transmission cables is determined, the number of newly added high-speed signal transmission cables is added to the total number of connected cables, and the sum is the number of cables to be configured. For example, if the total number of connected cables is 2 and one cable is newly added, the number of cables to be configured is 3.

[0093] Based on the number of cables to be configured and the preset number-bandwidth correspondence relationship, the second target bandwidth corresponding to the number of cables to be configured is determined. Whether the condition of expanding the original bandwidth to the second target bandwidth is met is determined by using a preset link configuration component. The preset link configuration component is determined according to the standard PCIe connection specification. The component program corresponding to the specification can determine whether the condition is met, and actively implement link. Specifically, the step is: using the preset link configuration component to attempt link. If the link is successful within a preset number of times, it is determined that the condition of expanding the original bandwidth to the second target bandwidth is met. The preset number of times includes but is not limited to 3 times. If the link is not successful within the preset number of times, it means that the bandwidth expansion fails, and there may be internal interruption or other faults in the cable. Therefore, the current original bandwidth is still maintained for communication.

[0094] Finally, when it is determined that the condition is met, the NTB chip is reconfigured based on the second target bandwidth, the hardware layer is linked up, and the connection is established, so that the corresponding host module of the high-speed communication auxiliary device realizes high-speed communication with the target host module corresponding to the target second plugging module through the NTB chip and all connected high-speed signal transmission cables. For example, in the above case, the second target bandwidth is x12, the original bandwidth x8 is expanded to the second target bandwidth x12, and the NTB chip is configured.

[0095] It can be seen that through the above setting, the bandwidth automatic expansion configuration when the newly added cable is connected is realized to realize the cable hot plug, and the automatic dynamic connection configuration between the host modules in different electronic devices is realized, which is beneficial to practical application.

[0096] As a preferred embodiment, the total number of connected high-speed signal transmission cables is N, and N is an integer not less than 1.

[0097] The high-speed communication control method further includes:

[0098] For any one of the high-speed signal transmission cables connected in the second plugging module, the following steps are performed:

[0099] determine whether the heartbeat monitoring data corresponding to the high-speed signal transmission cable is not updated within a preset monitoring duration, the heartbeat monitoring data being sent by a control module corresponding to the target second plugging module based on a preset monitoring period through the high-speed signal transmission cable, the preset monitoring period being less than the preset monitoring duration;

[0100] If yes, output a prompt signal representing that the high-speed signal transmission cable has failed.

[0101] In the embodiment, the monitoring logic of each connected high-speed signal transmission cable is given after it is determined that the second plugging module in the high-speed communication auxiliary device in which the self is located and the target second plugging module are in the connected state and have completed the current NTB chip configuration. Specifically, two ports connected at two ends of each high-speed signal transmission cable correspond to a heartbeat monitoring data. Assuming that the two ports are port O1 and port O2, the port O1 sends a new heartbeat monitoring data to the port O2 every preset monitoring period to update the old heartbeat monitoring data stored in the port O2. Similarly, the port O2 sends a new heartbeat monitoring data to the port O1 every preset monitoring period to update the old heartbeat monitoring data stored in the port O1. On this basis, for any high-speed communication auxiliary device in any electronic device, for any high-speed signal transmission cable connected in the second plugging module, it is determined whether the heartbeat monitoring data corresponding to the high-speed signal transmission cable is not updated within a preset monitoring duration. If no, the monitoring can be continued. If yes, it is indicated that the current high-speed signal transmission cable has failed, and a prompt signal representing that the high-speed signal transmission cable has failed is output. Of course, the high-speed signal transmission cable can be directly identified as being pulled out, and the bandwidth configuration is actively reduced. No particular limitation is made herein, and it is determined according to actual needs.

[0102] It can be seen that the above setting further ensures the reliable monitoring of the connected high-speed signal transmission cable, facilitates the timely discovery of the failed cable, and quickly locates the failure.
