[0030] Combine the following Figure 1-Figure 5 A server cluster system of the utility model is described.

[0031] Figure 1 FIG. 1 is a schematic diagram of a server cluster system according to an exemplary embodiment. Figure 1 and Figure 2 As shown, in an exemplary embodiment, the server cluster system includes multiple servers and at least one connecting line 150, each server includes multiple general processors 110, multiple optical module ports 120, multiple in-position detection modules 130 and multiple indication modules 140, and the optical module ports 120, the in-position detection modules 130 and the indication modules 140 correspond to each other one by one; the general processor 110 is respectively connected to at least one optical module port 120, at least one in-position detection module 130 and at least one indication module 140; the in-position detection module 130 is connected to the corresponding optical module port 120; the connecting line 150 includes an optical fiber connecting line body 152 and two optical modules 151, and the two optical modules 151 are respectively connected to the two ends of the optical fiber connecting line body 152;

[0032] The optical module port 120 is used for inserting the optical module 151;

[0033] The presence detection module 130 is used to detect whether the optical module 151 is inserted into or removed from the optical module port 120;

[0034] The general processor 110 is used to send an indication signal generated based on the connection topology to the indication module 140 of the optical module port 120 corresponding to the optical module 151 at the other end of the connection line 150 after determining through the in-place detection module that the optical module 151 at one end of the connection line 150 is inserted into or removed from the optical module port 120;

[0035] The indication module 140 is used to receive the indication signal sent by the general processor 110, and respond to the indication signal to form indication information.

[0036] In the present utility model embodiment, please refer to Figure 1 and Figure 2 In the server cluster system, multiple servers are arranged. The servers can communicate with each other through a network switch to realize communication between the servers. Each server includes multiple general-purpose processors and multiple optical module ports 120 for inserting optical modules 151. Each optical module port 120 corresponds to an in-position detection module 130 and an indication module 140. The in-position detection module 130 can detect whether the optical module 151 is inserted into or removed from the optical module port 120. Each general-purpose processor 110 is connected to at least one optical module port 120. Figure 2 As shown, one general processor 110 is connected to one optical module port 120 or multiple optical module ports 120 . When the general processor 110 is connected to multiple optical module ports 120 , it can be connected to four optical module ports 120 .

[0037] Specifically, an optical module presence pin ModPrsL is provided in the optical module port 120, and the presence detection module 130 detects the insertion or removal of the optical module 151 by detecting the optical module presence pin ModPrsL in the optical module port 120. When the optical module 151 is inserted into the optical module port 120, the optical module presence pin ModPrsL is at a low level; when the optical module 151 is not inserted into the optical module port 120, the optical module presence pin ModPrsL is at a high level.

[0038] After the general processor 110 determines that the optical module 151 at one end of the connecting line 150 is inserted into or unplugged from the optical module port 120, the indication signal generated based on the connection topology is sent to the indication module 140 corresponding to the connecting line 150. After receiving the indication signal, the indication module 140 responds to form corresponding indication information. The installer can insert or unplug the optical module 151 at the other end of the connecting line 150 into or unplug the corresponding optical module port 120 through the indication information.

[0039] The connecting line 150 is composed of an optical fiber connecting line body 152 and an optical module 151. The optical fiber connecting line body 152 is an optical fiber, and the two ends of the optical fiber are respectively connected to an optical module 151. The optical module 151 and the optical fiber can be connected in a non-detachable manner or in a detachable manner.

[0040] The general-purpose processor 110 is a general-purpose GPU, i.e., a GPGPU (General-Purpose Graphics Processing Unit). By connecting two general-purpose processors 110 via a connecting line 150, data transmission between the two general-purpose processors 110 can be accelerated. Both ends of the connecting line 150 can be inserted into the optical module ports 120 in the same server 100, or can be inserted into the optical module ports 120 in different servers 100.

[0041] Through the technical solution provided by the embodiment of the utility model, an in-place detection module 130 is set to detect whether the optical module 151 of the connecting line 150 is inserted into or unplugged from the optical module port 120. After the optical module 151 at one end of the connecting line 150 is inserted into or unplugged from the optical module port 120, the general processor 110 can directly form indication information at the indication module 140 at the other end of the connecting line 150 through an indication signal to guide the installer to insert or unplug the optical module 151 at the other end of the connecting line 150 into or unplug the optical module port 120. The technical solution provided by the utility model can make the plugging and unplugging of the optical module 151 in the connecting line 150 more intelligent, and there is no need to look up the connection topology to realize the plugging and unplugging of the optical module 151, which saves a lot of time resources. At the same time, the plugging and unplugging of the optical module 151 can be realized by a small number of installers, which saves a lot of human resources and makes the plugging and unplugging maintenance of the optical module 151 easier.

[0042] In an exemplary embodiment of the present invention, please refer to Figure 3 , the server further includes a plurality of I2C control modules 160, each of which corresponds to the optical module port 120, and each of which is connected to the general processor 110 and the optical module port 120;

[0043] The general processor 110 is also used to generate indication information at the other end of the connecting line 150 through the I2C control module 160 after determining that the optical module 151 at one end of the connecting line 150 is inserted into the optical module port 120 and determining that the laser of the optical module 151 is adjustable.

[0044] In an embodiment of the utility model, the server also includes multiple I2C (Inter-Integrated Circuit) control modules. If the optical module 151 at one end of the connecting line 150 is inserted into the optical module port 120, and if the laser emission of the optical module 151 can be adjusted by the I2C control module 160, an indication information connecting line 150 is formed at the other end of the connecting line 150 through the I2C control module 160. The user can insert the optical module 151 at the other end into the corresponding optical module port 120 by checking the indication information at the other end of the connecting line 150 and the indication information of the indication module 140 corresponding to the optical module 151 at the other end of the connecting line 150.

[0045] The optical module port 120 is provided with a TWI (Two-wire Serial Interface) pin, and the I2C control module 160 is connected to the TWI pin.

[0046] If the optical module 151 and the optical fiber cable body 152 are detachably connected, when the optical module 151 at one end of the cable 150 is inserted into the optical module port 120, the optical module 151 at the other end of the cable 150 can be separated from the optical fiber cable body 152, and the laser of the inserted optical module 151 is adjusted through the I2C control module 160 to light up or flash at a specified frequency at the other end of the optical fiber cable body 152. The installer shines the other end of the optical fiber cable body 152 on the card displaying the laser and can see the light spot where the laser lights up or flashes.

[0047] If the optical module 151 and the optical fiber connecting cable body 152 are non-detachably connected, the laser transmitter of the optical module 151 which has been inserted into the optical module port 120 of the connecting cable 150 is controlled by the I2C control module 160, and the optical module 151 at the other end of the connecting cable 150 is connected with the help of a portable device of the optical module manufacturer. The indication information is checked through the receiver connected to the optical module 151 at the other end, so as to determine the light spot where the laser is lit or flashing.

[0048] Through the embodiments provided by the utility model, the installer can determine the corresponding optical module port 120 by checking the indication information at the other end of the connecting line 150 and the indication information of the optical module port 120 corresponding to the optical module 151 at the other end, without the need for the installer to check the connection topology, especially for the scenario where the optical module ports 120 corresponding to the two ends of the connector are far away and there are multiple connecting lines 150.

[0049] In an exemplary embodiment of the present invention, the server cluster system includes a connection line 150;

[0050] The general processor 110 is used to send an indication signal to the indication module 140 corresponding to the optical module 151 at the other end of the connecting line 150 after determining that the optical module 151 at one end of the connecting line 150 is inserted into or unplugged from the optical module port 120; or is used to send an indication signal to the indication module 140 corresponding to the optical module 151 at the other end of the connecting line 150 and the indication module 140 corresponding to the inserted or unplugged optical module port 120 after determining that the optical module 151 at one end of the connecting line 150 is inserted into or unplugged from the optical module port 120.

[0051] In the embodiment of the utility model, when there is only one connecting line 150, an indication signal can be sent to the indication module 140 of the optical module port 120 corresponding to the other end of the connecting line 150, that is, indication information is formed only at the indication module 140 of the optical module port 120 corresponding to the other end of the connecting line 150. When the installer finds which optical module port 120 has the indication information formed, the optical module 151 at the other end of the connecting line 150 can be inserted into or removed from the optical module port 120. Instruction signals can also be sent to the indication modules 140 of the optical module ports 120 corresponding to the optical modules 151 at both ends of the connecting line 150, and the same indication information is formed at the optical module ports 120 corresponding to the optical modules 151 at both ends of the connecting line 150.

[0052] In an exemplary embodiment of the present invention, the server cluster system includes at least two connection lines 150;

[0053] The general processor 110 is used to send an indication signal to the indication module 140 corresponding to the optical module 151 at the other end of the connecting line 150 and the indication module 140 corresponding to the inserted or unplugged optical module port 120 after determining that the optical module 151 at one end of the connecting line 150 is inserted into or unplugged from the optical module port 120; wherein the indication signals corresponding to each connecting line 150 are different.

[0054] In an embodiment of the utility model, when there are multiple connecting wires 150, an indication signal can be sent to the indication module 140 of the optical module port 120 corresponding to the optical modules 151 at both ends of the connecting wire 150, and the same indication information is formed at the optical module ports 120 corresponding to the optical modules 151 at both ends of the connecting wire 150. The installer determines the optical module port 120 corresponding to the optical module 151 at the other end of each connecting wire 150 by comparing the indication information at each optical module port 120.

[0055] Specifically, the general processor 110 determines the indication signal corresponding to each connection line 150 according to the order in which the optical module 151 at one end of the connection line 150 is inserted or removed, such as the indication information formed in response to the indication signal is that the indication module 140 flashes according to the corresponding flashing frequency. When there are n connection lines 150, when generating the indication signal corresponding to each connection line 150, the order of the insertion time or removal time of the optical module 151 at one end of each connection line 150 is arranged, and it is determined that the indication signal of the first inserted connection line 150 is flashing for 1s, interval 10s, then flashing for 1s, and interval 10s cycle; the indication signal of the second inserted connection line 150 is flashing for 2s, interval 10s, then flashing for 1s, and interval 10s cycle; and so on, the indication signal of the nth inserted connection line 150 is flashing for ns, interval 10s, then flashing for ns, and interval 10s cycle. If a new connection line 150 is inserted or removed during the process of plugging or unplugging the optical module 151, the indication signal of the new connection line 150 will continue to be +1 based on n; if all the optical module 151 channels are plugged or unplugged and no new pair is detected, all accumulations will be cleared and n will start from 1.

[0056] In another embodiment of the utility model, a plurality of fixed indication signals may be provided, such as 10, and each indication signal may be consistent with the above, the first indication signal corresponds to the indication signal of the first connecting wire 150, the second indication signal corresponds to the indication signal of the second connecting wire 150, and so on, until the tenth indication signal corresponds to the indication signal of the tenth connecting wire 150. When there are n connecting wires 150, if n is less than or equal to 10, the n connecting wires 150 are matched with corresponding indication signals according to the sequence of insertion time or removal time of the optical module 151 at one end into the optical module port 120; if n is greater than or equal to 10, the n connecting wires 150 are grouped into groups of 10, and those less than 10 are grouped separately, and in each group, each connecting wire 150 corresponds to one of the 10 indication signals. When corresponding indication information is formed at both ends of a group of connecting wires 150, the installer completes the plugging and unplugging of the 10 connecting wires 150, and then displays the indication information corresponding to the next group of connecting wires 150 until the plugging and unplugging of the connecting wires 150 in all groups are completed.

[0057] In the embodiment of the present invention, the above-mentioned setting of the indication signals corresponding to the two ends of the connection line 150 can also control one end of the connection line 150 to respond to the corresponding indication signal through the I2C control module 160.

[0058] In an exemplary embodiment of the present utility model, the indication module 140 includes an indication control submodule and an indication light, and the indication control submodule is connected to the general processor 110 and the indication light respectively.

[0059] In the embodiment of the utility model, the indication module 140 includes an indication control submodule and an indicator light, and the indication control submodule is connected to the general processor 110 and the indicator light respectively. The indication control submodule responds to the indication signal sent by the general processor 110, and displays the result of the response on the indicator light, that is, the indicator light is on or flashes at a corresponding flashing frequency. Specifically, the indicator light can also display different colors of light to distinguish whether the optical module 151 needs to be inserted or unplugged.

[0060] In an exemplary embodiment of the present utility model, the indicator light is disposed at the corresponding optical module port 120 .

[0061] In the embodiment of the utility model, the indicator light is arranged at the corresponding optical module port 120 , so that the installation personnel can confirm the corresponding optical module port 120 according to the indication information.

[0062] In an exemplary embodiment of the present invention, the optical module port 120 includes a light guide column, and the indicator light is connected to the light guide column.

[0063] In the embodiment of the utility model, a light guide column is provided on the outer surface of the optical module port 120, and the indicator light is connected to the light guide column. The light guide column can transmit the light emitted by the indicator light from the indicator light to another point at a certain distance from the indicator light with minimal loss. The light guide column is made of optical grade acrylic or PC sheet, and absorbs the light emitted from the indicator light to stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will diffuse to various angles, and then destroy the reflection condition and be emitted from the front of the light guide column. When the indicator module 140 responds to the corresponding indication signal, the indicator light lights up or flashes at the corresponding flashing frequency. After the light emitted by the indicator light is reflected by the light guide column, the installer can easily determine the corresponding optical module port 120 where the optical module 151 needs to be inserted at the light guide column, and then insert the optical module 151 into the optical module port 120, without the need for the installer to check the corresponding connection topology to determine the corresponding optical module port 120.

[0064] In an exemplary embodiment of the present invention, the optical module port 120 includes an optical module 151 connector.

[0065] In the embodiment of the utility model, the optical module port 120 in the server cluster system adopts an optical module 151 connector, such as a QSFP (Quad Small Form-factor Pluggable) connector. The QSFP connector supports 4 or 8 data transmission channels and can support high-speed data transmission.

[0066] In an exemplary embodiment of the present invention, each server further includes a central processing unit, and the central processing unit is respectively connected to each corresponding general-purpose processor.

[0067] In the present utility model embodiment, please refer to Figure 4 The server further includes a central processing unit 170 (CPU), which is connected to each corresponding general purpose processor 110, and the general purpose processors 110 run together through the central processing unit.

[0068] In the present utility model embodiment, please refer to Figure 5 , the general processor 110 detects a change in the in-place status of the optical module 151 through the in-place detection module 130, determines that the optical module 151 is inserted into or unplugged from the optical module port 120, and initiates an interrupt to the upper-layer driver. The general processor 110 can determine that the optical module 151 at one end of the connecting line 150 is inserted into or unplugged from the optical module port 120. The general processor 110 obtains the in-place status of all optical modules 151, and determines whether the plug-in and unplugging instructions of the optical module 151 are required in combination with the connection topology. Specifically, when the in-place status of the optical modules 151 at both ends of the connecting line 150 is inconsistent, it can be determined that the plug-in and unplugging instructions of the optical module 151 are required. When it is determined that the plug-in and unplugging instructions of the optical module 151 are not required, all indication modules 140 are turned off. When it is determined that the plug-in and unplugging instructions of the optical module 151 are required, the number of connecting lines 150 that require plug-in and unplugging instructions is determined. When there is one connection line 150 that needs guidance, the generated indication signal is sent to the indication module 140 corresponding to the optical module 151 in the connection line 150 whose in-position state has not changed, or is sent to the indication modules 140 corresponding to both ends of the connection line 150 at the same time, or after determining that the optical module 151 in the connection line 150 whose in-position state has changed is inserted into the optical module port 120, and determining that the laser of the optical module 151 is adjustable, the other end of the connection line 150 whose in-position state has not occurred is controlled by the I2C control module 160 to respond to the indication signal. When there are at least two connection lines 150 that need guidance, the generated indication signal is sent to the indication modules 140 corresponding to both ends of the connection line 150 at the same time, so that corresponding indication information is formed at the indication modules 140 corresponding to both ends. The above-mentioned upper-layer driver is a software driver installed under Linux, which can enable the general processor 110 to adapt to the server 100 normally.
