Background technique

With the development of science and technology, information data has grown rapidly, which requires more servers to process information data, which will increase the number of servers in the data center. At present, the deployment scheme of the cabinet used to install the server in the data center is mainly to establish a connection with the switch through a wired method.

When the number of servers increases, it will be more difficult to deploy wired cables. With the widespread application of wireless communications, wireless data centers will become a trend. Normally, the communication between servers in the cabinet is broadcast. The message carries the address information of the target server. All services in the cabinet will receive the message, but the message will be processed only after the target server receives and parses the message. When the server parses the message and learns that the target server is not itself, it will discard the message. The whole process takes up a lot of bandwidth and has a high delay. In addition, the communication of the servers in the cabinet needs to rely on strong wireless signal transceiver equipment to ensure that other servers in the cabinet can receive wireless signals. In order to ensure the communication quality, it is often necessary to deploy multiple transceiver equipment, which will occur between different transceiver equipment. Interference between signals causes the target server to fail to receive the message or delay the message.

In the embodiment of the present application, the transceiver array 113 in the server 110 may form a transceiver array group 140 with a transceiver array 131A in the data exchange device 130. The transceiver array 123 in the server 120 may form a transceiver array group 150 with a transceiver array 131B in the data exchange device 130.

The structure of the server 120 is similar to that of the server 110, and includes a processor 121, a memory 122, and a transceiver array 123.

The structure of the cabinet 200 is similar to the structure of the cabinet 100. The cabinet 200 includes one or more servers. In FIG. 1, two servers in the cabinet 200 are exemplarily drawn, namely the server 210 and the server 220. The cabinet 200 may also include a data exchange device 230. The embodiment of the present application does not limit the number of data exchange devices in a cabinet, and the cabinet 200 may include one or more data exchange devices 230. The data exchange device 230 may include one or more transceiver arrays (the transceiver array 231A and the transceiver array 231B as shown in FIG. 1), and may also include a processor 232 and a memory 234.

Optionally, the data exchange device 230 may also include an external transceiver 233, and the data exchange device 230 may send data to other data exchange devices through the external transceiver 233, such as sending data to the external transceiver in the other data exchange device . Here, other data exchange equipment may be in the cabinet 200 or data exchange equipment in other cabinets, such as the data exchange equipment 130 in the cabinet 100 in FIG. 1.

The relay device 300 is used to implement data interaction between the cabinet 100 and the cabinet 200 and realize data forwarding between the cabinets; the relay device 300 may be The switch can also be a router, or other devices with data exchange functions.

In one cabinet in the embodiment of the present application, the transceiver array in each server and one transceiver array in the data exchange device may form a transceiver array group. Such as the transceiver array group 140, the transceiver array group 150, the transceiver array group 240, and the transceiver array group 250.

Taking the vertical height of the servers in the cabinet 100 as KU as an example, the interval between the transceiver arrays in two adjacent servers is also KU, and the transceiver arrays in the two adjacent servers belong to the transceiver array group The interval of the transceiver array of the data exchange equipment is also KU. For example, if the server 110 and the server 120 in the cabinet 100 are adjacent to each other, the interval between the transceiver array 113 and the transceiver array 213 is KU, and the transceiver array 131A of the data exchange device 130 in the transceiver array group 140 and the transceiver array group 150 The interval of the transceiver array 131B of the data exchange device 130 is also KU.

Taking a transceiver array group 140 as an example, the positional relationship between the transceiver array of the server and the transceiver array of the data exchange device in the transceiver array group will be described.

The relative distance between the transceiver array 113 and the transceiver array 131A in the transceiver array group 140 is D, and D may satisfy the following relationship:

Among them, Y is the maximum signal strength allowed between wireless signals of the same frequency under the premise that there is no interference between wireless signals of the same frequency, and KU is the vertical height of the server. In other words, when D satisfies the above requirements, the data interaction between the transceiver array 113 and the transceiver array 131A suffers less wireless signal interference.

The derivation process of the above formula 1 is as follows:

According to the law of electromagnetic wave propagation in free space, Los=32.44+20lg D+20lg F, where Los is the loss strength of the wireless signal, D is the propagation distance, and F is the frequency of the wireless signal. It can be seen from this law that when the signal strength of the wireless signal is determined, the propagation distance is halved, and the transmit power will be reduced by 6dB.

On the premise that there is no other signal interference between the transceiver array 113 and the transceiver array 131A, there is no signal attenuation, the wireless signals of the same frequency are not interfered and other signal shielding methods are not used, and the wireless signals of the same frequency are allowed The minimum signal strength difference is Y. The embodiment of this application does not limit the specific value of Y. In different wireless transmission scenarios, the value of Y can be different. Y is related to the wireless protocol type, wireless signal characteristics, and transceiver array 131A or transceiver array. The hardware characteristics of the processor array 113 are related.

As shown in Figure 2, the distance between the transceiver array 131A and the transceiver array 113 is D, the distance between the transceiver array 113 and the transceiver array 131B is d, and the distance between the transceiver array 131A and the transceiver array 131B is d. The distance is KU.

The loss strength Los1 of the wireless signal between the transceiver array 113 and the transceiver array 131A, and the loss strength Los2 of the wireless signal between the transceiver array 113 and the transceiver array 131B, need to meet the following conditions:

Los1=32.44+20lg D+20lg F;

Los2=32.44+20lg d+20lg F;

And the difference between Los1 and Los1 should be greater than Y, that is, Los2-Los1≤Y, combining D, d and KU to satisfy the Pythagorean theorem, formula 1 can be obtained. From the description between the transceiver array 131A and the transceiver array 113, it can be seen that there is an association relationship between the transceiver array 131A and the transceiver array 113 in the transceiver array group 140, and the transceiver array 131A and the transceiver array 113 are related to each other. The relative distance between 131A and 113 can enable the transceiver array 131A and the transceiver array 113 to transmit wireless signals, reduce external interference, and effectively improve the transmission efficiency of wireless signals.

In order to ensure that the transceiver array 113 and the transceiver array 131A can exchange data, the data exchange device 130 can allocate the same frequency band to the transceiver array 113 and the transceiver array 131A in the transceiver array group 140, and configure the transceiver array 131A Frequency band; the data exchange device 130 can also inform the server 110 of the frequency band allocated for the transceiver array 113, and the server 110 configures the transceiver array 113 with the same frequency band as the transceiver array 131A.

The processor 132 in the data exchange device 130 may perform frequency band allocation operations and configuration operations, and the processor 111 in the server 110 may configure frequency bands for the transceiver array 113 according to the frequency band allocated by the processor 132 to the transceiver array 113.

Exemplarily, the processor 132 may include a management module 1321 and a management module 1322. The management module 1321 may perform frequency band allocation operations and configuration operations, and the management module 1322 may implement data forwarding operations of the data exchange device 130, as shown in FIG. 7 The operation performed by the data exchange device 130 in step 701 in the method embodiment shown. The processor 111 may include a management module 1111, and the management module 1111 may configure frequency bands for the transceiver array 113.

Similarly, for the transceiver array group 150, the data exchange device 130 can also allocate the same frequency band to the transceiver array 123 and the transceiver array 131B, and configure the frequency band for the transceiver array 131B; the data exchange device 130 can also tell the server 120 to For the frequency band allocated by the transceiver array 123, the server 120 configures the frequency band for the transceiver array 123. For details, please refer to the allocation and configuration of frequency bands of the transceiver array group 140, which will not be repeated here.

For different transceiver array groups, such as the transceiver array group 140 and the transceiver array group 150, the data exchange device 130 can allocate different frequency bands to the different transceiver array groups, for example, the data exchange device 130 can be the transceiver array group 140 The frequency band 0-100MHz is allocated, and the frequency band 200-300MHz is allocated to the transceiver array group 150. After that, the data switch device 130 cooperates with the server 110 and the server 120 respectively to configure the frequency bands of 0-100 MHz for the two transceiver arrays in the transceiver array group 140, and configure the frequency bands of 200 to 200 MHz for the two transceiver arrays in the transceiver array group 150. 300MHz. In this way, different transceiver array groups work in different frequency bands, which can effectively avoid crosstalk of wireless signals interacting in different transceiver array groups.

The foregoing describes the manner in which the data exchange device 130 allocates frequency bands and configures frequency bands to the transceiver arrays in the transceiver array group. The data exchange module 130 can establish the transceiver by allocating frequency bands and configuring frequency bands to the transceiver arrays in the transceiver array group. The association relationship between the two transceiver array groups in the array group.

Optionally, the data exchange device 130 may determine the transceiver array to be associated based on the transceiver array in each server and the location of each transceiver in the data exchange module 130. Optionally, the data exchange device 130 may reduce the relative distance between the transceiver array in the server and the transceiver array in the data exchange module 130 to be less than or equal to a first threshold (for example, the first threshold may be a value determined by Formula 1) The two transceiver arrays to be associated are associated to form a transceiver array group. Among them, the relative distance can be measured by the distance between the adjacent edge points of the two transceiver arrays.

3 is a three-dimensional schematic diagram of a cabinet 100 provided by an embodiment of the application, in which the data exchange device 130 is located on the side of the cabinet 100, the transceiver array 113 in the server 110 in the transceiver array group 150 and the data exchange device 130 The relative distance D of the transceiver array 131A satisfies the foregoing description. If the data exchange device 130 also includes other transceiver arrays, such as the transceiver array 131B, the relative distance D between the transceiver array 131B and the transceiver arrays in other servers also meets the foregoing description.

In the above description, the data exchange device 130 is located on the side of the cabinet 100 as an example. The embodiment of the present application does not limit the location of the data exchange device 130. The data exchange device 130 may also be located on the back side of the cabinet. Moreover, in the cabinet 100 described in FIG. 3, only one transceiver array 131A in the data exchange device 130 is taken as an example for illustration. Exemplarily, multiple transceiver arrays may be arranged in one data exchange device 130 at intervals of KU, where each transceiver array in the data exchange device 130 may be combined with a transceiver array in a server to form a transceiver. Array group, in this way, the data exchange device 130 can perform data interaction with multiple servers.

Generally, the number of servers that can be inserted into a cabinet 100 is fixed. When data exchange equipment is set, multiple data exchange devices can be set on the side of the cabinet 100, where the number of transceiver arrays included in each data exchange device It can be the same or different. Exemplarily, the cabinet 100 is provided with two data exchange devices, namely data exchange device A and data exchange device B, wherein data exchange device A includes three transceiver arrays, and data exchange device B includes two transceiver arrays. ; If the cabinet 100 can be inserted into five servers, namely server 1, server 2, server 3, server 4, and server 5. Among them, server 1, server 2, server 3 requires more frequent data interaction, server 4 and server 5. More frequent data exchange is required between them; server 1, server 2, and server 3 can be inserted into slots opposite to data exchange device A, so that the transceiver arrays in server 1, server 2 and server 3 exchange data with each other One transceiver array in device A is associated, and the two associated transceiver arrays form a transceiver array group. In this way, server 1, server 2, and server 3 can interact through data exchange device A. Server 4 and server 5 can be inserted into slots opposite to data exchange device B, so that the transceiver arrays in server 4 and server 5 are respectively associated with one transceiver array in data exchange device B, and the associated two transceivers The array constitutes a transceiver array group, so that the server 4 and the server 5 can interact through the data exchange device B.

It should be understood that the number of data exchange equipment in the cabinet and the number of transceiver arrays in the data exchange equipment need to match. For example, when each server in the cabinet needs to exchange data with other servers, the number of data exchange equipment in the cabinet and the number of transceiver arrays in the data exchange equipment need to be set to ensure that the transceiver array of each server is at least Corresponds to the transceiver array in a data exchange device.

The following takes the transceiver array 131A in the data exchange device 130 and the transceiver array 113 in the server 111 as an example to illustrate the internal structure of the transceiver array in the data exchange device and the server. The transceiver array is a collection of transceivers, exemplary Yes, the transceiver array 131A may include one or more transceivers. Similarly, the transceiver array 113 may include one or more transceivers, and the transceiver array group 140 may include multiple transceiver groups. The transceiver array group Each transceiver group in 140 includes the transceivers of the transceiver array 113 and the transceivers of the transceiver array 131A. The transceivers of the transceiver array 113 in the transceiver group are associated with the transceivers of the transceiver array 131A. The implementation of this application The example does not limit the number of transceivers included in a transceiver group; for example, a transceiver group may include one or more transceivers of the transceiver array 113 and one or more transceivers of the transceiver array 131A .

One transceiver in the transceiver array 131A or the transceiver array 113 may have both data receiving and sending functions, or only the data receiving function or the data sending function.

In the case that one of the transceivers in the transceiver array 131A or the transceiver array 113 has only one of the data receiving function or the data sending function; for example, one of the transceiver arrays 131A has the data receiving function The transceiver can be associated with a transceiver with a data transmission function in the transceiver array 113 to form a transceiver group; correspondingly, a transceiver with a data transmission function in the transceiver array 131A and one of the transceiver array 113 have The transceivers of the data receiving function are associated to form a transceiver group.

As shown in FIG. 4, it is a schematic diagram of the vertical cross-sectional structure of the front panel of the cabinet in parallel with the transceiver array 113 and the transceiver array 131A in the cabinet shown in FIG. 3, where TX represents a transceiver with a data transmission function, and RX Represents a transceiver with data receiving (receive) function. Only the transceivers of the transceiver array 113 and the transceiver array 131A are shown in the cross section. It should be understood that there is a similar correspondence between the transceiver array 113 and the transceiver array 131A perpendicular to the cross section. Device.

A transceiver TX in the transceiver array 113 can form a transceiver group with a transceiver RX in the transceiver array 131A. For example, the transceiver 1131 in the transceiver array 113 and the transceiver 1311 in the transceiver array 131A form a transceiver group. The transceiver group 141, the transceiver 1133 in the transceiver array 113 and the transceiver 1313 in the transceiver array 131A constitute the transceiver group 143; one transceiver RX in the transceiver array 113 and one transceiver TX in the transceiver array 131A Form a transceiver group, for example, the transceiver 1132 in the transceiver array 113 and the transceiver 1312 in the transceiver array 131A form the transceiver group 142, the transceiver 1134 in the transceiver array 113 and the transceiver 1314 in the transceiver array 131A The transceiver group 144 is formed.

It should be noted that, in the embodiment of the present application, the physical location of the transceivers in a transceiver group may be offset within a certain range on the premise that the transmission communication quality is greater than the threshold. Taking the two transceivers 1133 and the transceiver 1313 in the transceiver group 1403 shown in FIG. 4 as an example, the transceiver 1313 can be located in the bottom surface of a cone with the transceiver 1133 as the top and the height D, and the diameter of the bottom surface is D* Tanθ, where D is the relative distance between the transceiver array 131A and the transceiver array 113, and θ is the direction angle of the wireless signal sent by the transceiver 1133.

When a transceiver group includes more than two transceivers, any transceiver RX in the transceiver group can be located in the bottom surface of a cone with a transceiver TX as the top and a height of D in the transceiver group. The diameter of the bottom surface is D*Tanθ.

In the embodiment of the present application, the arrangement of the transceivers in the transceiver array 131A and the transceiver array 113 is not limited. It only needs to meet the physical positions of the transceiver TX and the transceiver RX in one transceiver group mentioned in the above description can. Optionally, the transceivers with the data receiving function and the transceivers with the data sending function in the transceiver array 131A (or the transceiver array 113) may be arranged at intervals.

As a possible implementation manner, the transceivers in the transceiver array 131A and the transceiver array 113 may be placed in a certain regular manner. For example, they may be regularly arranged in the form of a matrix.

As shown in FIG. 5, it is a schematic diagram of the structure of the transceiver array 131A. The transceivers in the transceiver array 131A are regularly arranged in the form of a matrix; the distance between two adjacent transceivers is equal. Optionally, the transceiver RX with the data receiving function and the transceiver TX with the data sending function are set at intervals.

In the case that the transceivers in the transceiver array 131A are arranged regularly, the physical location of each transceiver in the transceiver array 131A can be identified; for example, the coordinates of the transceivers in the transceiver array 131A can be identified. For the transceiver, for example, a transceiver can be used as the origin of the coordinates, as a two-dimensional coordinate system, and the coordinates of the transceiver at the origin of the coordinates are (0,0); then the gray grid in Figure 5 represents the TX with (0,1) It means that in this way, each transceiver in the transceiver array 131A can correspond to a location identifier. The above location identification is only an example, and the distance between the transceiver and a certain fixed point can also be used as the location identification of the transceiver. The embodiment of this application does not limit the setting method of the location identification, and it can identify the transceiver in the transceiver array 131A. The position of the device is applicable to the embodiments of the present application.

The frequency of the wireless signal received by the transceiver RX with the data receiving function in the transceiver array 131A can be the same or different; similarly, the frequency of the wireless signal received by the transceiver TX with the data sending function in the transceiver array 131A can be the same , Can also be different. In other words, the transceiver array 131A can only be used to transmit wireless signals of a single frequency, or it can be used to transmit wireless signals of multiple frequencies.

The distance B1 between two adjacent transceivers in the transceiver array 131A that receive wireless signals of the same frequency can satisfy the following formula 2:

B1≥D*Tanθ Formula 2

Similarly, the distance B2 between two adjacent transceivers in the transceiver array 131A that transmit wireless signals of the same frequency can satisfy the following formula 3:

B2≥D*Tanθ Formula 3

Where D is the relative distance between the transceiver array 131A and the transceiver array 113, θ is the direction angle of the wireless signal received by the transceiver, and D*Tanθ is the radius of the effective coverage of the wireless signal at the receiving end that is not transmitted.

In other words, the distance between two adjacent transceivers that send (or receive) wireless signals of the same frequency is greater than the radius of the effective coverage of the wireless signal, which can effectively reduce signal interference.

In FIG. 5, the transceivers in the transceiver array 131A in the data exchange module 130 are taken as an example. Because the transceivers in the transceiver array 113 and the transceivers in the transceiver array 131A meet the physical location as shown in FIG. 5 The arrangement of the transceivers in the transceiver array 113 can be the same as that of the transceivers in the transceiver array 131A; the same position identification can also be used to characterize the transceivers in the transceiver array 113.

In the foregoing description, it has been mentioned that the data exchange device 130 in the cabinet 100 can be based on the physical location of the transceiver array 113 of the server 110 and the transceiver array 131A of the data exchange device 130 by establishing the transceiver array 131A and the transceiver array 113. And assign the same frequency bands, so that the transceiver array 131A and the transceiver array 113 in the transceiver array group 140 can work in the same frequency range to ensure that normal data interaction can be carried out, and specifically for the transceiver array 131A and For the transceivers in the transceiver array 113, the data exchange device 130 can cooperate with the server 110 to manage the transceiver array 131A and the transceivers in the transceiver array 113. The data exchange device 130 can manage each transceiver in the transceiver array group 140. The transceivers of the transceiver group allocate transmission parameters and establish the association relationship of the transceivers in each transceiver group. The data exchange device 130 may also collect the position identifiers of the transceivers in the transceiver array 131A and the transceiver array 113, and adjust the transmission parameters of the transceivers in the transceiver array 131A and the transceiver array 113 in real time.

As a possible implementation, when the data exchange device 130 (such as the processor 132 or the management module 1321 in the data exchange device) detects that the server is inserted in the cabinet, and the server is powered on, the data exchange device 130 can start the data exchange Assuming that the transceiver array 131A in 130 and the transceiver array 113 in the server can also activate the external transceiver 133 in the data exchange device 130.

The data exchange device 130 collects information of the transceiver array 131A and the transceiver array 113, which includes but is not limited to the signal frequency, signal strength, error information, and each transceiver in the transceiver array 131A and the transceiver array 113. Position identification of each transceiver; and configure the transceiver array 131A and the transceiver array 113.

The data exchange device 130 can determine the two transceivers to be associated in the transceiver array 131A and the transceiver array 113 through the physical location of each transceiver in the transceiver array 131A and the transceiver array 113, and use the same for these two transceivers. The configuration, such as signal frequency, signal strength, etc., establishes the relationship between the two transceivers. Exemplarily, the data exchange device 130 can determine the two transceivers to be associated in the transceiver array 131A and the transceiver array 113 through the position identification of each transceiver of the transceiver array 131A and the transceiver array 113, which can be based on the transceiver The position identification of each transceiver in the array 131A and the transceiver array 113 configures the two transceivers to be associated in the transceiver array 131A and the transceiver array 113.

For example, both the transceiver array 131A and the transceiver array 113 can use the method shown in FIG. 5 to identify the position of the transceiver, and the selected horizontal and vertical coordinates and the origin position are coincident, and the data exchange device 130 collects the transceiver array After the position identification of each transceiver of 131A and transceiver array 113, it can be determined that the transceiver with the same mid-position identification of transceiver array 131A and transceiver array 113 is the transceiver to be associated, forming a transceiver group, and Configure the transceiver to be associated.

For another example, the transceiver array 131A and the transceiver array 113 use the method shown in FIG. 5 to identify the position of the transceiver, but the selected horizontal and vertical coordinates and the origin position do not coincide. The data exchange device 130 may be based on the transceiver array 131A and The relative position of the origin in the transceiver array 113, after collecting the position identification of each transceiver of the transceiver array 131A and the transceiver array 113, it can be determined between the transceiver array 131A and the middle position identification of the transceiver array 113 The transceivers in the relative position of the difference origin are the transceivers to be associated, forming a transceiver group, and configuring the transceivers to be associated.

The foregoing method determines the two transceivers to be associated based on the physical location of the two transceivers. The embodiment of the present application does not limit the data exchange device 130 to determine the transceiver array 131A and the transceiver array 113. The location identifier determines the manner of two transceivers to be associated in the transceiver array 131A and the transceiver array 113.

The assignment operation of the data exchange device 130 to the transmission parameters of the two transceivers in a transceiver group in the transceiver array 131A and the transceiver array 113 includes but is not limited to: assigning each transceiver in the transceiver array 131A and the transceiver array 113 The signal frequency, signal strength, receiving sensitivity, bandwidth, wireless beam direction, communication coding mode, etc. of the device.

Among them, the configuration of signal strength and receiving sensitivity can enable the receiving end (transceiver array 131A or one of the transceivers in transceiver array 113) to receive wireless signals of appropriate strength and reduce interference. The signal frequency configuration can avoid interference caused by wireless signals of the same frequency. In the case that the physical positions of the two corresponding transceivers are misaligned, the direction of the wireless signal can be changed by configuring the wireless beam direction to ensure that the two corresponding transceivers can communicate. In practical applications, you can also choose a suitable communication coding mode according to the actual wireless signal conditions to reduce the bit error rate.

Exemplarily, the data exchange device 130 may allocate the same transmission parameters to two transceivers in a transceiver group in the transceiver array group 140, for example, it may allocate the same sub-band (multiple frequencies constitute the sub-band) or frequency , The allocated sub-band or frequency belongs to the frequency band configured by the data exchange module 130 for the transceiver array group 140. Different transceiver groups in the transceiver array group 140 are allocated different transmission parameters, such as different sub-bands or frequencies.

It should be noted that for different transceiver groups, such as the transceiver group 141 and the transceiver group 142, the data exchange device 130 can allocate different sub-bands to different transceiver groups. For example, the data exchange device 130 can be the transceiver group. 141 allocates the sub-band 0-10MHz, and allocates the sub-band 20-30MHz for the transceiver group 142. After that, the data switch device 130 cooperates with the server 110 and the server 120 respectively to configure the sub-band 0-10 MHz for the two transceivers in the transceiver group 141 and configure the frequency band 20-30 MHz for the two transceivers in the transceiver array group 142. In this way, different transceiver groups work in different frequency bands, which can effectively avoid crosstalk of wireless signals interacting in different transceiver groups.

The data exchange device 130 can allocate transmission parameters to the transceivers to be associated in the transceiver array 131A and the transceiver array 113, and after the association relationship is established, the allocated transmission parameters can be transmitted to the server 110; The array 131A configures the transmission parameters, and the server 110 configures the transmission parameters for the transceiver array 113.

After the data exchange device 130 configures the transceiver array 131A and the server to the transceiver array 113, a connection can be established between the transceivers in the transceiver array 131A and the transceivers in the transceiver array 113 to form a one-to-one correspondence. . Optionally, the transceivers in the transceiver array 131A and the transceivers in the transceiver array 113 can determine whether a connection has been established between the corresponding transceivers by sending a detection signal, and data can be exchanged.

The data exchange device 130 can also dynamically adjust the transceivers in the transceiver array 131A and the transceivers in the transceiver array 113; in some possible cases, due to the arrangement of the transceivers in the transceiver array 131A and the transceivers The arrangement of the transceivers in the array 131A may cause one transceiver to correspond to multiple transceivers in physical location. Taking Figure 4 as an example, take the transceiver TX as the top and the height D in the bottom surface of the cone (the bottom surface The diameter is D*Tanθ), there are two transceivers RX, resulting in a transceiver TX in the transceiver array 131A in a physical location opposite to the two transceivers RX; taking Figure 5 as an example, there are two transceivers in the transceiver array 131A The distance B2 of the transceiver RX is less than D*Tanθ, which may cause two transceivers RX in the transceiver array 131A to be associated with one transceiver TX in the transceiver array 113.

The data exchange device 130 can adjust the received signal frequencies of the two transceivers RX to ensure that the frequencies of one transceiver RX and the transceiver TX are consistent, and the frequencies of the other transceiver RX and the transceiver TX are not consistent. In this way, the data exchange device 130 can ensure the association relationship between the transceivers in the transceiver array 131A and the transceivers in the transceiver array 113 through dynamic adjustment.

In the above description, the data exchange device 130 dynamically adjusts the transceivers in the transceiver array 131A and the transceivers in the transceiver array 113 by adjusting the frequency of the transceiver, and the embodiment of the present application is not limited to other methods. Make dynamic adjustments. Optionally, the data exchange device 130 may also adjust the direction angle of the wireless signal by adjusting the beam direction of the wireless signal sent by the transceiver, so that the wireless signal sent by the transceiver can only be received by one associated transceiver.

The above description only refers to the real-time adjustment of the transmission parameters of the associated transceiver by the data exchange module 130. In the specific configuration process, the data exchange device 130 can determine the transmission parameters to be adjusted, and then cooperate with the server 110 to adjust the associated transceiver. The transmission parameters of the device are adjusted.

In a possible implementation manner, when the position of the server in the cabinet 100 is changed, or a new server is inserted in the cabinet 100, the data exchange device 130 can start the position after the server position is changed or when a new server is inserted in the cabinet. The changed service or the transceiver array in the newly inserted server, and start the transceiver array associated with the transceiver array in the data exchange device; collect the information of the associated transceiver, and use the same method as described above for the associated transceiver array. The transceiver is configured to realize the connection of the associated transceiver. This allows users to update the server in the cabinet without having to configure the transmission function of the server. The data exchange device 130 processes it in real time, which can effectively improve the operation and maintenance efficiency of the cabinet and the data center, making the cabinet The management is more convenient.

The data exchange device 130 needs to interact with the server 110 in order to realize the allocation of the frequency bands of the transceiver array 131A and the transceiver array 113 and the configuration of the transmission parameters of each transceiver group. An interaction method is listed below:

The management module 1111 and the management module 1321 can use the transceiver array 113 of the server 110 and the transceiver array 131A in the data exchange device 130 to perform data exchange. Exemplarily, a pair of transceivers with the same position identification in the transceiver array 131A and the transceiver array 113 can be configured in advance, and the same signal frequency can be configured, so that when the server 110 is powered on, and the transceiver in the data exchange device 130 After the transceiver array 131A is started, the two pre-configured transceivers can directly exchange data because the frequency is configured. The management module 1111 and the management module 1321 can exchange data through these two transceivers to transmit the transceiver array of the server 110 113 and the information of the transceiver array 131A in the data exchange device 130, such as location identification, etc.; the management module 1321 may determine the transceiver array 113 of the server 110 and the transceiver array 131A of the data exchange device 130 based on the location identification to be associated with the transceiver The management module 1321 assigns transmission parameters to the transceiver array 113 of the server 110 and the transceiver array 131A of the data exchange device 130 to establish the association relationship between the transceivers, such as the configuration frequency band and the frequency of the associated transceiver. The allocated transmission parameters are sent to the management module 1111 through the pre-configured transceiver. The management module 1111 configures the transmission parameters of the transceiver array 113, such as the transmission parameters of each transceiver in the transceiver array 113; the management module 1321 configures the transceiver array 131A For example, the transmission parameters of each transceiver in the transceiver array 131A. For the transceiver array 131A and other transceivers in the transceiver array 113 that are not pre-configured, after the management module 1111 and the management module 1321 cooperate to configure transmission parameters for these transceivers, they can be subsequently used to transmit service data.

Wherein, configuring the same signal frequency for a pair of transceivers with the same position identification in the transceiver array 131A and the transceiver array 113 in advance also provides a method for the management module 1321 to determine the associated transceiver array 131A and the transceiver array 113; After the server 110 is powered on, and the transceiver array 131A in the data exchange device 130 is started, the management module 1321 can exchange data through a pair of transceivers with pre-configured signal frequencies in the transceiver array 131A and the transceiver array 113. The transceiver array 131A where the two transceivers are located is associated with the transceiver array 113, and they are physically opposite (because the physical locations are not relative, the transceiver array 131A and the transceivers in the transceiver array 113 usually cannot perform data interaction) .

Optionally, in order to reduce the signal interference between the transceiver array 113 in the server 110 and the transceiver array 131A of the data exchange device, a shielding layer may be provided in the space between the transceiver array 113 and the transceiver array 131A; for example, A shielding layer is attached to the portion of the server slot between the opposing transceiver array 131A and the transceiver array 113, and a shielding layer is attached to the portion of the cabinet 110 between the opposing transceiver array 131A and the transceiver array 113. The material of the shielding layer is not limited in the embodiments of this application. For example, the shielding layer may be a metal plate or a metal coating, or other conductive polymer materials or coatings.

As shown in FIG. 6, it is a vertical cross-sectional structure diagram of the cabinet 100. The vertical cross-section of the cabinet 100 is parallel to the front and rear panels of the cabinet. The data exchange device 130 includes a transceiver array 131A and a transceiver array 131B, respectively It is associated with the transceiver array 113 in the server 110 and the transceiver array 123 in the server 120.

The server 110 and the server 120 are inserted into the cabinet through the slot 160 in the cabinet; the space between the transceiver array 131A and the transceiver array 113 can be provided with a shielding layer 161, and the space between the transceiver array 131B and the transceiver array 123 can be Set the shielding layer 161. Exemplarily, the shielding layer 161 may be attached to the slot 160; it should be understood that FIG. 6 only shows that the shielding layer 161 is provided on the upper and lower sides of the space between the transceiver array 113 and the transceiver array 131A. The space between the array 113 and the transceiver array 131A may also be provided with shielding layers 161 on both front and rear sides.

The data exchange device 130 may also include an external transceiver 133. In FIG. 6, the data exchange device includes two external transceivers 133, and each external transceiver 133 can perform data transmission with an external transceiver in another data exchange device.

Similar to the structure of the server 110, the server 120 and the data exchange device 130, another group of servers (server 170, server 180) and a data exchange device 190 are exemplarily drawn in FIG. 6, and the data exchange device 190 includes two transceivers. The transceiver array 191A and the transceiver array 191B are respectively associated with the second transceiver array 133 in the server 170 and the second transceiver array 143 in the server 180; the data exchange device 190 may also include an external transceiver 193.

Based on the system architecture shown in FIG. 1, an embodiment of the present application provides a server communication method. As shown in FIG. 7, the method includes:

Step 701: The data exchange equipment in the cabinet where the first server is located establishes the second transceiver array in the first server based on the positions of the first transceiver array in the data exchange equipment in the cabinet and the second transceiver array in the first server An association relationship with a first transceiver array of the data exchange device, and the second transceiver array and the first transceiver array in the association relationship constitute a first transceiver array group.

The data exchange equipment in the cabinet where the first server is located establishes the second transceiver array and data exchange in the first server by assigning the same frequency band to the second transceiver array and the first transceiver array in the first transceiver array group The association relationship of a first transceiver array of the device.

In addition to frequency bands, the data exchange equipment in the cabinet where the first server is located can also be configured with other transmission parameters, such as signal strength, signal strength, and error information. The embodiment of the present application does not limit the type of the transmission parameter configured by the data exchange device in the cabinet where the first server is located.

Specifically, taking the data exchange equipment in the cabinet where the first server is located as an example, the operation of the data exchange equipment in the cabinet where the second server is located is similar to the operation of the data exchange equipment in the cabinet where the first server is located. The description of the data exchange equipment in the cabinet where the server is located will not be repeated here.

The data exchange equipment in the cabinet where the first server is located determines the position of each transceiver in the second transceiver array and the first transceiver array in the first transceiver array group. The data exchange equipment in the cabinet where the first server is located is based on each transceiver. Establish the association relationship between the transceivers in the second transceiver array and the transceivers in the first transceiver array, and the transceivers in the association relationship form a transceiver group in the first transceiver array group. For any transceiver group in the first transceiver array group, the data exchange equipment in the cabinet where the first server is located allocates the same frequency to the transceivers in the transceiver group to establish the transceivers in the second transceiver array and The association relationship of the transceivers of the first transceiver array.

In addition to frequency, the data exchange device in the cabinet where the first server is located can also be configured with other transmission parameters, such as signal strength, signal strength, and error information.

The data exchange device in the cabinet where the first server is located can determine the first transceiver array by the position identification of each transceiver in the second transceiver array in the first transceiver array group and the first transceiver array in the first data exchange device The position of each transceiver in the second transceiver array in the group and the first transceiver array in the first data exchange device.

If the location identification of each transceiver in the second transceiver array in the first server is set, and the location of each transceiver in the first transceiver array in the first data exchange device corresponding to the second transceiver array in the first server The setting methods of the flags are the same. The same setting method here means that the naming rules of the location flags and the locations indicated by the same location flags are consistent.

The data exchange device in the cabinet where the first server is located can be allocated to the transceivers with the same position identifier in the second transceiver array in the first server in the first transceiver array group and the first transceiver array in the first data exchange device The same frequency.

Step 702: The first server sends a first message to the data exchange device through the second transceiver array in the first server, and the destination address carried in the first message is the address of the second server.

Based on the related descriptions in Figures 1 to 6, it can be seen that the second transceiver array in the first server in the first transceiver array group and the first transceiver array in the first data exchange device can communicate directly. Since the physical locations of the first transceiver array and the second transceiver array in the first transceiver array group meet the requirements shown in FIG. 2 and the configured frequency bands are the same, the second transceiver array in the first server sends the second transceiver array. A message can only be received by the first transceiver array in the first transceiver array group.

Step 703: After receiving the first message, the data exchange device forwards the first message to the third transceiver array in the second server according to the target address carried in the first message.
