[0002] For certain business needs, at least two identical hard drive expansion boards need to be connected to the motherboard via high-speed connectors and cables. Each hard drive expansion board needs to be configured with a different slot number.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] Example 1

[0041] Figure 1 This is a flowchart illustrating a method for determining a single-board slot number according to Embodiment 1 of the present invention. This embodiment is applicable to situations involving determining single-board slot numbers. The method can be executed by a device for determining single-board slot numbers, which can be implemented in hardware and / or software. This device can be configured within the entire machine, wherein the screw posts of the entire machine are respectively connected to the screw holes of at least two single boards via connectors. Figure 1 As shown, the method includes:

[0042] S110. For each of the at least two single boards, determine the first screw hole where the connector is fixed from the screw holes on the current single board; wherein the position of the first screw hole is different for each of the screw holes on each single board.

[0043] In this embodiment of the invention, the complete machine is connected to at least two single boards. The screw posts of the complete machine are respectively connected to the screw holes of the at least two single boards via connectors, thereby achieving the connection between the complete machine and the at least two single boards. Each single board has at least one screw hole on its edge, and the complete machine has at least one screw post. The number of screw holes on the edges of each single board and the number of screw posts on the complete machine can be the same or different. This embodiment of the invention does not limit the number of screw holes and screw posts.

[0044] For each of at least two single boards, the first screw hole for fixing the connector is determined from the screw holes on the current single board. It is understood that when the current single board is connected to the complete machine, not every screw hole and screw post on the single board is fixed with a connector when assembled with the screw posts on the complete machine. Therefore, it is necessary to determine the screw hole for fixing the connector from the screw holes on the current single board, and this screw hole is referred to as the first screw hole. It should be noted that the position of the first screw hole on each single board is different. For example, if the complete machine is connected to three single boards, and each single board has three screw holes, and the number of first screw holes for fixing the connector on each single board is two, then the position of the first screw hole on the first single board can be the first and second screw holes; the position of the first screw hole on the second single board can be the first and third screw holes; and the position of the first screw hole on the third single board can be the second and third screw holes. Optionally, the connector can be a screw.

[0045] S120. Determine the high and low level signals of the interfaces on the at least two single boards that are electrically connected to each screw hole in a one-to-one correspondence; wherein, the high and low level signals of the first interface and the second interface are different, the first interface is the interface electrically connected to the first screw hole, the second interface is the interface electrically connected to the second screw hole, and the second screw hole is the screw hole other than the first screw hole among the screw holes on the single board.

[0046] In this embodiment of the invention, each screw hole on each board is electrically connected to an interface, which can be a CPLD or a general purpose input / output (GPIO) interface of another chip. For each board on at least two boards, the high and low level signals of the interfaces electrically connected to each screw hole on the current board are determined. The high and low level signals of the first interface and the second interface are different; for example, the high level signal of the first interface is high, and the high and low level signal of the second interface is low; or, the high and low level signal of the first interface is low, and the high and low level signal of the second interface is high. The first interface is electrically connected to the first screw hole where a connector is fixed, and the second interface is electrically connected to the second screw hole where no connector is fixed. The second screw hole where no connector is fixed can be understood as any screw hole on the board other than the first screw hole.

[0047] S130. For each board, determine the slot number of the current board based on the high and low level signals of each interface on the current board.

[0048] For example, for each board, according to a pre-set interface sequence, the slot number of the current board is determined based on the high and low level signals of each interface on the current board. Since the positions of the first screw holes are different on each board, the high and low level signals of the interfaces electrically connected to the screw holes on each board are different. For example, the entire machine is connected to three single boards, and each single board has three screw holes. Each single board has two first screw holes for fixing connectors. The first screw hole on the first single board is located at the first and second screw holes. Therefore, the high and low level signals of the interfaces electrically connected to each screw hole on the first single board are: low level, low level, high level. Similarly, the first screw hole on the second single board is located at the first and third screw holes. Therefore, the high and low level signals of the interfaces electrically connected to each screw hole on the second single board are: low level, high level, low level. The first screw hole on the third single board can be located at the second and third screw holes. Therefore, the high and low level signals of the interfaces electrically connected to each screw hole on the third single board are: high level, low level, low level. For example, if a low level signal is represented by 0 and a high level signal by 1, then the slot number of the first single board is 001, the slot number of the second single board is 010, and the slot number of the third single board is 100.

[0049] The method for determining the slot number of a single board according to an embodiment of the present invention is applied to a complete machine. The method involves connecting the screw posts of the complete machine to the screw holes of at least two single boards via connectors. The method includes: for each of the at least two single boards, determining a first screw hole from the screw holes on the current single board where the connector is fixed; wherein the position of the first screw hole is different for each single board; determining the high and low level signals of the interfaces on the at least two single boards that are electrically connected to each screw hole; wherein the high and low level signals of the first interface and the second interface are different, the first interface being the interface electrically connected to the first screw hole, and the second interface being the interface electrically connected to the second screw hole, where the second screw hole is a screw hole other than the first screw hole on the single board; and determining the slot number of the current single board based on the high and low level signals of the interfaces on the current single board. The technical solution provided by this embodiment of the invention allows for the configuration of the slot numbers of each single board without occupying connector pins, making connector selection more flexible when connecting the single boards to the complete machine.

[0050] Example 2

[0051] Figure 2This is a flowchart illustrating a method for determining a single-board slot number according to Embodiment 1 of the present invention. This embodiment is applicable to situations involving determining a single-board slot number. This method can be executed by a device for determining the single-board slot number, which can be implemented in hardware and / or software and can be configured within the single-board. Figure 2 As shown, the method includes:

[0052] S210. When the screw posts of the whole machine are connected to the screw holes on the single board through the connector, the position information of the connector on the single board is determined.

[0053] The single board has at least one screw hole on its frame and at least one screw post on the whole machine. The number of screw holes on the frame of the single board and the number of screw posts on the whole machine can be the same or different. This embodiment of the invention does not limit the number of screw holes and screw posts.

[0054] In this embodiment of the invention, when the single board is connected to the complete machine, that is, when the screw posts of the complete machine are connected to the screw holes on the single board via connectors, the position information of the connectors on the single board is determined. It is understood that when the single board is connected to the complete machine, not every screw hole and screw post is fixed with a connector when assembled with the screw posts on the complete machine. Therefore, it is necessary to determine the position information of the connectors on the single board, that is, to determine the position of the screw holes of the connectors on the single board.

[0055] S220. Determine the high and low level signals of at least one interface on the single board according to the location information; wherein, the screw holes on the single board are electrically connected to the at least one interface in a one-to-one correspondence.

[0056] The board has at least one interface, which can be a general purpose input / output (GPIO) interface of a CPLD or other chip. The GPIO can be pulled high by a resistor. Each screw hole on the board is electrically connected to at least one interface. It is understood that the number of screw holes on the board is the same as the number of interfaces.

[0057] In this embodiment of the invention, the high and low level signals of each interface on the single board that is electrically connected to a screw hole are determined based on the position information of the connector on the single board. That is, the high and low level signals of each interface electrically connected to a screw hole on the single board are determined based on the position of the screw hole where the connector is located. For example, the high and low level signals of the interface corresponding to the screw hole at the location of the connector on the single board are different from the high and low level signals of the interfaces corresponding to other screw holes. These other screw holes are all screw holes on the single board except for the screw hole at the location of the connector.

[0058] Optionally, determining the high / low level signal of at least one interface on the single board based on the location information includes: determining a first screw hole on the single board from among the screw holes on the single board where the connector is fixed, based on the location information; determining that the high / low level signal of the interface electrically connected to the first screw hole is low, and the high level signal of the interface electrically connected to the second screw hole is high; wherein, the second screw hole is a screw hole on the single board other than the first screw hole. For example, based on the screw hole position of the connector on the single board, the screw hole on which the connector is fixed is determined from all the screw holes on the single board, and the screw hole on which the connector is fixed is designated as the first screw hole. It can be understood that the screw hole corresponding to the screw hole position of the connector on the single board is designated as the first screw hole. The high / low level signal of the interface on the single board electrically connected to the first screw hole is set to low (which can be represented by 0), and the high level signal of the interface electrically connected to the second screw hole is set to high (which can be represented by 1); wherein, the second screw hole is a screw hole on the single board other than the first screw hole.

[0059] Optionally, the single board is provided with N screw holes, and the single board slot of the whole machine is provided with M screw posts; wherein, when the single board is connected to the whole machine, M third screw holes among the N screw holes are assembled with the M screw posts; M≤N; according to the position information, the first screw hole for fixing the connector is determined from the screw holes on the single board, including: when P target screw holes among the M third screw holes are respectively connected to P target screw posts among the M screw posts one by one through the connector, the P target screw holes are determined as the first screw holes for fixing the connector.

[0060] In this embodiment of the invention, GPIO is used as an example for explanation. The board frame has N screw holes, each corresponding to a GPIO on the board. Therefore, the board also has N GPIOs. The initial level of each GPIO on the board can be pulled high by a resistor. Optionally, 2 N The number of boards that can be installed on the entire machine is greater than or equal to the maximum number of boards that can be installed on the entire machine. Based on business requirements, multiple identical boards need to be connected to the entire machine. Therefore, the maximum number of boards that can be connected to the entire machine can be determined based on the pre-set configuration information. Based on the maximum number of boards that can be installed on the entire machine, the number N of screw holes to be set on the edge of the board is determined, where 2 NThe maximum number of boards that can be installed in the entire machine is greater than or equal to the maximum number of boards that can be installed. For example, if the maximum number of boards that can be installed in the entire machine is 3, then N can be 2 or 3. If the maximum number of boards that can be installed in the entire machine is m, then the entire machine has m board slots. Each board slot in the entire machine has M screw posts, where M ≤ N, and the positions of the M screw posts in each board slot are different. When a board is connected to the entire machine, the M third screw holes out of the N screw holes can be assembled with the M screw posts; where the third screw holes are the screw holes corresponding to the positions of the M screw posts.

[0061] In this embodiment of the invention, when the single board is connected to the complete machine, the M third screw holes on the single board are assembled one-to-one with the M screw posts on the frame of the complete machine. If P target screw holes among the M first screw holes are connected one-to-one with the P target screw posts among the M screw posts through screws, the P target screw holes can be connected to the P target screw posts one-to-one through the screws, thereby making the GPIO electrically connected to the P target screw holes shorted to GND, so that the high and low level signals of the GPIO electrically connected to the P target screw holes on the single board are low (can be represented by 0), while the high and low level signals of the GPIO electrically connected to the other NP screw holes (i.e., the third target screw holes) on the single board are high (can be represented by 1). Among them, the third target screw holes include two types of screw holes: one type is screw holes that are assembled with the screw posts on the frame of the complete machine but without screws, and the other type is screw holes that are not assembled with the screw posts on the frame of the complete machine.

[0062] S230. Determine the slot number of the single board based on the high and low level signals of the at least one interface.

[0063] In this embodiment of the invention, the slot number of a single board is determined according to a pre-set interface order and based on the high and low level signals of each interface on the board. Optionally, determining the slot number of the single board based on the high and low level signals of at least one interface includes: obtaining a pre-set interface order; wherein the interface order is the order used to generate the single board slot number; and determining the slot number of the single board based on the high and low level signals of at least one interface according to the interface order. For example, the user can adjust the pre-set interface order as needed, wherein different pre-set interface orders result in different slot numbers of the single board generated based on the high and low level signals of at least one interface. There can be one or more single boards. When there are multiple single boards, each single board can determine its own slot number according to the single board slot number determination scheme provided in S210-S230.

[0064] For example, when a maximum of 3 identical boards can be installed on a single machine, N can be any integer greater than or equal to 2. Two schemes are described below:

[0065] Option 1 Figure 3a This is a schematic diagram of the design structure of a single-board frame and a complete machine frame provided in an embodiment of the present invention. Figure 3b This is a schematic diagram illustrating the configuration of the single-board slot number after the single-board is connected to the entire machine, as provided in an embodiment of the present invention. Figure 3a As shown, N=2 and M=2, meaning that the edge of the single board has two screw holes that are electrically connected to the GPIOs one-to-one, and the entire chassis has two screw posts that correspond to the screw holes on the single board. Figure 3b As shown, when the single board is connected to the complete machine, the two screw posts on the machine frame and the two screw holes on the single board frame are assembled together. Users can screw screws onto the screw posts as needed. The GPIO output level signal connected to the screw hole with the screw is low (0), and the GPIO output level signal connected to the screw hole without the screw is high (1). Therefore, the single board slot number can be any one of four: 00, 01, 10, and 11. This scheme can use N screw holes to configure 2 N With a slot number, when the number of boards is large, this solution can configure slot numbers for boards with fewer screw holes and GPIOs.

[0066] Option 2 Figure 4a This is a schematic diagram of another design structure for the single-board frame and the overall machine frame provided in an embodiment of the present invention. Figure 4b This is a schematic diagram illustrating the configuration of the single-board slot number after the single-board is connected to the entire machine, as provided in an embodiment of the present invention. Figure 4a As shown, N=3 and M=1, meaning that the board's edge has three screw holes that are electrically connected to each GPIO, and the chassis has one screw post that corresponds to the screw holes on the board. Figure 4b As shown, when the single board is connected to the complete machine, the three screw posts on the machine frame are assembled with one screw hole on the single board frame. The user can screw screws onto the screw posts as needed. The output level signal of the GPIO electrically connected to the screw hole with the screw is low (0), and the output level signal of the GPIO electrically connected to the screw hole without the screw is high (1). When the entire frame and the single board are connected to the grounding screw hole of the single board via the screw posts and screws, and the single board is installed in the slot and screwed in, the slot number changes from 111, 111, 111 to 011, 101, 110. This solution requires only one screw per single board, necessitating more GPIOs and screw holes, but effectively avoids incorrect screw insertion during machine assembly.

[0067] For example, when a maximum of four identical boards can be installed on a single machine, N≥2, and so on. This method is very flexible, allowing for the selection of the number of screw holes pre-drilled on the board frame based on product requirements and future plans. When the board needs to be reused on other machines, only the machine frame needs to be adapted.

[0068] The method for determining the slot number of a single board according to embodiments of the present invention is applied to a single board. The method includes: when the screw posts of the whole machine are connected to the screw holes on the single board through a connector, determining the position information of the connector on the single board; determining the high and low level signals of at least one interface on the single board according to the position information; wherein the screw holes on the single board are electrically connected to the at least one interface in a one-to-one correspondence; and determining the slot number of the single board based on the high and low level signals of the at least one interface. Through the technical solution provided by the embodiments of the present invention, the configuration of the single board slot number can be completed without occupying connector pins, making connector selection more flexible when connecting the single board to the whole machine.

[0069] In some embodiments, after determining the slot number of the single board, the method further includes: obtaining a pre-defined mapping relationship between slot numbers and single board slots; and determining the target single board slot in the entire machine based on the slot number of the single board and the mapping relationship. Specifically, obtaining the mapping relationship between slot numbers and single board slots, wherein the slot number and single board slot have a one-to-one correspondence. Based on the determined slot number of the single board and the mapping relationship between slot numbers and single board slots, the target single board slot in the entire machine is determined.

[0070] In some embodiments, after determining the slot number of the single board, the method further includes: sending the slot number to the complete machine, wherein the slot number is used to instruct the complete machine to perform service configuration on the single board. Specifically, the single board sends its determined slot number to the complete machine, enabling the complete machine to perform service configuration on the complete machine based on the slot number of the single board. Different slot numbers indicate different positions of the single board within the complete machine, resulting in different service management configurations for the single board.
