Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a model identification method, device, equipment, medium and circuit for a rack-mounted server. Background Art

[0002] As the Internet, communications, and power industries have different requirements for various server application scenarios, the configuration requirements for rack servers also vary greatly, which has led to the emergence of multiple models of rack servers to meet the needs of various application scenarios. For example, rack servers can include 1U (Unit, height unit), 2U and 4U models. U is the height unit of the server cabinet, which is used to specify the size of the server. The height of a U is 1.75 inches (about 44.45 mm).

[0003] At present, the concept of Board ID (i.e., model code) is used in the design of server motherboards to distinguish different product models, which is used to make logical judgments for BIOS (Basic Input Output System) or BMC (Baseboard Management Controller) to realize different functions or services. Board ID mostly uses 8-bit binary values. In related technologies, managers can only generate new Board IDs by changing the form of hardware electronic BOM (Bill of Material) so that the server's BIOS or BMC can distinguish different server models for corresponding information display and function switching. Each new electronic BOM requires additional BOM maintenance and testing manpower. At the same time, different electronic BOMs produce different motherboards, which is prone to motherboard stagnation. Therefore, how to flexibly configure the model information of rack-mounted servers so that multiple products can share a motherboard to complete product development, reduce production costs and the operating costs of board material management, and reduce the situation of warehousing stale materials is an urgent problem to be solved today. Summary of the invention

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0038] Please refer to Figure 1 ,Figure 1 The flowchart of a method for identifying the model of a rack-mounted server provided by an embodiment of the present invention. The method may include:

[0039] Step 101: Obtain the connection information of the cooling fans of the rack-mounted server; wherein, the connection information of the cooling fans includes the presence or absence of the fan management board and / or the presence or absence of the fans at preset fan positions, and the number of preset fan positions is less than the number of all fan positions of the rack-mounted server.

[0040] Among them, the connection information of the cooling fans in this embodiment may be the information of the cooling fans set in the rack-mounted server, such as the information of the cooling fans connected to the main board in the rack-mounted server. For the specific content of the connection information of the cooling fans in this embodiment, the designer can set it according to the practical scenario and user requirements. For example, the connection information of the cooling fans may include the presence or absence of the fan management board (i.e., the presence or absence of the fan management board), so as to distinguish different models by whether there is a fan management board in the rack-mounted server; the connection information of the cooling fans may also include the presence or absence of the cooling fans at some of the fan positions (i.e., preset fan positions) among all the fan positions of the rack-mounted server (i.e., the presence or absence of the fans), so as to distinguish different models by the differences in the settings (such as the number or position) of the cooling fans in the rack-mounted server, that is, the presence or absence of the fans at the preset fan positions. This embodiment does not make any restrictions on this.

[0041] Correspondingly, the presence or absence of the fans at the above-mentioned preset fan positions may be the presence or absence of the cooling fans at each preset fan position respectively, that is, the model identification device can directly receive the presence or absence of the cooling fans at each preset fan position (such as a level signal). The presence or absence of the fans at the preset fan positions may also be a preset number of signals (such as level signals) corresponding to the presence or absence of the cooling fans at all the preset fan positions, and the preset number may be less than the number of preset fan positions, so as to distinguish the presence or absence of the cooling fans at all the preset fan positions in different models through the preset number of signals, and reduce the number of ports required by the model identification device.

[0042] It should be noted that for the specific method of obtaining the connection information of the cooling fans of the rack-mounted server in this step, the designer can set it according to the usage scenario and user requirements. For example, the model identification device can receive the presence status of the cooling fans at each preset fan position. For example, the model identification device can use ports with the number of preset fan positions to connect to the presence status input terminals of the cooling fans at each preset fan position respectively. When the presence status input terminal of the cooling fan at a certain preset fan position outputs a high level (such as 3.3V), it is determined that the cooling fan at this preset fan position is in the present state. When the presence status input terminal of the cooling fan at this preset fan position outputs a low level (such as 0V), it is determined that the cooling fan at this preset fan position is not in the present state. The model identification device can also receive the presence status of the fans at the preset fan positions sent by the logic gate circuit, that is, the model identification device can use a preset number of ports to connect to the corresponding output terminals of the logic gate circuit to receive a preset number of signals corresponding to the presence status of the cooling fans at all preset fan positions. For example, when the preset number is 1, the model identification device can determine the presence status of the cooling fans at all preset fan positions according to the 1-channel level signal output by the logic gate circuit. For example, when the logic gate circuit outputs a high level, it can indicate that the cooling fans at all preset fan positions are in the present state. When the logic gate circuit outputs a low level, it can indicate that the cooling fans at all preset fan positions are not all in the present state.

[0043] For example, the requirements for the number of externally plugged cooling fans and whether to use a fan board are the same for air-cooled and liquid-cooled rack-mounted servers. Due to the differences in the chassis structures of 1U, 2U, and 4U models, the specifications for placing the cooling fans and the requirements for whether to use a fan management board are also different, which can avoid misplugging and misjudgment to a certain extent. As shown in Table 1 below, the 1U model rack-mounted server needs to be equipped with 8 cooling fans (FAN) of the 4056 specification to meet the cooling requirements. The 2U model rack-mounted server is equipped with 6 cooling fans of the 6056 specification to meet the cooling requirements. For the 4U model rack-mounted server, due to the large structural differences, a fan management board (FAN Board) is needed to support the management of the fans. That is to say, there are differences in the use (such as the number) of cooling fans among 1U, 2U, and 4U models.

[0044] Table 1 Display table of the cooling fan configurations of the rack-mounted servers of each model

[0045]

[0046] Correspondingly, FAN6, FAN7, FAN8, and FAN9 can be fan interfaces specifically used for 1U models. The 2U model does not use these four fan interfaces FAN6 to FAN9. The 4U model uses a fan management board and is only connected to the main control of the motherboard through one interface for logic, and will not be mixed and inserted with 1U and 2U models. In some embodiments, the heat dissipation fan connection information may include the presence status of the fan management board and the presence status of the fans at the preset fan positions. All the fan positions of the rack-mounted server may include 10 fan positions corresponding to Fan 0 (FAN0) - Fan 9 (FAN9), and the preset fan positions may include 4 fan positions corresponding to Fan 6 (FAN6) - Fan 9, so as to distinguish the 4U model from other models (i.e., 1U model and 2U model) through the presence status of the fan management board, and distinguish the 1U model from the 2U model through the presence status of the fans at these four preset fan positions (i.e., fan interfaces) FAN6 to FAN9.

[0047] As Figure 2 shown, the logic gate circuit may include a first AND gate device (Q1), a second AND gate device (Q2), and a third AND gate device (Q3); the two input terminals of the first AND gate device and the two input terminals of the second AND gate device are respectively connected one-to-one to the presence status input terminals (FAN6_PRSNT_N - FAN9_PRSNT_N) of the 4 preset fan positions, and the two input terminals of the third AND gate device are respectively connected one-to-one to the input terminals of the first AND gate device and the second AND gate device; the output terminal of the third AND gate device may be connected to one input terminal (IO_1_1) of the model identification device (U64). When high levels (i.e., presence status) are input to all the presence status input terminals of the 4 preset fan positions, the third AND gate device may output a high level to the model identification device, indicating that the presence status of the fans at the preset fan positions is all in the presence state.

[0048] Step 102: Determine the model information of the rack-mounted server according to the fan connection information.

[0049] Among them, the model information of the rack-mounted server in this embodiment can be information for expressing the model of the rack-mounted server (such as models of 1U, 2U, or 4U, etc.). The specific content of the model information can be set by the designer according to the usage scenario and user requirements. For example, the model information can include the Board ID (model code) of the server motherboard, such as the 8-bit model code conventionally set in the related art. For example, the BMC or CPU (firmware code control) of the server can respectively read the high and low levels of the GPIO (General-purpose input / output) of the PCA9555 (a kind of gate circuit device, that is, the model identification device) through the I2C (Inter-Integrated Circuit, integrated circuit bus) bus to identify the 8-bit binary Board ID.

[0050] Correspondingly, the determined model information of the rack-mounted server in this embodiment is any preset model information. For example, all the fan positions of the rack-mounted server include 10 fan positions corresponding to fans 0 - fan 9 (such as FAN0 - FAN9 in Figure 1 ), and when the preset fan positions include 4 fan positions corresponding to fans 6 - fan 9, the preset model information can include 1U (height unit) model information, 2U model information, and 4U model information to achieve the identification and differentiation of 1U, 2U, and 4U models.

[0051] For the specific method of determining the model information of the rack-mounted server by the model identification device according to the fan connection information in this step, it can be set by the designer according to the practical scenario and user requirements. For example, when the heat dissipation fan connection information includes the presence / absence status of the fan management board, the model identification device can, based on the presence / absence status of the fan management board, achieve the identification of 1U and 4U models or 2U and 4U models and determine the corresponding model information. When the heat dissipation fan connection information includes the presence / absence status of the fan management board and the presence / absence status of the fans at the preset fan positions, if the model information includes an 8-bit model code (Board ID), then the model identification device (such as the PCA9555 chip) can, based on the presence / absence status of the fan management board, determine the value of the first bit in the model code; based on the presence / absence status of the fans at the preset fan positions sent by the logic gate circuit, determine the value of the second bit in the model code; based on the received level signals corresponding to the third bit to the eighth bit respectively, determine the values of the third bit to the eighth bit in the model code. Among them, the logic gate circuit includes a first AND gate device, a second AND gate device, and a third AND gate device; the two input terminals of the first AND gate device and the two input terminals of the second AND gate device are respectively connected one-to-one to the presence / absence status input terminals of 4 preset fan positions, and the two input terminals of the third AND gate device are respectively connected one-to-one to the input terminals of the first AND gate device and the second AND gate device.

[0052] For example, if Figure 2 As shown in the figure, IO_1_[7:0] of the PCA9555 chip represents the 8-bit Board ID, and IO_1_0 (i.e. the first bit, bit0) is the in-position PIN (pin) of the external fan management board (FAN Board), i.e. the output terminal of the fan management board in-position status. The PIN can be high level by default, and the logic level is 1, indicating that the FAN Borad is not in position; when the FANBoard is in position, the PIN state is low level, and the logic level is 0; that is to say, when the fan management board in-position status is low level in-position status, the value of the first bit is 0; when the fan management board in-position status is high level in-position status, the value of the first bit is 1.

[0053] IO_1_1 (i.e., the second bit, bit1) is connected to an external logic gate circuit. The logic gate circuit outputs a high level to represent a 2U model; the output low level represents a 1U model. In other words, the three AND gate devices (i.e., the first AND gate device to the third AND gate device) in the logic gate circuit can logically AND the presence of the four cooling fans FAN6-9 to produce a total logic level; the presence of the four cooling fans FAN6-9 is high by default, and the logic level is 1, indicating that FAN is not in place; when FAN is in place, the PIN state of the corresponding output end is low, and the logic level is 0; when the total logic level is high, it can indicate that FAN6-9 are not in place (i.e., 2U model), and when the total logic level is low, it can be defaulted to indicate that FAN6-9 are not in place (i.e., 1U model).

[0054] IO_1_[7:0]'s 5bit[7:2] (i.e., bit 3 to bit 8, bit 2-7) can be the default logic level and can be set by the designer, such as Figure 2 As shown, the logic level can be set to 111011, that is, the input terminals corresponding to the 3rd bit, the 4th bit, and the 6th bit to the 8th bit can be connected to the preset high level output terminal through a resistor (such as Figure 2 In P3V3_STBY in the figure, the input terminal corresponding to the 5th bit can be grounded through a resistor; that is, the model code in the 1U model information can be 11101101, the model code in the 2U model information can be 11101111, and the model code in the 4U model information can be 11101110.

[0055] Correspondingly, in other embodiments, the fan management board presence status output terminal can be configured to output a low-level not-in-place state by default, that is, when the fan management board presence status is a high-level in-place state, the value of the first bit is 1; when the fan management board presence status is a low-level not-in-place state, the value of the first bit is 0.

[0056] Step 103: Send the model information to the baseboard management controller and / or the central processing unit of the rack-mounted server.

[0057] It can be understood that in this embodiment, the model identification device of the rack-mounted server can send the model information of the rack-mounted server (such as Board ID) to the BMC or CPU of the rack-mounted server, so that the BMC or CPU can flexibly identify the model and correspondingly implement different functions and services. For example, the model identification device can send the Board ID to the BMC and / or CPU of the rack-mounted server through the I2C bus.

[0058] Furthermore, in this embodiment, the model identification device of the rack-mounted server can also detect whether the determined model information of the rack-mounted server is a certain preset model information. When the model information is the preset model information, the model information is sent to the BMC and / or CPU through Step 103; when the model information is not the preset model information, it is determined that the model information is incorrect and an error can be reported to ensure the safety of subsequent server use. For example, when the preset model information includes the above Board IDs of 11101101 for the 1U model, 11101111 for the 2U model, and 11101110 for the 4U model, if the determined Board ID is other values outside the above three Board IDs, such as 11101100, it can be considered that the determined Board ID is incorrect and an error warning can be sent to the BMC and / or CPU.

[0059] Correspondingly, in some other embodiments, the BMC or CPU that receives the model information can detect whether the received model information of the rack-mounted server is a certain preset model information, and when the model information is not the preset model information, an alarm is sent to the management personnel to remind the management personnel that there is an error in the configuration of the server's cooling fan or the model identification is incorrect.

[0060] In this embodiment, the embodiment of the present invention determines the model information of the rack-mounted server according to the fan connection information, and can flexibly configure the model information of the rack-mounted server based on the difference analysis of the cooling fans of different models, according to the presence or absence of some cooling fans and / or fan management boards in the rack-mounted server, enabling multiple products to share one motherboard to complete product development, reducing the production cost and the operating cost of board material control, reducing the situation of warehouse dead stock, and being able to release the input manpower and time of research and development, achieving the purpose of cost reduction and efficiency improvement.
