Server management systems, methods, equipment, computer program products and media
[0001] Cross-reference of related applications
[0002] This application claims priority to Chinese Patent Application No. 202411958209.9, filed on December 27, 2024, entitled "Server Management System, Method, Apparatus, Computer Program Product and Media", the entire contents of which are incorporated herein by reference. Technical Field
[0003] This application relates to the field of server technology, and in particular to a server management system, method, device, computer program product, and non-volatile readable storage medium. Background Technology
[0004] The mainstream storage device is the eMMC (Embedded Multi Media Card) storage device. eMMC storage devices have an 8-bit data width. When using a VGA (Video Graphics Array) interface, it is impossible to read and write data using the 8-bit data width of eMMC. Typically, when using a VGA interface, only the 4-bit data width of the eMMC storage device can be used for data reading and writing, resulting in a data read / write speed that is half that of using the 8-bit data width.
[0005] To ensure high data read / write speeds, current solutions either use only the DisplayPort (DP) interface or replace eMMC storage devices with UFS (Universal Flash Storage) devices. However, using only the DP interface without a VGA interface can cause inconvenience for server maintenance, requiring additional DP video signal transmission cables, DP-to-VGA adapters, or even replacing the monitor, thus increasing maintenance costs. Replacing eMMC storage devices with UFS storage devices increases server costs. Therefore, finding a way to support VGA interfaces while maximizing data read / write speeds without increasing server costs has become a pressing technical problem for those skilled in the art.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0035] Please refer to Figure 1, which is a schematic diagram of a server management system provided in an embodiment of this application. As shown in Figure 1, the system includes:
[0036] The system includes a management controller 10, a data selection device 20, and a multimedia storage device 30. The management controller 10 includes a multimedia storage interface. The target pin in the multimedia storage interface is connected to the data selection device 20, and the data selection device 20 is also connected to the multimedia storage device 30 and the target video transmission interface.
[0037] The management controller 10 is used to configure the function of the target function multiplexing pin in the multimedia storage interface, so that the function of the target function multiplexing pin is adapted to the object that establishes a connection with the target function multiplexing pin;
[0038] Data selection device 20 is used to establish a connection between the target function multiplexing pin and the target video transmission interface; or, to establish a connection between the target pin and the multimedia storage device 30; the target pin includes the target function multiplexing pin.
[0039] Some embodiments of the server management system mainly include a management controller 10, a data selection device 20, and a multimedia storage device 30. The management controller 10 includes, but is not limited to, devices with server management and control functions such as a BMC (Baseboard Management Controller) and an ILO (Integrated Lights-Out) remote controller. The data selection device 20 is a multiplexer. The multimedia storage device 30 can be an eMMC storage device. Adapted to the eMMC storage device, the multimedia storage interface in the management controller 10 is an eMMC interface. The target pins in the multimedia storage interface are connected to the data selection device 20, and the data selection device 20 is also connected to the multimedia storage device 30 and the target video transmission interface. The target video transmission interface refers to a video transmission interface that does not support data reading and writing of the full data bit width of the multimedia storage device 30. The target video transmission interface can be a VGA interface. The target pins include at least the target function multiplexing pins and the data pins not used by the multimedia storage interface when using the target video transmission interface. The target function multiplexing pins include the DATA6 / VGA I2C SCL pin and the DATA6 / VGA I2C SDA pin in the multimedia storage interface. The DATA6 / VGA I2C SCL pin can be used as a data pin or as the SCL (Serial Clock) pin in the VGA interface I2C (Inter-Integrated Circuit) bus. The DATA6 / VGA I2C SDA pin can be used as a data pin or as the SDA (Serial Data) pin in the VGA interface I2C bus. When using the target video transmission interface, the data pins used by the multimedia storage interface can be directly connected to the multimedia storage device 30 or connected to the data selection device 20 to establish a connection with the multimedia storage device 30 through the data selection device 20.
[0040] In some embodiments, a first target pin in the multimedia storage interface is connected to the multimedia storage device 30, a second target pin in the multimedia storage interface is connected to the output pin of the data selection device 20, and an input pin of the data selection device 20 is connected to the multimedia storage device 30 and the target video transmission interface; the first target pin is the data pin used by the multimedia storage interface when using the target video transmission interface, and the second target pin includes data pins and target function multiplexing pins that are not used by the multimedia storage interface when using the target video transmission interface.
[0041] In some embodiments, some data pins of the multimedia storage interface are directly connected to the multimedia storage device 30, while some data pins, DATA6 / VGA I2C SCL pin, and DATA7 / VGA I2C SDA pin are connected to the data selection device 20.
[0042] Referring to Figure 2, in some embodiments, four data pins in the multimedia storage interface are connected to the multimedia storage device 30, two data pins in the multimedia storage interface are connected to the output pins in the data selection device 20, two function multiplexing pins in the multimedia storage interface are connected to the output pins in the data selection device 20, four input pins in the data selection device 20 are connected to the multimedia storage device 30, and two input pins in the data selection device 20 are connected to the target video transmission interface.
[0043] As shown in Figure 2, when the target video transmission interface is a VGA interface, the four pins DATA0 to DATA4 of the multimedia storage interface in the management controller 10 are respectively connected to the DATA0 to DATA4 pins of the multimedia storage device 30. The DATA5 to DATA7 pins of the multimedia storage interface in the management controller 10 are connected to the output pins 1A to 4A of the data selection device 20. The input pins 1B1 to 4B1 of the data selection device 20 are respectively connected to the DATA4 to DATA7 pins of the multimedia storage device 30. Input pins 3B2 and 4B2 of the data selection device 20 are connected to the VGA video transmission interface. The output pin corresponding to input pins 1B1 and 1B2 is 1A, the output pin corresponding to input pins 2B1 and 2B2 is 2A, the output pin corresponding to input pins 3B1 and 3B2 is 3A, and the output pin corresponding to input pins 4B1 and 4B2 is 4A. The data selection device 20 can connect input pin 1B1 to output pin 1A, or input pin 1B2 to output pin 1A. Similarly, the data selection device 20 can connect input pin 4B1 to output pin 4A, or input pin 4B2 to output pin 4A.
[0044] Additionally, in some embodiments, two input pins in the data selection device 20 are left floating. Referring to FIG2, input pins 1B2 and 2B2 in the data selection device 20 are left floating.
[0045] If the target video transmission interface is used, the management controller 10 configures the DATA6 / VGA I2C SCL pin as the SCL pin in the VGA interface I2C bus, and configures the DATA7 / VGA I2C SDA pin as the SDA pin in the VGA interface I2C bus. If the target video transmission interface is not used, the management controller 10 configures the DATA6 / VGA I2C SCL pin and the DATA7 / VGA I2CSCL pin as data pins. If the target video transmission interface is used, the data selection device 20 establishes a connection between the target function multiplexed pin and the target video transmission interface. As shown in Figure 2, if the target video transmission interface is used, the data selection device 20 connects the output pin 3A to the input pin 3B2 and the output pin 4A to the input pin 4B2, thereby establishing a connection between the target function multiplexed pin and the target video transmission interface. If the target video transmission interface is not used, the data selection device 20 establishes a connection between the second target pin and the multimedia storage device 30. As shown in Figure 2, if the target video transmission interface is not used, then 1A and 1B1 are connected, 2A and 2B1 are connected, 3A and 3B1 are connected, and 4A and 4B1 are connected, thereby establishing a connection between the second target pin and the multimedia storage device 30. In this way, when the VGA interface is not used, the eight data pins of the EMMC storage device are connected to the eight pins of the EMMC storage interface in the management controller 10, enabling data read and write operations on the EMMC storage device with an 8-bit data width, ensuring high data read and write speeds. When the VGA interface is used, the four data pins of the EMMC storage device are connected to the four pins of the EMMC storage interface in the management controller 10, and the two function multiplexing interfaces in the EMMC storage interface are connected to the VGA interface, meeting the requirements for using the target video transmission interface.
[0046] When the management controller 10 does not use the VGA interface, it can use the DP interface. Referring to Figure 3, when performing server maintenance in the server room, if the display devices in the server room support the DP interface, then the DP interface should be used. If the display devices in the server room do not support the DP interface and only support the VGA interface, then the VGA interface should be used.
[0047] In some embodiments, the management controller 10 is configured to: configure the function of the target function multiplexing pin according to the level signal of the judgment pin of the management controller 10; if the level signal of the judgment pin is a first level signal, configure the first function multiplexing pin as a serial clock pin and configure the second function multiplexing pin as a serial data pin; if the level signal of the judgment pin is a second level signal, configure the first function multiplexing pin as a data pin and configure the second function multiplexing pin as a data pin.
[0048] In some embodiments, the management controller 10 is configured based on the level signal of a judgment pin. A first level signal indicates that the target video transmission interface is used. A second level signal indicates that the target video transmission interface is not used. Therefore, if the level signal of the judgment pin is the first level signal, the management controller 10 configures the first multiplexed pin as a serial clock pin and the second multiplexed pin as a serial data pin. If the level signal of the judgment pin is the second level signal, the management controller 10 configures the first multiplexed pin as a data pin and the second multiplexed pin as a data pin.
[0049] The first level signal can be a high level signal, and the second level signal can be a low level signal.
[0050] In some embodiments, the level signal is provided by a switching circuit; when the target video transmission interface is used, the switching circuit outputs a first level signal; when the target video transmission interface is not used, the switching circuit outputs a second level signal.
[0051] The decision pin of the management controller 10 is connected to a switching circuit. The switching circuit outputs different level signals depending on whether the target video transmission interface is used or not. When the target video transmission interface is used, the switching circuit outputs a first level signal. When the target video transmission interface is not used, the switching circuit outputs a second level signal. By applying different level signals to the decision pin of the management controller 10 through the switching circuit, it is possible to implement the application of level signals to the decision pin of the management controller 10 in a low-cost and convenient manner.
[0052] In some embodiments, the data selection device 20 is configured to: establish a connection between the target function multiplexing pin and the target video transmission interface when the level signal of the selection pin of the data selection device 20 is a first level signal; and establish a connection between the target pin and the multimedia storage device 30 when the level signal of the selection pin is a second level signal.
[0053] The selection pin's level signal is set to the first level signal, indicating that the target video transmission interface is used. The selection pin's level signal is set to the second level signal, indicating that the target video transmission interface is not used. When the selection pin's level signal is the first level signal, the data selection device 20 establishes a connection between the target function multiplexing pin and the target video transmission interface; when the selection pin's level signal is the second level signal, the data selection device 20 establishes a connection between the target pin and the multimedia storage device 30.
[0054] In some embodiments, the level signal is provided by a switching circuit; when the target video transmission interface is used, the switching circuit outputs a first level signal; when the target video transmission interface is not used, the switching circuit outputs a second level signal.
[0055] In this embodiment, the selection pin of the data selection device 20 is connected to a switching circuit. The switching circuit outputs different level signals depending on whether the target video transmission interface is used or not. When the target video transmission interface is used, the switching circuit outputs a first level signal. When the target video transmission interface is not used, the switching circuit outputs a second level signal. By applying different level signals to the selection pin of the data selection device 20 through the switching circuit, it is possible to apply level signals to the selection pin of the data selection device 20 in a low-cost and convenient manner.
[0056] In some embodiments, the switching circuit includes a DIP switch; when the DIP switch is set to a first position, the DIP switch outputs a first level signal, and when the DIP switch is set to a second position, the DIP switch outputs a second level signal.
[0057] In some embodiments, the switching circuit that provides a level signal to the decision pin of the management controller 10 and the switching circuit that provides a level signal to the selection pin of the data selection device 20 are the same switching circuit.
[0058] For example, as shown in Figure 4, DIP switches can be configured on the server panel. The DIP switches can be set to different states depending on whether a VGA interface is used. When the DIP switch is flipped up, the output is high, corresponding to using the VGA interface. When the DIP switch is flipped down, the output is low, corresponding to not using the VGA interface. In the server field, the VGA interface is generally not used during normal server operation; therefore, the DIP switch can be flipped down to set it to a low level during normal server operation.
[0059] The cable transmits the level signal to the BMC's decision pin (shown in Figure 2) and the selection pin (shown in Figure 2) of the data selection device 20 (the MUX (Multiplexer) shown in Figure 2). The BMC can determine the level signal of the decision pin through its firmware. When the decision pin is connected to a high-level signal, the BMC uses the VGA interface, and its EMMC interface's DATA6 / VGA I2C SCL pin is configured as VGA I2C SCL, and its EMMC interface's DATA7 / VGA I2C SDA pin is configured as VGA I2C SDA. When the decision pin is connected to a low-level signal, the BMC does not use the VGA interface, and its EMMC interface's DATA6 / VGA I2C SCL pin is configured as EMMC DATA6, and its EMMC interface's DATA7 / VGA I2C SDA pin is configured as EMMC DATA7. The MUX's function is to select the output from the input. As shown in Table 1, when the Select pin is connected to a low-level signal, A = B1, meaning pin 1A is connected to 1B1, pin 2A to 2B1, pin 3A to 3B1, and pin 4A to 4B1. This allows for 8-bit data reading and writing of the EMMC. When the Select pin is connected to a high-level signal, A = B2, meaning pin 1A is connected to 1B2, pin 2A to 2B2, pin 3A to 3B2, and pin 4A to 4B2. This allows for 4-bit data reading and writing of the EMMC. The DATA4 and DATA5 pins of the EMMC interface are left floating. The DATA6 / VGA I2C SCL pin of the EMMC interface is configured as VGA I2C SCL, and the DATA7 / VGA I2C SDA pin of the EMMC interface is configured as VGA I2CSDA. The VGA I2C SCL and VGA I2C SCL are connected to the server's VGA interface.
[0060] Table 1
[0061] In some embodiments, the selection pin of the data selection device 20 is connected to the management controller 10; when the target video transmission interface is used, the management controller 10 outputs a first level signal to the selection pin of the data selection device 20; when the target video transmission interface is not used, the management controller 10 outputs a second level signal to the selection pin of the data selection device 20. That is, the level signal of the selection pin of the data selection device 20 can be applied by the management controller 10, and the data selection device 20 may not be connected to a switching circuit.
[0062] In summary, the server management system provided in this application connects the target pins of the multimedia storage interface in the management controller to a data selection device. The target pins include target function multiplexing pins, and the data selection device also connects the multimedia storage device to the target video transmission interface. When the target video transmission interface is used, the data selection device can establish a connection between the target function multiplexing pins and the target video transmission interface. The management controller configures the function of the target function multiplexing pins to adapt to the target video transmission interface, allowing the target video transmission interface to function normally. When the target video transmission interface is not used, the target pins are connected to the multimedia storage device. The management controller configures the function of the target function multiplexing pins to adapt to the multimedia storage device, enabling all pins of the multimedia storage interface in the management controller to be used as data pins connected to the multimedia storage device. This allows for data read / write operations across the full data bit width of the multimedia storage device, maximizing data read / write speeds. By managing the controller and data selection device, it is possible to switch between using the target video transmission interface and not using the target video transmission interface. This not only meets the requirements of using the target video transmission interface, but also maximizes the data read and write speed, and eliminates the need for UFS storage devices, thus avoiding the increase in server costs and the inconvenience of updating and iterating UFS storage devices.
