Technical Field

[0001] The present invention relates to the field of server technology, and in particular to a server management system, method, device, computer program product and medium. Background Art

[0002] The mainstream storage device is the EMMC (Embedded Multi Media Card) storage device. The data bit width of the EMMC storage device is 8 bits. When using the VGA (Video Graphics Array) interface, the 8-bit data bit width of the EMMC cannot be read and written. Usually, when using the VGA interface, only the 4-bit data bit width of the EMMC storage device can be used for data reading and writing, and the data reading and writing rate is half of that when using the 8-bit data bit width for data reading and writing.

[0003] In order to ensure the data read and write rate, currently only the DP (DisplayPort) interface is used, or the EMMC storage device is replaced with a UFS (Universal Flash Storage) storage device. However, using only the DP interface without the VGA interface will bring inconvenience to the server operation and maintenance, and it is necessary to add a video signal transmission line for the DP interface, as well as an adapter cable from the DP interface to the VGA interface or replace the display device, which increases the operation and maintenance cost. Replacing the EMMC storage device with a UFS storage device will increase the server cost. Therefore, how to support the use of the VGA interface, maximize the data read and write rate, and not increase the server cost has become a technical problem that needs to be solved urgently by those skilled in the art.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Please refer to Figure 1 , Figure 1 A schematic diagram of a server management system provided by an embodiment of the present invention, referring to Figure 1 As shown, the system includes:

[0034] Management controller 10, data selection device 20, multimedia storage device 30; 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;

[0035] 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 connected to the target function multiplexing pin;

[0036] The 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.

[0037] The server management system provided in this embodiment mainly includes 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 BMC (Baseboard Management Controller), remote controller ILO (full name Integrated Lights-Out in English). The data selection device 20 is a multiplexer. The multimedia storage device 30 can be an EMMC storage device. Adapting to the EMMC storage device, the multimedia storage interface in the management controller 10 is an EMMC 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. The target video transmission interface refers to a video transmission interface that does not support the full data bit width of the multimedia storage device 30 for data reading and writing. The target video transmission interface can be a VGA interface. The target pin includes at least the target function multiplexing pin and the data pin not used by the multimedia storage interface when the target video transmission interface is used. 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 I2CSCL pin can be used as a data pin, or as an 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 an SDA (Serial Serial Data) pin in the VGA interface I2C bus. When using the target video transmission interface, the data pin used by the multimedia storage interface can be directly connected to the multimedia storage device 30, or it can be connected to the data selection device 20 to establish a connection with the multimedia storage device 30 through the data selection device 20.

[0038] In some embodiments, the first target pin in the multimedia storage interface is connected to the multimedia storage device 30, the second target pin in the multimedia storage interface is connected to the output pin of the data selection device 20, and the 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 a data pin used by the multimedia storage interface when the target video transmission interface is used, and the second target pin includes a data pin and a target function multiplexing pin that are not used by the multimedia storage interface when the target video transmission interface is used.

[0039] In this embodiment, some data pins of the multimedia storage interface are directly connected to the multimedia storage device 30 , and some data pins, the DATA6 / VGA I2C SCL pin and the DATA7 / VGA I2C SDA pin are connected to the data selection device 20 .

[0040] refer to Figure 2 As shown, 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.

[0041] like Figure 2 As shown, when the target video transmission interface is a VGA interface, the four pins DATA0 to DATA4 in the multimedia storage interface in the management controller 10 correspond to the DATA0 to DATA4 pins of the multimedia storage device 30. The DATA5 to DATA7 pins in 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 in the data selection device 20 correspond to the DATA4 to DATA7 pins of the multimedia storage device 30. The input pins 3B2 and 4B2 in the data selection device 20 are connected to the VGA video transmission interface. The output pins 1A corresponding to the input pins 1B1 and 1B2, the output pins 2A corresponding to the input pins 2B1 and 2B2, the output pins 3A corresponding to the input pins 3B1 and 3B2, and the output pins 4A corresponding to the input pins 4B1 and 4B2. The data selection device 20 can connect the input pin 1B1 to the output pin 1A, or connect the input pin 1B2 to the output pin 1A. Similarly, the data selection device 20 can connect the input pin 4B1 to the output pin 4A, or connect the input pin 4B2 to the output pin 4A.

[0042] In addition, in some embodiments, two input pins in the data selection device 20 are left floating. Figure 2 As shown, input pins 1B2 and 2B2 in the data selection device 20 are left floating.

[0043] 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. Configure 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 I2C SCL pin as data pins. If the target video transmission interface is used, the data selection device 20 establishes a connection between the target function multiplexing pin and the target video transmission interface. Figure 2 As shown, if the target video transmission interface is used, the data selection device 20 connects the output pin 3A with the input pin 3B2, and connects the output pin 4A with the input pin 4B2, so as to establish a connection between the target function multiplexing pin and the target video transmission interface. If the target video transmission interface is not used, the data selection device 20 connects the second target pin with the multimedia storage device 30. Figure 2 As shown, if the target video transmission interface is not used, 1A is connected to 1B1, 2A is connected to 2B1, 3A is connected to 3B1, and 4A is connected to 4B1, so as to realize the connection between the second target pin and the multimedia storage device 30. In this way, when the VGA interface is not used, the 8 data pins of the EMMC storage device are connected to the 8 pins of the EMMC storage interface in the management controller 10, and then the 8-bit data width of the EMMC storage device can be realized to read and write data, and the data read and write rate is guaranteed. When the VGA interface is used, the 4 data pins of the EMMC storage device are connected to the 4 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 to meet the demand of using the target video transmission interface.

[0044] When the management controller 10 does not use the VGA interface, the DP interface can be used. Figure 3 As shown in the figure, when performing server maintenance in the server room, if the display device in the room supports the DP interface, use the DP interface. If the display device in the room does not support the DP interface and only supports the VGA interface, use the VGA interface.

[0045] In some embodiments, the management controller 10 is used 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.

[0046] In this embodiment, the management controller 10 is configured according to the level signal of the judgment pin of the management controller 10. The level signal of the judgment pin is a first level signal, indicating that the target video transmission interface is used. The level signal of the judgment pin is a second level signal, indicating that the target video transmission interface is not used. Therefore, if the level signal of the judgment pin is a first level signal, the management controller 10 configures the first function multiplexing pin as a serial clock pin and the second function multiplexing pin as a serial data pin. If the level signal of the judgment pin is a second level signal, the management controller 10 configures the first function multiplexing pin as a data pin and the second function multiplexing pin as a data pin.

[0047] The first level signal may be a high level signal, and the second level signal may be a low level signal.

[0048] In some embodiments, the level signal is provided by a switch circuit; when the target video transmission interface is used, the switch circuit outputs a first level signal; when the target video transmission interface is not used, the switch circuit outputs a second level signal.

[0049] The judgment pin of the management controller 10 is connected to the switch circuit. When the target video transmission interface is used and not used, the level signal output by the switch circuit is different. When the target video transmission interface is used, the switch circuit outputs a first level signal. When the target video transmission interface is not used, the switch circuit outputs a second level signal. By applying different level signals to the judgment pin of the management controller 10 through the switch circuit, applying a level signal to the judgment pin of the management controller 10 can be realized at low cost and conveniently.

[0050] In some embodiments, the data selection device 20 is used to: when the level signal of the selection pin of the data selection device 20 is a first level signal, establish a connection between the target function multiplexing pin and the target video transmission interface; when the level signal of the selection pin is a second level signal, establish a connection between the target pin and the multimedia storage device 30.

[0051] The level signal of the selection pin is a first level signal, indicating that the target video transmission interface is used. The level signal of the selection pin is a second level signal, indicating that the target video transmission interface is not used. When the level signal of the selection pin is a 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 level signal of the selection pin is a second level signal, the data selection device 20 establishes a connection between the target pin and the multimedia storage device 30.

[0052] In some embodiments, the level signal is provided by a switch circuit; when the target video transmission interface is used, the switch circuit outputs a first level signal; when the target video transmission interface is not used, the switch circuit outputs a second level signal.

[0053] In this embodiment, the selection pin of the data selection device 20 is connected to the switch circuit. When the target video transmission interface is used and not used, the level signal output by the switch circuit is different. When the target video transmission interface is used, the switch circuit outputs a first level signal. When the target video transmission interface is not used, the switch circuit outputs a second level signal. By applying different level signals to the selection pin of the data selection device 20 through the switch circuit, it is possible to implement the application of level signals to the selection pin of the data selection device 20 at a low cost and conveniently.

[0054] In some embodiments, the switch circuit includes a dip switch; when the dip switch is turned to a first position, the dip switch outputs a first level signal, and when the dip switch is turned to a second position, the dip switch outputs a second level signal.

[0055] In some embodiments, the switch circuit that provides a level signal to the determination pin of the management controller 10 and the switch circuit that provides a level signal to the selection pin of the data selection device 20 are the same switch circuit.

[0056] For example, Figure 4 As shown, the dip switch can be set on the server panel. The dip switch can be set to different states depending on whether the VGA interface is used. When the dip switch is turned up, the dip switch output is high level, corresponding to the use of the VGA interface. When the dip switch is turned down, the dip switch output is low level, corresponding to not using the VGA interface. In the server field, the VGA interface is generally not used when the server is operating normally. When the server is operating normally, the dip switch can be turned down to set it to a low level.

[0057] The cable transmits the level signal to the BMC judgment pin ( Figure 2 The judgment pin shown in Figure 2 MUX) selection pin ( Figure 2Select pin shown in ). BMC can judge the level signal of the judgment pin through its firmware program. When the judgment pin is connected to a high-level signal, BMC uses the VGA interface, and the DATA6 / VGA I2C SCL pin of its EMMC interface is configured as VGA I2C SCL, and the DATA7 / VGA I2C SDA pin of its EMMC interface is configured as VGA I2C SDA. When the judgment pin is connected to a low-level signal, BMC does not use the VGA interface, and the DATA6 / VGA I2C SCL pin of its EMMC interface is configured as EMMC DATA6, and the DATA7 / VGA I2C SDA pin of its EMMC interface is configured as EMMCDATA7. The function of MUX is to select output for input. As shown in Table 1, when the Select pin is connected to a low-level signal, A=B1, that is, the 1A pin is connected to 1B1, the 2A pin is connected to 2B1, the 3A pin is connected to 3B1, and the 4A pin is connected to 4B1. At this time, the EMMC data with an 8-bit data width can be read and written. When the Select pin is connected to a high level, A=B2, that is, the 1A pin is connected to 1B2, the 2A pin is connected to 2B2, the 3A pin is connected to 3B2, and the 4A pin is connected to 4B2. At this time, the EMMC data with a 4-bit data width can be read and written. The DATA4 pin and DATA5 pin of the EMMC interface are suspended, 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 I2C SDA. VGAI2C SCL and VGA I2C SCL are connected to the VGA interface of the server.

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 the switch circuit.
