[0044] Based on the above purpose, a first aspect of an embodiment of the present invention provides an embodiment of a BBU power supply method.

[0049] The BBU power supply method of the embodiment of the present invention controls the DIP switch module to select a backup power mode through a CPLD logic control module, and selects BBU modules of corresponding quantity and power from the BBU modules according to the selected backup power mode to power the storage server, thereby realizing backup power supply for a large number of storage servers through a small number of BBU modules, greatly saving hardware cost expenditure and reducing the occupied space of the storage server. In addition, compared with the storage server backup power supply method in the prior art, it is more flexible and more reliable.

[0050] In some embodiments, the method also includes: reading the level signals of multiple dip switches in the dip switch module by the GPIO pin of the CPLD logic control module, and confirming the corresponding backup power mode based on the level signals; wherein the level signal of each dip switch is a high level signal or a low level signal, multiple dip switches correspond to multiple groups of level signals, and each backup power mode corresponds to a group of level signals.

[0051] In some embodiments, according to the selected backup power mode, BBU modules of corresponding quantity and power are selected from the BBU modules, and the storage server is powered by the selected BBU modules, including: in response to the selected backup power mode being a single-channel power supply mode, a BBU module with maximum power is selected from the BBU modules, and the storage server is powered by the BBU module with maximum power; in response to the selected backup power mode being a multi-channel power supply mode, multiple BBU modules with large power are selected from the BBU modules, and the storage server is powered by multiple BBU modules with large power.

[0056] Figure 2 Schematic diagram of the system structure of the BBU power supply method provided in the embodiment of the present invention. Figure 2 As shown, the specific implementation of the BBU power supply method of the present invention is as follows:

[0057] (1) A BMC (Baseboard Management Controller) baseboard management module is used to exchange information with the storage server through 1000M network communication. When the storage server has an abnormal power supply phenomenon of the PSU (Power Supply Unit), the storage server transmits the signal to the BMC baseboard management module through the 1000M network. After the BMC baseboard management module parses the network communication, it interacts with the CPLD (Complex Programming Logic Device) through the IIC (Inter-Integrated Circuit) 1 bus for data communication, so that the CPLD logic control module drives the discharge enable of the BBU (Battery Backup Unit) module through the GPIO (General-purpose input / output) bus 3 channel, thereby realizing the function of backing up the storage server.

[0058] (2) Diversity of backup power modes: the backup power system has multi-channel switching branches ( Figure 2 The 16-channel switching branch is shown in the figure), which can meet various BBU backup power forms; it can realize the backup power of one BBU module for the storage server, and it can also realize multiple BBU modules ( Figure 2 The backup power supply form of the storage server is shown in Table 1 below:

[0059] Table 1

[0060]

[0061] Among them, backup power paths 1 to 4 use a single-channel power supply mode. When a storage server has a power supply abnormality, the backup power device system will select the BBU module with the largest power among BBU1 to BBU4 for backup power operation;

[0062] Backup power paths 5 to 10 use a dual-channel power supply mode. When a storage server has a power supply anomaly, the backup power device system will select the two BBU modules with the largest power among BBU1 to BBU4 for backup power operation.

[0063] Backup power paths 11 to 14 use a three-channel power supply method. When a storage server has a power supply anomaly, the backup power device system will select the three BBU modules with the largest power among BBU1 to BBU4 for backup power operation.

[0064] The backup power path 15 adopts a four-channel power supply method. When a storage server has a power supply abnormality, the backup power device system will select BBU1 to BBU4 to directly perform the backup power operation.

[0065] (3) Use the CPLD logic control module to read the DIP switches A, B, and C through the general GPIO pins to determine which backup power mode is used, as shown in Table 2 below:

[0066] Table 2

[0067] A B C Backup mode 0 0 1 Backup mode 1 0 1 0 Backup mode 2 0 1 1 Backup mode 3 0 0 0 Backup mode 4 1 0 0 Backup mode 5 1 1 1 Backup power mode 6

[0068] Backup power mode 1 is a single-channel power supply mode, which selects the maximum power for backup power, including backup power paths 1 to 4;

[0069] Backup power mode 2 is a dual-channel power supply mode, which selects the two with the largest power for backup power, including backup power paths 5 to 10;

[0070] Backup power mode 3 is a three-channel power supply mode, which selects three maximum power levels for backup power, including backup power paths 11 to 14;

[0071] Backup power mode 4 is a full-channel power supply mode, which selects all power for backup power, including backup power path 15;

[0072] Backup power mode 5 uses the auto-negotiation backup power mode. It does not select according to the value of the DIP switch, but negotiates with the logic set by the storage server itself to select a backup power mode of 1 to 4.

[0073] Backup power mode 6, that is, not using the backup power function, is generally used for R&D and debugging.

[0074] (4) As few BBU backup power modules as possible are used, and 16 backup power outputs are realized through the control of the GPIO bus 3 of the CPLD logic control module, thereby meeting the backup power capacity of at least 16 controllers. Compared with the previous storage server equipment, at least 12 BBU backup power modules are saved, which greatly saves the cost of operation. At the same time, compared with the previous storage server backup power mode, multiple backup power modes are more reliable and more variable, as shown in Table 3:

[0075] Table 3

[0076] GPIO bus 3 control pin Storage Server Supply Branch Storage Servers Provided GPIO_BBU_En1 12V Channel 1 Storage Server Controller 1 GPIO_BBU_En2 12V Channel 2 Storage Server Controller 2 GPIO_BBU_En3 12V Channel 3 Storage Server Controller 3 GPIO_BBU_En4 12V Channel 4 Storage Server Controller 4 GPIO_BBU_En5 12V Channel 5 Storage Server Controller 5 GPIO_BBU_En6 12V Channel 6 Storage Server Controller 6 GPIO_BBU_En7 12V Channel 7 Storage Server Controller 7 GPIO_BBU_En8 12V Channel 8 Storage Server Controller 8 GPIO_BBU_En9 12V Channel 9 Storage Server Controller 9 GPIO_BBU_En10 12V channel 10 Storage Server Controller 10 GPIO_BBU_En11 12V channel 11 Storage Server Controller 11 GPIO_BBU_En12 12V Channel 12 Storage Server Controller 12 GPIO_BBU_En13 12V channel 13 Storage Server Controller 13 GPIO_BBU_En14 12V channel 14 Storage Server Controller 14 GPIO_BBU_En15 12V channel 15 Storage Server Controller 15 GPIO_BBU_En16 12V channel 16 Storage Server Controller 16

[0077] (5) The BMC baseboard management module collects the battery capacity of BBU1 to BBU4 through the IIC2 bus, and communicates with the CPLD logic control module through IIC1 to further confirm which BBU module has low power. The CPLD logic control module then controls the charging control channel to confirm which BBU module to charge, and uses a separate PSU module (not the PSU in the storage server) to charge the BBU module. At the same time, the CPLD logic control module will collect the abnormal signal of the PSU module. When the power supply of the PSU module is abnormal, the CPLD logic control module will transmit this signal to the BMC baseboard management module through IIC communication, and then transmit it to the large system through 1000M network communication, thereby realizing the monitoring of PSU power supply abnormality and BBU power by this backup power device system.

[0078] (6) The BMC baseboard controller intermittently collects the battery capacity of each BBU module in the backup power system through the IIC bus. When the capacity of one BBU is lower than the critical value (i.e. the preset threshold), it notifies the CPLD logic control module to charge the BBU. The charged BBU module will not be added to the backup power mode until it is fully charged. When any of the BBU modules fails to charge or discharge, the CPLD logic control module will automatically disconnect all the enabled functions of the BBU module, making the BBU module idle. At the same time, the BMC will transmit the 1000M network signal to all storage servers, and then inform the operation and maintenance personnel to replace it, thereby increasing the reliability and maintenance capabilities of the backup power.

[0079] (7) The BMC baseboard management module is used to communicate through the IIC2 bus to collect the temperature of the BBU1~BBU4 modules. At the same time, the fan speed is controlled according to the collected results to ensure the temperature stability of the backup power system during operation. The PWM1 signal generated by the BMC baseboard management module is transparently transmitted through the CPLD logic control module, and the PWM2 signal is output, thereby controlling the fan cooling module to control the fan speed. The TACH2 signal of the fan cooling module is transparently transmitted through the CPLD logic control module and then output as the TACH1 signal to feed back to the BMC baseboard management module, thereby realizing the feedback closed-loop management of the fan speed, and at the same time realizing the CPLD logic control module to monitor the normal operation of the BMC baseboard management module.

[0080] A second aspect of the embodiments of the present invention further provides a BBU power supply system.
