The master management unit 110 and the slave management unit 210 need to monitor sensor data of the devices to which they belong, such as temperature and voltage, and perform corresponding processing after an abnormality occurs, for example, adjust the rotation speed of the cooling fan 300 or the number of the cooling fans 300, or turn off the power supply 400 to perform power-off processing of the master device or the slave device.
As shown in fig. 1, the method comprises the steps of:

In this embodiment, the incumbent slave devices are slave devices inserted into the chassis, the master management unit reads the power-on states of the incumbent slave devices, the power-on states may include power-on and power-off, and the target slave devices that have been powered on may be determined according to the power-on states.
Optionally, a state table of each slave device may be preset by the master management unit, and after the on-site slave device is powered on, the master management unit may update the powered-on state of the corresponding slave device in the state table, so that the master management unit may determine the powered-on state of the on-site slave device by reading the state table.
In order to ensure that the on-site slave devices are powered on reliably, in some embodiments of the present application, after the master management unit reads a power-on state of each on-site slave device, and determines a powered-on target slave device according to the power-on state, the method further includes:
if the master management unit monitors a power-on request IPMI message sent by an in-place slave management unit corresponding to the in-place slave equipment, verifying the power-on request IPMI message, and returning an IPMI message agreeing to power on to the in-place slave management unit after the verification is passed so that the in-place slave management unit powers on a CPU of the in-place slave equipment;
the IPMI message is generated by the in-place slave management unit after detecting that the power-on environment of the in-place slave equipment meets the preset condition.
In this embodiment, on one hand, before powering on, the in-place slave management unit of the in-place slave device detects whether a power-on environment of the in-place slave device meets a preset condition, where the preset condition may include that a temperature of the in-place slave device is within a preset temperature range, a power voltage of the in-place slave device is within a preset voltage range, and no protection condition that power-on is not allowed exists, and if the preset condition is met, the in-place slave management unit may generate a power-on request IPMI message and send the power-on request IPMI message to the master management unit of the master device. On the other hand, when receiving the power-on request IPMI message, the master management unit checks, for example, whether the format of the message is correct, whether the in-place slave device to be powered on belongs to a legal device, and the like, and returns the IPMI message agreeing to power on to the in-place slave management unit after the check is passed, and the in-place slave management unit can power on the CPU of the in-place slave device.

In this embodiment, the first IPMI request message may be generated by the master management unit according to a query instruction of a user, and when the user needs to know the operating environment data of the target slave device, the first IPMI request message may be sent to the master management unit, so that the master management unit generates the first IPMI request message; the first IPMI request message may also be generated by the master management unit periodically and automatically, and the master management unit may monitor the operating environment data of the target slave device at any time by periodically sending the first IPMI request message to the target slave management unit.
Step S103, the master management unit determines the operating environment data of the target slave device according to the first IPMI response message returned by the target slave management unit.
In this embodiment, after receiving the first IPMI request message, the target slave management unit verifies the first IPMI request message, and after the verification is passed, the target slave management unit encapsulates the operating environment data of the target slave device to generate a first IPMI response message, where the operating environment data may include sensor data such as temperature and voltage, and then the target slave management unit sends the first IPMI response message to the master management unit, and the master management unit analyzes the first IPMI response message to determine the operating environment data of the target slave device.
Step S104, if abnormal data exists in the operating environment data of the target slave device, the master management unit controls the target slave device according to the abnormal data.
The master management unit judges whether abnormal data exist in the operating environment data of the target slave device, the abnormal data can include temperature abnormal data exceeding a preset voltage range or voltage abnormal data exceeding the preset voltage range, and if the abnormal data exist, the master management unit can control the target slave device according to the abnormal data.
For example, if the abnormal data is temperature abnormal data, the master management unit may adjust the rotation speed or the operation number of the cooling fan of the target slave device; or when the temperature abnormal data is the temperature higher than the protection fixed value, the main management unit can directly perform power-off processing on the target slave device so as to ensure the safety of the target slave device. If the abnormal data is voltage abnormal data, the master management unit can perform power-off processing on the target slave device.
Optionally, when the master management unit controls the target slave device according to the abnormal data, the master management unit stores the abnormal data in a log, so that a user can view specific abnormal data through the log.

On the other hand, the main management unit circularly monitors whether the alarm IPMI message sent from each slave management unit exists, if the alarm IPMI message sent by the target slave management unit is monitored, the main management unit analyzes the alarm IPMI message and controls the target slave equipment according to the analysis result.
For example, if a temperature alarm exists in the analysis result, the master management unit may adjust the rotation speed or the running number of the cooling fans of the target slave device, or perform power-off processing on the target slave device; if the voltage alarm exists in the analysis result, the main management unit can perform power-off processing on the target slave equipment so as to ensure the safety of the target slave equipment.
Optionally, when the master management unit controls the target slave device according to the analysis result, the master management unit stores the analysis result in a log, so that a user can view specific alarm information through the log.
In order to ensure the reliability of the master device, in some embodiments of the present application, before the master management unit reads a power-on state of each in-place slave device and determines a target slave device that has been powered on according to the power-on state, the method further includes:

In order to ensure the reliability of the master device, in some embodiments of the present application, after the master management unit performs a chassis initialization operation according to chassis information, the method further includes:
the main management unit circularly obtains the operating environment data of the main equipment and controls the main equipment according to the operating environment data of the main equipment.
In this embodiment, the operating environment data of the main device may include sensor information such as temperature and voltage of the main device, and if the temperature of the main device exceeds a preset temperature range, a cooling fan of the main device is adjusted or the main device is powered off; if the voltage of the main equipment exceeds the preset voltage range, the main equipment can be powered off.
In order to improve the reliability of the device, in some embodiments of the present application, after the main management unit performs the chassis initialization operation according to the chassis information, the method further includes:
and the main management unit compares the highest temperature values of all the electrified slave devices in the case, adjusts the rotating speed of the cooling fan according to the threshold range where the highest temperature value is located, and performs power-off processing on the electrified slave devices if the temperature of the electrified slave devices exceeds the highest threshold.
In order to perform complete IPMI management in the CPU of the main device, in some embodiments of the present application, the main management unit and the CPU of the main device communicate with each other through a preset serial communication private protocol, in the preset serial communication private protocol, both the request packet and the response packet include a packet header, a message length, an I2c address, a command type, a specific command, specific data, and a check bit, and a completion code is further included between the specific data and the check bit of the response packet.
In this embodiment, the CPU of the master device and the main management unit communicate with each other through a preset serial communication private protocol, as shown in fig. 3, a frame format of the serial communication private protocol in the embodiment of the present invention, where both the Request message Request and the Response message Response include a header head, a message length, an I2c address I2caddr, a command type cmdtype, a specific command cmd, specific data, and a check bit crc16, and a completion code completion is further included between specific data and the check bit of the Response message.
Specifically, the header of the packet is 0xc0 of 3 bytes; the message length is 1 byte; the I2c address I2caddr is the I2c address of the other slave devices that the master device wants to acquire; the command type cmd type is extended from the IPMI standard and may include the types shown in FIG. 4; the specific command cmd uses characters to command numerical values according to an IPMI standard, so that the main management unit can receive messages and directly package the messages into an IPMI frame format conveniently; the specific data is fixed 8 bytes in a Request message Request and fixed 100 bytes in a Response message Response; the check bit crc16 is 2 bytes and is used for checking the accuracy of the message; the completion code completion is 1 byte and the definition of the completion code conforms to the IPMI standard, that is, the main management unit extracts the completion code from the IPMI message sent from the management unit and fills the completion code field, and the definition of the completion code is consistent with the IPMI standard.
In addition, the specific data mainly encapsulates messages of set types in the Request message Request, for example, the cooling fan rotating speed, powerlevel and the like are set, only the first byte of the data is filled with data, the rest part of the data is filled with 0, and for other equipment requests similar to restarting and powering off, the data field is filled with 0 completely.
The encapsulation of the proprietary protocol in the Response message Response about specific data follows two points:
1. the command (for example, a slave device DeviceID command) for acquiring data can be acquired only by once interaction in the IPMI standard, and specific data is packaged according to the IPMI standard;
2. the command that data can be acquired only by multiple interactions in the IPMI standard is required, for example, when the data information of the device sensor is acquired in the IPMI standard, the data is encapsulated based on a private definition. Wherein the private definition includes: for specific data (such as data of a sensor such as temperature and the like) recorded by an IPMI standard without floating point numbers, the package of the specific data occupies three bytes, the first byte represents the type of the sensor and is defined according to the IPMI standard, the second byte represents the mark number of the sensor, and the third byte is a specific sensor numerical value; for specific data (such as class voltage and the like) needing floating point recording, the packaging of the specific data occupies four bytes for transmission, the integer part and the decimal part of the sensor numerical value respectively occupy one byte, the data is packaged according to the sequence of the sensor label, and the vacant part is filled with 0.
In order to ensure the reliability of IPMI management after the main device is abnormal, in some embodiments of the present application, the enclosure further includes a standby main device, where the standby main device continuously performs information interaction with the main device during the operation of the main device, and if the number of times that the main device does not respond reaches a preset number of times, it is determined that the main device is abnormal, and the standby main device is reinitialized as a new main device.
In this embodiment, the standby main device also includes a main device unit, and in the operation process of the main device, the standby main device continuously performs information interaction with the main device, and if the number of times that the main device does not respond reaches a preset number of times, it is determined that the main device is abnormal, and at this time, the standby main device is reinitialized as a new main device, so that the reliability of IPMI management is improved.
By applying the technical scheme, in a case comprising a main device and a plurality of slave devices, the main device is connected with each slave device through an IPMB, a main management unit based on an MCU is arranged in the main device, a slave management unit based on the MCU is arranged in each slave device, the main management unit reads the power-on state of each in-place slave device, and determines the powered-on target slave device according to the power-on state; the method comprises the steps that a master management unit sends a first IPMI request message to a target slave management unit corresponding to a target slave device; the master management unit determines the operating environment data of the target slave equipment according to the first IPMI response message returned by the target slave management unit; if abnormal data exist in the operating environment data of the target slave equipment, the main management unit controls the target slave equipment according to the abnormal data; the first IPMI response message is generated by packaging the running environment data of the target slave equipment after the target slave management unit receives the first IPMI request message, and the cost is reduced by adopting the MCU as the master management unit and the slave management unit compared with a BMC chip.
