Description
Technical Field
The present invention relates to the field of computer technologies, and in particular, to a method and an apparatus for implementing an automatic threshold configuration function of an IPMI power sensor.
Background
The BMC (Baseboard Management Controller, management chip on the server) generally provides a sensor for monitoring Power Supply Unit (PSU) Power consumption or total Power consumption. Such sensors can be used to observe real-time power consumption, but also to issue event alerts or trigger power limitation strategies when power consumption exceeds rated power.
In addition to the recording of the Sensor setting Data, the design method includes Data such as the type of the Sensor, whether a trigger event is present, and a trigger event condition, etc., that is, a research and development engineer writes a trigger condition (threshold) of a Sensor corresponding to a system into an SDR file (or a hardcode into a program) when developing a design product. This conventional implementation may have the following disadvantages when used in a power consumption type sensor:
a. static threshold settings may not be suitable for some product line configurations, and development costs are high. For example:
the A server product line originally is configured with a plurality of display cards with large power consumption, so a PSU with high rated power of 2200 watts is configured. The development engineer also configures the sensor threshold for the power consumption when developing the a product, and the configuration may be that the BMC issues an alarm and executes a power limitation policy when the power consumption reaches 2200 watts. If a new product B wants to continue all the designs of the server A but remove the high-power-consumption display card and replace the high-power-consumption display card with a low-power-consumption display card, the product B does not need to use the high-watt PSU and only needs to use the low-cost low-rated-output 1100-watt PSU. The problem arises here that the original sensor threshold setting is obviously not applicable to the new configuration of the product B, and the engineer must modify the power consumption sensor threshold for the product B again — that is, even if the board is shared, the BMC firmware needs to be modified to meet the new configuration. Vice versa, if the B product adds more graphics cards with larger power consumption, the PSU with higher power rating is also needed. If the BMC firmware does not modify the power consumption sensor threshold, an alarm may be triggered and a power consumption limit executed when the power consumption reaches 2200 watts.
b. Some PSUs output different power ratings depending on the input power. For example, if the PSU is plugged into a 220V power supply, the maximum rated output of the PSU would be 2200 watts. While with the PSU plugged into a 110V supply, the maximum rated output of the PSU would be 1100 watts. This type of PSU may burn out beyond the rated power if a static threshold configuration is used.
PSUs are typically dynamically swappable. If the maintenance personnel misuse the PSUs with different rated power consumption without paying attention, the problem of burning out or failure of the threshold value of the PSU can be caused.

In view of the above objects, a first aspect of the embodiments of the present invention provides an embodiment of a method for implementing an IPMI power sensor automatic threshold configuration function. Fig. 1 is a schematic block diagram illustrating an embodiment of a method of implementing an IPMI power sensor automatic threshold configuration function in accordance with the present invention. In the embodiment shown in fig. 1, the method comprises at least the following steps:
s100, detecting the in-place state of the power supply device through BMC;
s200, responding to the situation that the in-place state is changed from out-of-place to in-place, and triggering a request of an SDR dynamic configuration threshold;
s300, responding to a request of receiving an SDR dynamic configuration threshold, and reading a numerical value of a temporary storage of a power supply device from a PMBUS corresponding to a power sensor;
s400, configuring a threshold value of the SDR according to the numerical value;
and S500, starting a threshold value, and triggering the alarm of the power sensor according to the threshold value.
In some embodiments of the present invention, fig. 2 is a flowchart illustrating an embodiment of a method for implementing an IPMI power sensor automatic threshold configuration function according to the present invention, as shown in fig. 2, detecting an in-place state of a power device by a BMC according to step S100. According to step S200, when the BMC detects that the in-place state of the power device is changed from off-place to in-place, the SDR dynamic configuration code is triggered. According to step S300, the dynamic configuration code first reads the MFR _ POUT _ MAX register value of the Power device from the PMBus (Power Management Bus) corresponding to the sensor, using Power System Management Protocol as the communication Protocol between the Power device and the Management component. According to step S400, the dynamic configuration code checks the MFR _ POUT _ MAX register read back value and dynamically configures the threshold according to the read back value. According to the step S500, the new threshold value of the dynamic new configuration is enabled to be used as an alarm basis.
According to some embodiments of the method of implementing IPMI power sensor automatic threshold configuration functionality of the present invention, configuring the threshold of the SDR according to a value further comprises:

And responding to the judgment that the numerical value is a valid numerical value, calculating a first threshold value according to the numerical value read by the temporary storage, and configuring the first threshold value as the threshold value of the SDR.
And responding to the judgment value as an invalid value, and using a second threshold value of the original static preset SDR as the threshold value of the SDR.
In some embodiments, the register value is checked for validity, and if the read value is a Valid (Valid) value, the appropriate SDR configuration parameter is recalculated.
If the value is an Invalid (Invalid) value, the dynamic configuration code should not reset the SDR configuration with the Invalid value, but instead use the SDR configuration that was originally statically set.
Wherein, the expression of the threshold calculation is as follows:
t: the power consumption sensor threshold that will eventually be used,
P reading : MFR POUT MAX register read back value,
T static : the threshold value is set statically and the threshold value is set,
TC tab : the MFR _ POUT _ MAX register read back value is converted to the corresponding multiplier for the new threshold.
According to some embodiments of the method for implementing the IPMI power sensor automatic threshold configuration function of the present invention, calculating the first threshold according to the value read by the temporary memory further includes:
and calculating a non-critical upper threshold, a critical upper threshold and an unrecoverable upper threshold according to the numerical values.
Configuring a non-critical Upper-limit (Upper non-critical threshold) threshold value to be 1 times of a numerical value;
configuring an Upper critical threshold (Upper critical threshold) value to be 1.05 times the value;
an Upper non-recoverable threshold (Upper non-recoverable threshold) threshold is configured to be 1.1 times the value.
The threshold may be calculated in a number of ways, and in some embodiments of the invention, only a simple multiplier design is used:
upper non-critical threshold: register read back value 1.0 for MFR _ POUT _ MAX;
upper critical threshold: register read back value MFR _ POUT _ MAX 1.05;
upper non-repeatable threshold: register read back value 1.1 for MFR _ POUT _ MAX.
