BMC pass I2The C bus communicates with the PSU and monitors the operating state of the PSU.
At present, the PSU adopts the same refresh frequency for all information in the running process, and all information is refreshed and then stored in a register. The current communication mode between the BMC and the PSU is to sequentially read the values of all registers of the PSU according to the register definition table given by the PSU.
For the PSU, the amount of information for single refresh is too much, and the time consumption for single refresh in the existing scheme results in low overall refresh frequency, and needs to be improved in the real-time performance of fault state response.

FIG. 1 is a flow chart of the method of the present invention.
Fig. 2 is a system block diagram of the present invention.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings.
A method for refreshing and reading PSU information as shown in fig. 1 includes the following steps:
s1: in the PSU, 30 registers are set that require real-time refreshing of data.
257 registers from 00h to FFh are arranged inside the PSU, wherein the enabled registers which can be inquired by the BMC are close to 100 registers; the asset information of the PSU and the logic judgment parameters in the operation process are stored in a part of registers, and real-time refreshing is not needed; the number of registers that need to be refreshed in real time is 30.
S2: in the registers, a register for displaying the current health state of the PSU is set as a first-class register, a register for predicting the health state of the PSU is set as a second-class register, and other registers are set as third-class registers.
S3: the data in the first type register is set to be updated once every round, the data in the second type register is set to be updated once every two rounds, and the data in the third type register is set to be updated once every four rounds.
The importance of storing data in the registers is not the same for the operational stability of the PSU itself. In order to improve the real-time performance of important data, the current PSU health state data is regarded as important data, the data of the predicted PSU health state is regarded as general data, the rest is unimportant data, and registers are divided into three types according to the importance degree of the data: a first type register, a second type register, and a third type register. For important data, the updating frequency is improved; for less important data, the update frequency is reduced.
According to register data in the PSU, the number ratio of a first-class register, a second-class register and a third-class register is 1: 1: 1, i.e. 10 per data. The important data is updated once every round, the general data is updated once every two rounds, the unimportant data is updated once every four rounds, and the updating frequency of the important data register is improved compared with the original scheme by taking four rounds as a unit.
The time required by the PSU for updating one register is 1ms, and according to the original scheme, the time required for updating four rounds is 30+30+30+ 30-120 ms; according to the new scheme, the time required for four updating wheels is 10+20+10+30 which is 70 ms; the important data are updated four times, the whole time is shortened by 42%, and the updating frequency of the important data is improved by 71.4%. Accordingly, the refresh frequency of general data is reduced by 14.3%, and the refresh frequency of insignificant data is reduced by 57.1%.
S4: among the registers, a register for displaying the entire status data of the PSU is set as a key register, and the other registers are set as non-key registers.
S5: the BMC reads the data of the key register once every turn and reads the data of the non-key register once every ten turns.
For the stability of the whole operation of the server system, the monitoring frequency should be adjusted according to the importance of the data in different registers to the whole operation of the server, and only one piece of information in the PSU data required by the whole server is the most important, namely the whole PSU state data, and other data are general data. Therefore, of the 30 data registers that need to be refreshed in real time, as long as one critical register is used, the others are non-critical registers. Important data is monitored every round, and general data is monitored every ten rounds.
The time required for the BMC to inquire one PSU state word is 1ms, and according to the original scheme, the time required for inquiring 10 rounds is 30 × 10-300 ms; according to the new scheme, the time required for updating 10 rounds is 1 × 9+ 30-39 ms; the important data are updated 10 times, the whole time is shortened by 87%, the refreshing frequency of the important data is improved by 669%, and the refreshing frequency of the general data is reduced by 23%.
Correspondingly, as shown in fig. 2, the present invention also discloses a system for refreshing and reading PSU information, which includes:
the setting unit is used for setting a plurality of registers needing real-time refreshing in the PSU;
the first register classification unit is used for classifying the registers into a first type register, a second type register and a third type register according to a preset standard;
the data updating frequency setting unit is used for setting the data in the first class register to be updated once every round, setting the data in the second class register to be updated once every two rounds, and setting the data in the third class register to be updated once every four rounds;
the second register classification unit is used for setting a register used for displaying the whole state data by the PSU as a key register and setting other registers as non-key registers in the register;
and the data reading frequency setting unit is used for setting that the BMC reads the data of the key register once every turn and reads the data of the non-key register once every ten turns.
Correspondingly, the invention also discloses a device for refreshing and reading PSU information, which comprises:
a memory for storing a computer program;
a processor for implementing the method steps of refreshing and reading PSU information as described in any one of the above when said computer program is executed.
