Detailed Description
The core of the application is to provide a VPD data operation method, which can be applied to a Chassis Management Controller (CMC) of a computer. A computer may be configured with a main memory and a spare memory, which may be one or more. Each memory corresponds to a separate channel, and the chassis management controller can access the memories through the respective channels of the memories. Each memory stores computer VPD data. The VPD data may include a plurality of logical data blocks, each logical data block corresponding to a check value.
The main memory and the spare memory may be an EEPROM (Electrically Erasable and Programmable read only memory).
As shown in fig. 1, which is a schematic diagram of a computer, the chassis management controller 110 may access the main memory 120 and the spare memory 130 through separate channels. The standby memory 130 is taken as an example here.
In the embodiment of the present application, the VPD data may be subjected to data logical partitioning in advance to obtain a plurality of logical data blocks of the VPD data. Each logical data block may be a data consistency Check region and corresponds to a Check value, such as a Cyclic Redundancy Check (CRC) Check value. The corresponding check value for each logical data block may be placed at the end of the logical data block. Each logical data block has its own length, offset, check value in memory.

Referring to fig. 2, a flowchart of an implementation of a VPD data operation method provided in an embodiment of the present application may include the following steps:
s210: a request for an operation on VPD data is received.
In practical applications, when other software or equipment needs to use the VPD data, a corresponding operation request can be sent to the chassis management controller. The operation request may be a read request or a modify request.
After receiving the operation request for VPD data, the chassis management controller may continue to perform the operation of step S220.
S220: and determining a target logical data block where target data to be operated is located.
In an embodiment of the present application, the VPD data stored in the main memory and the spare memory comprises a plurality of logical data blocks. The data contained in different logical data blocks is different.
After receiving an operation request for VPD data, the chassis management controller may determine a target logical data block where target data to be operated is located. Specifically, the determination may be performed according to a data association relationship established in advance.
S230: and reading the target logical data block in the main memory, and carrying out data consistency check on the target logical data block based on a check value corresponding to the target logical data block in the main memory.
The case management controller receives an operation request for VPD data, can read a target logical data block in a main memory after determining the target logical data block where target data to be operated are located, and performs data consistency check on the target logical data block based on a check value corresponding to the target logical data block in the main memory after reading the target logical data block. Specifically, the read check value of the data contained in the target logical data block may be calculated through a unified check algorithm, and the calculated check value is compared with the check value corresponding to the target logical data block in the main memory, where the two check values are consistent, indicating that the check is successful, and if the two check values are inconsistent, indicating that the check is failed.
If the verification is successful, the operation of step S240 may be continuously performed. If the verification fails, the operation of step S250 may be continuously performed.
S240: and performing corresponding operation on the target data in the read target logical data block.
And the case management controller reads the target logical data block in the main memory and performs data consistency check on the read target logical data block, if the check is successful, the target logical data block read in the main memory can be considered as valid data, and corresponding operation can be performed on the target data in the read target logical data block.

S250: and reading the target logic data block in the standby memory, and carrying out data consistency check on the target logic data block based on a check value corresponding to the target logic data block in the standby memory.
And the case management controller reads the target logical data block in the main memory and performs data consistency check on the read target logical data block, and if the check fails, the target logical data block read from the main memory can be considered as invalid data and is unavailable. In this case, the target logical data block may be read in the spare memory, and the data consistency check may be performed on the target logical data block based on the check value corresponding to the target logical data block in the spare memory. The verification process is the same as above and is not described in detail.
If the verification is successful, the target logical data block read in the spare memory may be considered as valid data, and step S240 may be executed to perform corresponding operations on the target data in the read target logical data block. Meanwhile, if the verification is successful, the target logical data block read in the spare memory can be written back to the main memory to replace the target logical data block in the main memory. This may cause the target logical data block in main memory to be updated with valid, usable data. The consistency of the data in the main memory and the spare memory is maintained.
If the verification fails, the target logical data block read in the spare memory may be considered invalid data and unusable. If the spare memory is multiple, the target logic data block can be continuously read in other spare memories, and data consistency check is carried out. The process is the same as above and is not described in detail.

The VPD data are stored redundantly through the main memory and the standby memory, the VPD data reading success rate can be improved, in addition, the VPD data comprise a plurality of logic data blocks, when an operation request to the VPD exists, only the target logic data block where the target data to be operated are located can be read, the reading efficiency is improved, in addition, only the consistency check is needed to be carried out on the target logic data block, the consistency check is not needed to be carried out on all the VPD data, the problem of time consumption caused by the fact that the check is added to the low-speed memory can be effectively solved, the data checking efficiency can be improved, the accuracy of the read data is guaranteed when the VPD data are operated, and the influence on the correct operation of a system is avoided.

If the write back to the main memory and/or the spare memory is successful, a modification success information may be returned. For further operation by the requestor.
If the write back to the main memory and the spare memory fails, data modification failure information is returned. In practical application, it may be caused by a communication problem or a hardware problem that both write-back failures occur when writing back the modified target logical data block and the corresponding check value thereof to the main memory and the spare memory, and in this case, data modification failure information may be returned to facilitate a technician to perform problem troubleshooting in time. Errors may also be reported to the system.
If a write back to main memory or spare memory fails, the target logical data block is marked as stale data in the write back failed memory. If write back failure occurs when the modified target logical data block and the corresponding check value thereof are written back to the main memory and the spare memory, the target logical data block may be marked as invalid data in the write back failure memory. Therefore, when the next operation request needs to read the target logic data block, the data in the memory marked with the failure data is not read, and the corresponding data is directly read from other memories, so that the reading efficiency can be further improved.
