[0055] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0056] In the prior art, since the key product data can be updated, for example, one or more types of parameters are added on the basis of the original; the added parameter field increases the length of the read page, and further increases the time of obtaining the key product data, which often causes the time of obtaining the key product data to exceed the specified reading time, so that the node reports an alarm into a service mode and cannot provide services to the outside, thereby affecting the performance of the cluster. To overcome the above technical problems, the present application provides a key product data obtaining method, which can reduce the reading time of the key product data and avoid the time of reading the product data by the chassis management module being timed out.

[0057] The embodiments of the present application disclose a key product data obtaining method, as shown in Figure 1 The method can include the following steps:

[0058] Step S11: reading, by a platform module of a cluster, new key product data from a backplane of a cluster device according to a first path, and saving the new key product data to a cache; the first path is in order of the platform module, a monitoring module, a storage chassis service module, and the backplane.

[0059] In the embodiments, after the cluster is created, the new key product data can be read from the backplane of the cluster device by the platform module according to the first path in the initialization process of the platform module of the cluster; the cluster can be a storage cluster, and at least one platform module (PL, Plateform), one monitoring module (EC, Engineering Change), one storage chassis service module (i.e., unified SCSI storage chassis service, OSES, Organic SCSI (Small Computer System Interface, small computer system interface) Enclosure service), and one chassis management module (Enclosure Mangement, EN) are included in one cluster. The backplane can be a double-sided backplane (Midplane), i.e., the backplane of a double-sided board, which is connected to a storage module.

[0060] The platform module reads the new key product data from the backboard according to the first path, that is, the platform module cannot directly read the data from the backboard, and the reading of the key product data (VPD, Vital Product Data) in the backboard is performed by the storage chassis service module through the platform module, the monitoring module and the storage chassis service module. After reading the new key product data, the data is temporarily stored in the cache. It can be understood that the key product data can include data such as name and ID, but there will be new field filling in the future, such as adding type information. At this time, the length of the entire page (page) is larger, so the reading time will be longer, which will exceed the specified reading time and timeout. After timeout, the storage will report an alarm and enter the storage service mode, causing the node to exit the cluster and affecting the stability of the business. Therefore, the new key product data is first read to the cache through the platform module, the monitoring module and the storage chassis service module, and then the new key product data is directly read from the cache.

[0061] In some embodiments, the above reading of the new key product data from the backboard of the cluster device by the platform module of the cluster according to the first path can include: sending the product data reading message to the monitoring module of the cluster by the platform module; generating a product data reading instruction based on the product data reading message by the monitoring module, and sending the product data reading instruction to the storage chassis service module; reading the new key product data from the backboard of each device in the cluster by the storage chassis service module, and saving the new key product data to the cache. That is, the platform module first sends the product data reading message to the monitoring module of the cluster; the monitoring module generates a product data reading instruction based on the product data reading message, and sends the product data reading instruction to the storage chassis service module; then, the storage chassis service module reads the new key product data from the backboard of each device in the cluster, and saves the new key product data to the cache.

[0062] In some embodiments, sending the product data reading message to the monitoring module of the cluster by the platform module described above can include the following steps: creating a communication channel between the platform module and the monitoring module of the cluster and configuring communication parameters; establishing an inter-process connection between the platform module and the monitoring module of the cluster based on the communication channel; writing the product data reading message into the communication channel by the platform module, so that the monitoring module obtains the product data reading message through the communication channel; obtaining the message receiving response fed back by the monitoring module after receiving the product data reading message by the platform module; closing the communication channel between the platform module and the monitoring module of the cluster according to the message receiving response; that is, according to the characteristics of the platform module in the cluster and the monitoring module of the cluster, the platform module sends the product data reading message to the monitoring module through inter-process communication (IPC, Inter-Process Communication). Further, sending the product data reading instruction to the storage chassis service module includes: initializing the serial port of the monitoring module and the storage chassis service module; establishing a connection between the monitoring module and the storage chassis service module based on the serial port; sending the product data reading instruction to the storage chassis service module by the monitoring module through the serial interface; obtaining the instruction receiving response fed back by the storage chassis service module after receiving the product data reading instruction by the monitoring module; that is, the monitoring module and the storage chassis service module use serial communication, and the monitoring module sends the product data reading instruction to the storage chassis service module through the serial bus, so that the storage chassis service module executes the reading of the new key product data according to the product data reading instruction. The serial bus can be an I2C (Inter-Integrated Circuit) bus.

[0063] Step S12: reading the initial key product data from the backplane of the cluster device through the chassis management module of the cluster according to a second path, and reading the new key product data from the cache through the chassis management module; the second path is in the order of the chassis management module, the storage chassis service module, and the backplane.

[0064] The initial key product data is read from the backplane of the cluster device through the chassis management module of the cluster according to a second path, and the second path is in the order of the chassis management module, the storage chassis service module, and the backplane; that is, the storage chassis service module is notified by the chassis management module to execute the reading of the initial key product data. At the same time, the new key product data is also read from the cache by the chassis management module. After obtaining the new key product data and the initial key product data, the chassis management module is used by the upper layer application.

[0065] That is, the chassis management module reads the key product data in two forms, one of which is to read the initial field of the key product data information to maintain the original page length for the upper application, and the other is to read the cached new key product data, that is, the key product data does not need to be read by increasing the length of the page, which reduces the reading time and solves the problem of reading key product data timeout caused by the large offset of the new field, and solves the problem of reading key product data timeout of the storage chassis service module caused by the new field of the key product data in the storage field.

[0066] In some embodiments, the chassis management module reads the initial key product data from the backplane of the cluster device according to the second path, which can include: the chassis management module issues a target data page request to the storage chassis service module after receiving the broadcast event reported by the storage chassis service module; the broadcast event is generated when the storage chassis server detects external signal interface changes, and the external signal interface changes are caused by the storage device driver loading process; the storage chassis service module reads the initial key product data from the backplane of the cluster device according to the target data page request, and reports the initial key product data to the chassis management module.

[0067] It can be understood that after the cluster is established, the loading of the SAS driver (Serial Attached SCSI driver, a driver for connecting storage devices) will cause changes in the PHY state (Physical, external signal interface), so the storage chassis service module will report a broadcast event. After receiving the broadcast event, the chassis management module issues a target data page request (such as pageD4 instruction) so that the storage chassis service module reads the key product information of the backplane according to the pageD4 instruction. Since the key product information is a shared device, the master storage chassis service module performs the reading of the key product information by default; the chassis management module and the storage chassis service module communicate according to the target protocol, and the chassis management module parses the information corresponding to pageD4 through the corresponding protocol for display by the upper application. The chassis management module issues a target data page request by sending the entire page length. If there is a new field in the key product information, and the offset distance of the field from the starting offset is far, it will inevitably increase the length of the entire page, and ultimately increase the time for the storage chassis service module to read the key product data, which may cause the event to exceed the specified reading time, and thus timeout, so that the storage node reports an alarm and enters the service mode, which cannot provide services externally.

[0068] Specifically, saving the new key product data to the cache can include: saving the new key product data to the cache of the monitoring module; correspondingly, reading the new key product data from the cache by the chassis management module, including: reading the new key product data from the cache of the monitoring module by the chassis management module, and sending the new key product data to the upper application. That is, the new key product data is temporarily stored in the cache corresponding to the monitoring module, and then the new key product data is read from the cache of the monitoring module by the chassis management module.

[0069] In some embodiments, characterized in that, before reading the new key product data from the backplane of the cluster device according to the first path by the platform module of the cluster, the method can further include: obtaining the offset address of the new key product data and the offset address of the initial key product data; correspondingly, reading the new key product data from the backplane of the cluster device according to the first path by the platform module of the cluster, including: reading the new key product data from the backplane of the cluster device according to the first path by the platform module according to the offset address of the new key product data; that is, the new key product data is read from the backplane by the platform module, the monitoring module and the storage chassis service module according to the offset address of the new key product data. Correspondingly, reading the initial key product data from the backplane of the cluster device according to the second path by the chassis management module of the cluster, including: reading the initial key product data from the backplane of the cluster device according to the second path by the chassis management module according to the offset address of the initial key product data; that is, the initial key product data is read from the backplane by the chassis management module and the storage chassis service module according to the offset address of the initial key product data.

[0070] Furthermore, after obtaining the offset address of the newly added key product data and the offset address of the initial key product data, and before reading the newly added key product data from the backplane of the cluster device according to the first path through the platform module of the cluster, the method may also include: determining the data volume of the newly added key product data according to the offset address of the newly added key product data to obtain the newly added data volume; determining the data volume of the initial key product data according to the offset address of the initial key product data to obtain the initial data volume; obtaining the total data volume based on the newly added data volume and the initial data volume; comparing the total data volume with the maximum single data reading volume; if the total data volume is If the sum of the above data amounts is less than the aforementioned maximum single data read amount, the initial key product data and newly added key product data are directly read from the cluster device's backplane via the second path using the cluster's chassis management module. If the sum of the above data amounts is greater than the aforementioned maximum single data read amount, the newly added key product data are read from the cluster device's backplane via the cluster's platform module via the first path, and the initial key product data are read from the cluster device's backplane via the cluster's chassis management module via the second path. The aforementioned maximum single data read amount is determined by determining the maximum single data read amount without timeout based on the specified key product data read time and data read speed. Flexible analysis of data reading methods is achieved through offset addresses, improving the flexibility of key product data reading.

[0071] Step S13: Based on the newly added key product data and the initial key product data, complete key product data is obtained.

[0072] Finally, based on reading the newly added key product data from the backplane through the platform module, monitoring module, and storage chassis service module, and reading the initial key product data from the backplane through the chassis management module and storage chassis service module, the complete key product data is obtained. For example Figure 2 As shown, after establishing a storage cluster, the platform module (PL) sends a product data read message (IPC message) to the monitoring module (EC module). Upon receiving the IPC message, the EC module sends a product data read command (DMP_READ command) via I2C to the storage chassis service module (OSES). OSES executes the DMP_READ command to read the VPD information from the backplane, using the EC module to cache the VPD information read by OSES. Subsequently, the EN module sends a PageD4 request to OSES to read the existing VPD information. The EN module parses the VPD information returned by PageD4 for use by upper-layer applications. The EN module reads the newly added VPD information from the EC cache for use by upper-layer applications. While ensuring complete critical product data, this reduces the time it takes to read newly added critical product data, lowering the overall read time. This prevents nodes from entering storage service mode and improves cluster stability.

[0073] As can be seen from the above, in the embodiment, the platform module of the cluster reads the newly added key product data from the backboard of the cluster device according to a first path, and saves the newly added key product data to a cache; the first path is in order of the platform module, the monitoring module, the storage chassis service module, and the backboard; the chassis management module of the cluster reads the initial key product data from the backboard of the cluster device according to a second path, and reads the newly added key product data from the cache through the chassis management module; the second path is in order of the chassis management module, the storage chassis service module, and the backboard; and the complete key product data is obtained based on the newly added key product data and the initial key product data. As can be seen, by using the platform module, the monitoring module, and the storage chassis service module to read the newly added key product data from the backboard of the cluster device and save the newly added key product data to the cache, when the chassis management module reads the key product data, the part of the newly added key product data is directly read from the cache, the reading of the newly added key product data does not occupy the resources of the chassis management module, the chassis management module only needs to read the initial key product data, the reading time of the key product data is reduced, and the time of the chassis management module reading the product data is prevented from being timed out.

[0074] Correspondingly, the embodiment of the application further discloses a key product data acquisition device, as shown in Figure 3 The device comprises:
