DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In the prior art, since key product data may have update operations, such as adding one or several types of parameters on the original basis; the newly added parameter fields will increase the length of the page to be read, which will increase the time to obtain key product data, often causing the time to obtain key product data to exceed the specified reading time, causing the node to report an alarm and enter the service mode, making it unable to provide services to the outside world, affecting cluster performance. In order to overcome the above technical problems, this application proposes a key product data acquisition method that can reduce the reading time of key product data and avoid the timeout of the chassis management module reading product data.

[0019] The present application embodiment discloses a method for obtaining key product data. Figure 1 As shown, the method may include the following steps: Step S11: read the newly added key product data from the backplane of the cluster device through the cluster platform module according to the first path, and save the above-mentioned newly added key product data to the cache; the above-mentioned first path is platform module, monitoring module, storage chassis service module, and backplane in order.

[0020] In this embodiment, after the cluster is created, during the initialization process of the platform module of the cluster, the newly added key product data can be read from the backplane of the cluster device according to the first path through the platform module; the cluster can be a storage cluster, and a cluster has at least one platform module (PL, Plateform), one monitoring module (EC, EngineeringChange), one storage chassis service (i.e., unified SCSI storage chassis service, OSES, Organic SCSI (SmallComputer System Interface, Small Computer System Interface) Enclosure service) module, and one chassis management module (Enclosure Mangement, EN). The backplane can be a double-sided backplane (Midplane), that is, a backplane of a double-sided plug-in board, connected to the storage module.

[0021] The platform module specifically reads the newly added key product data from the backplane according to the first path, that is, the platform module cannot read data directly from the backplane, and the storage chassis service module performs the reading of the key product data (VPD, Vital Product Data) in the backplane through the platform module, the monitoring module and the storage chassis service module. After the newly added key product data is read, the data is temporarily stored in the cache. It can be understood that the key product data may include data such as name and ID, but there will be new field filling later, such as adding type information. At this time, the reading time will be longer due to the increase in the length of the entire page (page), and the reading time will exceed the specified reading time and time out. After the timeout, the storage will report an alarm and enter the storage service mode service mode, causing the node to exit the cluster and affect the stability of the business. Therefore, the newly added key product data is first read into the cache through the platform module, the monitoring module and the storage chassis service module, and then the newly added key product data can be directly read from the cache.

[0022] In some embodiments, the above-mentioned reading of the newly added key product data from the backplane of the cluster device through the platform module of the cluster according to the first path may include: sending the above-mentioned product data reading message to the monitoring module of the cluster through the above-mentioned platform module; generating a product data reading instruction based on the above-mentioned product data reading message through the above-mentioned monitoring module, and sending the above-mentioned product data reading instruction to the storage chassis service module; reading the newly added key product data from the backplane of each device in the cluster through the above-mentioned storage chassis service module, and saving the above-mentioned newly added key product data to the cache. That is, firstly, the platform module sends a product data reading message to the monitoring module of the cluster; the monitoring module generates a product data reading instruction based on the above-mentioned product data reading message, and sends the above-mentioned product data reading instruction to the storage chassis service module, and then, the storage chassis service module reads the newly added key product data from the backplane of each device in the cluster, and saves the above-mentioned newly added key product data to the cache.

[0023] In some embodiments, sending the product data reading message to the monitoring module of the cluster through the platform module may 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 through 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 through 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 and the monitoring module of the cluster within the cluster, by establishing inter-process communication (IPC, Inter-Process Communication) between the platform module and the monitoring module, the platform module sends the product data reading message to the monitoring module through inter-process communication. Further, the product data reading instruction is sent to the storage chassis service module, including: initializing the serial ports 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; using the monitoring module to send the product data reading instruction to the storage chassis service 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 through the monitoring module; that is, serial communication is adopted between the monitoring module and the storage chassis service module, 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 newly added key product data according to the product data reading instruction. Among them, the serial bus can be specifically an I2C (Inter-Integrated Circuit) bus.

[0024] Step S12: read the initial key product data from the backplane of the cluster device through the chassis management module of the cluster according to the second path, and read the newly added key product data from the cache through the chassis management module; the second path is chassis management module, storage chassis service module, and backplane in sequence.

[0025] The chassis management module of the cluster reads the initial key product data from the backplane of the cluster device according to the second path. The second path is the chassis management module, the storage chassis service module, and the backplane in order; that is, the chassis management module notifies the storage chassis service module, and the storage chassis service module performs the reading of the initial key product data. At the same time, the chassis management module is also used to read the above-mentioned newly added key product data from the above-mentioned cache. After the chassis management module obtains the newly added key product data and the initial key product data, it is provided for use by the upper-layer application.

[0026] That is to say, the chassis management module reads key product data in two forms. One is to maintain the original page length to read the key product data information of the initial field for use by upper-level applications; the other is to read the newly added key product data in the cache, that is, there is no need to increase the page length to read the key product data, which reduces the reading time and can solve the problem of timeout in reading key product data due to excessive offset of the newly added field. It solves the problem of timeout in reading key product data by the storage chassis service module due to the newly added fields of key product data in the storage field.

[0027] In some embodiments, reading the initial key product data from the backplane of the cluster device according to the second path through the chassis management module of the cluster may include: after receiving the broadcast event reported by the storage chassis service module, the chassis management module sends a target data page request to the storage chassis service module; the broadcast event is generated when the storage chassis server detects a change in the external signal interface, and the change in the external signal interface is caused by the storage device driver loading process; reading the initial key product data from the backplane of the cluster device according to the target data page request through the storage chassis service module, and reporting the initial key product data to the chassis management module.

[0028] It is understandable that after the cluster is established, the storage chassis service module will report a broadcast event because the loading of the SAS driver (Serial Attached SCSI driver, a driver for connecting storage devices) will cause a change in the PHY state (Physical, external signal interface). After receiving the broadcast event, the chassis management module sends a target data page request (such as the pageD4 instruction) so that the storage chassis service module can read the key product information of the backplane according to the pageD4 instruction. Since the key product information is a shared device, the reading of the key product information is performed by the main storage chassis service module by default; the chassis management module communicates with the storage chassis service module according to the target protocol, and the chassis management module parses the corresponding information of pageD4 through the corresponding protocol for display by the upper-level application. The chassis management module sends the target data page request by sending the entire page length. If there is a new field in the key product information and the offset of the field is far from the starting offset, it will inevitably increase the length of the entire page, which will eventually increase the time it takes for the storage chassis service module to read key product data. This may cause the event to exceed the specified reading time and then time out, causing the storage node to report an alarm and enter service mode and be unable to provide external services.

[0029] Specifically, saving the newly added key product data to the cache may include: saving the newly added key product data to the cache of the monitoring module; correspondingly, reading the newly added key product data from the cache through the chassis management module includes: reading the newly added key product data from the cache of the monitoring module through the chassis management module, and sending the newly added key product data to the upper layer application. That is, temporarily storing the newly added key product data in the cache corresponding to the monitoring module, and then the chassis management module reads the newly added key product data from the cache of the monitoring module.

[0030] In some embodiments, it is characterized in that before the platform module of the cluster reads the newly added key product data from the backplane of the cluster device according to the first path, it may also include: obtaining the offset address of the newly added key product data and the offset address of the initial key product data; accordingly, the platform module of the cluster reads the newly added key product data from the backplane of the cluster device according to the first path, including: reading the newly added 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 newly added key product data; that is, reading the newly added key product data from the backplane by using the platform module, the monitoring module, and the storage chassis service module according to the offset address of the newly added 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 includes: 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 according to the offset address of the initial key product data; that is, reading the initial key product data from the backplane by using the chassis management module and the storage chassis service module according to the offset address of the initial key product data.

[0031] Further, 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, it can 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 If the sum of the above data volumes is less than the above-mentioned maximum single data read volume, the initial key product data and the newly added key product data are directly read from the backplane of the cluster device according to the second path using the chassis management module of the cluster; if the sum of the above data volumes is greater than the above-mentioned maximum single data read volume, the newly added key product data is read from the backplane of the cluster device according to the first path through the platform module of the cluster, and the initial key product data is read from the backplane of the cluster device according to the second path through the chassis management module of the cluster; the determination process of the above-mentioned maximum single data read volume is: according to the specified key product data reading time and data reading speed, determine the maximum single data read volume without timeout. The data reading method is flexibly analyzed through the offset address to improve the flexibility of key product data reading.

[0032] Step S13: Based on the newly added key product data and the initial key product data, complete key product data is obtained.

[0033] 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. Figure 2 As shown in the figure, after the storage cluster is established, the platform module PL sends a product data read message (IPC message) to the monitoring module EC module. After receiving the IPC message, the EC module sends a product data read instruction (DMP_READ instruction) to the storage chassis service module OSES through I2C. OSES executes the DMP_READ instruction to read the VPD information from the backplane and uses EC to cache the VPD information read by OSES. Subsequently, the EN module sends a PageD4 request to OSES to read the original VPD information. The EN module parses the VPD information returned by PageD4 for use by upper-layer applications. The newly added field is the VPD information cached by EC read by the EN module for use by upper-layer applications. On the basis of ensuring the acquisition of complete key product data, the reading time of the newly added key product data is saved, and the overall reading time of the key product data is reduced, thereby avoiding the node from entering the storage service mode and improving the stability of cluster operation.

[0034] As can be seen from the above, in this embodiment, the platform module of the cluster reads the newly added key product data from the backplane of the cluster device according to the first path, and saves the newly added key product data to the cache; the first path is the platform module, the monitoring module, the storage chassis service module, and the backplane in order; the chassis management module of the cluster reads the initial key product data from the backplane of the cluster device according to the second path, and reads the newly added key product data from the cache through the chassis management module; the second path is the chassis management module, the storage chassis service module, and the backplane in order; based on the newly added key product data and the initial key product data, the complete key product data is obtained. It can be seen that by using the platform module, the monitoring module, and the storage chassis service module to read the newly added key product data from the backplane of the 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 can be directly read from the cache, and the reading of the newly added key product data will not occupy the resources of the chassis management module. The chassis management module only needs to read the initial key product data, which reduces the reading time of the key product data and avoids the timeout of the chassis management module reading the product data.

[0035] Correspondingly, the embodiment of the present application also discloses a key product data acquisition device, see Figure 3 As shown, the device comprises: A newly added key product data acquisition module 11 is used to read the newly added key product data from the backplane of the cluster device through the platform module of the cluster according to the first path, and save the newly added key product data to the cache; the first path is the platform module, the monitoring module, the storage chassis service module, and the backplane in order; The initial key product data acquisition module 12 is used to read the initial key product data from the backplane of the cluster device through the chassis management module of the cluster according to the second path, and read the newly added key product data from the cache through the chassis management module; the second path is the chassis management module, the storage chassis service module, and the backplane in order; The complete key product data determining module 13 is used to obtain the complete key product data based on the newly added key product data and the initial key product data.

[0036] As can be seen from the above, in this embodiment, the platform module of the cluster reads the newly added key product data from the backplane of the cluster device according to the first path, and saves the newly added key product data to the cache; the first path is in the order of platform module, monitoring module, storage chassis service module, and backplane; the chassis management module of the cluster reads the initial key product data from the backplane of the cluster device according to the second path, and reads the newly added key product data from the cache through the chassis management module; the second path is in the order of chassis management module, storage chassis service module, and backplane; based on the newly added key product data and the initial key product data, complete key product data is obtained. It can be seen that by using the platform module, monitoring module, and storage chassis service module to read the newly added key product data from the backplane of the 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 can be directly read from the cache, and the reading of the newly added key product data will not occupy the resources of the chassis management module.
