Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

For each storage server, two or four controller hardware are often combined in a chassis with the height of 2U or 4U, and mirror image redundancy and backup are arranged among the controllers in the chassis for data access, operation and storage, so that safe and reliable operation of the servers is guaranteed.

In the same frame, each controller is regarded as a data synchronization node, and a plurality of controllers jointly form a data synchronization network, and hardware management data flows on nodes in the synchronization network.

FIG. 1 is a block diagram of a prior art two-control hardware architecture of a storage server. As shown in fig. 1, two controllers in the storage server are a controller a and a controller B, complex programmable logic devices (Complex Programmable Logic Device, CPLDs) and BMCs are respectively arranged in the controller a and the controller B, the two CPLDs coordinate data synchronization between the two BMCs through a general purpose input/Output (GPIO) heartbeat signal, and the two BMCs are in communication connection through an I2C synchronization main link and an I2C synchronization standby link.

Fig. 2 is a schematic flow chart of a data synchronization method according to an embodiment of the present invention. As shown in fig. 2, there is provided a data synchronization method applied to a baseboard management controller of a transmitting end, the baseboard management controller including a field replaceable unit FRU management module and a data synchronization module, the data synchronization method including the steps of: step 210, step 220, step 230 and step 240. The method flow steps are only one possible implementation of the invention.

The baseboard management controller BMC is usually a separate computer board, and is installed on a server motherboard to manage server hardware. The BMC may also monitor the health of the server, such as temperature, voltage, fan speed, etc. In addition, the BMC may also provide remote management functions through a remote management interface, such as a Smart platform management interface (Intelligent Platform Management Interface, IPMI), to allow an administrator to remotely monitor and manage servers.

The field replaceable unit FRU refers to a component that can be replaced in the field while the electronic device is being repaired and serviced. These components are typically wearing parts or parts that need to be replaced frequently, such as batteries, hard disks, fans, etc. FRUs can help reduce maintenance costs and maintenance time for equipment because they can be easily replaced in the field without the need to send the entire equipment back to the manufacturer for repair.

Step 210, the FRU management module acquires the data to be synchronized and determines the type of the data to be synchronized.

Wherein the data to be synchronized includes, but is not limited to, the following: server hardware status data such as central processing unit (Central Processing Unit, CPU) temperature, fan speed, voltage, etc.; a system event log comprising system crashes, power supply anomalies, temperature anomalies and the like; user rights and configuration information such as user account, password, network configuration, etc.; remote control commands such as restarting the server, modifying BIOS settings, etc.

Optionally, the data to be synchronized may be classified by identifying information such as format, content, keywords, etc. of the data, and may be classified into text data and image data according to the format, and may be classified into static data and dynamic data according to the temporal state.

It can be understood that the type of the data to be synchronized is determined by acquiring the data to be synchronized, so that the data to be synchronized of different types can be classified and processed conveniently, and the data synchronization is performed in a proper mode based on the type of the data to be synchronized.

And 220, the FRU management module processes the data to be synchronized according to the type of the data to be synchronized.

It can be understood that for different types of data to be synchronized, different processing modes are adopted for processing, such as adding a synchronization state identifier or a serial number, so that the subsequent quick and efficient determination of the synchronization data from the processed data to be synchronized is facilitated, and the accuracy and reliability of the synchronization data are improved.

And 230, determining synchronous data from the processed data to be synchronized by the FRU management module under the condition of running to the data synchronization logic, and sending the synchronous data to the data synchronization module.

It can be understood that the data to be synchronized is selected from the processed data to be synchronized and sent to the data synchronization module, and the data which is synchronized and the data which is not subjected to state change are filtered from the processed data to be synchronized, so that the accuracy and the reliability of the synchronized data can be further improved, and the efficiency of data synchronization is improved.

Step 240, a data synchronization module schedules the synchronous data, determines a transmission link of the synchronous data, and transmits the synchronous data to a baseboard management controller of the receiving end through the transmission link.

For scheduling and transmitting synchronous data, the following aspects are generally considered:

1) Priority of data: for different types of data, different priorities may exist, and a transmission sequence needs to be determined according to the priorities, so that low-priority data is prevented from being blocked by high-priority data;

2) Network bandwidth and delay: network bandwidth and delay are also important factors for determining the data transmission sequence, and the time for transmitting the data needs to be determined according to the network conditions, the data quantity and other factors;

3) Synchronization accuracy: the accuracy of the synchronization data also needs to be considered, and if high accuracy synchronization is required, higher bandwidth, lower latency network devices may need to be used, as well as finer scheduling algorithms;

4) Data retransmission and loss handling: during data transmission, retransmission and loss may occur, and a corresponding mechanism is required to deal with these problems.

By comprehensively considering the factors, a corresponding scheduling algorithm can be designed to schedule the synchronous data and determine the transmission link of the synchronous data so as to realize the efficient, accurate and stable transmission of the synchronous data.

In the embodiment of the invention, the FRU management module is used for acquiring the data to be synchronized, determining the type of the data to be synchronized, processing the data to be synchronized according to the type of the data to be synchronized, determining the synchronous data from the processed data to be synchronized under the condition of running to the data synchronization logic, and transmitting the synchronous data to the data synchronization module; the data synchronization module is used for scheduling the synchronous data, a transmission link of the synchronous data is determined, and the synchronous data is transmitted to the baseboard management controller of the receiving end through the transmission link, so that the time delay of data synchronization among different BMCs can be reduced, and the instantaneity and the accuracy of the synchronous data are improved.

It should be noted that each embodiment of the present invention may be freely combined, exchanged in order, or separately executed, and does not need to rely on or rely on a fixed execution sequence.

In some embodiments, the types include static data and dynamic data;

the FRU management module stores the static data in the memory of the FRU management module, and a static data synchronization status word is reserved in the FRU management module and used for indicating whether the static data are synchronized or not;

the FRU management module performs stripe region division and numbering on the dynamic data, and adds check bits, and synchronous copies of the dynamic data are established in the memory of the FRU management module.

Wherein, the static data refers to data which does not change along with time, and includes data which is not modified after the measurement is completed, such as user account, network configuration, etc.; the dynamic data refers to data that changes with time, i.e. data monitored by the FRU management module in real time, such as CPU temperature, fan speed, voltage, etc.

Wherein, the static data synchronous status word is "yes" or "no", the "yes" indicates that the static data is synchronous, and the "no" indicates that the static data is not synchronous.

Under the condition that the total dynamic data amount is certain, dividing the whole data area according to the data length, adding numbers and checks to each area, wherein the dividing basis is the bandwidth of a data transmission channel, and the data amount of the stripe is ensured to be smaller than the data amount which can be loaded by the maximum transmission packet as far as possible.

Fig. 3 is an example of processed static data and dynamic data provided by an embodiment of the present invention. As shown in fig. 3, the processed static data may be "[ data separation character 5 bytes ]; [ data synchronization State_No ]; static data "or" [ data separation character 5 bytes ]; [ data synchronization status_yes ]; the dynamic data is divided into a plurality of stripes, including a data field 1, a data field 2, a data field 3, a data field N, and each stripe has a corresponding number and check field.

It can be understood that the FRU management module stores the static data in the memory of the FRU management module, and reserves the static data synchronization status word in the FRU management module, so as to determine whether to carry the static data according to the static data synchronization status word when the static data is sent; the FRU management module is used for dividing and numbering the stripe regions of the dynamic data and adding check bits, and synchronous copies of the dynamic data are established in the memory of the FRU management module, so that the dynamic data of different stripes can be conveniently compared with the data in the synchronous copies, and the data regions needing to be synchronized are determined according to the state changes of the different stripes, so that the data synchronization efficiency is improved, and the data synchronization delay is reduced.

In some embodiments, the FRU management module, when running to the data synchronization logic, determines synchronization data from the processed data to be synchronized, comprising:

under the condition that the FRU management module runs to the data synchronization logic, determining whether the static data synchronization status word is the static synchronization data or not from the processed static data;

the FRU management module encapsulates the static synchronous data according to a static data frame format, and takes the encapsulated static synchronous data as synchronous data, wherein the static data frame format comprises a data separation field, a static data synchronous state word and a static data segment.

Illustratively, the encapsulated static synchronization data is "[ data separation character 5 bytes ]; [ data synchronization State_No ]; static data).

It can be understood that under the condition that the FRU management module runs to the data synchronization logic, the FRU management module determines whether the static data synchronization status word is the static synchronization data or not from the processed static data, encapsulates the static synchronization data according to the static data frame format, uses the encapsulated static synchronization data as the synchronization data, and further facilitates screening out the static data which is not synchronized, uses the encapsulated static synchronization data as the synchronization data for synchronization processing, and avoids repeated synchronization of the synchronized static data.

under the condition of running to the data synchronization logic, the FRU management module determines whether synchronous copies of dynamic data exist in the local memory;

if synchronous copies of the dynamic data exist in the local memory, determining dynamic synchronous data which changes compared with the existing synchronous copies from the processed dynamic data, and taking the dynamic synchronous data as synchronous data;

and if the synchronous copy of the dynamic data does not exist in the local memory, the processed dynamic data is used as synchronous data.

It should be noted that, the synchronous copy of the dynamic data refers to that in the storage system, in order to realize reliability and high availability of the data, the data is backed up on a plurality of nodes, so that when the primary node fails, the primary node can be automatically switched to the standby node, and continuous operation of the system is ensured. The data on the standby nodes are synchronous copies, and the data on the standby nodes are synchronous with the data on the main nodes, so that the consistency of the data is ensured. When the data on the master node changes, the synchronous copies are updated correspondingly, so that the synchronism of the data is ensured.

Optionally, when the FRU management module continues to operate and the dynamic data is changed and updated, the processed dynamic data is obtained, and when the processed dynamic data is compared with the synchronous copy of the dynamic data existing in the local memory, some algorithms, such as hash value comparison or comparison, can be used to record the number of the changed data area if the field values of the two objects are the same.

It can be understood that by determining whether a synchronous copy of the dynamic data already exists in the local memory, if so, the processed dynamic data is compared with the synchronous copy, so that the changed dynamic synchronous data can be conveniently determined, the dynamic synchronous data is used as synchronous data, and if not, the processed dynamic data is used as synchronous data, so that the reliability and accuracy of the synchronous data can be improved.

Fig. 4 is a schematic flow chart of a baseboard management controller for scheduling synchronous data, determining a transmission link of the synchronous data, and transmitting the synchronous data to a receiving end through the transmission link according to an embodiment of the present invention. As shown in fig. 4, in some embodiments, the data synchronization module in step 240 schedules the synchronization data, determines a transmission link of the synchronization data, and transmits the synchronization data to the baseboard management controller of the receiving end through the transmission link, including:

Step 241, determining a sending interface of synchronous data according to the real-time requirement of the FRU management module, where the sending interface includes a synchronous interface or an asynchronous interface.

Fig. 5 is a schematic diagram of a baseboard management controller according to an embodiment of the present invention. As shown in fig. 5, the BMC includes a FRU management module and a data synchronization module. The FRU management module is used for acquiring data to be synchronized from different service modules, and calling a sending interface according to the requirement on the real-time property of the data to determine the sending interface (namely a synchronous interface or an asynchronous interface) of the synchronous data. The data synchronization module comprises a synchronization interface, an asynchronous interface and a sending data pool, if the synchronization interface is selected for data sending, the data synchronization module can schedule the synchronization data to determine a sending link (namely a main link or a standby link) of the synchronization data, if the asynchronous interface is selected for data sending, the synchronization data can be summarized in the sending data pool first, and then the physical link is called for sending the synchronization data.

The synchronous interface is to wait for receiving a response after sending the request and then perform the next operation, which requires waiting time, but ensures the accuracy of the data.

The asynchronous interface is to directly perform the next operation without waiting for a response after sending the request, which can save time, but may cause inaccurate data.

Optionally, different FRU management modules select different interfaces to complete data synchronization according to the real-time property of the data, select asynchronous interfaces with low real-time property and select synchronous interfaces with high real-time property.

It will be appreciated that determining the sending interface of the synchronization data is to ensure real-time and accuracy of the data, and the selection of which interface to use depends on the specific requirements and application scenario.

In step 242, when the synchronization interface is called to send the synchronization data, a priority field is added to the header frame of the synchronization data, the value of the priority field is determined by querying a priority table based on the serial number of the FRU management module, and the priority table is pre-established in the data synchronization module according to the real-time performance and the data volume of each FRU management module.

Step 243, scheduling the synchronous data according to the priority field, determining a transmission link of the synchronous data, and transmitting the synchronous data to the baseboard management controller of the receiving end through the transmission link.

Optionally, the sending link may be a main link or a standby link, and the scheduling algorithm may be used to schedule the synchronous data according to the idle condition of the link, so as to determine the sending link of the synchronous data.

It can be understood that according to the requirement of the FRU management module on the real-time performance of the data, the sending interface of the synchronous data is determined, when the synchronous interface is called to send the synchronous data, the priority field is added in the data header frame of the synchronous data, the synchronous data is scheduled according to the priority field, the sending link of the synchronous data is determined, and the synchronous data is sent to the baseboard management controller of the receiving end through the sending link, so that the time delay of the data synchronization can be reduced, the efficiency of the data synchronization can be improved, and the real-time performance and the accuracy of the synchronous data can be ensured.

In some embodiments, the method further comprises:

Alternatively, when the standby link is idle and can work normally, the standby link may be used to send synchronous data, and then the high-priority data packet is sent first, and then the low-priority data packet is sent.

It can be understood that when the asynchronous interface is called to send synchronous data, the synchronous data is summarized in a sending data pool of the data synchronous module, an asynchronous data sending thread of the data synchronous module reads a plurality of data packets in the sending data pool at one time, prioritizes the plurality of data packets, calls a physical link according to the sequencing result to send the read data packets in sequence, so that the standby link is convenient to fully utilize, and the real-time performance of data synchronization can be effectively improved.

under the condition that the main link and the standby link are normal, determining the standby link as a transmission link of synchronous data;

and under the condition that any link is abnormal, determining the transmission link of the synchronous data by adopting a fair competition mode.
