Description

Technical Field

[0001] The present invention relates to the field of storage technology, and in particular to a storage node management method, device and equipment. Background Art

[0002] At present, in order to improve data reliability and disaster recovery capabilities, storage devices usually adopt a multi-node design; by distributing data on multiple nodes in the storage device, even if some nodes fail, other nodes can still store and provide data, thereby ensuring data reliability and integrity. Storing data on multiple nodes can achieve data disaster recovery backup. When a node or data center fails, data can be restored from other nodes or data centers to ensure business continuity.

[0003] However, since each node in the storage device is an independent entity, each node may be equipped with memory of different capacity, speed or even brand. This inconsistency in memory specifications will increase the complexity of resource management, requiring administrators to track the memory configuration of each node and ensure that memory differences are taken into account when allocating tasks or data, which is prone to uneven resource allocation or inefficiency. In addition, due to the inconsistency of memory specifications, the memory limitations of some nodes will become a bottleneck, resulting in a decline in overall system performance. In addition, data exchange and synchronization between nodes may encounter mismatches in data size, format or processing speed, increasing the risk of data consistency and the difficulty of fault recovery. Therefore, how to reduce the difficulty of managing and maintaining multiple storage nodes in storage devices, reduce operation and maintenance costs, and improve system stability is an urgent problem to be solved today.

[0048] 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 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.

[0049] Please refer to Figure 1 , Figure 1 A flowchart of a storage node management method provided by an embodiment of the present invention. The method may include:

[0050] Step 101: Obtain memory specification information of each storage node in the storage device; wherein the memory specification information includes at least one of node memory capacity, memory brand, memory model, and memory speed.

[0051] It is understandable that the storage node in this embodiment can be a node set in a storage device in a storage system, such as multiple storage nodes set in a storage device in a centralized storage system, or multiple storage nodes set in a storage device in a distributed storage system. This embodiment is demonstrated by taking the memory consistency management of multiple storage nodes in a storage device as an example. The management of storage nodes in other storage devices in a storage system (such as a distributed storage system) can be implemented in the same or similar manner as the method provided in this embodiment, and this embodiment does not impose any restrictions on this.

[0052] Correspondingly, in this embodiment, a plurality of storage nodes, that is, 2 or more storage nodes, may be set in the storage device. The memory specification information in this embodiment may be information related to the memory specifications of each storage node in the storage device. The specific content of the memory specification information in this embodiment may be set by the designer according to the practical scenario and user needs. For example, the memory specification information may include the memory capacity of the storage node (i.e., the node memory capacity), such as 256G, 512G, 1024G or 2048G and other effective memory specifications, to limit the balance of memory capacity of all storage nodes in the storage device; the memory specification information may also include the memory brand and memory model of the storage node, to ensure the compatibility of all storage nodes in the storage device, and avoid compatibility issues that may exist in memory bars of different brands and models; the memory specification information may also include the memory rate of the storage node, such as 2400MHz of DDR4 (fourth-generation double-rate synchronous dynamic random access memory), to ensure the consistency of the memory rate of all storage nodes in the storage device and optimize the overall performance.

[0053] It should be noted that the method provided in this embodiment can be applied to storage devices, that is, each storage device can detect and warn the memory specifications of all storage nodes belonging to a certain storage system set by itself, so as to achieve memory consistency management among these storage nodes. The method provided in this embodiment can also be applied to the management node (such as a server) of the storage system, such as the management node of a distributed storage system can detect and warn the memory specifications of all storage nodes in each storage device, so as to achieve memory consistency management among all storage nodes of each storage node. This embodiment does not impose any restrictions on this.

[0054] Correspondingly, the specific method of obtaining the memory specification information of each storage node in the storage device in this step can be set by the designer according to practical scenarios and user needs. For example, when the method provided in this embodiment is applied to a storage device, the storage device can monitor the memory specification information of each storage node during the boot-up phase and / or when joining a storage system (i.e., a cluster), so as to promptly discover storage nodes that do not meet the predicted memory specification requirements (i.e., abnormal nodes) and issue an alarm; that is, the processor of the storage device can detect the memory specification information of each storage node during the boot-up process; it can also detect the memory specification information of each storage node when joining a storage system; wherein the storage node is set in the storage device.

[0055] Accordingly, when the method provided in this embodiment is applied to a management node of a storage system, the management node can monitor the memory specification information of all storage nodes in the storage device to be added to the storage system when the storage device is added to the storage system.

[0056] Step 102: Check abnormal nodes in the storage nodes according to the memory specification information and the predicted memory specification requirements corresponding to each storage node; wherein the predicted memory specification requirements corresponding to all storage nodes in the same storage device are the same.

[0057] It is understandable that the predicted memory specification requirements in this embodiment can be the memory specification requirements of the pre-set storage node. The specific content of the predicted memory specification requirements in this embodiment can be set by the designer or user according to the practical scenario and user needs, such as being set corresponding to the memory specification information. For example, the predicted memory specification requirements may include a preset node memory capacity range for limiting the node memory capacity, such as the range between the preset upper and lower limits of the memory capacity; it may also include a preset memory brand and memory model data set for limiting the memory brand and memory model, so as to automatically compare and limit the memory brand and model that can be used by each storage node in the storage device through a pre-established compatibility database (i.e., a preset memory brand and memory model data set) to avoid problems caused by incompatibility; it may also include a preset memory rate range for limiting the memory rate, such as a preset memory rate lower limit (e.g., 2300MHz), to ensure the consistency of the memory rate of each storage node in the storage device.

[0058] Correspondingly, in this embodiment, the predicted memory specification requirements corresponding to all storage nodes in the same storage device can be the same, that is, the predicted memory specification requirements corresponding to all storage nodes of a storage system in the same storage device can be the same, so as to realize memory consistency management among all storage nodes in the storage node. For example, all storage nodes in a storage device in a centralized storage system can adopt the same predicted memory specification requirement. All storage nodes in each storage device in a distributed storage system can adopt the same predicted memory specification requirement; further, the storage nodes of all storage devices in the distributed storage system can adopt the same predicted memory specification requirement to ensure the memory consistency of all storage nodes in the system, realize memory consistency management of all storage nodes in the distributed storage system, avoid the process of separately configuring and monitoring each storage node in the related technology, and improve maintenance efficiency and accuracy.

[0059] Among them, the specific process of the processor in this step checking the abnormal nodes in the storage nodes according to the memory specification information and the predicted memory specification requirements corresponding to each storage node can be set by the designer. For example, the processor can detect the memory specification information of all storage nodes in the storage device sequentially or simultaneously to determine the abnormal nodes among all storage nodes. For example, when the memory specification information includes node memory capacity, memory brand, memory model and memory rate, the processor in this step can determine whether the node memory capacity in the memory specification information of the current storage node is within the target memory capacity range; wherein, the current storage node is any storage node, and the target memory capacity range is the preset node memory capacity range in the predicted memory specification requirements corresponding to the current storage node; if it is not within the target memory capacity range, the current storage node is determined as an abnormal node; if it is within the target memory capacity range, it is determined whether the memory brand and memory model in the memory specification information of the current storage node meet the target compatibility range; wherein, the target compatibility range is the preset memory brand and memory model data set in the predicted memory specification requirements corresponding to the current storage node; if it does not meet the target compatibility range, the current storage node is determined as an abnormal node; if it meets the target compatibility range, it is determined whether the memory rate in the memory specification information of the current storage node reaches the target memory rate; wherein, the target memory rate is the preset memory rate lower limit in the predicted memory specification requirements corresponding to the current storage node; if the target memory rate is not reached, the current storage node is determined as an abnormal node; if the target memory rate is reached, the current storage node is determined as a normal node, and the next storage node can be detected.

[0060] For example, if Figure 2 and Figure 3 As shown, the storage device can use the capacity detection module, brand detection module, model detection module and speed detection module in the detection module to compare the node memory capacity, memory brand, memory model and memory speed of the monitored storage node with the pre-set memory specification requirements during the startup phase and when the storage node joins the cluster. When an inconsistent storage node (i.e., an abnormal node) is detected, an alarm is reported through the alarm module.

[0061] Step 103: If an abnormal node is detected, abnormal alarm information is generated and sent to the target terminal.

[0062] In this embodiment, the target terminal may be a terminal device corresponding to the storage device where the abnormal node is located, that is, a terminal device of a manager of the storage device. In this step, when the processor detects a storage node (that is, an abnormal node) that does not meet the predicted memory specification requirements in the storage device, it may generate an alarm message corresponding to the storage node (that is, abnormal alarm message), and send the alarm message to the target terminal to remind the manager to handle it in time.

[0063] Correspondingly, the specific method for the processor to generate and send abnormal alarm information to the target terminal in this step can be set by the designer according to practical scenarios and user needs. For example, the processor can send the abnormal alarm information to the target terminal through communication methods such as email, SMS or phone; Figure 2 and Figure 3 As shown, once the detection module finds an abnormal node in the storage device, the alarm mechanism of the alarm module can be triggered immediately, so that the alarm module can use the internal user notification module to remind the storage device administrator through email notification, SMS reminder, or telephone voice reminder, ensuring that the administrator can respond quickly. The processor can also use the graphical user interface (GUI) of the dynamic memory configuration platform (DMP) to display abnormal alarm information. For example, the processor can use the dynamic memory configuration platform to display the generated abnormal alarm information to the graphical user interface logged in by the target terminal, so as to allow the administrator to view the abnormal alarm information in the graphical user interface through the integrated DMP, so that the administrator can monitor and manage the storage system through a unified interface and tools, greatly reducing the operation and maintenance costs; and because the data format and synchronization protocol between the storage nodes are consistent, the administrator does not need to perform separate operations on each storage node when handling faults or performing upgrades, thereby improving the efficiency and accuracy of maintenance; as shown in FIG. Figure 2 and Figure 3 As shown, the processor can use the GUI interaction module to display abnormal alarm information on the graphical user interface for target terminal login provided by the dynamic memory configuration platform, so that the management personnel can operate and view the detailed abnormal alarm information on the graphical user interface.

[0064] Accordingly, the present embodiment does not limit the specific content of the abnormal alarm information. For example, when the abnormal alarm information is displayed in the graphical user interface of the dynamic memory configuration platform, the abnormal alarm information may include detailed alarm information and repair suggestion information; wherein the detailed alarm information includes at least one of the alarm level, the event, the node location, the abnormal type and the impact range; for example, the graphical user interface may display a list of all current alarms, including the alarm level, the event and the node location, as well as more detailed abnormal type, impact range and repair suggestion information (such as Figure 2 The DMP repair process in the system helps administrators quickly locate and repair problems, such as replacing memory modules and adjusting memory speed, to further improve repair efficiency and enhance system stability.

[0065] It should be noted that, in this embodiment, when the processor detects an abnormal node, it can also control the abnormal node to enter a service mode to prevent the abnormal node from joining the storage system and ensure the reliability of the storage system.

[0066] Correspondingly, the method provided in this embodiment may also include a real-time monitoring process of the storage nodes added to the storage system in the storage device, so as to detect and warn the storage nodes with memory failure (i.e., faulty nodes). For example, the storage device detects the operating status information of each target storage node; wherein the target storage node is a storage node added to the storage system in the storage device, and the operating status information includes at least one of the memory health status, node memory capacity, and memory rate; according to the operating status information and the predicted memory specification requirements corresponding to each target storage node, the faulty nodes in the target storage node are checked; if a faulty node is detected, a fault alarm information is generated and sent to the target terminal; if no faulty node is detected, the process can be directly terminated or the operating status information of each target storage node can be detected next time.

[0067] Correspondingly, for the above-mentioned specific method of checking the faulty nodes in the target storage nodes based on the operating status information and the predicted memory specification requirements corresponding to each target storage node, it can be set up in a similar manner to the abnormal node checking process in step 102, such as the processor can determine whether the memory health status in the operating status information of the current storage node is healthy; if not, the current storage node is determined as a faulty node; if it is healthy, it is determined whether the node memory capacity in the operating status information of the current storage node is within the target memory capacity range; if not within the target memory capacity range, the current storage node is determined as a faulty node; if it is within the target memory capacity range, it is determined whether the memory rate in the operating status information of the current storage node reaches the target memory rate; if the target memory rate is not reached, the current storage node is determined as a faulty node; if the target memory rate is reached, the current storage node is determined as a normal node, and the next storage node can be detected. For example, storage devices can continuously monitor the health status of memory, node memory capacity, and memory rate through dmidecode (a command used to retrieve hardware information); when the node memory capacity changes (that is, memory damage) or the memory rate is too low, fault alarm information will be reported and the faulty node will be controlled to enter service mode.

[0068] Furthermore, the method provided in this embodiment can also provide a memory configuration locking function to prevent unauthorized configuration changes. For example, the processor can use the dynamic memory configuration platform to receive the memory configuration adjustment instruction of the storage device; detect whether the login user corresponding to the memory configuration adjustment instruction is an authorized user; if so, adjust the predicted memory specification requirements corresponding to the storage device according to the user configuration memory specification requirements in the memory configuration adjustment instruction, and record the version information of this configuration adjustment to facilitate tracking of problems and rolling back to a stable state; if not, the process can be directly terminated or unauthorized information can be fed back.

[0069] Furthermore, the processor can also record and save alarm information (such as abnormal alarm information and fault alarm information) to facilitate subsequent analysis of the root cause of memory configuration problems and prevent similar problems that may occur in the future. For example, the processor can also determine the cause of the memory configuration alarm based on all abnormal alarm information recorded by the storage device; for example, if the storage node of a memory stick of a certain memory brand or memory model has repeatedly

[0070] In this embodiment, the embodiment of the present invention can detect abnormal nodes in a storage device that do not meet the unified memory specification requirements by checking abnormal nodes in the storage nodes according to the memory specification information and the predicted memory specification requirements corresponding to each storage node, thereby issuing corresponding alarms to standardize the memory configuration of all storage nodes in the unified storage device from the source, implement memory consistency management between storage nodes in the storage device, avoid complex problems caused by memory inconsistency, reduce the difficulty of storage system development and deployment, improve the scalability and flexibility of the system, facilitate later maintenance and upgrades, reduce operation and maintenance costs, and improve system stability.
