[0034] Other features and advantages of the present disclosure will become apparent from the following detailed description of exemplary embodiments of the present disclosure with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the present disclosure and, together with the description, serve to explain the principles of the present disclosure.

[0041] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions, and numerical values ​​described in these embodiments do not limit the scope of the present disclosure. The following description of at least one exemplary embodiment is merely illustrative in nature and is not intended to limit the present disclosure, its application, or uses.

[0042] Figure 1 FIG. 1 is a schematic diagram of a storage system according to an embodiment of the present disclosure. Figure 1 As shown, the storage system 100 may include one or more of a storage area network SAN 150 , a network management device 160 , and a client 170 .

[0043] The SAN 150 may include multiple network element devices. For example, the SAN 150 may include a server 151, a switch 152, and a storage device 153. The server 151 may include a physical server and / or a virtual server. The server 151 is connected to the storage device 153 via the switch 152 and can quickly access data on the storage device 153. The server 151 may also be connected to the client 170 to receive and process client data requests or execute applications. The storage device 153 may include a disk array, a tape library, or other types of storage media, and may provide high-capacity, high-performance storage capabilities to meet the needs of enterprise-level data storage. The switch may provide high-speed data transmission capabilities. For example, the switch may be a fiber optic switch or other switch that supports high-speed data transmission. The above-mentioned servers, switches, and storage devices may be one or more.

[0044] The network management device 160 can be connected to the SAN and used to manage the network element devices of the SAN. For example, the network management device 160 can perform maintenance and management functions such as data configuration management, fault management, resource management, performance management, and security management on the network element devices of the SAN. There can be one or more network management devices, and each network management device can also be called a network management system (NMS).

[0045] The client 170 can be connected to a server of the SAN, can send data requests to the server, and receive data returned by the server. There can be one or more clients.

[0046] In some embodiments, the client 170 can also connect to the network management device 160 to send instructions to the network management device or receive management data to perform corresponding maintenance and management of the SAN. In one implementation, the client connected to the network management device 160 and the client connected to the server 151 can be the same client, which can facilitate client operations. In another implementation, the client connected to the network management device 160 and the client connected to the server 151 can be different clients. In other words, the same client is not allowed to connect to both the network management device and the server. In this way, management and business operations can be separated to improve the security of the storage system.

[0047] The disclosed embodiments can be applied to the data query scenario of the storage system. In the storage system, each network element of the SAN can be configured independently, and the relevant configuration data can be stored in a dispersed manner according to the network element type. For example, the data of the SAN can be distributed in multiple data tables, for example, they can be distributed in data tables such as the server information class table, the switch service class table, and the storage information class table. The association between the data tables can be associated through the globally unique identification number of the hardware (such as the World Wide Name, WWN). In order to query the data of the SAN, multiple steps can be performed according to the association between them, and queries and integration can be performed from multiple dispersedly stored data tables. Since multiple steps are required for the query, the query efficiency is low and the response speed is slow, which affects the user experience and operation and maintenance efficiency.

[0048] Figure 2 FIG. 1 is a flow chart of a data query method provided by an embodiment of the present disclosure. The method can be executed by the network management device in the above storage system. Figure 2 As shown, the data query method of this embodiment may include one or more of the following steps S210 to S230.

[0049] Step S210: receiving a query instruction for querying storage area network (SAN) data.

[0050] The SAN includes multiple network element devices, which include at least one server, at least one fiber optic switch and at least one storage device.

[0051] In some embodiments, the query instruction can be an instruction sent by the client to the network management device. For example, when the client needs to query SAN data based on user operations or scheduled tasks, the client can send the query instruction to the network management device, and the network management device can receive the query instruction.

[0052] In other embodiments, the network management device may receive the query command input by the user via an input component. The input component may include at least one of a keyboard, a mouse, a camera, and a microphone. For example, the network management device may receive the query command input by the user via a keyboard and / or a mouse. In another example, the network management device may capture user gestures via a camera and determine the query command based on the gestures. In another example, the network management device may capture user voice information via a microphone and determine the query command based on the voice information. This improves user convenience.

[0053] Step S220 : acquiring target data entries corresponding to the query instruction from a first data set stored in a first memory according to the query parameters in the query instruction.

[0054] In some embodiments, the first memory storing the first data set may be a volatile memory. For example, the first memory may be a volatile memory that supports fast read and write operations, such as a random access memory (RAM) or cache memory. Thus, by storing the first data set in a volatile memory that supports fast read and write operations, data query efficiency can be improved and data query response time can be reduced. Alternatively, the first data set may be a data structure stored in the RAM memory of the network management device.

[0055] In some embodiments, the first data set may include multiple candidate data entries, which may be obtained by encoding original data entries of the network element device based on a preset encoding format, and different candidate data entries may contain data of the same or different network element devices.

[0056] In one implementation, the multiple candidate data entries in the first data set may include the original data entries of all network element devices of the SAN. For example, the configuration data, performance data, maintenance data, etc. of all network element devices of the SAN can all be used as data content in the candidate data entries in the first data set, that is, the data content in each candidate data entry can be specific information of a network element device corresponding to the SAN, and the specific information can be configuration parameters in the configuration data, performance indicators in the performance data, or maintenance information in the maintenance data, etc.

[0057] In one implementation, to achieve network element device association, each candidate data entry may further include a filtering keyword. Using the filtering keyword and query parameters, the target data entry corresponding to the query instruction can be filtered from the first data set. The filtering keyword may include the device identifier of the first network element device (e.g., a server, switch, or storage device) to which the data entry corresponds, as well as the device identifiers of other network element devices associated with the first network element device.

[0058] Furthermore, the filtering keyword may also include a filtering identifier obtained by encoding all or part of the original data entry, such as the configuration time of the original data entry, the geographical location of the network element device, hardware configuration, storage capacity, link identifier, service identifier, etc.

[0059] Optionally, the above-mentioned query instruction may include query parameters, which may include at least one of parameters such as device identification, time range, geographical range, storage capacity range, etc. The query parameters can be used to filter and screen multiple candidate data entries in the first data set to obtain one or more target data entries.

[0060] In some embodiments, the above-mentioned preset coding format can be used to characterize that the content of each candidate data entry includes a filter keyword and data content, and the data content may include the content in the original data entry, such as the configuration information of the server, the configuration information of the switch, or the configuration information of the storage device; the filter keyword can be used to filter the target data entry that matches the query from the first data set. Furthermore, the preset coding format can also be used to characterize the content and coding form included in the filter keyword. For example, the preset coding format can characterize that the filter keyword includes one or more network element device identifiers, and each network element device identifier can occupy N bits, where N is a pre-set positive integer. The number of bits occupied by the filter keyword can be determined based on the maximum number of network element devices in the SAN. Through this preset coding format, the integrity and comprehensiveness of the data can be ensured, and a basis for efficient query is provided.

[0061] In some embodiments, an implementation of step S220 may include encoding the query parameter according to a preset encoding format to obtain filter code information, filtering the first data set according to the filter code information, and selecting one or more candidate data entries containing the filter code information as target data entries. For example, one or more candidate data entries containing the filter code information in the filtering keyword may be selected as target data entries.

[0062] In this way, target data items can be obtained by filtering the first data set based on the query parameters, thereby improving data query efficiency.

[0063] Step S230: Send the target data entry to the target device.

[0064] The target device includes a device for displaying target data items and / or a device for sending query instructions.

[0065] In some embodiments, if the above-mentioned query instruction is an instruction sent by the client to the network management device, the target device may be the client that sends the query instruction, and the network management device may send the target data entry to the client so that the client can display the target data entry to the user as needed.

[0066] In other embodiments, if the query command is input by a user via an input component of a network management device, the target device may include a device for displaying the target data item, such as a display screen of the network management device. In this way, the network management device can display the retrieved target data item to the user via the display screen. Furthermore, the network management device can also play relevant information related to the retrieved target data item, such as the number of retrieved target data items, to the user via an audio output device such as a speaker.

[0067] Thus, using Figure 2 The method shown, based on the first data set pre-generated and stored in the first memory, can quickly query and obtain the target data entries corresponding to the query instructions. In typical scenarios (for example, a network scale of 500,000 optical fiber ports), the query results can be fed back in seconds. Compared with the query result feedback in minutes in related technologies, the data query efficiency has been greatly improved, and the user's query operations can be responded to quickly, thereby improving the user experience and operation and maintenance efficiency.

[0068] Figure 3 This is a flow chart of a method for generating a first data set provided by an embodiment of the present disclosure. The method can be executed by the network management device in the above storage system, for example, the method can be executed in Figure 2 The data query method shown is executed before to pre-generate the first data set. Figure 3 As shown, the method for generating the first data set in this embodiment may include one or more of the following steps S310 to S340.

[0069] Step S310: collecting original data entries of multiple network element devices of the SAN.

[0070] In some embodiments, the original data entry may be distributedly stored data, for example, distributedly stored on various network element devices, with each network element device only storing its own original data entry.

[0071] In some embodiments, the original data entry may include configuration information of the network element device. In this way, the configuration information of each network element device of the SAN can be obtained, and the candidate data entries in the first data set can be generated based on the configuration information.

[0072] Step S320 : Encode the original data entries of the plurality of network element devices based on a preset encoding format to obtain a plurality of candidate data entries.

[0073] In some embodiments, for each original data entry, the filtering keyword corresponding to the original data entry can be determined based on the first network element device corresponding to the original data entry and other network element devices associated with the first network element device; and a candidate data entry can be generated based on the original data entry and the filtering keyword corresponding to the original data entry.

[0074] It should be noted that the first network element device corresponding to the original data entry may be the network element device configured by the original data entry, that is, the network element device that generated the original data entry. For example, if an original data entry contains configuration information of a server and is also generated by the configuration of the server, the first network element device corresponding to the original data entry may be the first server.

[0075] The candidate data entries generated in the above manner include filtering keywords and data content. The data content may be the original data entry, and the filtering keywords may include the device identifier of the first network element device corresponding to the original data entry, as well as the device identifiers of other network element devices associated with the first network element device. The device identifiers of the network element devices may be uniformly numbered. In one or more SANs connected to the network management device, different network element devices correspond to different device identifiers, and any network element device can be identified based on the device identifier. For example, if a SAN includes two servers, the device identifiers of the two servers may be different.

[0076] Furthermore, the filtering keyword may also include a filtering identifier obtained by encoding all or part of the content of the original data entry, such as the configuration time of the original data entry, the geographical location of the network element device, the hardware configuration, the storage capacity, the link identifier, the service identifier, etc. For example, if the original data entry includes the storage capacity of a storage device, the storage capacity may be encoded to obtain a storage capacity identifier. The filtering keyword may include the device identifier and the storage capacity identifier. In this way, SAN data may be queried based on storage capacity. For example, relevant configuration data of all storage devices with storage capacity greater than or equal to a specific value, as well as relevant configuration data of switches and servers associated with (e.g., connected to) the storage device, may be queried.

[0077] Step S330: Store the plurality of candidate data entries in a first memory to generate a first data set.

[0078] The first memory may be a volatile memory, and the first data set may be a data structure stored in the volatile memory, for example, a data structure stored in the form of a database or a data list.

[0079] Step S340: Store the plurality of candidate data entries in a second memory to obtain a second data set.

[0080] The second memory is a non-volatile memory, which may include a disk array, etc. For example, the second memory may be a disk array of a network management device, and the first memory may be a RAM of the network management device.

[0081] In some embodiments, the second memory may be multiple. For example, the second data set may be stored in a primary memory and a backup memory. Both the primary memory and the backup memory may be non-volatile memories. The second data set in the primary memory is used first. If the primary memory fails, the second data set in the backup memory is used. This allows for backup of the second data set and improves data reliability. Furthermore, the second data set may be stored on a cloud server to further improve data reliability.

[0082] It should be noted that the above steps S330 and S340 can be executed in parallel or sequentially, and the order is not limited. For example, step S330 can be executed first, and then when step S340 is executed, the first data set stored in the first memory can be copied or transferred to the second memory to obtain the second data set. For another example, step S340 can be executed first, and then when step S330 is executed, the second data set stored in the second memory can be copied or transferred to the first memory to obtain the first data set.

[0083] Thus, using Figure 3 The method shown can generate a first data set based on original data entries of multiple network element devices and store it in a first memory, so as to quickly query target data entries based on the first data set, thereby improving query efficiency.

[0084] In some embodiments, the first data set and the second data set may be synchronized based on an event or periodic manner.

[0085] For example, synchronization of the first data set and the second data set may be achieved by at least one of the following methods:

[0086] Method 1: When the configuration data of the network element device is changed, the second data set is updated according to the changed configuration data, and the candidate data entries of the updated second data set are synchronized to the first data set.

[0087] Optionally, based on this first method, the candidate data entries that have changed in the second data set can be determined based on the configuration data of the network element device that has changed, and only the candidate data entries that have changed in the second data set can be synchronized to the first data set. In this way, full data synchronization is not required, which can improve the efficiency of data synchronization. The candidate data entries can be synchronized by copying and replacing. For example, the candidate data entries that have changed in the second data set can be copied to the first data set and replace the corresponding candidate data entries; for another example, all the candidate data entries in the second data set can be copied to the first data set and replace all the candidate data entries in the first data set.

[0088] Method 2: When the current time is a preset scheduled synchronization time, the candidate data entries of the second data set are synchronized to the first data set.

[0089] The current time is the current time of the network management device, and the pre-set scheduled synchronization time may be a user-set or system-default scheduled synchronization time, such as a specific time of each hour, each day, each week, or each month. For example, if the scheduled synchronization time is 3:00 a.m. every day, when the current time of the network management device is 3:00 a.m., scheduled synchronization may be performed to synchronize the candidate data entries of the second data set to the first data set.

[0090] In one implementation, based on the second approach, full data synchronization may be performed to synchronize all candidate data entries in the second data set to the first data set, so as to ensure the accuracy of the first data set.

[0091] In another implementation, the candidate data entries in the second data set and the first data set may be compared to determine whether they are identical. For different candidate data entries, the candidate data entries in the second data set may be updated to the first data set. This may improve the efficiency of data synchronization.

[0092] In the second approach, the specific approach of synchronizing the candidate data entries of the second data set to the first data set may also include at least one of the following implementations:

[0093] In one implementation, if the configuration data of the network element device is in a steady state, the candidate data entries of the second data set are synchronized to the first data set; the steady state can be used to indicate that the configuration data of the network element device is not in the process of being changed.

[0094] In another implementation, if the configuration data of a network element device is in a non-stable state, the system waits until the configuration data of the network element device enters a stable state, then updates the second data set based on the stable configuration data, and synchronizes the candidate data entries of the updated second data set with the first data set. This prevents data anomalies in the synchronized first data set caused by the non-stable configuration data. Furthermore, while waiting for the configuration data of the network element device to enter a stable state, the network device can be prohibited from executing new configuration data changes. In this way, the network element device only needs to complete the currently executing configuration data change before entering a stable state, reducing the waiting time for data synchronization.

[0095] In another implementation, when the current time is a pre-set scheduled synchronization time, the network element device may be prohibited from executing new configuration data changes. After determining that the configuration data of the network element device is in a steady state, the second data set is updated according to the configuration data of the network element device, and the candidate data entries of the updated second data set are synchronized to the first data set. After completing the synchronization of the first data set, the network element device is allowed to execute new configuration data changes.

[0096] For example, the network management device may implement timed data synchronization based on the following steps:

[0097] First, when the current time is a preset scheduled synchronization time, the network management device sends a data synchronization indication message to each network element device of the SAN.

[0098] This data synchronization indication message can be used to instruct a network element device to prohibit executing new configuration data changes. After receiving this data synchronization indication message, each network element device can send a data synchronization response message to the network management device after its configuration data is in a steady state or after completing a current configuration data change and entering a steady state. Furthermore, after receiving this data synchronization indication message, the network element device can prohibit executing new configuration data changes.

[0099] Secondly, after receiving the data synchronization response messages sent by all network element devices, the network management device updates the second data set according to the configuration data of each network element device, and synchronizes the candidate data entries of the updated second data set to the first data set.

[0100] Finally, after completing the synchronization of the first data set, the network management device sends a data synchronization completion message to each network element device of the SAN.

[0101] The data synchronization completion message can be used to indicate that the network element device can execute the new configuration data change. In this way, the network element device can start executing the new configuration data change after receiving the data synchronization completion message.

[0102] In this way, it is possible to avoid the configuration data being in an unsteady state during the scheduled synchronization, which may result in abnormal data in the synchronized first data set, thereby improving the accuracy of the first data set.

[0103] In some embodiments, after receiving a data synchronization indication message, the network element device prohibits executing new configuration data changes. Instead, the network element device can cache received configuration data change commands in chronological order. Upon receiving a data synchronization completion message, the network element device can execute the cached configuration data change commands in chronological order. This can avoid the problem of configuration data change command execution failure during scheduled synchronization.

[0104] In other embodiments, after receiving a data synchronization indication message and sending a data synchronization response message, the network element device may start a timer. If the timer reaches a preset time duration and still does not receive a data synchronization completion message, the execution of new configuration data changes may no longer be prohibited. The preset time duration may be any pre-configured time duration, such as 1 minute, 5 minutes, or 10 minutes.

[0105] This can avoid the problem of configuration data changes being unable to execute for a long time, especially when the data synchronization completion message is lost, and can improve the reliability of the SAN configuration.

[0106] Figure 4 This is a structural diagram of a data query device provided by an embodiment of the present disclosure. Figure 4 As shown, the device may include:

[0107] The receiving module 401 is configured to receive a query instruction for querying data of a storage area network (SAN); wherein the SAN includes a plurality of network element devices, including servers, fiber switches, and storage devices;
