Description

TECHNICAL FIELD

[0001] The present application relates to the computer technology field, and in particular to a data processing method and device based on a remote storage protocol, equipment and a medium. BACKGROUND

[0002] With the rapid development of network technology, the network gradually penetrates into all aspects of people's life and work, among which, remote storage plays an important role in network technology. Remote storage is a storage method, which can access remote storage devices or services using remote terminals, so that users can store, manage and protect data.

[0003] Among them, remote storage is realized based on a remote storage protocol, and the remote storage protocol refers to an existing widely used interface specification for network remote access to non-volatile storage media (Non-Volatile Memory Express Over Fabrics, NVMe-oF). The specification defines the command format and data format for remote access to non-volatile media. Compared with the local storage protocol (Non-Volatile Memory Express, NVMe) for accessing local non-volatile media, the remote storage protocol further specifies the method of data transmission through the network.

[0004] However, since the current remote storage protocol is formulated for block device access interface, that is, the command and data format are based on the uniform linear addressing non-volatile media address space, and cannot directly provide the semantics of object storage, which leads to the fact that when the upper application calls the interface of object storage for data access, it needs to obtain the real physical address of reading and writing remote non-volatile media through complex data access address calculation and conversion of the unique object identifier and the data object itself, which may involve multiple network round trips, data serialization and deserialization operations and data copying, so that the object storage process needs to cross a complex and redundant software stack, occupies a large amount of network resources, increases the data storage overhead, and leads to low efficiency of data object access.

These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0043] ​​The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals refer to like elements, unless the context of use indicates otherwise. The following description of exemplary embodiments is not representative of all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0044] Firstly, the terms involved in the present application are explained:

[0045] Serialization: refers to the process of converting the state information of an object into a form that can be stored or transmitted.

[0046] Object storage: also known as object-based storage, is a general term used to describe a method for solving and processing discrete units, which are referred to as objects.

[0047] The data processing method based on a remote storage protocol provided by the present application aims to solve the above technical problems of the prior art.

[0048] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0049] Exemplarily, the specific application scenario of the present application can be a data transmission system as shown in Figure 1 The data transmission system can include a server and a client, wherein the server and the client are in communication connection. Optionally, the server can include but is not limited to a server, a computer, etc. Optionally, the client can include but is not limited to a personal computer, a mobile terminal, a vehicle-mounted terminal, a smart wearable device, etc. Optionally, the number of the server and the client can be one or more, which is not limited herein.

[0050] Figure 2 A data processing method based on a remote storage protocol according to an exemplary embodiment is shown, which can be applied to a client in Figure 1 , as shown in Figure 2 The data processing method based on a remote storage protocol can include:

[0051] 110, receiving a processing request, wherein the processing request is used to indicate a storage operation or a retrieval operation on the to-be-processed data.

[0052] In some embodiments, the client can receive a processing request input by a user, for example, the user can make a series of operations on the client for uploading the to-be-processed data in the client to the server for storage, and the client can generate a corresponding processing request according to the series of operations made by the user. Optionally, the series of operations can include an operation of selecting to-be-processed data, an operation of selecting to store the to-be-processed data, and the like. The processing request can be an object-based access request.

[0053] 120. serializing the processing request according to a preset remote storage protocol to obtain a serialized processing request, the serialized storage request including object storage semantics of the to-be-processed data; wherein the preset remote storage protocol is used to represent that the request for remote storage includes object storage semantics; and the object storage semantics includes a field representing a storage location of the to-be-processed data.

[0054] In some embodiments, the client can serialize the processing request to a preset remote storage protocol, that is, serialize the processing request according to the provisions of the preset remote storage protocol to obtain a serialized processing request. For example, the preset remote storage protocol extends a third field on the basis of originally only providing that the processing request needs to have a first field and a second field, and the third field needs to include object storage semantics of the to-be-processed data. When the client serializes the processing request according to the preset remote storage protocol, the serialized processing request also includes the third field, which is a field representing a storage location of the to-be-processed data. Optionally, the first field or the second field can be used to specify the format of the processing request (i.e., the access command).

[0055] 130. sending the serialized processing request to the server; wherein the serialized processing request is used to indicate the location information of the to-be-processed data obtained by parsing the object storage semantics of the to-be-processed data, and the location information of the to-be-processed data is used to execute an operation corresponding to the processing request on the to-be-processed data based on the location information of the to-be-processed data to obtain a processing result; wherein the location information of the to-be-processed data represents a physical address of the to-be-processed data; and the processing result represents whether the processing of the to-be-processed data is completed.

[0056] With the above example, the client can send the serialized processing request to the server, and the server can parse the object storage semantics of the to-be-processed data in the serialized processing request after receiving the serialized processing request, so as to obtain the location information, and then the location information extracts the to-be-processed data from the location where the to-be-processed data is stored, and then the extracted to-be-processed data is stored in the specified location of the server. When the server detects that the to-be-processed data is stored in the server, the server can generate a processing result representing that the to-be-processed data has been processed, and then feed back the processing result to the client.

[0057] 140, receiving the processing result fed back by the server and outputting the processing result.

[0058] With the above example, the client can output the processing result after receiving the processing result, to remind the user that the processing of the to-be-processed data has been completed. Optionally, the way of outputting the processing result by the client can include outputting through the display device thereof and / or outputting through the audio playing device thereof.

[0059] It can be seen that in the embodiment, the client receives a processing request, wherein the processing request is used to instruct to perform a storage operation or a taking-out operation on to-be-processed data; the processing request is serialized according to a preset remote storage protocol to obtain a serialized processing request, and the serialized storage request includes object storage semantics of the to-be-processed data. The preset remote storage protocol is used to represent that the request for remote storage includes the object storage semantics; the object storage semantics includes a field representing a location where the to-be-processed data is stored. Then, the serialized processing request is sent to the server; wherein the serialized processing request is used to instruct to obtain location information of the to-be-processed data after parsing the object storage semantics of the to-be-processed data, and the location information of the to-be-processed data is used to execute the operation corresponding to the processing request on the to-be-processed data based on the location information of the to-be-processed data, to obtain a processing result; wherein the location information of the to-be-processed data represents a physical address where the to-be-processed data is stored; the processing result represents whether the processing of the to-be-processed data is completed; and the processing result fed back by the server is received and outputted. That is, the method extends the remote storage protocol in advance, so that the remote storage protocol has the semantics of object storage. Since the semantics includes a field representing the location where the to-be-processed data is stored, the object semantics of the upper layer application is transmitted to the data transmission protocol layer while ensuring the correctness of data access. In the transmission process, only the data object stored in the location where the to-be-processed data is stored needs to be called, without copying the data, thereby reducing the additional overhead caused by data copying, and improving the data storage efficiency.

[0060] Figure 3This is a data processing method based on a remote storage protocol, as illustrated in another exemplary embodiment. This data processing method based on a remote storage protocol can be applied to... Figure 1 Clients in, such as Figure 3 As shown, the data processing method based on the remote storage protocol may include:

[0061] 210. A persistent polling forwarding process is used to receive processing requests for data to be processed. This persistent polling forwarding process receives the processing requests via polling. The processing requests instruct the processing process to perform either a storage or retrieval operation on the data to be processed.

[0062] For example, there can be multiple clients, each acting as a node in the communication network. Each client node has a resident polling forwarding process, which communicates with the application process within the client via shared memory. The application process can then issue processing requests for data to be processed. In practical applications, the application process's data object requests (i.e., the aforementioned processing requests) are sent to the server by the resident polling forwarding process.

[0063] In this embodiment, a persistent polling forwarding process receives the processing request for the data to be processed and forwards the processing request to the client. This reduces the latency of data object requests and improves application performance through polling. The number of persistent polling forwarding processes is smaller than that of application processes, which reduces the network connection to the server. At the same time, by forwarding requests, the additional overhead caused by the application process's central processing unit (CPU) polling data requests is avoided.

[0064] In some implementations, step 210 may include the following specific implementations:

[0065] 211. Receive processing requests from user processes and store the processing requests in a designated send queue in shared memory. The shared memory is shared by the user process and the resident polling forwarding process.

[0066] 212. Poll the various sending queues in shared memory through a resident polling forwarding process.

[0067] 213. If the specified sending queue is polled, the processing request is retrieved from the specified sending queue.

[0068] For example, such as Figure 4 As shown, the client can have one or more persistent polling forwarding processes (e.g., Figure 4The resident polling forwarding process is used to receive and forward the data access request of the user process, i.e., the processing request. The user process and the resident polling forwarding process communicate through a communication queue of the cross-process shared memory, i.e., the shared memory. Each user process has its own exclusive set of sending queues and receiving queues. The user process establishes communication with the forwarding process by initializing the queues when the user process is started. Alternatively, the specified sending queue can be any sending queue in the shared memory.

[0069] When the execution flow of a data access request starts from a user process, the user process calls an object storage interface to obtain a processing request and stores the processing request in a sending queue. Then, the resident polling forwarding process polls each sending queue. When a new processing request is found in a sending queue, the new processing request is pulled out for further processing. For example, the user process includes a user process 1. The user process 1 communicates with the forwarding process 0 through the cross-process shared memory. The polling device in the forwarding process 0 can poll the sending queue corresponding to the user process 1. When a new processing request is found in a sending queue, the new processing request is extracted and forwarded as an object storage command. Similarly, other user processes (e.g., a user process n) in the client can also receive and forward the processing request in the above manner. The forwarding process can also include a receiving queue, which is opposite to the sending queue. The receiving queue is used when the client needs to perform a taking-out operation on the to-be-processed data. The taking-out operation is the reverse process of the storing operation, and thus is not described herein.

[0070] In some embodiments, the shared memory includes a specified memory. The memory address of the specified memory is the memory address of the to-be-processed data.

[0071] For example, the original shared memory only includes the memory A. When the user process sends the processing request of the to-be-processed data to the shared memory, the to-be-processed data needs to be copied into the memory A. The memory allocator of the application is intercepted to allocate a specified memory in the shared memory, so that the shared memory includes the memory A1 and the specified memory B. Since the memory address of the specified memory B is the memory address of the to-be-processed data, the shared memory can directly receive the processing request of the to-be-processed data through the specified memory B without copying the to-be-processed data into the shared memory. Thus, one data copy is reduced in the processing request transmission process, and the CPU overhead is saved. As a more specific example, as shown in FIG. 2, the shared memory includes the memory A1 and the memory B. The memory address of the memory B is the memory address of the to-be-processed data. Thus, the shared memory can directly receive the processing request of the to-be-processed data through the memory B without copying the to-be-processed data into the shared memory.Figure 5 As shown, Figure 5 A processing request transmission path schematic diagram is shown, which includes a transmission path intercepting memory allocation (such as path 1 in Figure 5 ) and a transmission path without intercepting memory allocation (such as path 2 in Figure 5 ), according to Figure 5 It can be known that the processing request can be directly transmitted from the user process to the forwarding process through path 1, and in path 2, the to-be-processed data needs to be copied once and then enter the forwarding process. Therefore, the embodiment allocates specified memory in the shared memory, thereby optimizing the data transmission path, specifically reducing data copying on the critical path of data request execution, so as to reduce CPU overhead, thereby reducing the delay of request execution and improving system throughput.

[0072] 220, serializing the processing request according to a preset remote storage protocol to obtain a serialized processing request, the serialized storage request including object storage semantics of the to-be-processed data; wherein the preset remote storage protocol is used to represent that the request for remote storage includes object storage semantics; the object storage semantics include a field representing a position where the to-be-processed data is stored.

[0073] In some embodiments, the specific implementation of step 220 can include:

[0074] 221, obtaining position information, size information of the to-be-processed data, and a unique object identifier corresponding to the to-be-processed data.

[0075] 222, filling the position information, size information, and the unique object identifier corresponding to the to-be-processed data into a specified field of the processing request to obtain the serialized processing request; wherein the specified field is determined based on the preset remote storage protocol.

[0076] Following the above example, for example, when the forwarding process pulls a new processing request, the type of the processing request can be distinguished according to the type field of the processing request (such as a storage request or a retrieval request), and the unique object identifier corresponding to the to-be-processed data (hereinafter also referred to as the unique object identifier of object storage) and the position information and size information are filled into the specified field of the remote storage protocol request, which is used for the server to extract the object storage semantics.

[0077] In some embodiments, before step 220, the method can further include:

[0078] determining the byte length of the to-be-processed data; if the byte length is less than or equal to a length threshold, adding the to-be-processed data to the processing request.

[0079] Exemplarily, the client can obtain data object information of the to-be-processed data, which can include location information and byte length of the to-be-processed data. For to-be-processed data with a byte length less than a length threshold, the to-be-processed data can be directly added in the processing request and sent together through the processing request.

[0080] In some embodiments, the preset remote storage protocol supports access in a block granularity. Specifically, the protocol specifies the format of an access command, describes the size and location of to-be-processed data, and supports access in a block granularity.

[0081] 230. sending the serialized processing request to the server. The serialized processing request is used to indicate the location information of the to-be-processed data obtained after parsing the object storage semantics of the to-be-processed data, and the location information of the to-be-processed data is used to execute the operation corresponding to the processing request on the to-be-processed data based on the location information of the to-be-processed data, to obtain a processing result. The location information of the to-be-processed data represents a physical address where the to-be-processed data is stored, and the processing result represents whether the processing of the to-be-processed data is completed.

[0082] In some embodiments, the client includes a first network card, and the specific implementation of step 230 can include:

[0083] sending the serialized processing request to the server through the first network card. The shared memory is a memory accessible to the first network card.

[0084] In the above example, please refer to Figure 4 , in Figure 4 , the network card on the client side can be determined as the first network card, and the forwarding process can poll the processing request and extract the processing request. After that, the unique object identifier and the location information and the size information of the object storage can be filled into the specified field of the remote storage protocol request, which is used for the server to extract the object storage semantics to obtain the serialized processing request (hereinafter also referred to as the remote storage protocol request). Then the forwarding process encapsulates the remote storage protocol request and sends it to the server through the first network card. In Figure 4 , the network card on the server side can be used as the second network card, the first network card and the second network card can communicate, and the second network card can receive the serialized processing request sent by the first network card. The resident process of the server can poll the second network card through the poller, and when it is found that the second network card has received the serialized processing request, it can extract the unique object identifier, the location information and the size information from the specified field of the remote storage protocol request, determine the storage index of the to-be-processed data according to the unique object identifier, the location information and the size information, and obtain the physical address of the access data object on the non-volatile medium through the local storage index of the to-be-processed data. Then, the to-be-processed data is accessed through the local storage protocol and the physical address.

[0085] In some embodiments, the shared memory is set as a memory accessible by the first network card, so that the copying of the data object between the shared memory and the network stack buffer can be eliminated.

[0086] That is, in the whole process of processing request forwarding, two data copying operations of the to-be-processed data can be reduced. For example, the first data copying reduction process is that the user process needs to send the data object to the resident polling forwarding process through the inter-process shared queue, which requires one memory copying, i.e., copying the data object from the user process to the shared queue. In an embodiment, by intercepting the memory allocator of the user process, the memory address of the data object of the user is directly allocated in the shared memory, so that when the data object needs to be sent to the resident polling forwarding process, no memory copying is required, but a reference is passed, so that the resident polling forwarding process can obtain the data object through the reference, thereby reducing one data copying.

[0087] The second data copying reduction process is that when the resident polling forwarding process needs to send the data object to the server, the data object needs to be copied to the data buffer of the network stack for sending, which requires one memory copying, i.e., copying from the data object buffer of the resident process to the data buffer of the network stack. In an embodiment, by registering the data object buffer of the resident process in the data buffer of the network stack in advance, the memory copying is eliminated, i.e., when the resident process is initialized and started, a block of address space is allocated in the data buffer of the network stack, which is used for receiving and sending network requests and storing the data object of the user process. Thus, when the data object needs to be sent across the network, the data object itself does not need to be copied to the data buffer of the network stack, thereby eliminating one memory copying.

[0088] In some embodiments, in the process of accessing the to-be-processed data, it can be required that the obtained object content and the stored object content are consistent for the same object unique identifier.

[0089] In some embodiments, for the storage operation of the to-be-processed data, it can be required that the to-be-processed data is not lost after power failure, and the subsequent data reading operation can read the latest correct object content. Alternatively, the above requirement can be achieved by persisting all modification operations on the data object to the persistent medium according to the order of the operations.

[0090] In some embodiments, the access execution flow of the to-be-processed data can be implemented in a hardware device such as hardware or firmware, so that the processing request of the to-be-processed data can be more efficiently executed through the solidified hardware logic.

[0091] 240, receiving the processing result fed back by the server and outputting the processing result.

[0092] The specific implementation of step 240 can refer to step 140, and thus is not described herein.

[0093] In summary, in the data processing method based on the remote storage protocol in the embodiment, the semantics of object storage is combined into the underlying protocol of remote data transmission, so that the object storage process does not need to cross a complex and redundant software stack, and the overhead of unnecessary software levels is reduced. Specifically, the existing object storage system needs to convert the complex semantics of object storage into a specific object data storage location, and then use the underlying protocol for data read and write access. The method achieves the purpose of simplifying the software stack by supplementing and enhancing the semantics of the existing underlying protocol. The method uses widely used and mature remote data transmission protocols, adds object storage semantics to them, and can use the existing protocol stack that has been tested through engineering practice for a long time, greatly improving the reliability and robustness of the method. The method manages the life cycle of the data buffer, allowing zero-copy between the network stack and the storage stack, which not only saves valuable CPU resources, but also reduces request latency, thereby improving data access efficiency.

The preset remote storage protocol is used to indicate that the object storage semantics is included in the request for remote storage.

[0112] Serializing the processing result through the preset remote storage protocol to obtain a serialized processing result; and sending the serialized processing result to the client.

[0113] For example, the preset remote storage protocol also stipulates that the processing result needs to include a fourth field, which can represent whether the processing of the to-be-processed data is completed. By serializing the processing result through the preset remote storage protocol, the serialized processing result obtained includes the fourth field, and when the client receives the serialized processing result, it can parse the fourth field to determine whether the processing of the to-be-processed data is completed. The specific process of serializing the processing result through the preset remote storage protocol can refer to the process of serializing the processing request through the preset remote storage protocol in the above-mentioned embodiments, and will not be repeated here.

The preset remote storage protocol is used to characterize that the remote storage request includes object storage semantics; the object storage semantics include fields characterizing the location where the data to be processed is stored.

[0117] 530. The client sends the serialized processing request to the server. The serialized processing request indicates the location information of the data to be processed, obtained after parsing the object storage semantics of the data to be processed. This location information is used to execute the operation corresponding to the processing request based on the location information of the data to be processed, in order to obtain the processing result. The location information of the data to be processed represents the physical address where the data to be processed is stored; the processing result represents whether the processing of the data to be processed is complete.

[0118] 540. The server receives the serialized processing request sent by the client.

[0119] 550. The server parses the serialized processing request to obtain the location information of the data to be processed; where the location information of the data to be processed represents the physical address where the data to be processed is stored.

[0120] 560. The server executes the operation corresponding to the processing request based on the location information of the data to be processed, so as to obtain the processing result; whereby the processing result indicates whether the processing of the data to be processed is completed.

[0121] Using the example above, the server can use the physical address obtained above to call the data to be processed and perform storage or retrieval operations on the data to be processed.

[0122] 570. The server sends the processing result to the client.

[0123] 580. The client receives the processing result from the server and outputs the processing result.
