Description

Technical Field

[0001] This application relates to the field of storage technology, and in particular to a request parameter configuration method, apparatus, device, storage medium, and program product. Background Technology

[0002] NVMe over RoCE (NVMe over RDMA via Converged Ethernet) storage systems include a target device and multiple initiators. The initiators can write data to the target device via immediate write requests. An immediate write request is a write request that arrives at the target device along with a request command word. Therefore, it can reduce one process of reading data from remote memory, thereby reducing the processing latency of write requests and improving CPU utilization.

[0003] In related technologies, during the connection establishment process between the target and the initiator, the target can pre-configure the granularity of immediate write requests. However, it generally only supports configuring immediate write requests with a single granularity. This method requires the initiator to write a fixed amount of data each time through an immediate write request, which cannot meet diverse application needs when the application requests of the initiator change. Summary of the Invention

[0004] Therefore, it is necessary to provide a method, apparatus, device, storage medium, and program product capable of adaptively adjusting request parameter configuration to address the aforementioned technical problems.

[0005] In a first aspect, this application provides a request parameter configuration method for a target in a storage system, the storage system including a target and multiple initiators, the method comprising:

[0006] Get multiple immediate write requests sent by the target initiator within the target time period, where the target initiator is any one of the multiple initiators;

[0007] Based on the multiple immediate write requests sent by the target initiator, determine the write request data volume information of the target initiator;

[0008] Configure the immediate granularity for the target initiator based on the write request data volume information of the target initiator. The immediate granularity is used to indicate the maximum allowed data volume of a single immediate write request sent by the target initiator.

[0009] In the above embodiments, the target in the storage system includes a target and multiple initiators. First, multiple immediate write requests sent by the target initiator within a target time period are acquired, where the target initiator is any one of the multiple initiators. Then, based on the acquired multiple immediate write requests sent by the target initiator, the write request data volume information of the target initiator is determined. Finally, based on the write request data volume information of the target initiator, the target initiator is configured with an immediate granularity indicating the maximum allowed data volume of a single immediate write request sent by the target initiator. In this way, the target can configure the immediate granularity of the target initiator according to the write request data volume information of the target initiator. When the write request data volume of the target initiator changes, the configuration can be adaptively adjusted, thereby meeting the diverse application needs of the target initiator and improving the flexibility of immediate write request operations.

[0010] In one embodiment, acquiring multiple immediate write requests sent by the target initiator within the target time period includes:

[0011] Get the application requests sent by each launcher within the target time period. The application requests carry the request type and launcher identifier.

[0012] Based on the request type and initiator identifier carried in the received application requests, multiple immediate write requests sent by the target initiator are filtered out from the received application requests.

[0013] In the above embodiments, the target device filters out multiple application requests received within the target time period to obtain multiple immediate write requests sent by the target initiator, thereby configuring the parameters of the immediate write requests of the target initiator according to the multiple immediate write requests.

[0014] In one embodiment, the write request data volume information of the target initiator is determined based on the multiple immediate write requests sent by the target initiator, including:

[0015] Based on each immediate write request sent by the target initiator, determine the reference immediate granularity corresponding to each immediate write request. The reference immediate granularity is used to characterize the maximum allowed data volume of the corresponding immediate write request.

[0016] The reference immediate value granularity corresponding to each immediate write request is used as the write request data volume information of the target initiator.

[0017] In the above embodiments, the corresponding reference immediate granularity is determined based on each immediate write request of the target initiator, thereby determining the write request data volume information of the target initiator, providing a data basis for adaptively adjusting the immediate granularity of the target initiator according to the write request data volume information.

[0018] In one embodiment, configuring the immediate granularity of the target initiator based on the write request data volume information of the target initiator includes:

[0019] Configure the immediate granularity for the target initiator based on the reference immediate granularity with the largest proportion among the reference immediate granularities corresponding to multiple immediate write requests.

[0020] In the above embodiments, the corresponding reference immediate granularity is determined according to each immediate write request of the target initiator, and the reference immediate granularity with the largest proportion is configured as the immediate granularity of the target initiator. In this way, the immediate write requests of most target initiators can be satisfied, avoiding the situation where many immediate write requests cannot be fulfilled if the immediate granularity is set too small, or the memory resources are wasted if the immediate granularity is set too large, thereby improving the utilization rate of memory resources.

[0021] In one embodiment, the method further includes:

[0022] Determine the number of write requests in the application request based on the request type carried by the received application request;

[0023] Based on the number of write requests and the number of application requests, the immediate connection quota information is determined. The immediate connection quota information is used to characterize the maximum number of initiators that the target can connect to.

[0024] In the above embodiments, by adaptively adjusting the immediate connection quota supported by the target device by obtaining immediate connection requests within the sampling period, and increasing or decreasing the immediate connection quota, the waste of memory resources caused by invalid immediate connections can be reduced.

[0025] In one embodiment, after configuring the immediate granularity of the target initiator based on the write request data volume information of the target initiator, the method further includes:

[0026] If the immediate granularity of the target initiator is updated, the target's memory resource configuration is adjusted. The memory resource configuration is used to configure the size of the memory resource pool corresponding to different immediate granularities.

[0027] In the above embodiments, multiple initiators can share a memory resource pool. By adjusting the size of the shared memory resource pool, various immediate value granularities can share memory resources, thereby supporting multiple initiators and multiple immediate value connections, leveraging the performance advantages of immediate value writing in different application scenarios, and effectively improving the utilization rate of memory resources.

[0028] In one embodiment, adjusting the target's memory resource configuration according to the immediate granularity configured for the target initiator includes:

[0029] If the free resources of the memory resource pool corresponding to the target immediate granularity are greater than the preset free resource threshold, the capacity of the memory resource pool corresponding to the target immediate granularity is reduced; the target immediate granularity can be any one of multiple immediate granularities.

[0030] If the idle resources of the memory resource pool corresponding to the target immediate value granularity are less than the preset idle resource threshold, the capacity of the memory resource pool corresponding to the target immediate value granularity is increased.

[0031] In the above embodiments, the shared memory resource pool corresponding to each immediate granularity is expanded or shrunk by setting a preset idle resource threshold, so as to avoid the waste of memory resources and effectively improve the utilization rate of memory resources.

[0032] In one embodiment, the method further includes:

[0033] Obtain the connection request sent by the target initiator and obtain the immediate connection quota information;

[0034] If the number of initiators currently connected to the target is less than the immediate connection quota, parse the connection request and determine the initiator identifier of the connection request;

[0035] Based on the initiator identifier in the connection request, obtain the immediate granularity of the target initiator configuration;

[0036] The target initiator is initialized and configured according to the immediate granularity of the target initiator configuration.

[0037] In the above embodiments, after receiving the connection request from the target initiator, the target initiator is initialized by querying its configuration, so that the target initiator can perform immediate write operations according to the configured immediate granularity.

[0038] Secondly, this application also provides a request parameter configuration apparatus for use in a target in a storage system, the storage system including a target and a plurality of initiators, the apparatus comprising:

[0039] The acquisition module is used to acquire multiple immediate write requests sent by the target initiator within the target time period. The target initiator can be any one of the multiple initiators.

[0040] The determination module is used to determine the write request data volume information of the target initiator based on the multiple immediate write requests sent by the target initiator.

[0041] The configuration module is used to configure the immediate granularity for the target initiator based on the write request data volume information of the target initiator. The immediate granularity is used to indicate the maximum allowed data volume of a single immediate write request sent by the target initiator.

[0042] Thirdly, this application also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the request parameter configuration method described in any of the first aspects above.

[0043] Fourthly, this application also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the request parameter configuration method described in any of the first aspects above.

[0044] Fifthly, this application also provides a computer program product, including a computer program that, when executed by a processor, implements the request parameter configuration method described in any of the first aspects above.

[0045] The aforementioned request parameter configuration method, apparatus, device, storage medium, and program product are used in a target device within a storage system. The storage system includes a target device and multiple initiators. First, multiple immediate write requests sent by the target initiator within a target time period are acquired, where the target initiator is any one of the multiple initiators. Then, based on the acquired multiple immediate write requests sent by the target initiator, the write request data volume information of the target initiator is determined. Finally, based on the write request data volume information of the target initiator, an immediate granularity is configured for the target initiator to indicate the maximum allowed data volume of a single immediate write request sent by the target initiator. In this way, the target device can configure the immediate granularity for the target initiator based on the write request data volume information of the target initiator. When the write request data volume of the target initiator changes, the configuration can be adaptively adjusted, thereby meeting the diverse application needs of the target initiator and improving the flexibility of immediate write request operations.

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0061] The request parameter configuration method provided in this application embodiment can be applied to, for example, Figure 1The application environment shown is illustrated. The storage system includes a target 102 and multiple initiators 104. The target 102 communicates with the initiators 104 via a network. The initiators 104 can be, but are not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, and projection devices. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted displays. Head-mounted displays can be virtual reality (VR) devices, augmented reality (AR) devices, and smart glasses. The target 102 is the storage array endpoint and can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0062] In one exemplary embodiment, such as Figure 2 As shown, a request parameter configuration method is provided, which can be applied to... Figure 1 Taking the target in the example, the explanation includes the following steps 201 to 203. Wherein:

[0063] Step 201: Obtain multiple immediate write requests sent by the target initiator within the target time period.

[0064] In this context, the target initiator can be any one of multiple initiators. The target is the storage end, the initiator is the client that wants to access the storage end, and the immediate write request is a write request in which the initiator sends a request command word along with data to the target. The target time period can be a sampling time period set by the user. By sampling the immediate write requests of the target initiator within the target time period, i.e., the sampling period, the information of the immediate write requests of the target initiator can be obtained.

[0065] Optionally, the target can filter among the multiple application requests received from multiple initiators using the identification information of each initiator, thereby obtaining the immediate write request sent by the target initiator within the target time period.

[0066] Step 202: Determine the write request data volume information of the target initiator based on the multiple immediate write requests sent by the target initiator.

[0067] The write request data size information can be used to characterize the size of the data corresponding to multiple immediate write requests on the target launcher. The data size of different immediate write requests may be different. For example, the data size of immediate write requests sent by different applications on the target launcher may be 4KB, 8KB, or 16KB, etc. Here, 4KB, 8KB, or 16KB refers to the amount of data that an immediate write request can carry.

[0068] Step 203: Configure the immediate granularity for the target initiator based on the write request data volume information of the target initiator.

[0069] The immediate granularity indicates the maximum allowed data size for a single immediate write request sent by the target initiator. Optionally, the appropriate immediate granularity of the target initiator can be determined based on the distribution of write request data sizes among multiple immediate write requests sent by the target initiator within the target time period. For example, if the target initiator sends a large number of immediate write requests with a data size of 8KB, the immediate granularity of the target initiator can be set to 8KB. Alternatively, if the data size of multiple immediate write requests sent by the target initiator is less than 16KB, the immediate granularity of the target initiator can be set to 16KB, which can satisfy the needs of all immediate write requests.

[0070] In the above embodiments, the target in the storage system includes a target and multiple initiators. First, multiple immediate write requests sent by the target initiator within a target time period are acquired, where the target initiator is any one of the multiple initiators. Then, based on the acquired multiple immediate write requests sent by the target initiator, the write request data volume information of the target initiator is determined. Finally, based on the write request data volume information of the target initiator, the target initiator is configured with an immediate granularity indicating the maximum allowed data volume of a single immediate write request sent by the target initiator. In this way, the target can configure the immediate granularity of the target initiator according to the write request data volume information of the target initiator. When the write request data volume of the target initiator changes, the configuration can be adaptively adjusted, thereby meeting the diverse application needs of the target initiator and improving the flexibility of immediate write request operations.

[0071] In the embodiments of this application, step 201 is as follows: Figure 3 As shown, it may include:

[0072] Step 301: Obtain the application requests sent by each launcher within the target time period.

[0073] The application request carries the request type and the initiator identifier. Optionally, the request type of the application request sent by the initiator can include read requests and write requests, and the initiator identifier can be the name information of the initiator, which is unique. The target receives the application requests sent by each initiator in the target time period and counts the received application requests to obtain the total number of application requests.

[0074] Step 302: Based on the request type and initiator identifier carried by the received application request, filter out multiple immediate write requests sent by the target initiator from the received application requests.

[0075] Specifically, based on the request type and initiator identifier, application requests are matched to identify those that are write requests and whose initiator identifier matches that of the target initiator. These are the immediate write requests sent by the target initiator. In essence, the target initiator can filter out multiple immediate write requests corresponding to each initiator using the request type and initiator identifier, and then configure the appropriate immediate granularity for each initiator based on these requests.

[0076] In the above embodiments, the target device filters out multiple application requests received within the target time period to obtain multiple immediate write requests sent by the target initiator, thereby configuring the parameters of the immediate write requests of the target initiator according to the multiple immediate write requests.

[0077] In one embodiment, step 202 above, which determines the write request data volume information of the target initiator, is as follows: Figure 4 As shown, it includes:

[0078] Step 401: Determine the reference immediate granularity corresponding to each immediate write request based on each immediate write request sent by the target initiator.

[0079] The reference immediate granularity is used to characterize the maximum allowed data size for the corresponding immediate write request. The immediate write request carries data size information, and the reference immediate granularity for each immediate write request can be determined based on this information. For example, if the data size of an immediate write request is 4KB, then the reference immediate granularity for that immediate write request is 4KB.

[0080] Step 402: Use the reference immediate granularity corresponding to each immediate write request as the write request data volume information of the target initiator.

[0081] Optionally, the set of reference immediate granularities corresponding to each immediate write request, that is, the set of reference immediate granularities corresponding to all immediate write requests sent by the target initiator, can be used as the write request data volume information of the target initiator. For example, when six immediate write requests are received from the target initiator, and the reference immediate granularities corresponding to the six immediate write requests are 4KB, 4KB, 8KB, 16KB, 32KB, and 4KB respectively, the set of the above reference immediate granularities can be used as the write data volume request information of the target initiator.

[0082] Optionally, after determining the write request data volume information of the target initiator, step 203 above, which configures the immediate granularity of the target initiator based on the write request data volume information, includes:

[0083] Configure the immediate granularity for the target initiator based on the reference immediate granularity with the largest proportion among the reference immediate granularities corresponding to multiple immediate write requests.

[0084] Optionally, the reference immediate granularity in the write request data volume information can include 4KB, 8KB, 16KB, or 32KB. A count value is set for each reference immediate granularity. The count is performed based on the reference immediate granularity corresponding to each immediate write request. For example, if the reference immediate granularity for an immediate write request is 4KB, the count value for 4KB is incremented by 1. This process is repeated for all immediate write requests to obtain the count value for each reference immediate granularity. Based on the count values ​​for each reference immediate granularity, the reference immediate granularity with the highest percentage can be determined and used as the immediate granularity for the target initiator. Taking the six reference immediate granularities in the write request data volume as an example, the percentage of reference immediate granularities with a 4KB granularity is 50%, while the percentages of reference immediate granularities with 8KB, 16KB, and 32KB are approximately 16.7%. Therefore, 4KB can be configured as the immediate granularity for the target initiator, which can meet the needs of most immediate write requests while avoiding excessively large immediate granularity settings that would waste memory resources.

[0085] In the above embodiments, the corresponding reference immediate granularity is determined according to each immediate write request of the target initiator, and the reference immediate granularity with the largest proportion is configured as the immediate granularity of the target initiator. In this way, the immediate write requests of most target initiators can be satisfied, avoiding the situation where many immediate write requests cannot be fulfilled if the immediate granularity is set too small, or the memory resources are wasted if the immediate granularity is set too large, thereby improving the utilization rate of memory resources.

[0086] In the embodiments of this application, the immediate granularity configuration process of the target initiator described above can be as follows: Figure 5As shown. Optionally, the immediate write request of the target initiator is obtained, and then the immediate granularity configuration of the target initiator is checked. If it does not exist, it means that the target initiator was not configured before and does not support immediate write requests, so the process ends. If it exists, the immediate write requests of the target initiator are counted, and then the reference immediate granularity of the immediate write request is obtained. Optionally, in this embodiment, the immediate value is represented by a power of 2 of 4KB, that is, the power levels (0, 1, 2, 3) correspond to (4KB, 8KB, 16KB, 32KB) respectively. Therefore, the 4KB granularity power level corresponding to the reference immediate granularity of the immediate write request is calculated, and the count value of the corresponding 4KB granularity power level is incremented by 1. It is then determined whether the current sampling period has ended. If the sampling period has not ended, the immediate write request processing is completed and the process ends. The judgment continues when the next immediate write request of the target initiator is obtained. If the sampling period has ended, the proportion of all power levels of the target initiator within the sampling period is calculated, and the power level with the highest proportion is used as the immediate granularity power level of the newly connected initiator for configuration. After configuration, reset the target launcher's granular power-level statistical parameters, such as clearing all count values ​​to zero.

[0087] Optionally, the immediate join quota information of the target device can also be determined based on the immediate write request, such as... Figure 6 As shown, the steps also include:

[0088] Step 601: Determine the number of write requests in the application request based on the request type carried by the received application request.

[0089] Optionally, a write request count can be set, initially set to 0. The count is incremented by 1 if the request type is a write request. After evaluating all application requests, the total number of write requests is determined from the write request count.

[0090] Step 602: Determine the immediate connection quota information based on the number of write requests and the number of application requests.

[0091] The immediate connection quota information is used to characterize the maximum number of initiators that the target can connect to. Optionally, the write request ratio can be obtained based on the number of write requests and the number of application requests. The write request floating level of the target can be determined based on the write request floating level, and the immediate connection quota information of the target can be adjusted based on the write request floating level.

[0092] For example, such as Figure 7The diagram shows a flowchart for configuring the immediate connection quota information of the target device. The global immediate connection quota is adjusted based on the proportion of immediate write requests within the sampling period. Upon receiving an application request, the number of application requests is counted, and the request type is parsed. If it is not a write request, the process ends. If it is a write request, and the write request size exceeds the preset immediate granularity, the current decision ends. If the write request size is within the preset immediate granularity range, the immediate write requests are counted. For example, every 10 percentage point fluctuation in the immediate write request proportion corresponds to one level. If the fluctuation level changes within the current sampling period, the global immediate connection quota is increased or decreased.

[0093] In the above embodiments, by adaptively adjusting the immediate connection quota supported by the target device by obtaining immediate connection requests within the sampling period, and increasing or decreasing the immediate connection quota, the waste of memory resources caused by invalid immediate connections can be reduced.

[0094] In one embodiment, the target can maintain a shared memory resource pool for each preset immediate granularity. To improve the utilization of each shared memory resource pool, the pool can be adjusted according to changes in the immediate granularity configured for each initiator. This includes:

[0095] If the immediate granularity of the target initiator is updated, the target's memory resource configuration is adjusted. The memory resource configuration is used to configure the size of the memory resource pool corresponding to different immediate granularities.

[0096] Different immediate value granularities correspond to different shared memory resource pools. For example, an immediate value granularity of 4KB corresponds to shared memory resource pool A, and an immediate value granularity of 8KB corresponds to shared memory resource pool B. The request receive queue for immediate write requests with an immediate value granularity of 4KB uses shared memory resource pool A, and the request receive queue for immediate write requests with an immediate value granularity of 8KB uses shared memory resource pool B. When the immediate value granularity configured in the target launcher is updated, for example, if the immediate value granularity is adjusted from 4KB to 8KB, it can be determined whether the 4KB shared memory resource pool A and the 8KB shared memory resource pool B need to be resized. Optionally, the adjustment methods include the following two:

[0097] In the first approach, if the idle resources of the memory resource pool corresponding to the target immediate granularity are greater than a preset idle resource threshold, the capacity of the memory resource pool corresponding to the target immediate granularity is reduced; the target immediate granularity can be any one of multiple immediate granularities.

[0098] Optionally, the idle resources of the memory resource pool, i.e. unused memory resources, can be set according to actual usage needs. When the idle resources exceed the preset idle resource threshold, it means that there are many idle resources in the memory resource pool and the utilization rate of the memory resource pool is low. Therefore, the capacity of the memory resource pool can be reduced. Optionally, the reduced capacity can be determined according to the preset idle resource threshold. For example, the memory resource pool can be reduced until the idle resources are equal to the preset idle resource threshold.

[0099] The second approach involves expanding the capacity of the memory resource pool corresponding to the target immediate value if the available resources are less than a preset free resource threshold.

[0100] Optionally, when the free resources in the memory resource pool are less than the preset free resource threshold, it indicates that the free resources in the memory resource pool are relatively small, the utilization rate of the memory resource pool is relatively high, and the memory capacity may be insufficient. Therefore, the memory resource pool can be expanded. Optionally, the expanded capacity can be determined according to the preset free resource threshold. For example, the memory resource pool can be expanded until the free resources are equal to the preset free resource threshold.

[0101] In the above embodiments, multiple launchers can share a memory resource pool. By adjusting the size of the shared memory resource pool, various immediate value granularities can share memory resources, thereby supporting multi-launcher, multi-immediate value connections. This leverages the performance advantages of immediate value writing in different application scenarios and effectively improves memory resource utilization. Simultaneously, by setting a preset idle resource threshold, the shared memory resource pool corresponding to each immediate value granularity can be expanded or shrunk to avoid wasting memory resources and effectively improve memory resource utilization.

[0102] In one embodiment, after the above request parameters are configured, as follows: Figure 8 As shown, the method also includes:

[0103] Step 801: Obtain the connection request and immediate connection quota information sent by the target initiator.

[0104] Upon receiving a connection request from the target initiator, obtain the immediate connection quota information configured in the target initiator. Based on the immediate connection quota information and the number of initiators currently connected, determine whether to support the target initiator's connection request.

[0105] Step 802: If the number of initiators currently connected to the target is less than the immediate connection quota information, parse the connection request and determine the initiator identifier of the connection request.

[0106] If the number of initiators currently connected to the target is less than the immediate connection quota, then the connection request of the target initiator is parsed to obtain the initiator identification information carried in the connection request.

[0107] Step 803: Obtain the immediate granularity of the target initiator configuration based on the initiator identifier of the connection request.

[0108] Optionally, based on the initiator identifier of the target initiator, query the immediate granularity corresponding to the target initiator configured in the target initiator.

[0109] Step 804: Initialize the target initiator according to the immediate granularity configured in the target initiator.

[0110] Memory resources are allocated for the immediate write requests of the target initiator based on the immediate granularity configured in the target initiator, for receiving data.

[0111] In the above embodiments, after receiving the connection request from the target initiator, the target initiator is initialized by querying its configuration, so that the target initiator can perform immediate write operations according to the configured immediate granularity.

[0112] Optional, such as Figure 9 The diagram illustrates the process by which the target initiator, upon receiving a connection request from the target initiator, performs immediate value configuration permission checks and configuration initialization. First, it retrieves the immediate value connection quota information. If no quota is available, the current connection does not support immediate value configuration. If quota information is successfully retrieved, it queries the immediate value granularity configuration parameters of the target initiator based on the target initiator identifier in the connection request. If the immediate value granularity configuration parameters are not found, the target initiator connection does not support immediate value configuration. In this case, the immediate value parameters of the connection request are reset, setting the supported immediate value size for this connection request to 0, meaning this connection request does not support immediate value requests. If the immediate value granularity configuration parameters of the target initiator are found, the immediate configuration is initialized and memory resources are allocated. If the request is successful, it continues to execute connection requests from other initiators until the request is completed. If the request fails, it resets the immediate value parameters of the connection request and then continues to execute connection requests from other initiators until the request is completed.

[0113] In embodiments of this application, the above-described request parameter configuration method may include, for example: Figure 10 The various modules within the system include: the application request processing module, which receives application requests, the IO sampling module performs IO sampling on the application request to obtain the application request data, and then sends a decision notification message to the immediate value configuration decision module to continue processing the application request.

[0114] The immediate value configuration decision module includes global immediate value connection quota decision and initiator immediate value idempotent decision. The global immediate value connection quota decision is used to predict and adjust the target's immediate value connection quota based on application request data. The specific process is as follows: Figure 7 As shown, the configuration and maintenance module is notified to update the immediate connection quota. The initiator immediate power-law decision is used to recalculate the power-law distribution ratio of initiator immediate write requests based on application requests, determining the initiator's immediate granularity configuration. The specific process is as follows: Figure 5 As shown, the configuration and maintenance module is then notified to update the immediate number granularity configuration parameters.

[0115] The immediate value configuration parameter maintenance module receives immediate value connection quota configuration update messages from the immediate value configuration decision module and updates the immediate value connection quota accordingly. It also receives immediate value granularity configuration update messages from the initiator and updates the initiator's immediate value granularity configuration. Simultaneously, when the above configurations are updated, an update message is sent to the memory resource management module to notify it to make resource management decisions.

[0116] The memory resource management module maintains a shared memory resource pool for each immediate value granularity exponential level. It receives memory resource management decision messages and expands or shrinks the memory resource pool accordingly. When the initiator's immediate value exponential level is updated, a notification message is sent to the memory resource management module. This notification message may include information such as the old exponential level and the new exponential level. The old exponential level is the immediate value granularity exponential level before the configuration update, and the new exponential level is the immediate value granularity exponential level after the configuration update. The process can be as follows: Figure 11 As shown. Simultaneously, a memory resource allocation interface is provided for the connection request module.

[0117] The initiator connection request processing module receives and processes connection requests from each initiator. It queries the immediate granularity configuration parameters of each initiator and performs initialization configuration.
