Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The core task of the storage device is to handle host read-write traffic. And after the storage equipment receives the resource calling request sent by the host, applying for the memory resource capable of processing the host read-write task resource to the storage array system. For example: memory capable of handling Input/Output (I/O) resources. However, due to limited storage resources in the storage device, in the processing process, as the number of read-write services processed by the host is continuously increased, the host is easy to call insufficient memory resources when processing the read-write services, and the situation of interrupt of the read-write services of the host is caused.
In order to solve the above-mentioned problems, in the embodiments of the present invention, a resource call control method is provided for a computer device, and it should be noted that an execution body of the resource call control method may be a resource call control device, and the device may be implemented by software, hardware, or a combination of software and hardware to form part or all of a storage device, where the storage device may be a terminal, a client, or a server, and the server may be a server, or may be a server cluster formed by multiple servers. In the following method embodiments, the execution subject is a storage device as an example.
In the storage device of the embodiment, the read-write task sent by at least one host connected with the storage device can be processed based on the storage resource in the storage device. Wherein the host is a host capable of supporting a SCSI protocol, which is a data transfer protocol. By way of the SCSI protocol, a host computer is enabled to establish a connection with a storage device, thereby enabling transfer of commands, status, and block data between the host computer and the storage device. In the resource calling control method provided by the invention, in the process of processing the read-write task sent by the host, under the condition that the resources allocated for the read-write task are exhausted and the read-write task is not processed, in order to ensure that the read-write task can be processed and completed, other types of resources can be called to continuously process the read-write task so as to ensure that the read-write task can be continuously performed, thereby ensuring the continuity of the read-write task of the host and reducing or avoiding the possibility that the read-write task is not processed and completed.
FIG. 1 is a flowchart of a resource call control method in accordance with an exemplary embodiment. As shown in fig. 1, the resource call control method includes the following steps S101 to S103.
In step S101, in response to the received read-write task of the host, the first storage resource is invoked to process the read-write task.
In the embodiment of the invention, the first storage resource is a resource for a read-write task allocated in the total memory resource. That is, the storage device invokes the first storage resource from the total memory resources in response to receiving the read-write task of the host, so as to process the read-write task through the first storage resource. In one example, the first storage resource may be understood as a general purpose memory resource.
In an embodiment, when the first storage resource is divided, the resource for the read-write task may be divided according to the number of cores of the CPU of the host. The more the number of CPU cores of the host is, the stronger the computing processing capability of the host is, and therefore, the more first storage resources are required to be occupied when the storage device processes the read-write task sent by the host. Therefore, in order to ensure that the first storage resource can be reasonably utilized, the situation that the first storage resource is wasted or insufficient due to unreasonable first storage resource when a read-write task is processed is avoided, and when the first storage resource is divided, the first storage resource can be divided according to the number of cores of a CPU (central processing unit) of a host connected with the storage device.
In another embodiment, the resources used for the read-write task may be shared resources when the number of cores of the CPU of the host is small. That is, the storage device can share the resources for the read/write task when processing the read/write task of each host. When the storage device currently receives the read-write task, according to the running state of the read-write task, a first storage resource for processing the read-write task is called from resources for the read-write task in real time, so that the distribution cost is reduced.
In step S102, when the first storage resource is exhausted and the read-write task is not processed, the second storage resource is called to continue processing the read-write task.
In the embodiment of the present invention, the second storage resource is a resource reserved for the host in the total memory resource. It is understood that the second storage resource is an emergency resource. The first storage resource is exhausted, which characterizes that the current read-write task has fully occupied the resources available to the host for the read-write task. However, when the first storage resource is exhausted and the read-write task is still not processed, the task is easy to be blocked, and the subsequent read-write task cannot respond. Therefore, in order to avoid the occurrence of the above situation, the second storage resource corresponding to the host is called to continue to process the read-write task, so that the read-write task can be successfully completed, and the occupied first storage resource can be released and reused.
In an embodiment, the division of the second storage resources corresponding to each host may be obtained by equally dividing the reserved resources according to the number of hosts connected to the storage device. The second storage resources are divided according to the number of the hosts, so that reserved resources can be quickly allocated, and allocation cost is reduced.
In step S103, when the second storage resource is exhausted and the read-write task is not processed, the temporary resource allocated by the stack space is called to process the read-write task.
In the embodiment of the invention, when the second storage resource is exhausted and the read-write task is not processed, the read-write task is characterized as being oversized, and the resource still needs to be called for continuous processing, so that the read-write task can be processed by calling the temporary resource distributed in the stack space. The stack space is adopted to call the temporary resources, so that the resources can be acquired quickly, the processing efficiency is improved, and the problem of interruption of the read-write service of the host computer caused by exhaustion of the memory resources can be avoided.
In an example, when the temporary resource is used for processing the read-write task, all the storage resources occupied by the read-write task can be released, including the occupied first storage resource and second storage resource, so that the read-write task is stopped to continue occupying the storage resources, the occupation pressure of the first storage resource is relieved, and the subsequent read-write task can call the first storage resource for processing, thereby achieving the purpose of avoiding the situation of task blocking.
Through the embodiment, under the condition that the resources for the read-write task are exhausted, other resources can be called for the read-write task which is processed currently, so that the processing task can be processed and completed, and the occupied first storage resource is released, and therefore the condition that the read-write service of a host is interrupted due to task blockage is avoided.
In an embodiment, to make the manner of resource call more flexible, the invention also provides another resource call control method.
FIG. 2 is a flowchart of another resource call control method in accordance with an exemplary embodiment. As shown in fig. 2, the resource call control method includes the following steps.
In step S201, in response to the received read-write task of the host, the first storage resource is invoked to process the read-write task.
In step S202, when the first storage resource is exhausted and the read-write task is not processed, the second storage resource is called to continue processing the read-write task.
In step S2031, when the second storage resource is exhausted and the read-write task is not processed, the temporary resource allocated by the stack space is called to process the read-write task.
In step S2032, when the second storage resource is occupied by the current subtask and cannot be called by other subtasks, the temporary resource allocated by the stack space is called to process the other subtasks.
In the embodiment of the invention, when the host sends the read-write task, the read-write task may comprise a plurality of subtasks. However, in the actual read-write task processing process, the process of processing the read-write task belongs to an asynchronous event. That is, resources may still be allocated to other sub-tasks during processing of the current sub-task to enable processing of other sub-resources.
When the second storage resource is occupied by the current subtask and cannot be called by other subtasks, the first storage resource is fully occupied, the second storage resource cannot allocate resources capable of processing other subtasks for the other subtasks, further, the other subtasks can be guaranteed to be continuously processed, the occurrence of task blocking is reduced, the allocated temporary resources are called from a stack space, and the other subtasks are continuously processed through the temporary resources, so that a resource calling mode is more flexible, and further, the occurrence of task blocking is reduced.
By the embodiment, a dynamic adjustment mode can be adopted, and under the condition that the first storage resource is exhausted, second storage resources or temporary resources in a stack space are allocated to a plurality of subtasks so that each subtask can be continuously processed, thereby being beneficial to reducing the occurrence of task blocking and reducing the possibility of interruption of host read-write business.
FIG. 3 is a flowchart of another resource call control method in accordance with an exemplary embodiment. As shown in fig. 3, the resource call control method includes the following steps.
In step S301, in response to the received read-write task of the host, the first storage resource is invoked to process the read-write task.
In step S302, when the first storage resource is exhausted and the read-write task is not processed, the second storage resource is invoked to continue processing the read-write task.
In step S303, abnormality information is sent to the host for notifying that the read-write task processing has failed.
In the embodiment of the invention, the abnormal information is information for informing that the processing of the read-write task fails, and is used for prompting that the first storage resource called for the read-write task is completely exhausted by the read-write task being processed by the host, and the resource used for the read-write task cannot execute other read-write tasks, and the subsequent read-write task corresponding to the host cannot continue to be processed in a task list of the storage device. By sending the abnormal information to the host, the host can be helped to automatically reduce or stop sending the read-write tasks according to the received abnormal information, so that the possibility that too many read-write tasks cannot be processed in time is reduced.
In an example, the processing result includes a read-write task processing error status code, and the read-write task processing error status code informs the host that the processing of the read-write task currently executed fails. In one implementation scenario, the read-write TASK processing error status code may be TASK FULL.
In step S3041, when the second storage resource is exhausted and the read-write task is not processed, the temporary resource allocated by the stack space is called to process the read-write task.
In step S3042, when the second storage resource is occupied by the current subtask and cannot be called by other subtasks, the temporary resource allocated by the stack space is called to process other subtasks.
According to the embodiment, under the condition that the first storage resource is exhausted, the failure of processing the read-write task is informed by sending the abnormal information to the host, so that the host can be further prompted to automatically reduce or stop sending the read-write task, and the possibility that too many read-write tasks cannot be processed in time is reduced.
FIG. 4 is a flowchart of another resource call control method in accordance with an exemplary embodiment. As shown in fig. 4, the resource call control method includes the following steps.
In step S401, in response to the received read-write task of the host, the first storage resource is invoked to process the read-write task.
In step S402, when the first storage resource is exhausted and the read-write task is not processed, the second storage resource is called to continue processing the read-write task.
In step S403, abnormality information is sent to the host for notifying that the read-write task processing has failed.
In step S4041, when the second storage resource is exhausted and the read-write task is not processed, the temporary resource allocated by the stack space is called to process the read-write task.
In step S4042, when the second storage resource is occupied by the current subtask and cannot be called by other subtasks, the temporary resource allocated by the stack space is called to process the other subtasks.
In step S405, a request stop notification is sent to the host for notifying the host to suspend sending of the read-write task request to the storage device based on the stack space.
In the embodiment of the invention, based on the characteristic of high processing efficiency of the stack space, when the temporary resources allocated by the stack space are adopted to process the read-write task, the response and the processing can be fast carried out. However, because the stack space is limited in storage space, the callable temporary resources may not meet the requirement of completing the processing of the read-write task, so that based on the stack space, a request stop notification is sent to the host to inform the host to stop sending the read-write task request to the storage device, so that the host can clearly determine that the storage device does not have redundant resources to process other read-write tasks currently, the accumulation quantity of the read-write tasks is reduced, the load pressure of the storage device is relieved, and the loss caused by the interruption of the read-write task of the host is reduced. In one example, the request stopping notification may further include notifying the host to resume processing the read-write task when the first storage resource has a free resource, so that the host can determine a time when the storage device processes the read-write task.
In an embodiment, when the request stop notification is sent to the host based on the stack space, the request stop notification may be set to a link (I-T-N) between the host (Initiator) and the storage device (Target) through temporary resources allocated by the stack space, so as to achieve the purpose of notifying the host to suspend sending the read-write task request to the storage device. In one example, the request stop notification may be a unit attention instruction (unit attention).
In an implementation scenario, when the storage device receives a read-write task sent by the host, the storage device responds to invoke a first storage resource (a general memory resource), and further processes the read-write task through the first storage resource. When the first storage resource is exhausted and the read-write TASK is not processed, the second storage resource (reserved memory resource) is called to continuously process the read-write TASK, and meanwhile, the TASK FULL is sent out to the host so as to inform that the processing of the currently executed read-write TASK fails. And when the second storage resource is exhausted and the read-write task is not processed, continuing to process the temporary resource allocated by the call stack space. If the temporary resources allocated by the stack space are exhausted and the read-write task is not completed, all the resources occupied by the read-write task are directly released, so that task blocking is avoided. And when the temporary resource is called, a request stop notification (unit notification) is set to the I-T-N based on the temporary resource to notify the host to pause sending the read-write task request to the storage device, and the read-write task is continuously processed when the general memory resource has idle storage resource.
Through the implementation scene, when the read-write task is processed, the read-write task is processed as far as possible by adopting the general processing resource and the temporary resource three-stage processing method of reserving the memory resource and the stack space, so that the continuity of the read-write service of the host is ensured, and the situation that the read-write task cannot be continuously processed due to resource exhaustion and the read-write service of the host is interrupted is avoided.
It should be understood that, although the steps in fig. 1-4 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
