[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] The cloud host configuration method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. The cloud computing platform 102 communicates with the terminal 104 through the network. The terminal 104 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices and portable wearable devices. The IoT devices may be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted devices may be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The cloud computing platform 102, also known as the cloud platform, is a service based on hardware resources and software resources, providing computing, network and storage capabilities. Specifically, during the process of cloud host configuration, the cloud computing platform 102 responds to the cloud host creation request received from the terminal 104, extracts request information from the cloud host creation request; based on the request information, determines the cloud host information that matches the cloud host creation request from the storage space; the cloud host information includes cloud host creation information and request restriction information; according to the cloud host creation information, creates a cloud host that matches the cloud host creation request; based on the request restriction information, creates a disk group corresponding to the cloud host; the request restriction information is used to limit the total request upper limit corresponding to each disk in the disk group.

[0046] In an exemplary embodiment, Figure 2 As shown, a cloud host configuration method is provided, which is applied to Figure 1 The cloud computing platform 102 in FIG. 1 is taken as an example to illustrate the method, which includes the following steps S202 to S208. Among them:

[0047] Step S202: In response to the received cloud host creation request, extract request information from the cloud host creation request.

[0048] The cloud host creation request refers to a request for creating a cloud host sent based on certain requirements. The request information refers to information associated with the cloud host creation request. For example, the request information may include configuration information, memory information, etc. of the cloud host.

[0049] Specifically, if a user wants to create a cloud host, he can send a cloud host creation request to the cloud computing platform based on the terminal. After receiving the cloud host creation request, the cloud computing platform can extract request information from the cloud host creation request to determine the specific cloud host creation status.

[0050] Step S204: Based on the request information, determine cloud host information matching the cloud host creation request from the storage space.

[0051] Among them, storage space refers to the storage space in the cloud computing platform, which stores the information and data needed in the cloud computing platform. Cloud host information mainly refers to the flavor information of the cloud host, that is, the virtual machine specification template, which defines the specification parameters such as disk size, number of CPUs, memory size, etc. Cloud host information includes cloud host creation information and request limit information. Cloud host creation information refers to the information required for the cloud host creation process. Request limit information refers to the information on the number of requests or request flow limit, generally referring to QoS (Quality of Service), that is, service quality information. In the storage system, QoS can bring customers restrictions on the number of read and write requests and read and write request flows. For example, the maximum number of requests and maximum flow values ​​can be set for specific users.

[0052] Specifically, after extracting the request information from the cloud host creation request, the user's need to create a cloud host can be determined. Therefore, the cloud host information matching the cloud host creation request can be determined from the storage space, which facilitates the subsequent creation and configuration of the cloud host according to the cloud host information. In some specific embodiments, the cloud computing platform can determine the user's intention to create a cloud host based on the request information, and match the corresponding cloud host information from the storage space based on the intention to create a cloud host.

[0053] Step S206: Create a cloud host that matches the cloud host creation request according to the cloud host creation information.

[0054] Specifically, after obtaining the cloud host creation information, the cloud host platform can create a cloud host matching the cloud host creation request according to the cloud host creation information. It is understood that the user can select various types of information of the cloud host to be created, for example, memory information, storage type information, etc. of the cloud host to be created.

[0055] Step S208: Create a disk group corresponding to the cloud host based on the request restriction information.

[0056] The request limit information is used to limit the total request limit for each disk in the disk group. A disk group is a logical storage unit composed of multiple physical disks (such as SSDs or HDDs) and is used to provide data storage and access services. In a cloud host environment, disk groups are often used to improve storage performance, reliability, and scalability.

[0057] Specifically, after obtaining the request limit information, the cloud computing platform can create a corresponding disk group for the cloud host based on the request limit information, that is, the total number of requests and the total request flow of all disks in the disk group are limited by the request limit information. In some specific embodiments, the disk group can be created by mobilizing related components, or the cloud computing platform can directly create the disk group.

[0058] The above cloud host configuration method extracts request information from the cloud host creation request in response to the received cloud host creation request, and can determine the request status of the cloud host creation. Based on the request information, the cloud host information matching the cloud host creation request is determined from the storage space, wherein the cloud host information includes cloud host creation information and request restriction information. According to the cloud host creation information, a cloud host matching the cloud host creation request is created, and the cloud host can be created. After that, based on the request restriction information, a disk group corresponding to the cloud host is created, and the request restriction of the disk group corresponding to the cloud host can be realized. Since the request restriction information is used to limit the total request upper limit corresponding to each disk in the disk group, the above method is used to configure the cloud host, and the total request upper limit of the cloud host can be stably controlled, ensuring the stability of the cloud host configuration, and then ensuring the stability of the entire cloud computing system.

[0059] In an exemplary embodiment, based on the request information, cloud host information matching the cloud host creation request is determined from the storage space, including: based on the request information, determining the creation intention corresponding to the cloud host creation request; and using the target cloud host information that meets the creation intention among multiple candidate cloud host information stored in the storage space as the cloud host information matching the cloud host creation request.

[0060] The creation intention refers to the user's inner tendency or intention to create a cloud host. The candidate cloud host information refers to the cloud host information that may be selected.

[0061] Specifically, the cloud computing platform can determine the creation intention corresponding to the cloud host creation request based on the request information, thereby determining the user's inner tendency or intention to create a cloud host. Afterwards, based on the user's inner tendency or intention to create a cloud host, the platform can select the target cloud host information that matches the creation intention from multiple candidate cloud host information stored in the storage space as the cloud host information that matches the cloud host creation request, thereby ensuring the accuracy of the cloud host information.

[0062] In an exemplary embodiment, the cloud host configuration method further includes: converting the format of the request restriction information according to a preset information format to obtain conversion restriction information; and storing the conversion restriction information in a storage space.

[0063] The preset information format refers to an information organization form or rule that is set in advance when creating, storing or processing information. In this embodiment, the preset information format refers to the XML format. In this embodiment, the storage space refers to libvirt XML. Specifically, the configuration of the cloud host in libvirt is described by an XML file. This XML file contains various configuration information of the cloud host, such as CPU, memory, disk, network interface, etc. By editing this XML file, the user can customize the configuration of the cloud host.

[0064] Specifically, in order to facilitate the creation of subsequent disk groups, the cloud computing platform needs to first convert the request restriction information according to a preset information format to obtain conversion restriction information, and then store the conversion restriction information in a storage space to facilitate subsequent acquisition of the conversion restriction information from the storage space. Furthermore, it can also facilitate the creation of subsequent disk groups.

[0065] In an exemplary embodiment, creating a disk group corresponding to a cloud host based on request restriction information includes: obtaining conversion restriction information from a storage space; and calling a storage development kit to create a disk group corresponding to the cloud host based on the conversion restriction information.

[0066] The Storage Performance Development Kit (SPDK) is a storage development kit designed specifically for dedicated devices (NVME). SPDK provides a series of high-performance, scalable, user-mode tools and libraries.

[0067] Specifically, in order to ensure the stability of the disk group creation process, the cloud computing platform can first obtain conversion restriction information from the storage space, and then, based on the conversion restriction information, call the storage development kit to create a disk group corresponding to the cloud host.

[0068] In an exemplary embodiment, the cloud host configuration method also includes: obtaining multiple candidate disks from the cloud computing system, and determining a target disk mounted in the cloud host from each candidate disk; adding the target disk mounted in the cloud host to the disk group.

[0069] The candidate disk refers to a disk that may be selected.

[0070] Specifically, after creating a disk group, you also need to assign corresponding disks to the disk group. Since cloud hosts correspond to disk groups one by one, you need to first obtain multiple candidate disks from the cloud computing system, and from each candidate disk, determine the target disk mounted in the cloud host, and finally add the target disk mounted in the cloud host to the disk group.

[0071] In this embodiment, the target disk mounted in the cloud host is added to the disk group, which can ensure the normal configuration of the cloud host.

[0072] In an exemplary embodiment, the cloud host configuration method further includes: determining disk group configuration information for the disk group in response to a received disk group configuration event; and updating the number of disks in the disk group based on the disk group configuration information.

[0073] The disk group configuration event usually involves operations of creating, modifying or managing a disk group in a storage system. The disk group configuration information is the relevant information for configuring the disk group. For example, the disk group configuration information may be information for adding or deleting a disk in the disk group.

[0074] Specifically, a cloud host can mount multiple disks, and the number of disks is not fixed, that is, the number of disks can be increased or decreased. Therefore, after receiving the disk group configuration event, the cloud computing platform determines the disk group configuration information for the disk group, and then updates the number of disks in the disk group based on the disk group configuration information. For example, when the disk group configuration information for the disk group is to delete a disk, the cloud computing platform needs to delete one of the disks in the disk group and update the number of disks in the disk group. Similarly, when the disk group configuration information for the disk group is to add a new disk, the cloud computing platform needs to add a new disk to the disk group and update the number of disks in the disk group. Exemplary, such as Figure 3As shown, vm1, vm2... correspond to multiple cloud hosts, each cloud host contains multiple disks (disk1, disk2...), and disk1, disk2...) correspond to a disk group.

[0075] In this embodiment, the cloud computing platform can update the number of disks in the disk group according to the disk group configuration information, and can flexibly adapt to the user's disk configuration requirements.

[0076] In a specific embodiment, a cloud host configuration method in an actual application scenario is also provided, and the specific steps are as follows: Figure 4 As shown:

[0077] S1: The cloud computing side configures the QoS of the entire machine and transmits it to the virtualization layer.

[0078] S11: Add parameters to the cloud host flavor and save the QoS parameters of the entire machine in the flavor.

[0079] S12: When the cloud host is created, the QoS parameters of the entire machine in the flavor are obtained and initialized and filled into libvirtxml.

[0080] S2: The virtualization layer obtains the QoS parameters of the entire machine and calls SPDK to create QoS. The specific steps are as follows:

[0081] S21: When the cloud host creates a disk, the virtualization obtains XML parameters and determines whether the whole machine QoS parameters exist. If so, SPDK is called to create a disk group and set the QoS parameters to the disk group.

[0082] S22: When the cloud host mounts the SPDK cloud hard disk (disk), the virtualization calls SPDK to add the cloud hard disk to the disk group; correspondingly, if the cloud host uninstalls the SPDK cloud hard disk, the cloud hard disk is removed from the disk group.

[0083] S3: SPDK creates QoS, specific steps:

[0084] S31: SPDK obtains the virtualization input parameters to create a disk group.

[0085] S32: SPDK adds the disk mounted to the cloud host to the disk group marked with the cloud host. DETAILED DESCRIPTION

[0086] S1: The cloud computing side configures the QoS of the entire machine and transmits it to the virtualization layer;

[0087] S11: Add parameters to the cloud host flavor, configure the whole machine QoS parameters in the flavor, and add the whole machine QoS parameters in the additional configuration of the flavor. The QoS parameters include DISK:IOPS_BASE (cloud host whole machine IOPS) and DISK:BANDWIDTH_BASE (cloud host whole machine bandwidth) and specify the IOPS and bandwidth values.

[0088] S12: A new method is added to the computing layer to generate the XML model of the whole machine QoS and fill it into libvirtxml during the cloud host spawn phase. The specific process is as follows Figure 5 As shown;

[0089] S121: When the cloud host is created, it is determined whether the flavor contains the whole machine QoS parameters. If so, S122 is executed. If not, the method ends.

[0090] S122: Obtain the whole machine QoS parameters in the flavor and generate an XML model of the whole machine QoS according to the libvirtxml model.

[0091] S123: In the cloud host spawn phase, the initialized whole-machine QoS XML is filled into libvirtxml.

[0092] S2: The virtualization layer obtains the QoS parameters of the entire machine and calls SPDK to create QoS. The specific process is as follows Figure 6 As shown;

[0093] S21: When the cloud host is created, the virtualization obtains the parameters in libvirtxml and determines whether there are whole-machine QoS parameters in the parameters. If there are whole-machine QoS parameters, SPDK is called to create a disk group and set QoS for the disk group. The IOPS and bandwidth values ​​of the disk group QoS are the corresponding parameter values ​​in the whole-machine QoS. The cloud host and the disk group correspond one to one. If there are no whole-machine QoS parameters, exit without additional processing.

[0094] S22: When the cloud host mounts the SPDK cloud hard disk, the virtualization calls SPDK to add the cloud hard disk to the disk group corresponding to the cloud host; the cloud hard disks in the same disk group share the disk group QoS. Correspondingly, if the cloud host uninstalls the SPDK cloud hard disk, the cloud hard disk will be removed from the disk group corresponding to the cloud host.

[0095] S3: SPDK creates QoS;

[0096] S31: SPDK obtains the virtualization input parameters to create a disk group. The disk group and the cloud host correspond one to one, and sets QoS for the disk group. The QoS value of the disk group is the QoS value of the entire cloud host.

[0097] S32: SPDK adds the disk mounted to the cloud host to the disk group corresponding to the cloud host. When the cloud host unmounts the disk, SPDK removes the corresponding cloud hard disk from the disk group.

[0098] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0099] The method of implementing cloud host QoS based on SPDK disk group QoS solves the problem that a single cloud host occupies most of the host storage network resources when the host resources are limited in the current cloud computing system, resulting in storage performance degradation and instability of other cloud hosts on the same host, thereby achieving reasonable resource utilization and ensuring the stability of each cloud host's disk business capabilities.

[0100] In a specific embodiment, Figure 7 As shown, a cloud host configuration method is also provided, including:

[0102] Step S702, using the target cloud host information that meets the creation intention among the multiple candidate cloud host information stored in the storage space as the cloud host information that matches the cloud host creation request;

[0103] The cloud host information includes cloud host creation information and request restriction information;

[0104] Step S703, creating a cloud host matching the cloud host creation request according to the cloud host creation information, and converting the request restriction information according to a preset information format to obtain conversion restriction information;

[0105] Step S704, storing the conversion restriction information in the storage space, obtaining the conversion restriction information from the storage space, and calling the storage development kit to create a disk group corresponding to the cloud host based on the conversion restriction information;

[0106] The request limit information is used to limit the total request limit corresponding to each disk in the disk group;

[0107] Step S705, obtaining multiple candidate disks from the cloud computing system, and determining a target disk mounted in the cloud host from each candidate disk;

[0108] Step S706, adding the target disk mounted in the cloud host to the disk group;

[0109] Step S707 : in response to the received disk group configuration event, determine disk group configuration information for the disk group, and update the number of disks in the disk group based on the disk group configuration information.
