Description

Mirror image deployment method, device, equipment and storage medium

Technical Field

The present application relates to the field of computer technologies, and in particular, to a method, an apparatus, a device, and a storage medium for deploying a mirror image.

Background

With the continuous development of Computer technology, enterprises have higher and higher requirements on Computer storage performance, and conventional storage protocols, such as Internet Small Computer System Interface (iSCSI), have been unable to meet the requirements in some specific service scenarios.

In order to support network storage of a data center, a Non-Volatile Memory (NVMe) fusion Fabric (NVMeOF) is proposed in the prior art. The extension of the NVMe standard on a Peripheral Component Interconnect express (PCIe) standard can be realized by the NVMeOF. In addition, NVMe may be mapped to multiple fabric (Fabrics) Transmission options through NVMeOF, and the Fabrics Transmission options may include Fibre Channel (FC), wireless bandwidth (InfiniBand, IB), Remote Direct data Access (RDMA) second version (v2) of RDMA over Ethernet (RoCE), Internet Wide Area RDMA Protocol (Wide Area RDMA Protocol), Transmission Control Protocol (TCP), and the like. The mapping of NVMe to multiple fabric (Fabrics) transmission options enables the data center and the storage system to communicate with each other through a network, so that the data center can access an NVMe Solid State Disk (SSD) in the storage system. The data center may include a host, among other things. Thereby enabling faster access between the host and the storage system.

Therefore, NVMeOF has lower latency compared to iSCSI, but needs the functionality needed to maintain traffic while replacing iSCSI, and there is a lack in the prior art of methods for automated image deployment in hosts based on NVMeOF.

Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

Compared with iSCSI, NVMeOF has lower delay, but the functions required by the maintenance of the service are required while replacing iSCSI, and the method for automatically deploying the image in the host based on NVMeOF is lacked in the prior art. In order to solve the problem, an embodiment of the present application provides an image deployment method, and specifically, an image may be automatically deployed in a host based on NVMeOF. A detailed description is given below of a mirror image deployment method provided in the embodiments of the present application with reference to specific embodiments.

FIG. 1 shows a flowchart of an image deployment method according to an embodiment of the present application. As shown in fig. 1, the method may include:

s101, the first device sends a query request to the database, and the query request is used for querying the number of the mirror images.

The mirror image deployment method described in this embodiment may be applied to the application scenario shown in fig. 2. As shown in fig. 2, the application scenario includes a first device 21, a database 22, a switch 23, a second device 24, a third device 25, and a storage system 26. The number of the second devices 24 is not limited to one, and may be multiple, for example, and two second devices 24 are taken as an example to be schematically illustrated here. Similarly, the number of the third devices 25 is not limited to one, and may be a plurality of third devices, and two third devices 25 are exemplified here for illustrative purposes. Wherein the first device 21 may communicate with the database 22 and the switch 23, respectively, the database 22 may be integrated in the first device 21, or the first device 21 and the database 22 may be independent from each other. The switch 23 may communicate with the second device 24 and the storage system 26, respectively. The second device 24 may communicate with a third device 25.

Specifically, the storage system 26 may include an image, which may be a disk volume, which may be understood as a storage unit or storage space in the storage system 26. In addition, the disk volume can also be recorded as a template clone volume. The database 22 may store the number of images and a Universal Unique Identifier (UUID) of each image. The first device 21 may specifically be a Bare Metal Server (BMS). The first device 21 may send a query request to the database 22, the query request being for a query of the number of images. Alternatively, in some embodiments, the query request is used to query the number of images and the UUID of each image. The mirror quantity may be specifically a template clone volume inventory quantity.

And S102, the first device receives the mirror image number from the database.

In case the database 22 receives the query request, the database 22 may send the mirrored amount to the first device 21, and accordingly the first device 21 receives the mirrored amount from the database 22.

S103, the first device acquires the first address information of the second device from the database according to the mirror image quantity.

As shown in fig. 2, the second device 24 may specifically be a Network Interface Controller (NIC), which may also be called a Network Adapter (Network Adapter), a Network Card (Network Interface Card), or a Local Area Network receiver (Local Area Network Adapter), and is a piece of computer hardware designed to allow a computer to communicate over a computer Network. Where RoCE may be a network protocol that allows RDMA over Ethernet, the frame header, i.e., the network header, may be an Ethernet header, the data portion of the frame format of the network protocol may include an InfiniBand header, thereby allowing RDMA to be used on a standard Ethernet infrastructure (switch), and the NIC may be special, e.g., may be an adapter or interface card that reduces latency and CPU usage. The adapter may register a direct storage area that may be used by the application so that the third device 25 may pass the data to be transferred directly to the storage system.

For example, the database 22 may also store address information for the second device 24. The second device 24 may obtain address information of the second device 24 from the database 22 according to the number of images, where the address information may specifically be an Internet Protocol (IP) address, and the IP address of the second device 24 may be recorded as the first address information.

And S104, the first device mounts the mirror image in the storage system into the second device according to the first address information, wherein the second device is used for setting the mirror image as a starting item of the third device.

The first device 21 may mount the image in the storage system to the second device 24 according to the IP address of the second device 24, and further, the second device 24 may map the image to a local block device and set the image as a special boot entry of the third device 25. The third device 25 may specifically be a Physical Server (Physical Server). The second device 24, e.g. the RoCE NIC, may be a network card of the third device 25, in which case the RoCE NIC may be provided in the third device 25. Alternatively, in some embodiments, the second device 24 and the third device 25 may be separate devices. In addition, the third device 25 may also be referred to as a host.

According to the method and the device, the query request is sent to the database through the first device, the number of the mirror images is queried from the database, the first address information of the second device is obtained from the database according to the number of the mirror images, further, the mirror images are mounted on the second device according to the first address information of the second device, the second device can set the mirror images as the starting items of the third device, and therefore the first device can automatically deploy the mirror images in the third device through the second device. For example, when the second device is a RoCE NIC, the first address information is an IP address, and the third device is a host, the first device sends a query request to the database, queries the number of images from the database, and obtains the IP address of the RoCE NIC from the database according to the number of images, and further mounts the images onto the RoCE NIC according to the IP address of the RoCE NIC, and the RoCE NIC sets the images as a start item of the host, so that the first device can automatically deploy images in the host through the RoCE NIC.

FIG. 3 shows a flow diagram of an image deployment method according to another embodiment of the present application. As shown in fig. 3, the method may include:

s301, the first device sends a query request to the database, and the query request is used for querying the number of the mirror images.

The first device 21 may send a query request to the database 22, the query request being for a query of the number of images.

S302, the first device receives the mirror image number from the database.

And S303, under the condition that the number of the images is greater than or equal to 1, the first device acquires the first address information of the second device from the database. S307 may be performed after S303.

For example, in the case that the number of images is greater than or equal to 1, the first device 21 may directly obtain the first address information of the second device 24 from the database 22, for example, the IP address of the RoCE NIC. It is understood that the first device 21 directly obtains the first address information of the second device 24 from the database 22 is not limited to the case that the number of images is greater than or equal to 1, and may also be performed, for example, if the number of images is greater than or equal to 2, 3 or other positive integer. The number of images greater than or equal to 1 in this embodiment is only an illustrative example of images with stock in the storage system. In addition, in a case where the first device 21 acquires the first address information of the second device 24, the first device 21 may further perform S307 described below.

S304, under the condition that the mirror quantity is equal to 0, the first device creates a mirror in the storage system.

For example, in the case where the number of images is equal to 0, the first device 21 may create an image in the storage system 26. As shown in fig. 2, the first device 21 may communicate with the storage system 26 through the switch 23. For example, the first device 21 may communicate with the switch 23 through a BMS Application Programming Interface (API), the Storage system 26 may be a Storage Area Network (SAN), and the switch 23 may communicate with the SAN through the SAN API. So that the first device 21 can call the SAN API through the BMS API and create an image in the storage system 26 through the SAN API. For example, the first device 21 obtains the clone template in the storage system 26 by calling the SAN API, and further, the first device 21 clones a new template clone volume according to the clone template, the new template clone volume being an image created in the storage system 26 by the first device 21. The SAN API may also be denoted as a storage API. The BMS API may perform, among others, disk volume lifecycle management, disk volume QoS management, RoCE network card control, NVMe target (target) control, and the like.

Optionally, the creating, by the first device, an image in the storage system includes: the first device creates an image in the storage system, sets quality of service of the image, and acquires identification information of the image.

For example, in the case where the first device 21 creates an image in the storage system 26, the first device 21 may also set Quality of Service (QoS) of the image and acquire identification information of the image, such as a UUID.

S305, the first device stores the related information of the created mirror image in the database.

For example, after the first device 21 creates an image in the storage system 26, the first device 21 may further store the information about the created image in the database 22.

Optionally, the first device stores the information about the created image in the database, including: the first device stores the quality of service of the created image and the identification information of the image in the database.

For example, the first device 21 may store the QoS and UUID of the image it creates in the database 22. In some embodiments, the first device 21 may also update an image (image) table in the database 22, which may include identification information of each image, and an identification field of each image for identifying whether the image is configured as a server image. For example, the first device 21 may configure the image as a server image in the image table. The server image may specifically be an image in a physical server.

S306, the first device acquires the first address information of the second device from the database.

For example, the second device 24 may obtain the IP address of the second device 24 from the database 22.

S307, the first device mounts the mirror image in the storage system to the second device according to the first address information, and the second device is used for setting the mirror image as a starting item of the third device.

For example, in a case that the number of the images is greater than or equal to 1, the first device 21 may mount an existing image in a storage system as a target to the second device 24 according to an IP address of the second device 24, where the storage system may include a plurality of images, and the image that the first device 21 mounts to the second device 24 may be any one of the plurality of images.

In the case where the number of images is equal to 0, the first device 21 may mount the image created by the first device 21 in the storage system as a target in the second device 24 according to the IP address of the second device 24.

According to the embodiment of the application, when the number of the images is equal to 0, the first device creates the images in the storage system, stores the related information of the created images in the database, acquires the first address information of the second device from the database, mounts the created images to the second device according to the first address information, and the second device further sets the images as the starting items of the third device, so that the third device, such as a host, can normally deploy the images when the inventory number of the images is 0, and the reliability of image deployment is improved.

For example, in some embodiments, on the basis of fig. 2, the application scenario may further include a fifth device, and the fifth device may specifically be a Dynamic Host Configuration Protocol (DHCP) server. As shown in fig. 4, a second device 24, such as a RoCE NIC, is integrated in a third device 25, and the third device 25 may communicate with a fifth device 27 through the switch 23.

On the basis of the above embodiment, the mirror image deployment method further includes: the first device sends first configuration information to a fourth device, the first configuration information is used for configuring a port of the fourth device, the port of the fourth device is used for communication between the third device and a fifth device, and the fifth device is used for configuring second address information of the third device.

The fourth device may specifically be the switch 23 as described above, for example. For example, the first device 21 may further send, to the switch 23, first configuration information that configures a Virtual Local Area Network (VLAN) of a port of the switch 23, so that the third device 25 and the fifth device 27 can communicate through the port. The fifth device 27 may configure the third device 25 with second address information of the third device 25, where the second address information may be an IP address of the third device 25.

Optionally, the mirror image deployment method further includes: the first device sends a restart control instruction to the third device, where the restart control instruction is used to control the third device to restart, and after the third device is restarted, the third device is used to obtain the second address information from the fifth device.

For example, the first device 21 may send a restart control instruction to the third device 25, and in a case where the third device 25 receives the restart control instruction, the third device 25 may restart according to the restart control instruction, and after the third device 25 restarts, the third device 25 may acquire the IP address of the third device 25 from the fifth device 27 through the port of the switch 23. In other embodiments, the first device 21 may also reset the startup entry of the server, e.g., the third device 25.

Optionally, the mirror image deployment method further includes: and the first device determines the corresponding relation between the fourth address information and the fifth address information according to the corresponding relation between the third address information of the third device and the fourth address information of the fifth device, which is locally stored, and the corresponding relation between the third address information and the fifth address information of the public network, which is stored in the database.

For example, the first device 21 may locally store a corresponding relationship or a binding relationship between third address information of the third device 25 and fourth address information of the fifth device 27, where the third address information of the third device 25 may specifically be a Media Access Control (MAC) address of the third device 25, and the fourth address information of the fifth device 27 may specifically be an IP address of the fifth device 27. In addition, the database 22 further stores a corresponding relationship between the MAC address of the third device 25 and a public network IP address, where the public network IP address may be recorded as fifth address information of the public network. The first device 21 may also obtain the correspondence between the MAC address of the third device 25 and the public network IP address from the database 22. Further, the first device 21 may determine the correspondence between the IP address of the fifth device 27 and the public network IP address according to the correspondence between the MAC address of the third device 25 and the IP address of the fifth device 27, which is locally stored by the first device, and the correspondence between the MAC address of the third device 25 and the public network IP address, which is acquired from the database 22.

Optionally, the mirror image deployment method further includes: and the first device sends second configuration information to the third device, wherein the second configuration information is used for modifying the fourth address information stored in the third device into the fifth address information.

For example, the first device 21 may further send, to the third device 25 through the switch 23, second configuration information for modifying the IP address of the fifth device 27 stored in the third device 25 to the public network IP address, so that the third device 25 may communicate with the public network. Specifically, the first device 21 may call a BMS Agent (Agent) in the third device 25 and configure a service IP address through the BMS Agent, where the process of configuring the service IP address may be a process of modifying an IP address of the fifth device 27 stored in the third device 25 into a public network IP address, so as to complete operations such as system initialization of the third device 25.

In addition, the physical server is restarted through the first device, so that the physical server can successfully acquire the IP address of the physical server after being restarted. In addition, the first device can acquire the corresponding relation between the IP address of the DHCP server and the public network IP address according to the corresponding relation between the MAC address of the physical server and the IP address of the DHCP server which are locally stored in the first device and the corresponding relation between the MAC address of the physical server and the public network IP address in the database, and further, the first device modifies the IP address of the DHCP server which is stored in the physical server into the public network IP address, so that the physical server can normally communicate with the public network.

FIG. 5 shows a flow diagram of a method of image deployment according to another embodiment of the present application. As shown in fig. 5, the method may include:

s501, the second device receives the mounting instruction sent by the first device.

For example, the first device 21 may send a query request to the database 22, the query request being for a query of the image quantity. In case the database 22 receives the query request, the database 22 may send the mirrored amount to the first device 21, and accordingly the first device 21 receives the mirrored amount from the database 22. In the case that the number of images is greater than or equal to 1, the first device 21 may directly acquire the first address information of the second device 24 from the database 22, for example, the IP address of the RoCE NIC. In the case where the number of images is equal to 0, the first device 21 may create an image in the storage system 26, set Quality of Service (QoS) of the image, and acquire identification information of the image, such as a UUID. After the first device 21 creates the image in the storage system 26, the first device 21 may further store the information related to the created image in the database 22, and obtain the IP address of the second device 24 from the database 22. In addition, when the number of the images is greater than or equal to 1, the first device 21 may mount an image existing in a storage system as a target to the second device 24 according to an IP address of the second device 24, where the storage system may include a plurality of images, and the image that the first device 21 mounts to the second device 24 may be any one of the plurality of images. In the case where the number of images is equal to 0, the first device 21 may mount the image created by the first device 21 in the storage system as a target in the second device 24 according to the IP address of the second device 24. In a specific overload process, the first device 21 may send a mount instruction to the second device 24, and correspondingly, the second device 24 may receive the mount instruction sent by the first device 21, where the mount instruction is used to instruct the second device 24 to mount the mirror image in the second device 24.

And S502, the second device mounts the mirror image in the storage system into the second device according to the mounting instruction.

For example, the second device 24 may mount the mirror image in the storage system to the second device 24 according to the mounting instruction.

And S503, the second device sets the image as a starting item of the third device.

Optionally, the setting, by the second device, the image as a boot item of the third device includes: the second device maps the image to a local block device and sets the image as a boot entry of the third device.

For example, the second device 24, for example, a RoCE NIC is integrated in the third device 25, and in a case that the fifth device 27 transmits a data stream to the third device 25 through the switch 23, the RoCE NIC may perform TCP RDMA decapsulation on a data packet in the data stream, map the mirror image to a local block device, and set the mirror image as a special start item of the third device 25. The specific process of TCP RDMA decapsulation for the data packet in the data stream by the RoCE NIC may be a process of Kernel-bypass (Kernel-bypass) performed by the RoCE NIC, that is, the RoCE NIC strips data carried by TCP from an RDMA protocol. In addition, RDMA, a host-offload (host-offload) technology, can implement low-latency, high-bandwidth direct memory-to-memory data communication, and RDMA convergence Ethernet (RoCE), RDMA over Ethernet, allows a network protocol for performing RDMA over Ethernet. This allows RDMA to be used on standard ethernet infrastructures (switches), where the network card may be a special NIC supporting RoCE.

In the embodiment of the application, the first device sends a query request to the database, queries the number of images from the database, and obtains the IP address of the RoCE NIC from the database according to the number of images, and further mounts the images onto the RoCE NIC according to the IP address of the RoCE NIC, and the RoCE NIC sets the images as the start items of the host, so that the first device can automatically deploy the images in the host through the RoCE NIC.
