Wherein the communication bus 1002 is used to enable connected communication between these components. The user interface 1003 may include a Display (Display), and the optional user interface 1003 may also include a standard wired interface, a wireless interface, and the wired interface for the user interface 1003 may be a USB interface in the present invention. The network interface 1004 may optionally include a standard wired interface, a Wireless interface (e.g., a Wireless-Fidelity (Wi-Fi) interface). The Memory 1005 may be a high-speed random access Memory (Random Access Memory, RAM) or a stable Memory (NVM), such as a disk Memory. The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the structure shown in fig. 1 does not constitute a limitation of the data migration apparatus, and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.
As shown in FIG. 1, an operating system, network communications module, user interface module, and data migration program may be included in memory 1005, which is considered a type of computer storage medium.
In the data migration apparatus shown in fig. 1, the network interface 1004 is mainly used for connecting to a background server, and performing data communication with the background server; the user interface 1003 is mainly used for connecting user equipment; the data migration device invokes a data migration program stored in the memory 1005 through the processor 1001, and executes the data migration method provided by the embodiment of the present invention.
Based on the above hardware structure, an embodiment of the data migration method of the present invention is presented.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a data migration method according to the present invention.
In this embodiment, the data migration method includes the following steps:
step S10: and detecting the hardware configuration type of the target virtual machine when the data migration instruction is received.
It should be noted that, in this embodiment, the execution body may be a disaster recovery integrated machine connected to the target source machine and the target virtualization platform, where the disaster recovery integrated machine may be a device with a data migration function, and the target source machine may refer to a protected computer device (data transmission end), where the device is as follows: the virtual platform may be a computer and its matched equipment used in the information and system science related engineering and technology field, where the target virtual machine may be used as a data receiving end to receive data sent by the source machine, so as to implement data synchronization operation, and the target virtual machine may refer to a host running on the virtual platform, which is not limited in this embodiment. This embodiment and the following embodiments will be described by taking the disaster recovery integrated machine as an example.
It is understood that the data migration instruction may be an instruction generated by a source machine, or may be an instruction fed back by a virtualization platform, for example: the instruction may be a preset data migration instruction generated according to a push time period, or may be a data migration instruction generated according to push data traffic, or may be an instruction fed back when the virtualization platform receives that the pushed data amount reaches a preset threshold, which is not limited in the application.
It should be appreciated that different types of hardware configurations have very large performance differences. For example: the read-write monitoring of the virtual hard disk is carried out on the high-performance virtio (paravirtualized) type hard disk and the low-performance ide (fully virtualized) type hard disk, so that the performance of the virtio is several times that of the ide (more than ten times can be achieved under a pure SSD cluster environment); the high-performance virtio (paravirtualized) type network card and the low-performance 8139D (fully virtualized) type network card are subjected to receiving and transmitting monitoring of the virtual network card, and the performance of the virtio is more than twenty times of that of 8319D; it can be seen that the high performance hard disk and network card type is faster in data read and write, and the above model is only for illustration and not limitation. Therefore, in order to ensure the transmission speed of the virtual machine in data migration, the hardware configuration type of the target virtual machine needs to be detected before data pushing is performed, so that the target virtual machine is ensured to complete data transmission according to the high-performance configuration under the condition that the high-performance configuration is met.
Step S20: and carrying out configuration adjustment on the target virtual machine according to the highest performance supported by the hardware configuration type.
It should be noted that, in order to ensure the data transmission efficiency, when the hardware configuration type does not meet the highest performance configuration condition, the target virtual machine may be configured and adjusted according to the highest performance supported by the hardware configuration type, so that the hardware configuration type of the target virtual machine supports the highest performance to perform data transmission.
Step S30: and transmitting the data to be migrated to the target virtual machine after configuration adjustment.
It should be noted that, before pushing data, it is detected whether the hardware configuration of the target virtual machine is the highest performance configuration, if so, data is pushed to the target virtual machine.
In specific implementation, pushing data means that disk data of a source machine is migrated to a target machine, so that the target machine data is consistent with the source machine data, thereby achieving the purpose of disaster recovery, one disaster recovery task can push the data for multiple times, before each time of pushing the data, the hardware configuration type of the target virtual machine is detected, and if the current configuration of the target virtual machine is the highest-performance hardware configuration, the data is pushed; otherwise, the hardware configuration type of the target virtual machine needs to be adjusted to be the highest performance configuration, and then data is pushed to the target virtual machine.
Further, the step S30 includes: writing the data to be migrated in the target source machine into a file of a path corresponding to the target virtual machine after configuration adjustment according to a preset file system mapping relation; or writing the data to be migrated of different block devices in the target source machine into the corresponding configured and adjusted target virtual machine block devices according to the same offset according to the preset block device mapping relation.
It should be noted that, the target virtual machine includes a data receiving module, where the data receiving module works in an operating system supporting high-performance virtual devices and is mainly used for writing data from the source machine into a disk of the target virtual machine, where the data pushing stage includes two preset data receiving modes, where the modes include: data reception is performed on a file basis and data reception is performed on a block basis (e.g., a disk data volume).
It should be understood that, since the target virtual machine includes two data receiving modes, two data transmission modes are included in the data pushing stage, that is, the data to be migrated in the target source machine is written into the file of the corresponding path of the target virtual machine after configuration adjustment according to the mapping relation of the preset file system, and the data to be migrated of different block devices in the target source machine is written into the corresponding target virtual machine block device after configuration adjustment according to the same offset according to the mapping relation of the preset block device. The data transmission mode can be set according to actual conditions.
It can be understood that the target virtual machine determines a corresponding data receiving mode according to the data transmission mode, so that if the target virtual machine receives data according to the file, the receiving data module can identify the file system in the disk, establish a mapping relationship from the file system of the source machine to the file system of the target virtual machine, and write the file data in the source machine into the file of the corresponding path; and if the target virtual machine receives data according to the block devices (disk and data volume), establishing a mapping relation between the source machine block device and the block devices in the target virtual machine in the receiving module, and writing different block device data in the source machine into the corresponding target virtual machine block device according to the same offset.
In the embodiment, when a data migration instruction is received, the hardware configuration type of the target virtual machine is detected; configuring and adjusting the target virtual machine according to the highest performance supported by the hardware configuration type; and transmitting the data to be migrated to the target virtual machine after configuration adjustment. Because the hardware configuration type of the target virtual machine is dynamically adjusted, so that the hardware configuration of the target virtual machine supports the highest performance, compared with the low-performance configuration in which the target virtual machine is consistent with the source machine because the source machine does not support the high-performance configuration in the prior art, the data transmission speed is low, and the disaster recovery efficiency is low.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of the data migration method according to the present invention, and the second embodiment of the data migration method according to the present invention is proposed based on the first embodiment shown in fig. 2.
In this embodiment, the hardware configuration type includes a hard disk type and a network card type; the step S10 includes:
step S100: and when receiving the data migration instruction, detecting whether the hard disk type and the network card type of the target virtual machine meet the highest performance configuration condition.
It should be noted that, in the scheme, the hard disk type and the network card type of the target virtual machine are detected before data pushing to judge whether the current configuration of the target virtual machine meets the highest performance configuration condition, so that the hardware configuration of the target virtual machine can be dynamically adjusted in time before data pushing.
The step S20 includes:
step S200: and according to the detection result, the target virtual machine is configured and adjusted according to the highest performance supported by the hard disk type and the network card type.
It should be noted that, if the current hard disk type and the network card type of the target virtual machine are both high performance, no adjustment operation is performed on the target virtual machine; otherwise, the hard disk and/or the network card of the target virtual machine need to be set to a high-performance type.
In a specific implementation, referring to the hardware configuration adjustment schematic diagram described in fig. 4, the hard disk and/or the network card of the target virtual machine are adjusted accordingly according to the detection result. If the hard disk type and the network card type of the target virtual machine are both high-performance, no modification type operation is performed, and if the hard disk type and/or the network card of the target virtual machine are not high-performance, the hardware configuration which does not belong to the high-efficiency type is modified to be high-performance, so that the hard disk type and the network card type of the target virtual machine are both high-performance, and source machine data are pushed to the target virtual machine.
Further, after the step S200, the method further includes: judging whether the operating system corresponding to the target virtual machine supports the virtual equipment with the highest performance or not, and changing the operating system corresponding to the target virtual machine according to a judging result.
It should be noted that, after detecting and adjusting the hardware configuration of the target virtual machine, in order to avoid occurrence of a compatibility failure caused by a mismatch condition between the operating system and the hardware configuration, and affect data transmission, before performing data pushing, it is necessary to detect whether the operating system of the target virtual machine supports a virtual device with the highest performance, where the virtual device refers to a virtual hardware device, for example: disk controller, network adapter, mouse controller, keyboard controller, video card adapter, etc.
It should be understood that the determination result includes two results, that is, the virtual device supporting the highest performance and the virtual device not supporting the highest performance, and if the operating system running in the target virtual machine does not support the high-performance virtual device, the operating system in the target virtual machine is changed.
The step of judging whether the operating system corresponding to the target virtual machine supports the virtual device with the highest performance or not, and changing the operating system corresponding to the target virtual machine according to the judging result comprises the following steps: when the operating system corresponding to the target virtual machine does not support the virtual equipment with the highest performance, reading a preset operating system from a preset virtual mirror space; changing the operating system corresponding to the target virtual machine into the preset operating system.
It should be noted that the preset virtual image space may be a preset virtual image space for storing configuration information related to a preset operating system corresponding to the virtual machine, where the preset operating system includes, but is not limited to, a data receiving system, where the data receiving system refers to an operating system that is used by the target virtual machine to support high-performance virtual devices in a data pushing stage, and running a data receiving module in the operating system, where the operating system and the data receiving module therein are referred to as a data receiving system, and the virtual image space may be a control that stores configuration information in a form of a virtual optical disc image, a virtual magnetic disc image, or a px boot image.
It can be understood that if the operating system running in the target virtual machine does not support the high-performance virtual device, the operating system in the target virtual machine is changed to run the data receiving module in the data receiving system, so that the target virtual machine can be used as a disk to store data.
In a specific implementation, when an operating system corresponding to a target virtual machine does not support a virtual device with highest performance, a preset operating system (such as a data receiving system) is read from a preset virtual image space, a guiding mode of the target virtual machine is modified to be the corresponding image, the operating system corresponding to the target virtual machine is changed to be the preset operating system, and the target virtual machine is restarted.
In the embodiment, when a data migration instruction is received, whether the hard disk type and the network card type of the target virtual machine meet the highest performance configuration condition or not is detected; according to the detection result, the target virtual machine is configured and adjusted according to the highest performance supported by the hard disk type and the network card type; and transmitting the data to be migrated to the target virtual machine after configuration adjustment. Because the hardware configuration type of the target virtual machine is dynamically adjusted, so that the hardware configuration of the target virtual machine supports the highest performance, compared with the low-performance configuration in which the target virtual machine is consistent with the source machine because the source machine does not support the high-performance configuration in the prior art, the data transmission speed is low, and the disaster recovery efficiency is low.
Referring to fig. 5, fig. 5 is a flowchart illustrating a third embodiment of the data migration method according to the present invention, and the third embodiment of the data migration method according to the present invention is proposed based on the first embodiment shown in fig. 2.
In this embodiment, after the step S30, the method further includes:
step S40: and when a service system switching instruction is received, detecting whether the current hard disk type and the current network card type of the target virtual machine are matched with the operating system of the target source machine, and deploying the system corresponding to the target virtual machine according to a matching result.
It should be noted that, after data migration is completed, when the operating system and the service system of the target virtual machine need to be started, the source service needs to be switched to the target data center, so that the continuity of the service is ensured, and the types of the hard disk and the network card of the switched target virtual machine may not be consistent with the use types in the data pushing stage. Thus requiring reconfiguration of the operating system and hardware configuration type of the target virtual machine.
It should be understood that when switching service systems, it is first required to check whether the current hard disk and network card type of the target virtual machine are matched with the operating system of the target source machine, so that the service system switching operation of the source machine can be completed on the target virtual machine, and therefore, the system corresponding to the target virtual machine needs to be deployed according to the matching result.
Further, in order to ensure service continuity, the target virtual machine is configured when the system is switched, and the step S50 further includes: when a service system switching instruction is received, detecting whether the current hard disk type and the current network card type of the target virtual machine are matched with an operating system of a target source machine or not; when the operating system of the target source machine is not matched with the current hard disk type and the current network card type of the target virtual machine, the hard disk type and the network card type of the target virtual machine are adjusted according to the hardware configuration type corresponding to the target source machine; and deploying the system corresponding to the target virtual machine according to the source machine operating system corresponding to the target source machine.
When the service system switching is identified, acquiring the hardware equipment information of the target source machine, and firstly checking whether the current hard disk and network card type of the target virtual machine are matched with the operating system of the source machine; because the disaster recovery (migration) task is a high-performance type hard disk and a network card used in the data pushing stage, if the operating system of the target source machine does not support high performance, the hard disk and the network card type of the target virtual machine are required to be set to be a hardware configuration type matched with the operating system of the source machine by calling the API interface of the application program, so that the service system can normally operate after the target virtual machine is switched; and changing the guiding of the target virtual machine from a data receiving system to a source machine operating system according to the requirement, and shutting down or restarting the target virtual machine.
In the specific implementation, after the hardware configuration type and the corresponding operating system of the target virtual machine are dynamically adjusted, the target virtual machine is powered off or restarted according to the requirement, so that the target virtual machine can operate according to the requirement when the service system is switched. To further illustrate the method for reminding disaster recovery efficiency by dynamically adjusting the hardware configuration type of the target virtual machine in the data pushing stage, reference may be made to a workflow diagram shown in fig. 6, in which before data pushing is performed, the hard disk type and the network card type of the target virtual machine are checked, if the hard disk and the network card of the target virtual machine are found to be not of a high performance type, the hard disk and the network card of the target virtual machine are set to be of a high performance, so that the target virtual machine can perform high performance data pushing, and the data transmission time in the disaster recovery (migration) process is shortened; after the data push is finished, the disaster recovery (migration) task can perform the following steps as required: waiting for the next push, or waiting for switching, or switching immediately, etc.; when the switching system comes, the service system needs to be switched from the source machine to the target virtual machine, the switching stage is indicated to enter, and because the hard disk and the network card are both of high-performance type, but because some operating systems are hard disks and network cards which do not support the high-performance type, whether the operating system of the source machine can use the high-performance hard disk type and the network card type needs to be detected first, if so, the operation is not changed, otherwise, the hard disk and the network card type of the target virtual machine needs to be set to be of a hardware configuration type matched with the operating system of the source machine through calling an API (application program interface), and the target virtual machine and the source machine are ensured to keep consistent, normal disk read-write operation can be performed, and then a conventional switching step is performed.
In the embodiment, when a data migration instruction is received, the hardware configuration type of the target virtual machine is detected; configuring and adjusting the target virtual machine according to the highest performance supported by the hardware configuration type; and transmitting the data to be migrated to the target virtual machine after configuration adjustment. And when a service system switching instruction is received, detecting whether the current hard disk type and the current network card type of the target virtual machine are matched with the operating system of the target source machine, and deploying the system corresponding to the target virtual machine according to a matching result. Because the hardware configuration type of the target virtual machine is dynamically adjusted, so that the hardware configuration of the target virtual machine supports the highest performance, compared with the low-performance configuration in which the target virtual machine is consistent with the source machine because the source machine does not support the high-performance configuration in the prior art, the data transmission speed is low, and the disaster recovery efficiency is low.
In addition, in order to achieve the above object, the present invention also proposes a storage medium having stored thereon a data migration program which, when executed by a processor, implements the steps of the data migration method as described above.
Referring to fig. 7, fig. 7 is a block diagram illustrating a first embodiment of a data migration apparatus according to the present invention.

In the embodiment, when a data migration instruction is received, the hardware configuration type of the target virtual machine is detected; configuring and adjusting the target virtual machine according to the highest performance supported by the hardware configuration type; and transmitting the data to be migrated to the target virtual machine after configuration adjustment. Because the hardware configuration type of the target virtual machine is dynamically adjusted, so that the hardware configuration of the target virtual machine supports the highest performance, compared with the low-performance configuration in which the target virtual machine is consistent with the source machine because the source machine does not support the high-performance configuration in the prior art, the data transmission speed is low, and the disaster recovery efficiency is low.
Optionally, the configuration detection module 10 is further configured to detect, when receiving a data migration instruction, whether the hard disk type and the network card type of the target virtual machine meet a highest performance configuration condition;
