Description

Technical Field

[0001] The present invention relates to the field of electronic communications, and in particular to a method and application of server business data migration. Background Art

[0002] Due to the need for localization under existing technologies and other reasons, many enterprises and departments are currently migrating businesses originally deployed in VMware environments to domestic environments. VMware environments and domestic environments are identical in hardware; the primary difference lies in the virtualization software technology deployed on the servers. Virtualization software technology abstracts server hardware into software functions and provides them to customers. Different virtualization technologies deployed on the same server can provide different software functions to customers. Some domestic virtualization software technologies abstract software functions from servers that not only provide similar service capabilities to VMware but also offer better compatibility with domestic chips and operating systems.

[0003] Migrating services from a VMware environment to a domestic environment requires redeploying domestic virtualization software on the VMware-deployed server. However, redeploying virtualization software often requires formatting disks, which can damage service data stored on the server disks. Therefore, during the service migration process, service data must be migrated to protect the integrity and security of the original service data.

[0004] Currently, common data migration solutions include transit server-based data migration, node replacement-based data migration, and node deletion-based data migration. All of these data migration technologies have technical flaws. The main technical flaws are that, for transit server-based data migration solutions, due to the high price of transit servers and external storage devices, only one set can be purchased due to cost constraints. In the case of multiple business migration sites, the migration process can only be carried out site by site, resulting in low migration efficiency. For node replacement-based data migration solutions, the number of data copies decreases during the node replacement process, thereby reducing data security. For node deletion-based data migration solutions, data needs to be migrated between different servers multiple times during the node deletion process. The more nodes that need to be deleted, the larger the amount of data to be migrated. Furthermore, after multiple node deletions and data balancing, the amount of data on each server node in the cluster is likely to be different, which will have a certain impact on the cluster's storage performance.

[0005] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0041] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0042] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0043] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] In the prior art, there are three common server data migration solutions: 1) Data migration based on a transit server. With the help of a transit server and an external storage device, all business data originally on the first environment is migrated to the external storage device of the transit server. After the server originally deployed with the first environment is transformed into a domestic environment, a new cluster is formed with the new server, and then the business data is migrated back to the new cluster from the external storage device of the transit server. 2) Data migration based on node replacement. A cluster is directly formed using a new server, and then the server nodes in the new cluster are replaced with the first environment server in turn. After each replacement, the data on the first environment server needs to be redistributed within the cluster before the next replacement can be performed. 3) Data migration based on node deletion. The first environment server and the new server are formed into a new cluster, and the business data on the first environment server is distributed to the entire cluster through the cluster's data balancing function, and then new servers equal to the number of first environment servers are deleted from the cluster one by one. Each time a server is deleted, it is necessary to wait for the data on the deleted server to be re-migrated to other servers in the cluster through the data balancing function, and the next server is processed after the migration is completed.

[0045] Example 1

[0046] like Figure 1 As shown, a method for migrating server business data in an embodiment of the present invention is introduced, and the method includes the following steps.

[0047] This embodiment takes the migration of business data from a first environment server to a second environment server as an example.

[0048] In step S101 , a second environment server cluster is created, wherein the second environment server cluster includes a plurality of second environment servers.

[0049] In this embodiment, the cluster configuration of server nodes can provide high availability and scalability, and multiple servers in the cluster maintain uninterrupted communication. When a node in the cluster is unavailable due to an error or maintenance, another node will immediately provide service to achieve fault tolerance.

[0050] In step S102 , when the data balancing function of the second environment server cluster is enabled, the business data on the first environment server is migrated to the plurality of second environment servers.

[0051] In this embodiment, the first environment server is connected to the second environment server cluster via a wired connection, and a migration tool is used to read the business data on the first environment server. This business data is then segmented using data striping technology, and combined with the data balancing function of the second environment server cluster, the business data is evenly written to the disks of each node in the first environment server. This operation avoids the use of expensive transit servers and external storage devices, thereby reducing costs.

[0052] In step S103, the data balancing function of the second environment server cluster is disabled.

[0053] In this embodiment, the cluster's data balancing function is to evenly write data to each disk by rebuilding the data layout. Disabling the cluster's data balancing function is to prevent data from being automatically distributed to newly added servers in the original first environment, which would cause uneven data distribution and affect storage performance.

[0054] In step S104, the first environment server is added to the second environment server cluster as a new node.

[0055] In this embodiment, all servers in the first environment are added as new nodes to the newly created second-stage server cluster, while the servers in the first environment are retained. Compared to data migration solutions based on node deletion that also retain servers in the first environment, this invention can reduce the number of data migrations and avoid the problem of uneven data distribution after migration.

[0056] In step S105 , the business data on the second environment server is migrated to the first environment server in parallel on a one-to-one basis, and the second environment server on which data migration has been completed is deleted.

[0057] In this embodiment, within a domestic server cluster, business data is migrated one-to-one in parallel between multiple first-environment servers and second-stage servers. This reduces the number of data operations, improves data migration efficiency, and avoids uneven data distribution after migration, which can affect cluster storage performance. After the data migration is complete, the second-environment servers that have completed the data migration are deleted, and the original first-environment servers and the second-environment servers that did not participate in the data migration are retained to form a new second-environment server cluster.

[0058] The first environment server includes a VMware environment server, and the second environment server includes another environment server including a localized environment server.

[0059] It should be noted that the present invention does not specifically limit the virtualization technology used by the first environment server and the second environment server, but only provides an application. The present invention is applicable to all servers in a cluster environment that can be implemented.

[0060] Example 2

[0061] like Figure 2 As shown, a method for migrating business data of a VMware environment server to a domestic environment server in an embodiment of the present invention is introduced, and the method includes the following steps.

[0062] In step S101 , a second environment server cluster is created, wherein the second environment server cluster includes a plurality of second environment servers.

[0063] In this embodiment, a second environment server cluster is created through server nodes, wherein the server nodes deploy the second environment virtualization technology.

[0064] In step S102 , when the data balancing function of the second environment server cluster is enabled, the business data on the first environment server is migrated to the plurality of second environment servers.

[0065] In this embodiment, the first environment server is connected to the second environment server cluster via a wired connection, and a migration tool is used to read the business data on the first environment server. This business data is then segmented using data striping technology, and combined with the data balancing function of the second environment server cluster, the business data is evenly written to the disks of each node in the second environment server. This operation avoids the use of expensive transit servers and external storage devices, thereby reducing costs.

[0066] Specifically, striping technology automatically balances I / O load across multiple physical disks. This technology splits a continuous block of data into equal-sized blocks and writes each segment to a different disk in the array. Striping ensures that business data is evenly written to each disk in the secondary environment server at each node during data read and write operations.

[0067] In step S103, the data balancing function of the second environment server cluster is disabled.

[0068] In this embodiment, the cluster's data balancing function is to evenly write data to each disk by rebuilding the data layout. Disabling the cluster's data balancing function is to prevent data from being automatically distributed to newly added servers in the original first environment, which would cause uneven data distribution and affect storage performance.

[0069] In step S104, the first environment server is added to the second environment server cluster as a new node.

[0070] In this embodiment, the original virtualization technology deployed on the first environment server is replaced with the second environment virtualization technology deployed on the second environment server cluster, so that the first environment server is transformed into a second environment server. The original first environment server transformed into the second environment server is retained.

[0071] Furthermore, through the cluster node adding function in the second environment virtualization technology, the transformed first environment server is added to the second environment server cluster as a new node.

[0072] In step S105 , the business data on the second environment server is migrated to the first environment server in parallel on a one-to-one basis, and the second environment server on which data migration has been completed is deleted.

[0073] In this embodiment, when the number of second environment servers is greater than or equal to the number of first environment servers, second environment servers with the same number as the first environment servers are selected for one-to-one parallel data migration, and the second environment servers performing data migration have the same number of disks as the first environment servers.

[0074] Specifically, the second environment server for data migration is connected to the first environment server through a wired connection, a migration tool is deployed on the first environment server and the business data on the second environment server is read; and data striping technology is used to cut the business data and evenly write the business data to the disk of the first environment server.

[0075] Furthermore, after deleting all the second environment servers that have completed data migration, the data balancing function of the second environment server cluster is re-enabled.

[0076] Example 3

[0077] like Figures 2 to 6 As shown, a specific example of a method for migrating server business data in an embodiment of the present invention is introduced.

[0078] This embodiment uses the VMware environment server as the first environment server and the domestic environment server as the second environment server, that is, introduces a specific method for migrating business data of the VMware environment server to the domestic environment server, which includes the following steps.

[0079] In step S201 , a domestic server cluster is created, wherein the domestic server cluster includes a plurality of domestic servers.

[0080] In this embodiment, the cluster configuration of server nodes provides high availability and scalability, ensuring uninterrupted connectivity between multiple servers within the cluster. If a node in the cluster becomes unavailable due to an error or maintenance, another node immediately provides service, achieving fault tolerance. The domestically produced servers are servers that have all deployed domestically produced virtualization technology, forming a domestically produced server cluster.

[0081] Specifically, a domestic server cluster is created by using one or more server nodes, wherein the server nodes deploy domestic virtualization technology, namely domestic servers. The present invention does not limit the method for creating the domestic server cluster and the domestic virtualization technology, and any achievable technology can be used.

[0082] like Figure 3 As shown, the data migration of two VMware environment servers D and E is used as an example to explain the embodiment of the present invention in detail. A new domestic server cluster is created by deploying three server nodes A, B, and C that use domestic virtualization technology.

[0083] In step S202, when the data balancing function of the domestic server cluster is turned on, the business data on the VMware environment server is migrated to the multiple domestic servers.

[0084] Specifically, based on the existing data migration solution based on transit servers, the present invention creates a new domestic server cluster, eliminating the need for expensive transit servers and external storage devices, thereby reducing costs. All business data on VMware environment servers is migrated to multiple domestic servers, and the business data is evenly distributed across the multiple domestic servers.

[0085] In this embodiment, the VMware environment server is connected to the domestic server cluster via a wired connection, and a migration tool is used to read the business data on the VMware environment server. The business data is segmented using data striping technology, and combined with the data balancing function of the domestic server cluster, the business data is evenly written to the disk of each node's domestic server. This operation avoids the use of expensive transit servers and external storage devices, thereby reducing costs.

[0086] like Figure 3 As shown, the business data on two VMware environment servers D and E are migrated to the newly established domestic server cluster. During the migration process, the two original VMware environment servers D and E are connected to the domestic server cluster via a wired connection, and then the migration tool is used to read the business data on servers D and E. The read business data is divided using data striping technology and evenly written to each disk of the domestic server on each node. At this time, the cluster's data balancing function can identify the distribution of business data on each disk, and if it is not evenly written to the disks of each node due to special reasons during the writing process, the data balancing function can evenly distribute the data to each disk by rebuilding the data layout. After the above operations, all business data on VMware environment servers D and E is evenly distributed on servers A, B, and C.

[0087] In step S203, the data balancing function of the domestic server cluster is turned off.

[0088] like Figure 4 The upper right corner shows that the cluster's data balancing function is disabled. This function evenly distributes data across disks by reconfiguring the data layout. Disabling this function prevents data from being automatically distributed to two newly added VMware servers, which could cause uneven data distribution and impact storage performance.

[0089] In step S204, the VMware environment server is added as a new node to the domestic server cluster.

[0090] In this embodiment, all VMware environment servers are added as new nodes to the newly built domestic server cluster, while the VMware environment servers are retained. Compared with the data migration solution based on node deletion, which can also retain VMware environment servers, this invention can reduce the number of data migrations and avoid the problem of uneven data distribution after migration.

[0091] Specifically, the original virtualization technology deployed in the VMware environment server is replaced with the domestic virtualization technology deployed in the domestic server cluster, thereby converting the VMware environment server into a domestic server. Using the cluster node addition function in the domestic virtualization technology, the converted VMware environment server is added to the domestic server cluster as a new node.

[0092] like Figure 5 As shown in the figure, after completing the data migration, the two servers D and E, which originally deployed the VMware environment, were re-deployed with the same domestic virtualization software as the server nodes, transforming them into domestic servers. Using the cluster node addition function in the domestic virtualization technology, the two transformed servers D and E were added as new nodes to the created domestic server cluster.

[0093] In a data migration solution based on node replacement, the number of data copies will decrease during the gradual replacement of nodes. Taking the data migration of two VMware servers as an example, during the process of node replacement, the data copies are changed from the original two copies to a single copy, resulting in reduced data security. In this embodiment, since the business data on the original VMware environment server has been completely migrated to the domestically produced servers in the new cluster, the situation in which the number of data copies decreases and security decreases in the node replacement solution is avoided. In addition, servers D and E have also been transformed into new domestically produced servers, the original data has been cleared, and the cluster has turned off the data balancing function, so the business data will not be automatically distributed to servers D and E after servers D and E join the cluster. Due to the above reasons, the two VMware environment servers D and E that join the cluster do not contain business data.

[0094] In step S205, the business data on the domestic servers are migrated one-to-one in parallel to the VMware environment server, and the domestic servers that have completed data migration are deleted to restore the data balancing function of the cluster.

[0095] In this embodiment, if the number of domestically produced servers is greater than or equal to the number of VMware environment servers, domestically produced servers with the same number of VMware environment servers are selected for one-to-one parallel data migration, and the domestically produced servers performing data migration and the VMware environment servers have the same number of disks. If there are two VMware environment servers, any two domestically produced servers need to be selected for data migration, with one VMware environment server connected to another domestically produced server, and the domestically produced servers and VMware environment servers have the same number of disks, thereby achieving one-to-one parallel migration.

[0096] Specifically, the domestic server for data migration and the VMware environment server are connected through a wired connection, a migration tool is deployed on the VMware environment server and the business data on the domestic server is read; and data striping technology is used to cut the business data and evenly write the business data to the disk of the VMware environment server.

[0097] Furthermore, after deleting all the domestic servers that have completed data migration, the data balancing function of the domestic server cluster is re-enabled.

[0098] like Figure 5 As shown, after adding VMware environment servers D and E to the created domestic server cluster, data from any two domestic servers can be migrated in parallel, one-to-one, to the transformed VMware environment servers D and E. This one-to-one parallel data migration avoids the issues of multiple data migrations and uneven data distribution after migration encountered in the node deletion solution, and only requires one migration, improving migration efficiency. The figure shows the migration of business data from domestic servers B and C to VMware environment servers D and E. The specific data migration process is illustrated using the migration of business data from domestic server C to VMware environment server E.

[0099] Connect two servers, C and E, via a wired connection. Then, deploy a migration tool on server E to read the data from the localized server C. Then, use data striping technology to evenly distribute the data across E's disks. Since servers C and E have the same number of disks, the data layout remains the same before and after the migration, so it can be understood as if the data is simply stored on hardware with the same configuration. This one-to-one migration ensures that the data remains evenly distributed across the cluster's server nodes after the migration is complete. After the one-to-one migration, all business data originally stored in the VMware environment is evenly distributed across the five servers A, B, C, D, and E. The business data on servers B and C is identical to that on servers D and E.

[0100] like Figure 6 As shown in the figure, after the one-to-one parallel data migration is complete, the two domestically produced servers B and C that completed the data transfer are removed from the cluster, and the cluster's data balancing function is restored. Since the data on servers D and E is identical to the business data on servers B and C, deleting them does not cause any loss of the original VMware environment's business data. This eliminates the need to wait for data rebalancing after node deletion, as is required in node-deletion-based data migration solutions. Furthermore, since the data balancing function is disabled, the data on server A will not be automatically migrated to other nodes during the entire migration process, ensuring the consistency and integrity of business data on nodes not participating in the data migration. At this point, all business data on servers D and E in the original VMware environment, originally distributed across servers A, B, and C, is now distributed across servers A, D, and E. The new cluster consisting of servers A, D, and E has received all the business data from the original VMware environment, completing the data migration.

[0101] The method for migrating server business data according to the embodiment of the present invention can solve the problem of high equipment cost. By building a new cluster in the second environment to migrate data, the cost of data migration is reduced, and concurrent migration of multi-site business data can be performed at a lower cost. Through one-to-one parallel migration between servers in the cluster, the number of data operations is reduced and the data migration efficiency is improved. By keeping the number of data copies unchanged during the entire migration process, the security of data during data migration is improved and the risk of migration is reduced. By flexibly turning on and off the data balancing function of the cluster, the problem of uneven data distribution on each server node in the cluster after the data migration is completed, thereby affecting the cluster storage performance, is avoided, and the impact of data migration on the cluster storage performance is reduced. It can be applied to the scenario of migrating the business data of VMware environment servers to domestic environment servers, and has wide applicability.

[0102] like Figure 7 As shown, a device for migrating server business data according to a specific embodiment of the present invention is introduced.

[0103] In an embodiment of the present invention, the apparatus for migrating server service data includes a cluster creation module 701 , a data migration module 702 , a function shutdown module 703 , a cluster addition module 704 and a parallel migration module 705 .

[0104] The cluster creation module 701 is configured to create a second environment server cluster, wherein the second environment server cluster includes a plurality of second environment servers.

[0105] The data migration module 702 is configured to migrate the business data on the first environment server to the plurality of second environment servers when the data balancing function of the second environment server cluster is enabled.

[0106] The function closing module 703 is used to close the data balancing function of the second environment server cluster.

[0107] The cluster adding module 704 is used to add the first environment server as a new node to the second environment server cluster.

[0108] The parallel migration module 705 is configured to perform a one-to-one parallel migration of the business data on the second environment server to the first environment server, and delete the second environment server on which data migration has been completed.

[0109] The cluster creation module 701 is further configured to create a second environment server cluster using server nodes, wherein the server nodes deploy the second environment virtualization technology.

[0110] The data migration module 702 is also used to: connect the first environment server to the second environment server cluster through a wired connection, and use the migration tool to read the business data on the first environment server; and divide the business data through data striping technology, and combine the data balancing function of the second environment server cluster to evenly write the business data to the disk of the second environment server of each node.

[0120] The method for migrating server business data according to the embodiment of the present invention can solve the problem of high equipment cost. By building a new cluster in the second environment to migrate data, the cost of data migration is reduced, and concurrent migration of multi-site business data can be performed at a lower cost. Through one-to-one parallel migration between servers in the cluster, the number of data operations is reduced and the data migration efficiency is improved. By keeping the number of data copies unchanged during the entire migration process, the security of data during data migration is improved and the risk of migration is reduced. By flexibly turning on and off the data balancing function of the cluster, the problem of uneven data distribution on each server node in the cluster after the data migration is completed, thereby affecting the cluster storage performance, is avoided, and the impact of data migration on the cluster storage performance is reduced. It can be applied to the scenario of migrating the business data of VMware environment servers to domestic environment servers, and has wide applicability.
