A method for cross-physical-area multi-platform complex data center overall migration

Abstract

The invention provides a method for cross-physical-area multi-platform complex data center overall migration, comprising the following steps: deploying VPLEX equipment, carrying out Active-Active processing on core storage, implementing Active-Active storage packaging on a host level, and realizing pairwise Active-Active mirroring on service system data stored in each storage; employing a logicalcorrelation mapping analysis technology to design scientific and reasonable migration batches and a plan list for the problem that systems and equipment of all old machine rooms are closely associatedand cannot be migrated in batches, and implementing batch migration according to the plan and the list; cloning systems on old equipment a virtual machine on a virtualization platform by using a PtoVtechnology provided in a server virtualization technology, and implementing migration of a host machine on the virtualization platform by depending on an HA technology of the virtualization platform;using dual-computer hot standby technology to provide two physical servers for an important system with a single-point fault for deploying a database 58 and an application 59 respectively, meanwhile,establishing a cluster environment is established. Therefore, the data safety is improved.

Description

technical field [0001] The invention belongs to the technical field of computer data, and relates to storage virtualization technology, logic correlation analysis technology, server virtualization technology and dual-computer hot standby technology. Background technique [0002] The overall migration of a complex data center across physical regions and multiple platforms involves complex situations and many considerations. It is a comprehensive system engineering, and there are the following technical problems: 1) The migration of core data storage is the bottleneck of complex data center migration. The core storage stores all business system data, and it is impossible to stop the storage for migration, and there are strict requirements on the business shutdown window. At the same time, the core storage has no redundancy, and there is a single point of failure. Once a problem occurs during the migration process, all related important systems will be destroyed. Therefore, how...

[0002] The overall migration of a complex data center across physical regions and multiple platforms involves complex situations and many factors to consider. It is a comprehensive system engineering with the following technical problems: 1) The migration of core data storage is the bottleneck of complex data center migration

The core storage stores all business system data, and it is impossible to stop the storage for migration, and there are strict requirements on the business shutdown window. At the same time, the core storage has no redundancy, and there is a single point of failure. Once a problem occurs during the migration process, all related important systems will be destroyed. Unable to use, so how to efficiently migrate core data storage has become a major difficulty

2) How to migrate systems and devices that are closely related in different computer rooms in batches

3) How to migrate systems and equipment with single point of failure and serious aging

If there are many single-point failures in the systems and equipment involved in the migration, including core business systems, the applications and databases of these systems are deployed on the same server. Deployment takes time, which will not only affect the business, but also cannot meet the requirements of downtime. At the same time, the system and equipment are seriously aging, and there are risks in restarting and migrating. big difficulty

Therefore, when complex data centers across physical regions and multiple platforms need to be migrated as a whole, a single method is not easy to implement, and a comprehensive method needs to be studied
