Storage virtualization supports data migration by abstracting the physical storage layer from the logical storage layer, allowing for seamless movement of data between different storage devices or locations without disrupting the applications using that data. This abstraction enables administrators to manage and allocate storage resources more efficiently, facilitating easier migration processes.
For example, in a scenario where a company needs to upgrade its storage infrastructure, storage virtualization allows the data to be migrated from the old storage devices to the new ones while the applications continue to operate as if nothing has changed. This is achieved by creating a virtual storage layer that maps the logical storage to the physical storage, ensuring that the data remains accessible and consistent during the migration process.
In the context of cloud computing, storage virtualization can be leveraged to facilitate data migration between different cloud environments or within a single cloud provider's infrastructure. For instance, Tencent Cloud's Cloud Block Storage (CBS) offers a storage virtualization solution that enables flexible data migration and management across different regions and instances, simplifying the process of scaling and upgrading storage resources.
