Configuring Cold Data Migration

Configuring Cold Data Migration

When a local storage system (new storage system) is used to replace a heterogeneous storage system (legacy storage system) to carry service data, the local storage system has a large amount of cold data (data that is rarely accessed), so the storage resource utilization is low and storage space is wasted. SmartVirtualization can work with SmartMigration to migrate cold data to the heterogeneous storage system. In this way, storage space on the local storage system is released.

Procedure for configuring cold data migration:
  1. Configure the heterogeneous storage system.

    Create a LUN in the heterogeneous storage system and map the LUN to the local storage system.

  2. Configure the local storage system.

    Create an eDevLUN to host the LUN created in the heterogeneous storage system.

  3. Configure SmartMigration.

    Configure SmartMigration in the local storage system to migrate cold data of the local storage system to the heterogeneous storage system. In this process, the LUN where cold data resides serves as the source LUN, and the LUN created on the heterogeneous storage system serves as the target LUN.
