Requirement Analysis

Requirement Analysis

Before implementing data migration, analyze service requirements, make a service-related plan, and determine an implementation solution, so that data migration can be implemented as smoothly as possible.

Requirement Source

  • Service introduction

    An enterprise has three storage systems: Huawei OceanStor Dorado6000 V3, HDS USP-V storage system, and S5600T V100R005 storage system. When delivered, the OceanStor Dorado6000 V3 storage system has no default service running on it. In addition, the assets information management system and archive backup system are running on the other two storage systems respectively.

    • The asset management information system, which is served by an Oracle database, records the enterprise's asset information.
    • The archive&backup system archives service data that is infrequently accessed.

      Table 4-1 lists the hardware components of the asset management information system and the archive&backup system.

System Name

Hardware Component

Asset management information system

  • AIX-based application server
  • HDS USP-V storage system

Archive&backup system

  • AIX-based application servera
  • S5600T storage system V100R005b

a: The asset management information system and the archive&backup system run on the same AIX-based application server.

b: The S5600T only runs basic storage services. No value-added services are in use.

Figure 4-1 shows the network where the two service systems are deployed.

  • Service requirements

    As the enterprise's business keeps growing, an ever-increasing amount of asset management information needs to be recorded. In this example, the HDS USP-V has been used for a long time. Its lifecycle is about to end, and its storage space is about to be used up. The customer wants to migrate the asset management information system to an S5600T. The asset management information system stores non-critical data. Therefore, the S5600T can meet the performance requirement, and existing storage resources can be reused.

    Specific customer requirements are as follows:

    • Data be migrated to the S5600T non-disruptively.
    • Data be migrated during off-peak hours at night.
    • After data is migrated, the S5600T can take over the asset management information system from the HDS USP-V.

Requirement Analysis and Conclusions

It can be inferred from the customer requirements that an inter-storage-system data migration solution suits the customer. Huawei value-added features remote replication and SmartMigration can be used for data migration. Table 4-4 describes the data copy characteristics and typical application scenarios of these features.

Data migration

Impact of data migration on system services


Online data migration is implemented without affecting services.

  • Conclusion 1: The customer needs to migrate data between storage systems. It can be concluded from the preceding table that SmartMigration can address the need. However, the SmartMigration license is unavailable on the S5600T used by the customer. Therefore, the customer cannot use SmartMigration to migrate data from the HDS USP-V to the S5600T.
  • Conclusion 2: The customer wants online data migration. Therefore, SmartMigration is the perfect choice.
  • Conclusion 3: The customer requires data to be migrated during off-peak hours. Therefore, the migration speed can be set to High for higher data migration efficiency.

The S5600T does not contain a SmartMigration license. Therefore, the customer cannot use SmartMigration to migrate data from the HDS USP-V to the S5600T.

While the S5600T does not contain the relevant license, the OceanStor Dorado6000 V3 storage system purchased by the customer supports SmartVirtualization and SmartMigration. Therefore, data can be migrated using the following method:

  1. Use the OceanStor Dorado6000 V3 to host LUNs created on the HDS USP-V and the S5600T, and create eDevLUNs corresponding to these LUNs.
  2. On the OceanStor Dorado6000 V3, configure SmartMigration for eDevLUNs to migrate data.

The OceanStor Dorado6000 V3 is used as an example to describe configuration planning and operations.
