Planning
This chapter describes how to plan the capacity, compatibility, and connection between the local storage system and compatible heterogeneous storage system before using SmartMigration to migrate data within a storage system or between storage systems.
Capacity Planning
Before using SmartMigration for a LUN, reserve 5 per mill of the LUN capacity in the storage pool where the LUN belongs to store metadata of the feature. To apply multiple features to a LUN, reserve 1% of the LUN capacity in the storage pool.
Compatibility Planning
SmartMigration works with SmartVirtualization to migrate data between storage systems. Therefore, you need to know which storage systems (including Huawei storage systems and mainstream third-party storage systems) are supported by SmartVirtualization in advance. You can obtain the information at Huawei Storage Interoperability Navigator.
Connection Planning Between the Local Storage System and Compatible Heterogeneous Storage System
OceanStor Dorado V6 series storage systems connect to heterogeneous storage systems in different modes to implement data migration using SmartMigration and SmartVirtualizaiton. Table 2-1 provides details.
