If no data migration plan is set, with SmartTier enabled, there will be no data movement at al between tiers.

SmartTier is an intelligent data tiering feature designed to automatically migrate data based on its activity level (heat). When SmartTier is enabled, it continuously analyzes I/O patterns. While a user can configure a specific "data migration plan" or policy to define the schedule for when data relocation occurs (e.g., during off-peak hours), the system uses a default migration policy if no custom plan is configured. Therefore, data movement between tiers will still occur based on this default system schedule. The absence of a user-defined plan does not halt the core functionality of SmartTier.

The statement "True" is incorrect because it wrongly implies that SmartTier is a passive feature that requires explicit, user-defined scheduling to perform any data migration. This contradicts the fundamental purpose of an automated, intelligent tiering solution, which is to manage data placement dynamically with minimal administrative overhead. SmartTier is designed to function "out-of-the-box" using a default policy.

"SmartTier Feature Guide for Block

" Section: "Working Principles

" Subsection: "Data Migration." This section details that data migration is triggered based on a policy

which includes a default policy that runs periodically if a custom one is not specified by the administrator.

Chapter: "Key Features of Block Storage

" Module: "SmartTier Intelligent Data Tiering." The courseware explains that SmartTier operates based on I/O monitoring and data analysis

followed by data relocation. It clarifies that a migration policy dictates the timing of the relocation

and a system-default policy is applied in the absence of a user-configured one

ensuring data movement still happens.

Section: "Provisioning > SmartTier Policy > Creating a SmartTier Policy." The documentation for creating a policy notes the existence of system defaults and explains that the policy's purpose is to control the timing and execution window of the migration

not to enable the migration capability itself.
