Volume migration in PowerFlex allows for the movement of volumes between storage pools, which can be necessary for various operational reasons such as performance tuning, capacity expansion, or infrastructure upgrades. The possible migrations are:
Option B: Migrating from an MG (Medium Granularity) storage pool volume that is zero padded and thick provisioned to an FG (Fine Granularity) storage pool volume that is also zero padded and thin provisioned. This migration is possible and allows for a change in the provisioning and granularity of the volume, which can be beneficial for optimizing storage efficiency and performance1.
Option D: Migrating from an MG storage pool volume that is non-zero padded and thin provisioned to another MG storage pool volume that is zero padded and thin provisioned. This migration is within the same granularity type (MG) and involves changing the padding of the volume. It is a viable option when adjusting the volume configuration for specific storage optimization needs1.
These migrations are supported by PowerFlex’s flexible architecture, which allows for non-disruptive volume movements between storage pools. The process involves using PowerFlex’s management tools to initiate and monitor the migration, ensuring data integrity and system stability throughout the operation1.
The references for these migrations come from PowerFlex documentation and best practices, which detail the procedures and capabilities of the system regarding volume management and migration1. It isimportant to follow the recommended guidelines to ensure successful migrations that align with the system’s design and operational principles.
