VNX data block deduplication can be enabled on each Pool.


1. To enable deduplication for a traditional RAID group LUN, you must first migrate it to the storage pool ).


2. Once deduplication is enabled, the LUN will be migrated to the deduplication container. After the migration is complete, the LUN will become Thin LUN.


The deduplicate container is the private space in the Pool. Currently, it supports up to 1 PB of space. When the first LUN in the Pool enables deduplication, it is created. When the last LUN is disabled, it is deleted. Each storage pool can only be composed of one deduplicated container.


The LUN with no deduplication enabled can exist in the same Pool as the LUN with deduplication enabled.
