how can i get TR-4476 for aggregate deduplication

Martina_Lu — Wed, 04 Jun 2025 10:09:23 GMT

i read some documents about aggregate deduplication on ONTAP 9.2 latter, but the related link (https://www.netapp.com/us/media/tr-4476.pdf) is invalid.

Could you provide some details and documents about aggregate deduplication ?
