Description

This article describes how to enable inline deduplication on Non-AFF (All Flash FAS) aggregates

When enabling inline deduplicaiton on non-AFF systems, you are not seeing any savings returned.

On Non-AFF systems, inline deduplicaiton is disabled by default. To enable inline deduplication on volumes residing within an HDD/all-SSD (non-AFF) aggregate, the following hidden option needs to be set from the nodeshell : sis.idedup_allow_non_aff_hya on.
