Data compression is a Data ONTAP feature that enables you to reduce the physical capacity that is required to store data on storage systems by compressing the data blocks within a FlexVol volume or an Infinite Volume.
You must understand how data compression works, the types of data compression, and when you must run data compression to achieve maximum saving and performance from your storage system. You must also understand about the incompressible data detection feature to quickly identify the files and compression groups that cannot be compressed.
You must be aware of how to enable data compression on the volume, assign a compression type to a volume, and move between different types of compression.
You can use data compression on primary, secondary, and tertiary storage tiers.
