Managing Data Reduction
Data Reduction uses compression and deduplication to decrease the amount of disk space used by volume data. Compression
reduces the amount of space used by a volume by encoding data. Deduplication nds duplicate pages and removes them, conserving
the disk space that would be used by additional copies. When deduplication is used, compression is also applied to a volume.
NOTE: Data Reduction is available in Storage Center version 7.0 or later.
Data Eligible for Data Reduction
To reduce the impact of Data Reduction on read and write operations, a limited amount of data is eligible for compression and
deduplication. Data Reduction Input limits the type of data that is eligible for Data Reduction. The following options are available for
Data Reduction Input.
• Inaccessible Snapshot Pages – Allows Data Reduction to process data frozen by a snapshot and made inaccessible by new data
written over the original data in the snapshot.
• All Snapshot Pages – Allows Data Reduction to process data frozen by a snapshot.
Change the Data Reduction Input
Change the Data Reduction Input for a volume to change the type of data that compression and deduplication reduces.
Prerequisite
Data Reduction must be applied to the volume.
