Managing Data Reduction

Data reduction is enabled on a per NAS volume basis. The FluidFS cluster supports two types of data reduction:

•Data deduplication: Uses algorithms to eliminate redundant data, leaving only one copy of the data to be stored. The FluidFS cluster uses variable-size block level deduplication as opposed to file level deduplication.

•Data compression: Uses proprietary algorithms to reduce the size of stored data.

Data reduction also provides space savings for snapshots taken after files have been reduced.

By default, data reduction is applied only to files that have not been accessed or modified for 30 days, in order to minimize the impact of data reduction on performance. The minimum file size to be considered for data reduction processing is 64 KB. Data reduction is applied per NAS controller, that is, the same chunks of data that are owned by the different NAS controllers are not considered duplicates.

Because quotas are based on logical rather than physical space consumption, data reduction does not affect quota calculations.

In the event that you disable data reduction, data remains in its reduced state during subsequent read operations by default. You have the option to enable rehydrate‐on‐read when disabling data reduction, which causes “rehydration” (reversal of data reduction) of data on subsequent read operations. You cannot rehydrate an entire NAS volume with a single command, although you could accomplish this by reading the entire NAS volume.
