Per volume basis.
From HPE ASE Storage solutions V4:
As indicated in Figure 2-36, Nimble uses a number of data reduction techniques and the most important are:
• Compression
– Offers highest compression rate (2.5 to three times) typical, as measured by customers
– Works together with SQL Server compression
– Runs inline
– Enabled per volume
• Deduplication
– Dedupe is excellent at detecting full or partial copies of databases and saving the space those copies would otherwise use (for example, Always On availability groups).
– Deduplication on SQL backups is typically 4 to 7 times as tested. Must be uncompressed from SQL (meaning Nimble must handle both compressions and deduplication).
– Runs inline
