How do I enable TSSE on volumes created prior to 9.8
Applies to
- Temperature Sensitive Storage Efficiency(TSSE)
- ONTAP 9.8+
- AFF
Answer
- ONTAP 9.8 introduced Temperature Sensitive Storage Efficiency (TSSE) on newly created volumes on AFF platforms.
- Existing volumes created prior to upgrading to ONTAP 9.8 or 9.9 did not have TSSE enabled
- Starting in ONTAP 9.10.1, TSSE can be enabled on existing volumes
- The volume efficiency modify command includes the storage-efficiency-mode parameter to set as default or efficient
- Refer to Temperature-sensitive storage efficiency overview for the difference between these two options
- If desired to set TSSE enabled for specific volumes, use the volume efficiency modify command with storage-efficiency-mode set to efficient
- Following values are possible for storage-efficiency-mode during volume efficiency modify:
- default - Volume is having file based compression scheme
- efficient - Volume is having TSSE based compression scheme
- Setting "Storage-efficiency-mode" to "efficient" is same as enabling TSSE using "volume efficiency modify" ("application-io-size" will be set as "auto") and also all forms of deduplication will be enabled.
- Setting "Storage-efficiency-mode" to "default" is same as enabling file based compression ("application-io-size" will be set as "8k").
- Following values are possible for storage-efficiency-mode during volume efficiency modify:
