Hi,
I'm migrating 3 old FAS 2554 on 2 new FAS 2720 (with many more disks but always HDD) with ONTAP 9.9.1. Old and new FAS have both Flash Pool.
When creating a volume on FAS 2720 always enables efficiency for any volume (Background deduplication) but since I have only HDD, and my data is already gzipped on the source I'm not interested in any efficiency that has also a negative effect on performance. So I have to disable on every new volume, or when using SnapMirror I have to create "relationship", and before starting, disables efficiency on new created volume, that ONTAP enables by default.
cluster4::> volume efficiency show
Vserver Volume State Status Progress Policy
---------- ---------------- --------- ----------- ------------------ ----------
svm01-cl4 Vault Disabled Idle Idle for 409:28:27 -
svm02-cl4 Control Disabled Idle Idle for 147:24:48 -
So my questions are:
- why efficiency is enabled by default also on non AFF?
- Can I disable efficiency at system/global level?
- Is sufficient a " volume efficiency stop VolName" to disable?
Thanks
