Is this still true with the single LUN performance improvements in ONTAP 9.9.1?
Perhaps not, but we still hit single affinity bottlenecks. Flexgroups are the obvious answer to that.
Asked Bobby to help take a look.
@netapp-jyhshing - Please update status or close if work is complete.
@netapp-jyhshing - What is the status of this issue?
Let me check with Bobby. Thanks.
Thanks for pointing this out. @MrObvious I am fixing it. "Place database files in a single FlexVol; don’t spread them across FlexVols". Not sure how it fell thru the crack.
Single LUN performance made significant improvement over past ONTAP releases, and could cover most of the DB use-cases in SMB, but I have seen customers running in challenges when they look for larger throughput [backups].
thank you @ntap-bmegan and @netapp-jyhshing
@MrObvious - The change is implemented.
Can we close the issue, or is additional work required?
I am good closing. was waiting for @MrObvious

This may require consultation with O'Mahoney or Jeff Steiner, but single LUN/Volume setups on anything more than like 4-6 CPU cores really drag with performance. Multiple volumes/LUNs are better to avoid single affinity/scsit_lu thread bottlenecks.
